Abstract:

O objetivo deste estudo foi verificar o efeito da suplementação de creatina sobre o desempenho nos testes de Wingate de 10 e 30 segundos além da sua influência na concentração de lactato, ureia, creatinina e massa corporal de indivíduos fisicamente ativos. Para realização da pesquisa foram selecionados nove voluntários, sendo divididos dentro de dois grupos utilizando o procedimento duplo-cego: grupo creatina (n = 4) e grupo placebo (n = 5). A suplementação foi realizada via oral durante 10 dias, sendo que o grupo creatina ingeriu 20g de creatina (4x ao dia) nos primeiros cinco dias, seguida de uma ingesta de 5g/dia até o 10º dia. O grupo placebo recebeu a mesma dosagem, porém de maltodextrina como placebo. O protocolo de teste realizado antes e após o período de suplementação constou de um teste de Wingate adaptado de 10 segundos, seguido de um intervalo de 20 minutos para aplicação de um teste de Wingate de 30 segundos. Foram coletadas amostras de sangue antes e após o período de suplementação para análise de creatinina e ureia, lactato em repouso, 90 segundos após o teste de 10 segundos e 180 segundos após o teste de 30 segundos. A suplementação de creatina promoveu um aumento significativo (p < 0,05) na potência máxima durante o teste de 30 segundos, na potência média no teste de 10 segundos, além da concentração de creatinina. Os resultados sugerem que a suplementação de creatina pode melhorar o desempenho dos indivíduos durante exercício de alta intensidade e curta duração realizado no cicloergômetro, mas produz aumento da concentração de creatinina em repouso.

Abstract:

Introdução: O futebol americano é caracterizado por um jogo de conquista de território que exige constantes ações de elevada intensidade em curtos períodos de intervalo durante toda a partida. Objetivo: Analisar o salto vertical com contramovimento, sob a indução de fadiga e os efeitos da coordenação articular do movimento sob a altura saltada em atletas de futebol americano. Metodologia: nove atletas amadores de futebol americano (25,22 ± 4,80 anos, 179,67 ± 6,15 cm e 89,78 kg ± 23,78 kg) realizaram um conjunto de testes compostos por salto vertical máximo, protocolo de fadiga Wingate, e novas tentativas de saltos máximos imediatamente após o termino da indução a fadiga, 30 segundos e 60 segundos após. Resultados: Houve diferença na altura máxima atingida no salto e coordenação de joelho e tornozelo esquerdo entre pré e imediatamente após o teste de Wingate. Correlações moderadas entre altura saltada e extensão máxima do quadril esquerdo e máxima extensão de tornozelo direito. Simetria bilateral foi mantida durante todo o teste. Conclusão: alterações biomecânicas do salto são verificadas principalmente logo após indução da fadiga. Parece que os atletas de futebol americano conseguem recuperar-se em curto período de tempo após indução a fadiga e voltar ao desempenho do salto inicial, ao mesmo tempo que mantém simetria do movimento.

Abstract:

O objetivo do presente estudo foi analisar a validade dos parâmetros de potência absolutos e relativos do Running-based Anaerobic Sprint Test (RAST) com base no teste de Wingate (WAnT). Doze voluntários do sexo masculino com idade de 25,50 anos (± 2,32) realizaram os testes RAST e WAnT. Foram observados valores significativos (p < 0,01) de correlação para a potência máxima absoluta (r = 0,76) e para a potência média absoluta (r = 0,74) dos testes, entretanto, os valores relativos apresentaram correlações não significativas (r = 0,54 e 0,27 respectivamente). Todos os parâmetros analisados apresentaram diferenças significativas (p < 0,01) na comparação entre WAnT e RAST. Desta forma, os resultados sugerem que apenas os parâmetros de potência absoluta do RAST são válidos. Assim ao aplicar o RAST para avaliação e/ou prescrição de treinamento, ou em pesquisas científicas, devem ser usados preferencialmente os parâmetros absolutos do teste.

Abstract:

Com o objetivo de investigar os efeitos da suplementação aguda com creatina no desempenho da potência anaeróbia de atletas de elite do mountain bike, 20 atletas em período básico do macrociclo de treinamento foram distribuídos aleatoriamente (duplo-cego) em dois grupos: placebo (PLA, n = 10) e creatina (CRE, n = 10). Foram avaliados quanto à composição corporal (pesagem hidrostática) e potência anaeróbia (teste de Wingate - TW) antes (PRÉ) e depois (PÓS) de sete dias de suplementação. A creatina ou maltodextrina foi usada em três doses diárias de 0,3g/kg de massa corporal diluídos em meio líquido adoçado. Não foram observadas diferenças significativas nas variáveis morfológicas após sete dias de suplementação (PRÉ x PÓS), e os grupos não diferiram apesar da variação percentual (Δ%) contrária (positiva para o grupo CRE e negativa para o PLA). A potência anaeróbia pico (PP) e o instante da potência pico (IPP) aumentaram e o índice de fadiga diminuiu do PRÉ para o PÓS-testes no grupo CRE, enquanto que o grupo PLA não apresentou diferenças significantes. A PP apresentou forte tendência em ser maior e o IPP foi maior no grupo CRE comparado com o PLA. Conclui-se que existem evidências de que a suplementação com creatina (0,3g/kg) em curto prazo (sete dias) pode retardar o IPP (CRE 3,0 ± 0,5/3,6 ± 0,8 Δ%= 20%) no teste de Wingate em atletas de elite do mountain bike, sugerindo que a suplementação com creatina pode melhorar o desempenho físico quanto à potência anaeróbia durante o trabalho de alta intensidade e curta duração.

Abstract:

O principal objetivo deste estudo foi mostrar alguns índices de aptidão funcional em 24 jogadores de futebol da Seleção Nacional da Jamaica, com média de idade de 23,9 ± 3,7 anos, equipe pré-classificada para a Copa do Mundo da França. Todos os atletas foram submetidos a uma bateria de testes que constou de: 1) avaliação da potência, resistência muscular e o índice de fadiga no teste de Wingate, realizado numa bicicleta computadorizada da marca Cybex, modelo Bike; 2) teste isocinético computadorizado de membros inferiores no equipamento da marca Cybex, modelo 1200; 3) avaliação da flexibilidade pelo teste de Wells e Dillon; 4) exames laboratoriais; e 5) avaliação odontológica, realizada através de exames clínicos num consultório da marca Funk modelo MLX Plus. Os seguintes parâmetros e os resultados encontrados foram: Wingate: potência pico corrigida pelo peso = 11,8 ± 1,8w.kg-1; potência média = 9,1 ± 1,2w.kg-1; índice de fadiga = 46,2 ± 15,2%; Flexibilidade = 19,8 ± 4,6cm; Exames laboratoriais: urina tipo I; fezes; hemoglobina = 14,3 ± 1,0g%; ferro = 104 ± 29ng/dl; ferritina = 81,8 ± 41,7ng/dl; transferrina = 502,5 ± 113,5ug/dl; hematócrito = 43,5 ± 2,9%; eritrócitos = 4,95 ± 0,40 milhões/m³; glicose = 91,0 ± 8,5mg/dl; Avaliação odontológica: tártaro em 5 (21%); cáries em 24 (100%); gengivites em 10 (42%); endodontia em 3 (12,5%); pulpites em 1 (4%); diastema em 2 (8%); heterotópicos em 13 (54%); extrações realizadas em 14 (58%); extrações não realizadas em 4 (17%); obturações em 4 (17%); próteses em 16 (67%); a profilaxia estava sendo feita em 17 (71%) dos atletas examinados; Desempenho isocinético: torque de MMII direito a 60°S-1 na extensão = 290,4 ± 95,6Nm; na flexão = 216,1 ± 31,4Nm; torque de MMII esquerdo a 60°S-1 na extensão = 291,6 ± 62,5Nm; na flexão = 205,8 ± 35,8Nm. CONCLUSÃO: Apesar da falta de estrutura tecnológica do futebol jamaicano, os resultados demonstraram que os índices de aptidão funcional dos futebolistas avaliados neste estudo foram semelhantes aos de jogadores verificados no Centro de Medicina Integrada da Associação Portuguesa de Desportos.

Abstract:

O principal objetivo deste estudo foi mostrar a importância da avaliação funcional como procedimento utilizado no controle fisiológico do treinamento físico de futebolistas profissionais em pré-temporada. Foram avaliados e posteriormente concentrados na cidade de Águas de Lindóia, Estado de São Paulo, por 16 dias, 23 jogadores pertencentes ao Departamento de Futebol Profissional da Associação Portuguesa de Desportos, em preparação para o Campeonato Paulista, edição 1999. Todos foram submetidos a uma bateria de testes que constou de avaliação: cardiorrespiratória e metabólica, odontológica, isocinética de membros inferiores, percentagem de gordura corpórea, da potência anaeróbia pelo teste de Wingate e testes de campo. Os seguintes resultados e os parâmetros avaliados foram: no limiar ventilatório 2 (LV2): VO2 = 49,09 ± 4,83ml.kg-1.min-1;%VO2 = 82,7 ± 5,8; velocidade de corrida = 12,8 ± 0,9km.h-1; FC = 174 ± 9bpm; no exercício máximo: V E BTPS = 137,3 ± 11,3L.min-1; velocidade de corrida = 17,6 ± 0,7km.h-1; FC = (191 ± 8bpm); VO2 pico = 59,28 ± 3,52ml.kg-1.min-1; lactato = 10,5 ± 1,5mM. Teste de Wingate: potência pico = 13,5 ± 1,1w.kg-1; potência média = 10,1 ± 0,6w.kg-1; índice de fadiga = 53,0 ± 7,7%. Teste isocinético: velocidade angular da articulação do joelho da perna direita na extensão e flexão a 60°S-1 = 298 ± 72 e 198 ± 44Nm, respectivamente; a 300°S-1 extensão e flexão = 137 ± 32 e 121 ± 26Nm, respectivamente. Velocidade angular da articulação do joelho da perna esquerda na extensão e flexão a 60°S-1 = 272 ± 62 e 185 ± 45Nm, respectivamente; a 300°S-1 extensão e flexão = 138 ± 28 e 122 ± 27Nm, respectivamente. A intensidade dos treinamentos aeróbio e anaeróbio foi controlada em campo por medidas de lactato, utilizando-se lactômetro portátil. O treinamento de musculação foi realizado a 60% da carga máxima para cada exercício. Os exercícios de alongamento e na piscina (hidroginástica) foram exaustivamente realizados pelos jogadores. Em média, cada sessão (manhã e tarde) durou 120 minutos. Portanto, pelo pouco tempo destinado a essa fase de preparação, a importância da avaliação funcional multidisciplinar justifica-se ainda mais, pois, a partir dos resultados, é possível detectar e corrigir possíveis deficiências, direcionando com objetividade o treinamento dos futebolistas.

Abstract:

O objetivo deste estudo foi avaliar a aptidão física dos praticantes do Le Parkour na cidade de Curitiba-PR. Participaram do estudo 13 sujeitos (19,46 ± 2,82 anos) do sexo masculino, praticantes da atividade há mais de seis meses. Foram realizadas medidas antropométricas e testes de aptidão física (teste de corrida vai-e-vem de 20 metros, de abdominal em um minuto, flexão e extensão dos braços, impulsão vertical e horizontal, sentar-e-alcançar e teste de Wingate). Os resultados foram analisados através de estatística descritiva (média e desvio padrão), sendo classificados com base em tabelas de referência para cada teste. Após avaliar o VO2máx, 53,85% dos praticantes estavam com valores considerados "baixa aptidão" e 46,15% apresentaram uma aptidão cardiorrespiratória adequada. Na força/resistência abdominal, 46,15% dos sujeitos foram classificados como "baixa aptidão" e 53,85% como "faixa recomendável". A potência de pico e a potência média foram consideradas como "regular" em todos os indivíduos. O índice de fadiga foi igual ou superior em 54% dos sujeitos. A flexibilidade foi avaliada como "baixa aptidão" em 69,23% da amostra. Na avaliação da força/resistência de membros superiores, observou-se que 84,62% estavam na "faixa recomendável". A partir dos resultados encontrados neste estudo, sugere-se que o Le Parkour, por ser uma atividade acíclica com ênfase em saltos e atividades de força nos braços, ocasionou melhores valores nos testes de impulsão horizontal, vertical e força de membros superiores. Entretanto, as demais variáveis avaliadas estavam abaixo da média, o que deve ser considerado na prescrição de exercícios e no acompanhamento dos indivíduos durante a prática da atividade. Sugerem-se novos estudos com amostras maiores e controle de treinamento dos praticantes de Le Parkour.

Abstract:

Objectivo: Analisar o perfil antropométrico e fisiológico dos triatletas portugueses e avaliar os parâmetros isocinéticos da força muscular nos membros inferiores. Métodos: A amostra foi composta de 12 atletas seniores masculinos (30,3 ± 3,8 anos; 70,2 ± 4,4 kg; 177,5 ± 5,4 cm; IMC 22,3 ± 0,6 e percentagem de gordura corporal 6,7 ± 1,9%). Foram avaliadas a impulsão vertical (sCM e sE), potência anaeróbia lática (WingateTest), força muscular em dinamómetro isocinético (velocidades angulares 90º/s e 360º/s), potência aeróbia máxima (tapete rolante). Utilizou-se a estatística descritiva, teste T de student para medidas repetidas e coeficiente de correlação de Spearman. Resultados: Foram encontradas correlações entre a massa corporal dos triatletas e a potência média (r = 0,57, p = 0,05) e máxima (r = 0,59, p = 0,04)obtidas no teste de Wingate. A potência média (relativa à massa corporal) correlacionou-se com os valores dos torques máximos concêntricos da articulação do joelho à 90º/s (r = 0,683, p = 0,014) e 360º/s (r = 0,622, p = 0,031). Os triatletas revelaram diferenças de 5,5% (p = 0,000) na razão I/Q à 360º/s e de 7,3% (p = 0,001) e 9,9% (p = 0,002) nos torques máximos concêntricos a 90º/s e 360º/s, respectivamente. Conclusão: Triatletas portugueses possuem perfis similares aos dos triatletas internacionais e evidenciam diferenças nos parâmetros isocinéticos da força muscular nos membros inferiores.Palavras-chave: atletas, triathlon, potência anaeróbia, potência aeróbia, dinamómetro.

Abstract:

O objetivo do presente estudo foi investigar o impacto de oito semanas de suplementação de creatina mono-hidratada (Crm) sobre o desempenho anaeróbio de adultos jovens treinados. Vinte e seis estudantes de educação física, do sexo masculino, saudáveis, foram divididos aleatoriamente em grupo creatina (GCr, n = 13; 22,5 ± 2,7 anos; 74,9 ± 6,8kg, 178,5 ± 4,8cm) e grupo placebo (GPl, n = 13; 22,9 ± 3,2 anos, 71,9 ± 11,3kg, 178,6 ± 4,0cm). Os indivíduos ingeriram em sistema duplo-cego doses de Crm ou placebo-maltodextrina (20 g.d-1 por 5 dias e 3 g.d-1 por 51 dias subsequentes). Ambos os grupos tiveram seus hábitos alimentares e os níveis de aptidão física controlados anteriormente. O teste anaeróbio de Wingate (TW) foi usado para avaliar o desempenho anaeróbio antes e após o período de ingestão de Crm ou placebo. Os índices de desempenho analisados foram: potência pico relativa (PPR), potência média relativa (PMR), trabalho total relativo (TTR) e índice de fadiga (IF). Para tratamento estatístico foi utilizado ANOVA, seguido pelo teste de post hoc Tukey, quando P<0,05. Não foram observadas diferenças significantes nos índices PPR, PMR, TTR e IF após o período de suplementação de Crm (P<0,05). Os resultados do presente estudo sugerem que a suplementação de Crm não parece ser um recurso ergogênico eficiente em esforços físicos de alta intensidade e curta duração que envolve uma única série.

Abstract:

A potência muscular apresenta relação com o tipo II de fibra muscular, com a capacidade glicolítica e com a coordenação motora, mas as características antropométricas podem estar relacionadas com esta aptidão. O objetivo deste estudo foi verificar a relação entre o pico de potência anaeróbia e o volume da coxa, assim como sua associação com outras variáveis antropométricas. Participaram do estudo 31 adolescentes do sexo masculino, praticantes de treinamento sistematizado de basquete, com idade média de 15,16 ± 1,11 anos, em estágio 3 e 4 de maturação sexual. As medidas antropométricas da perna e coxa, assim como o cálculo do volume da coxa, foram obtidos por meio das medidas de circunferência e comprimento, seguindo protocolo proposto por Sady et al. (1982). O pico de potência anaeróbia foi mensurado mediante teste de potência anaeróbia de Wingate. Foi utilizada a estatística descritiva (média e desvio padrão) para a caracterização da amostra. Para verificar o grau de correlação entre o volume da coxa e o pico de potência anaeróbia foi utilizado o teste de correlação binária de Pearson. Para observar a correlação entre o pico de potência anaeróbia e as variáveis antropométricas, foi feita a análise de regressão linear múltipla. Verificaram-se correlações significativas entre as variáveis antropométricas e a potência anaeróbia, havendo forte correlação da massa magra e o volume da coxa com a potência relativa e absoluta. Por meio da análise de regressão, a massa magra corporal determinou 83% da potência anaeróbia nestes adolescentes. Nossos resultados indicam que a potência anaeróbia está correlacionada com as medidas antropométricas, e a massa magra foi determinante no desempenho anaeróbio. As medidas dos comprimentos corporais e sua associação com as demais variáveis são relevantes para futuros estudos a ponto de predizer novos modelos preditivos para determinação do desempenho anaeróbio.

Abstract:

O "Rugby" é um esporte bastante popular internacionalmente e em franca ascensão no Brasil. É caracterizado pela existência de duas posições táticas básicas ("forwards" e "backs"), cujos atletas apresentam demandas funcionais e características físicas distintas. Embora a literatura internacional apresente um número interessante de referências acerca do perfil antropométrico e fisiológico destes atletas, pouca atenção tem sido despendida aos atletas brasileiros. Assim, este trabalho teve como objetivo verificar o desempenho de 20 jogadores amadores de "Rugby" submetidos à ergoespirometria, teste de Wingate e Dinamometria isocinética bem como a comparação entre "backs" (n = 10) e "forwards" (n = 10) para verificar possíveis diferenças entre as posições táticas. Para determinação dos valores de VO2 e VCO2 foi utilizado um analisador de gases computadorizado (CPX-D; MedGraphics Cardiorespiratory Diagnostic Systems) para variáveis de força um dinamômetro isocinético Cybex Norm (Lumex & Co., Ronkonkoma, USA) e para comparações de composição corporal foi aplicada a técnica de cinco componentes da ISAK. A comparação entre os dados foi verificada por meio do teste t de Student para amostras independentes, sendo que para todas as variáveis foi adotado um índice de significância de p < 0,05. Os nossos resultados mostram uma diferença significativa entre "backs" e "forwards' nas variáveis VO2max (47,8 ± 4,5 e 38,8 ± 5,5 ml.kg-1.min-1) - 2º limiar ventilatório (38,3 ± 3,0 e 31,6 ± 4,2 ml.kg-1.min-1) - potência média (7,5 ±0,6 e 6,3 ±1,1 W.kg-1) e trabalho total (225,7 ± 18,4 e 187,9 ± 31,7 J.kg-1) - massa corporal (78,5 ± 9,5 e 101,6 ± 12,6 kg) Massa Adiposa (24,7 ± 3,2 e 29,7 ± 4,6%) Massa Muscular (48,7 ± 4,2 e 44,5 ± 3,4%) respectivamente (p < 0,05). Sendo assim, evidenciamos a existência de diferenças significativas em algumas das variáveis medidas entre atletas de "Rugby' conforme sua função no jogo. Essa evidência mostra que mesmo os atletas sendo de nível amador, as características fisiológicas, antropométricas e mecânicas são semelhantes quando comparadas aos jogadores de nível profissional.

Abstract:

Background/Aim. The Wingate anaerobic test is a valid and reliable method of measuring anaerobic capacity. The aim of this study was to determine whether other modified test can be used instead of the Wingate test. Methods. A group of 30 sedentary young men were first tested with a cycle ergometer (classic Wingate test), and then with a dynamometer during 30 s of 'all out' leg extension exercise (modified Wingate test; WAnTe) in order to test anaerobic capacity. Subsequent correlations between these tests were made. Results. Peak power, mean power on cycling ergometer in absolute and relative values were 463 ? 105 W, 316.7 ? 63.8 W, 5.68 ? 1.17 W/kg, 3.68 ? 0.78 W/kg, respectively. On a dynamometer absolute and relative values of maximal and mean load in kg and power in Watts were 136.54 ? 21.3 kg, 1.67 ? 0.26; 128.65 ? 19.93 kg, 1.57 ? 0.24 kg, 657 ? 125.87 W, and 8 ? 1.54 W/kg, respectively. There was no correlation between 5 s intervals of the classic Wingate test and WAnTe during the first, fourth and fifth intervals, but in the second (r = 0.49, p < 0.05), third (r = 0.38, p < 0.05) and last 5 s intervals (r = 0.39, p < 0.05), and also in peak power and mean power (r = 0.42, p < 0.05 and r = 0.45, p < 0.05 respectively), a significant positive correlation was detected. Conclusion. A modified Wingate test of leg extension on a dynamometer in sedentary young men shows a correlation with the classic Wingate test only in parameters of peak power, and mean power and the second, the third and the last 5 s intervals. Because of that it should only be used for orientation, whereas for precise measurements of anaerobic capacity the classic Wingate test should be used.

Abstract:

The 30-s all-out Wingate test has been used in athletes of all sport specialties to measure the capacity for short duration, high power output while cycling. The aim of this study was to establish differences in measuring anaerobic capacity between the classic Wingate test on a cycling ergometer and the modified Wingate test on a rowing ergometer in rowers. A group of 20 rowers was tested by both the cycle and rowing ergometers during 30s of maximum power to test anaerobic capacity and to make correlation between these tests. The parameters measured were the peak power and mean power. The peak power on the cycling ergometer was 475?75.1W and 522.4?81W (p<0.05) on the rowing ergometer. The mean power on the cycling ergometer and the rowing ergometer was 344.4?51.1W and 473.7W?67.2, (p<0.05) respectively. The maximum values were achieved at the same time on both ergometers, but remained on the higher level till the end of the test on the rowing ergometer. By correlating the anaerobic parameters of the classic Wingate test and a modified Wingate test on the rowing ergometer a significant positive correlation was detected in the peak power (r=0.63, p<0.05) as well as in the mean power (r=0.65, p<0.05). The results show that the rowers achieved better results of the anaerobic parameters on the rowing ergometer compared to the cycling ergometer due to a better mechanical efficiency. It is concluded that the modified Wingate test on the rowing ergometer can be used in rowers for testing their anaerobic capacity as a sport specific test ergometer since it provides more precise results.

Abstract:

Purpose: To evaluate the effects of a 6-week taekwondo-specific high-intensity interval training (HIIT) in simulated normobaric hypoxia on physical fitness and performance in taekwondoists. Methods: Eighteen male and female black-belt taekwondoists trained twice a week for 6 weeks in normoxia or in hypoxia (FiO2 = 0.143 O2). The HIIT was composed of specific taekwondo movements and simulated fights. Body composition analyses and a frequency speed of kick test during 10 seconds (FSKT10s) and 5 × 10 seconds (FSKTmult), countermovement jump (CMJ) test, Wingate test, and an incremental treadmill test were performed before and after training. Blood lactate concentrations were measured after the FSKTmult and Wingate tests, and a fatigue index during the tests was calculated. Results: A training effect was found for FSKT10s (+35%, P < .001), FSKTmult (+32%, P < .001), and fatigue index (−48%, P = .002). A training effect was found for CMJ height (+5%, P = .003) during the CMJ test. After training, CMJ height increased in hypoxia only (+7%, P = .005). No effect was found for the parameters measured during Wingate test. For the incremental treadmill test, a training effect was found for peak oxygen consumption (P = .002), the latter being 10% lower after than before training in normoxia only (P = .002). Conclusions: In black-belt taekwondoists, hypoxic HIIT twice a week for 6 weeks provides tiny additional gains on key performance parameters compared with normoxic HIIT. Whether the trivial effects reported here might be of physiological relevance to improve performance remains debatable and should be tested individually.

Abstract:

We tested seven physical education students whether 30-s sprint anaerobic exercise (Wingate test) would result in oxidative stress (evaluated by lipid radical levels) sufficient to alter plasma non-enzymatic antioxidant status (plasma uric acid, ascorbic acid, α-tocopherol, β-carotene). This study demonstrates that 1) Wingate test increases plasma uric and ascorbic acid concentrations (p < .05), and decreases plasma α-tocopherol and β-carotene levels (p < .05); 2) lipid radical levels at rest and sprint performance are negatively correlated with resting plasma uric acid and α-tocopherol concentrations (p < .05). In conclusion, this study 1) demonstrates that a 30-s sprint anaerobic exercise is associated with acute changes in plasma non-enzymatic antioxidant status, 2) indicates that the subjects with largest leg peak power are those who exhibit the lowest plasma antioxidant status at rest (uric acid and α-tocopherol), 3) and suggests that antioxidant intake by maintaining plasma antioxidant concentration at rest in the normal range might protect athletes against oxidative stress induced by exercise. Key words: ascorbic acid, α-tocopherol, β-carotene, uric acid, oxidative stress

Abstract:

The effects of a novel winglet-cavity tip on the flow field and aerodynamic performance of a turbine blade with tip clearance have been investigated in a low-speed wind tunnel. A calibrated five-hole probe is used for the measurement of three-dimensional flows downstream of the cascade. The method of oil-flow visualization is used to show the endwall flow field structure. The distribution of endwall static pressure is measured particularly by using the special moveable endwall. The downstream results show that, compared with the flat tip and cavity tip, the winglet-cavity tip reduces aerodynamic loss in the region of tip leakage vortex and passage vortex effectively and gives a 8.5% reduction of total pressure losses at a tip clearance of τ/ H = 1.0%. Meanwhile, a more uniform flow angle is obtained with the winglet-cavity tip. Thus, the winglet-cavity tip provides better aerodynamic performance. It was found that more endwall flow enters the cavity from the front of suction side gap, combines with the flow entering the tip from the pressure side, and then separates upon the cavity. This reduces the loss of passage vortex. The endwall static pressure indicates that the winglet-cavity tip reduces the driving pressure difference and weakens the tip leakage flow. With the tip clearance increasing, the leakage flow is significantly enhanced. This strengthens the interaction between the tip leakage vortex and the passage vortex. With respect to the flat tip and cavity tip, the winglet-cavity tip obtains the lowest total pressure loss at all tested tip clearances.

Full text

Abstract:

The low-frequency in-plane thickness noise generating from the displacement of air by rotating blades has an important influence on helicopter detection. An on-blade control technique to reduce thickness noise is developed in this paper based on the principle of sound field cancellation. Following the theoretical study on the mechanism of thickness noise reduction using in-plane unsteady force, a 2-m diameter rotor with an active trailing-edge winglet are designed and tested in a fully anechoic chamber. The winglet installed on the outboard blade is used to generate the unsteady force and anti-noise to counteract the thickness noise. The results demonstrate that effective reduction of thickness noise up to 3 dB is achieved in the front of the rotor when the winglet is under the one-harmonic control with 3 ° of deflection angle. Moreover, the experiments of frequency, amplitude, and phase scanning are carried out to study the parametric effects of winglet motions on noise reduction. The ability of noise reduction is proportional to the deflection amplitude of the winglet in each frequency. The control phase determines where noise can be reduced. There is an optimal phase angle at each frequency to minimize the noise at the observations, and it varies with different frequencies. The relationship among observation position, control phase, and frequency is derived, and the approximate expression of the optimal phase is presented.

Abstract The purpose was to determine the magnitude of aerobic and anaerobic performance factors among elite male football players in different team positions. Thirty-nine players from the highest Swedish division classified as defenders (n=18), midfield players (n=12) or attackers (n=9) participated. Their mean (± sd) age, height and body mass (bm) were 24.4 (±4.7) years, 1.80 (±5.9)m and 79 (±7.6)kg, respectively. Running economy (RE) and anaerobic threshold (AT) was determined at 10, 12, 14, and 16km/h followed by tests of maximal oxygen uptake (VO2max). Maximal strength (1RM) and average power output (AP) was performed in squat lifting. Squat jump (SJ), counter-movement jump with free arm swing (CMJa), 45m maximal sprint and the Wingate test was performed. Average VO2max for the whole population (WP) was 57.0mL O2•kg−1min−1. The average AT occurred at about 84% of VO2max. 1RM per kg bm0.67 was 11.9±1.3kg. Average squat power in the whole population at 40% 1RM was 70±9.5W per kg bm0.67. SJ and CMJa were 38.6±3.8cm and 48.9±4.4cm, respectively. The average sprint time (45m) was 5.78± 0.16s. The AP in the Wingate test was 10.6±0.9W•kg−1. The average maximal oxygen uptake among players in the highest Swedish division was lower compared to international elite players but the Swedish players were better off concerning the anaerobic threshold and in the anaerobic tests. No significant differences were revealed between defenders, midfielders or attackers concerning the tested parameters presented above.

Abstract:

We intended to determine the concurrent validity of a taekwondo specific anaerobic test (TSAT) to assess anaerobic fitness in taekwondo athletes. Seventeen elite male subjects (17.59 ± 4.34 years of age; 1.72 m ± .07 m in height; 61.3 kg ± 8.7 kg in weight and 15.6% ± 8.5% in body fat) performed a TSAT, which consisted of kicking a punching bag for 30 seconds. The standard test was the Wingate Anaerobic Test. Two trials were made for both tests and the agreement between both was tested. The variables analysed and compared were: peak power; relative peak power; mean anaerobic power; relative mean anaerobic power; fatigue index and anaerobic capacity. The number of kicks performed in the TSAT protocol and the maximum height of the counter movement jump (CMJ) were also registered. Trial I and II had significant ICC results in all variables (P = .000) ranged between 0.56 and 0.97. Both protocols were significantly correlated (r = 0.55 to 0.88; P = .000 to .05). CMJ strongly correlated with the number of techniques (r=0.59; P = .013) and the mean power (r = 0.56; P = .019) of the TSAT. The variables between the two methods correlate and are consistent, except for the anaerobic capacity that although correlated, is not consistent with constant bias, P = 0.001; CI]-705.1;-370.2[. TSAT has a level of agreement with the Wingate, and assigns specificity in the evaluation of these variables.

Abstract:

Introduction. Anaerobic power is an important factor determining the physical performance in various kinds of sports. Therefore, the aim of this paper is to present women’s anaerobic power in soccer players (SP), table tennis players (TT) and weightlifters (WL). Methods. This study involved 3 groups of professional athletes women: 15 SP, 12 TT and 12 WL, which are of a similar age and sports’ level. Anaerobic power in all athletes was recorded during 30-second Wingate test, with resistance set at 0,075 kp x kg (–1). Results. Relatively expressed total external work (TW), maximal power output (Pmax) and the fatigue index (FI) of tested athletes were similar. Mean power (Pmean) was different among the treatment groups (F=12,445; p<0,001), while in TT group these values were significantly lower than in SP and in WL athletes. Somatic variables in 3 groups of tested athletes have not changed. Conclusions. Type of practiced sport has an impact on the size of anaerobic power. Several years of sports training in table tennis has not changed the anaerobic potential of surveyed women while specific training in soccer and weightlifting increased only Pmean.

Abstract:

The purpose of this investigation was to determine the effect of systematic changes in hip position/configuration on cycling peak anaerobic power (AP) and anaerobic capacity (AC). Fourteen male recreational cyclists (ages 21-32 yrs) were tested in four hip positions (25, 50, 75, and 100°), as defined by the angle formed by the seat tube and a vertical line. Rotating the seat to maintain a backrest perpendicular to the ground induced a systematic decrease in hip angle from the 25 to the 100° position. The Wingate anaerobic cycling test was used on a Monark cycle ergometer with a resistance of 85 gm/kg of the subject’s body mass. Repeated-measures MANOVAs and post hoc tests revealed that AP and AC in the 75° hip position were significantly greater than in the 25 or 100° position and that a second-order function best describes the trend in AP and AC with changes in hip position.

Abstract:

Dynamic postural control is challenged during many actions in sport such as when landing or cutting. A decrease of dynamic postural control is one possible risk factor for non-contact injuries. Moreover, these injuries mainly occur under loading conditions. Hence, to assess an athlete’s injury risk properly, it is essential to know how dynamic postural control is influenced by physical load. Therefore, the study’s objective was to examine the influence of maximal anaerobic load on dynamic postural control. Sixty-four sport students (32 males and 32 females, age: 24.11 ± 2.42, height: 175.53 ± 8.17 cm, weight: 67.16 ± 10.08 kg) were tested with the Y-Balance Test before and after a Wingate Anaerobic Test on a bicycle ergometer. In both legs, reach distances (anterior) and composite scores were statistically significantly reduced immediately after the loading protocol. The values almost returned to pre-load levels in about 20 min post-load. Overall, findings indicate an acute negative effect of load on dynamic postural control and a higher potential injury risk during a period of about 20 min post-load. To assess an athlete’s sports-specific injury risk, we recommend testing dynamic postural control under loaded conditions.

Abstract:

The effect of blade number on small Horizontal Axis Wind Turbine (HAWT) has been studied experimentally and numerically in this research. The turbine blade is made of a flat metal sheet and the tip was formed to shape a winglet. The 5-blades turbine was tested inside a wind tunnel for performance investigation at different wind speeds. The experiment was conducted under various wind speed, i.e. 3.5 m/s, 3.9 m/s, 4.3 m/s, 4.6 m/s dan 5 m/s. Furthermore, three wind turbines geometry with different blade number (3, 4, and 5 blades) were built for numerical study purpose by using Ansys Fluent and the results were compared to the experimental one. The results show that the blade number does increase the wind turbine torque and there is also more power generated from the turbine with more blade numbers since torque is related to pressure. Moreover, the winglet helps the blade to retain the flow and increases the pressure on the blade surface. However, the experimental measurements obtained were smaller than the numerical predictions about 50% on the average since more unidentified losses existed and not accounted for the calculation.

Comparison of a New Test For Agility and Skill in Soccer With Other Agility TestsThe purpose of this study was both to develop a novel test to measure run, shuttle run and directional change agility, and soccer shots on goal with decision making and to compare it with other agility tests. Multiple comparisons and assessments were conducted, including test-retest, Illinois, Zig-Zag, 30 m, Bosco, T-drill agility, and Wingate peak power tests. A total of 113 Turkish amateur and professional soccer players and tertiary-level students participated in the study. Test-retest and inter-tester reliability testing measures were conducted with athletes. The correlation coefficient of the new test was .88, with no significant difference (p> 0.01> 0.01) between the test results obtained in the first and second test sessions. The results of an analysis of variance revealed a significant (p < 0.01) difference between the T-drill agility and power test results for soccer players. The new agility and skill test is an acceptable and reliable test when considering test-retest reliability and inter-rater reliability. The findings in this study suggest that the novel soccer-specific agility and shooting test can be utilized in the testing and identification of soccer players' talents.

Abstract:

Searching for potential relations between changes in 25(OH)D concentration and in physical fitness is an interesting scientific topic. Thus, the main purpose of this study was to investigate the changes in serum concentrations of 25(OH)D in young football players in conjunction with indicators determining bone resorption and physical fitness. A total of 35 young soccer players were tested during the autumn competition period. Biochemical analysis of blood, aerobic capacity, running speed and power tests (Wingate test, squat jump, counter movement jump) were carried out at the beginning and at the end of the competition period. Significant decrements in concentration of 25(OH)D from 33.9 ± 5.87 to 23.7 ± 5.58 ng/mL were noted after the analyzed competition period. There were no significant changes in aerobic capacity along the competition period. Significant improvements were observed in 10 m sprint, 30 m sprint (p < 0.001), maximal power (p = 0.011) and total work capacity (p = 0.024). We found that the effect of changes in the players’ physical fitness does not occur in relation to 25 OH(D) concentration but occurs when these changes are analyzed as a function of the duration of the observation period. Changes in physical fitness of soccer players are determined by other factors then 25(OH)D concentration.

Abstract:

Objectives: Upper limb explosive power is an important motor quality for sporting performance and indicates use of anaerobic energy systems. The Wingate Anaerobic Test (WAnT) has been considered to be a valid and reliable tool for the assessment of anaerobic power and functional performance of elite athletes. However, it is expensive and a lab based test and requires skilled manpower. The seated medicine ball throw test (SMBT) is inexpensive, easy to assess and since equipment required is minimal, it can be easily used as a field test. Hence, the purpose of the study was to determine if the SMBT method could be used as an alternative for WAnT test so that a reliable and inexpensive test is available for athlete monitoring and talent identification screening. Materials and Methods: Male elite athletes aged 18–30 years (n = 100), who were involved in national level competition of three sports discipline, namely, Boxing (n = 34), Wrestling Greco-Roman (GR) (n = 36), and Wrestling Freestyle (FS) (n = 30), were tested on crank-arm ergometer for WAnT and SMBT to measure an peak power or explosive power for the upper body. Results: SMBT test results were significantly positively correlated with upper body peak power measured by WAnT in all sportsmen (r = 0.55, P = 0.0002). One sample t-test results showed that the mean difference between SMBT and peak power is close to zero among Boxers (P = 0.13) and FS wrestlers (P = 0.89) and GR Wrestlers (P = 0.49). Overall, 97% pairs of SMBT and peak power were within the limits of agreement among all sportsmen, showing that results using both the tests were agreeable. Conclusion: This study suggests that SMBT tests could be used as an alternative field test to measure anaerobic power in Wrestlers, Boxers, and sports where the involvement of upper body muscles take place predominantly. In addition, the SMBT protocol used in this study provides an easy way for the coaches to assess the athletes on the field during talent identification and also to evaluate their training program.

We tested 25 (15 male, 10 female) Indian judokas for absolute and relative strength (back-squat and bench-press one-repetition maximum (1RM) as well as isometric handgrip), aerobic (RAMP test) and lower-body anaerobic power (Wingate 6-s sprint and countermovement jump), change-of-direction (5-0-5 test) and speed (30 m sprint). Athletes were grouped according to national-level competition placing (gold-medal winners (GM; n = 8), all medal winners (MW; n = 13), non-medallists (NM; n = 12), and NM plus silver and bronze; all others (AO; n = 17)). Stepwise discriminant function analysis determined characteristics likely to predict successful performance. Independent t-tests and effect size (Hedge’s g) analyses were performed between groups. GM demonstrated greater lower-body absolute (20.0%; g = 0.87, p = 0.046) and relative 1RM strength (21.0%; g = 0.87, p = 0.047), and greater lower-body absolute (25.4%; g=1.32, p=0.004) and relative (27.3%; g = 1.27, p = 0.005) anaerobic power compared to AO. Furthermore, anaerobic power can correctly predict 76.5% and 62.5% of AO and GM athletes, respectively. No differences were observed between MW and NM groups. The results suggest the importance of lower-body strength and power for junior national-level judokas and provides information for professionals working with these athletes.

Abstract:

Parra et al. ( Acta Physiol. Scand 169: 157–165, 2000) showed that 2 wk of daily sprint interval training (SIT) increased citrate synthase (CS) maximal activity but did not change “anaerobic” work capacity, possibly because of chronic fatigue induced by daily training. The effect of fewer SIT sessions on muscle oxidative potential is unknown, and aside from changes in peak oxygen uptake (V̇o2 peak), no study has examined the effect of SIT on “aerobic” exercise capacity. We tested the hypothesis that six sessions of SIT, performed over 2 wk with 1–2 days rest between sessions to promote recovery, would increase CS maximal activity and endurance capacity during cycling at ∼80% V̇o2 peak. Eight recreationally active subjects [age = 22 ± 1 yr; V̇o2 peak = 45 ± 3 ml·kg−1·min−1 (mean ± SE)] were studied before and 3 days after SIT. Each training session consisted of four to seven “all-out” 30-s Wingate tests with 4 min of recovery. After SIT, CS maximal activity increased by 38% (5.5 ± 1.0 vs. 4.0 ± 0.7 mmol·kg protein−1·h−1) and resting muscle glycogen content increased by 26% (614 ± 39 vs. 489 ± 57 mmol/kg dry wt) (both P < 0.05). Most strikingly, cycle endurance capacity increased by 100% after SIT (51 ± 11 vs. 26 ± 5 min; P < 0.05), despite no change in V̇o2 peak. The coefficient of variation for the cycle test was 12.0%, and a control group ( n = 8) showed no change in performance when tested ∼2 wk apart without SIT. We conclude that short sprint interval training (∼15 min of intense exercise over 2 wk) increased muscle oxidative potential and doubled endurance capacity during intense aerobic cycling in recreationally active individuals.

Abstract:

This study examined the effects of military field operations (MFO) under different environmental conditions on anaerobic performance. US Marines were tested in the field under the following conditions: 1) noncold environment (NC; n = 30, 10–32 degrees C) and 2) cold environment (CO; n = 32, -2 to -22 degrees C). Subjects performed 30-s Wingate tests (WIN) pre- and immediately post-MFO to assess anaerobic performance. The MFO consisted of approximately 4.5 days of combat training maneuvers while carrying field equipment (packs and weapon, approximately 25 kg). WIN measures obtained were absolute and relative mean power (MP), 5-s peak power (PP), and fatigue index (% decline). Significant main effects (P less than 0.01) were observed for time (pre-post MFO). Reductions occurred in absolute MP [651.8 +/- 30.3 to 616.4 +/- 28.5 (SE) W] and PP (897.8 +/- 41.6 to 857.0 +/- 39.1 W); however, no effect on fatigue index was seen. Significant interaction effects (P less than 0.05) were observed in relative measures. Reductions (pre-post) in MP (NC = 8.64 +/- 0.16 to 8.37 +/- 0.14 W/kg; CO = 8.91 +/- 0.26 to 8.04 +/- 0.15 W/kg) and PP (NC = 11.80 +/- 0.24 to 11.61 +/- 0.33 W/kg; CO = 12.23 +/- 0.35 to 11.20 +/- 0.19 W/kg) were greater under CO than NC conditions. These changes were found despite significant (P less than 0.05) but comparable pre-post weight reductions in both CO and NC conditions.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract:

Caffeine’s ergogenic effects on exercise performance are generally explained by its ability to bind to adenosine receptors. ADORA2A is the gene that encodes A2A subtypes of adenosine receptors. It has been suggested that ADORA2A gene polymorphisms may be responsible for the inter-individual variations in the effects of caffeine on exercise performance. In the only study that explored the influence of variation in ADORA2A—in this case, a common polymorphism (rs5751876)—on the ergogenic effects of caffeine on exercise performance, C allele carriers were identified as “non-responders” to caffeine. To explore if C allele carriers are true “non-responders” to the ergogenic effects of caffeine, in this randomized, double-blind study, we examined the acute effects of caffeine ingestion among a sample consisting exclusively of ADORA2A C allele carriers. Twenty resistance-trained men identified as ADORA2A C allele carriers (CC/CT genotype) were tested on two occasions, following the ingestion of caffeine (3 mg/kg) and a placebo. Exercise performance was evaluated with movement velocity, power output, and muscle endurance during the bench press exercise, countermovement jump height, and power output during a Wingate test. Out of the 25 analyzed variables, caffeine was ergogenic in 21 (effect size range: 0.14 to 0.96). In conclusion, ADORA2A (rs5751876) C allele carriers exhibited ergogenic responses to caffeine ingestion, with the magnitude of improvements similar to what was previously reported in the literature among samples that were not genotype-specific. Therefore, individuals with the CT/CC genotype may still consider supplementing with caffeine for acute improvements in performance.

Abstract:

The aim of this study was to determine the effects of different musical rhythms on taekwondo athletes. The variance in athletes’ anaerobic abilities performed under slow and fast musical rhythms was tested in the study presented. Previous studies have demonstrated how music may cause physiological responses before, during, or after different types of exercises. The aim of this study was to identify the effect of music played in two different rhythms (slow 80 b/m, and fast 200 b/m) during anaerobic exercises by measuring four specific physiological variables: heart rate (HR), blood pressure (BP), blood lactate (BL), and rate of perceived exertion (RPE). Additionally, the peak power of each athlete was assessed. Ten black-belt taekwondo male athletes (average age 20.38±1.51) performed for 30 seconds at their maximum anaerobic power on a Monarch Ergonomic that was connected to the Wingate test. The RPE indicated significant differences with a probability value of 0.014 when measured two minutes after the testing. Measurements of heart rate, blood lactate, and diastolic blood pressure after exposure to slow and fast rhythms did not show significant differences. While it has been shown in previous research that the human body tends to synchronize with rhythmic elements of music, this only holds true for exposure to specific rhythms after a longer period of time. The study conducted was based on exposure to different rhythms for only 30 seconds, which may be why these variables did not differ significantly. Yet, results for systolic blood pressure proved significantly different for fast and slow musical rhythms with a probability value of 0.0004.

Abstract:

Abstract The aim of this study was to evaluate relationships between anaerobic performance, field tests, game performance and anthropometric variables of sitting volleyball players. Twenty elite Polish sitting volleyball players were tested using the 30 s Wingate Anaerobic Test for arm crank ergometer and participated in six physical field tests. Heights in position to block and to spike, as well as arm reach were measured. Players were observed during the game on the court in terms of effectiveness of the serve, block, attack, receive and defense. Pearson analysis and the Spearman's rank correlation coefficient were used. The strongest correlations were found between the chest pass test and mean power and peak power (r=.846; p=.001 and r=.708; p=.0005, respectively), and also between the T-test and peak power (r= −.718; p=.001). Mean power correlated with the 3 m test (r= −.540; p=.014), the 5 m test (r= −.592; p=.006), and the T-test (r= −.582; p=.007). Peak power correlated with the 3 m test (r= −.632; p=.003), the 5 m test (r= −.613; p=.004), speed & agility (r= −.552; p=.012) and speed & endurance (r=−.546; p=.013). Significant correlations were observed between anthropometric parameters and anaerobic performance variables (p≤.001), and also between anthropometric parameters and field tests (p≤.05). Game performance and physical fitness of sitting volleyball players depended on their anthropometric variables: reach of arms, the position to block and to spike. The chest pass test could be used as a non-laboratory field test of anaerobic performance of sitting volleyball players.

Abstract:

Anaerobic power and capacity are considered determinants of performance and are usually assessed in athletes as a part of their physical capacities’ evaluation along the season. For that purpose, many field tests have been created. The main objective of this study was to analyze the agreement between four field tests and a laboratory test. Nineteen CrossFit® (CF) athletes were recruited for this study (28.63 ± 6.62 years) who had been practicing CF for at least one year. Tests performed were: (1) Anaerobic Squat Test at 60% of bodyweight (AST60); (2) Anaerobic Squat Test at 70% of bodyweight (AST70); (3) Repeated Jump Test (RJT); (4) Assault Bike Test (ABT); and (5) Wingate Anaerobic Test on a cycle ergometer (WG). All tests consisted of 30 s of max effort. The differences among methods were tested using a repeated-measures analysis of variance (ANOVA) and effect size. Agreement between methods was performed using Bland–Altman analysis. Analysis of agreement showed systematic bias in all field test PP values, which varied between −110.05 (AST60PP—WGPP) and 463.58 (ABTPP—WGPP), and a significant proportional error in ABTPP by rank correlation (p < 0.001). Repeated-measures ANOVA showed significant differences among PP values (F(1.76,31.59) = 130.61, p =< 0.001). In conclusion, since to our knowledge, this is the first study to analyze the agreement between various methods to estimate anaerobic power in CF athletes. Apart from ABT, all tests showed good agreement and can be used interchangeably in CF athletes. Our results suggest that AST and RJT are good alternatives for measuring the anaerobic power in CF athletes when access to a laboratory is not possible.

Abstract:

Three to 5 cycling tests to exhaustion allow prediction of time to exhaustion (TTE) at power output based on calculation of critical power (CP). We aimed to determine the accuracy of CP predictions of TTE at power outputs habitually endured by cyclists. Fourteen endurance-trained male cyclists underwent 4 randomized cycle-ergometer TTE tests at power outputs eliciting (i) mean Wingate anaerobic test (WAnTmean), (ii) maximal oxygen consumption, (iii) respiratory compensation threshold (VT2), and (iv) maximal lactate steady state (MLSS). Tests were conducted in duplicate with coefficient of variation of 5%–9%. Power outputs were 710 ± 63 W for WAnTmean, 366 ± 26 W for maximal oxygen consumption, 302 ± 31 W for VT2 and 247 ± 20 W for MLSS. Corresponding TTE were 00:29 ± 00:06, 03:23 ± 00:45, 11:29 ± 05:07, and 76:05 ± 13:53 min:s, respectively. Power output associated with CP was only 2% lower than MLSS (242 ± 19 vs. 247 ± 20 W; P < 0.001). The CP predictions overestimated TTE at WAnTmean (00:24 ± 00:10 mm:ss) and MLSS (04:41 ± 11:47 min:s), underestimated TTE at VT2 (–04:18 ± 03:20 mm:ss; P < 0.05), and correctly predicted TTE at maximal oxygen consumption. In summary, CP accurately predicts MLSS power output and TTE at maximal oxygen consumption. However, it should not be used to estimate time to exhaustion in trained cyclists at higher or lower power outputs (e.g., sprints and 40-km time trials). Novelty CP calculation enables to predict TTE at any cycling power output. We tested those predictions against measured TTE in a wide range of cycling power outputs. CP appropriately predicted TTE at maximal oxygen consumption intensity but err at higher and lower cycling power outputs.

Recovery processes after repeated supramaximal exercise at the altitude of 4,350 m. J. Appl. Physiol. 82(6): 1897–1904, 1997.—We tested the hypothesis that prolonged exposure to high altitude would impair the restoration of muscle power during repeated sprints. Seven subjects performed two 20-s Wingate tests (WT1 and WT2) separated by 5 min of recovery, at sea level (N) and after 5–6 days at 4,350 m (H). Mean power output (MPO) and O2 deficit were measured during WT. O2 uptake (V˙o 2) and ventilation (V˙e) were measured continuously. Blood velocity in the femoral artery (FBV) was recorded by Doppler ultrasound during recovery. Arterialized blood pH and concentrations of bicarbonate ([[Formula: see text]]), venous plasma lactate ([La−]), norepinephrine ([NE]), and epinephrine ([Epi]) were measured before and after WT1 and WT2. MPO decreased between WT1 and WT2 by 6.9% in N ( P < 0.05) and by 10.7% in H ( P < 0.01). H did not further decrease MPO. O2 deficit decreased between WT1 and WT2 in H only ( P < 0.01). PeakV˙o 2 after WT was reduced by 30–40% in H ( P < 0.01), but excess postexercise O2 consumption was not significantly lowered in H. During recovery in H compared with N, V˙e, exercise-induced acidosis, and [NE] were higher, [Epi] tended to be higher, [La−] was not altered, and [[Formula: see text]] and FBV were lower. The similar [La−] accumulation was associated with a higher exercise-induced acidosis and a larger increase in [NE] in H. We concluded from this study that prolonged exposure to high altitude did not significantly impair the restoration of muscle power during repeated sprints, despite a limitation of aerobic processes during early recovery.

Abstract:

Currently, it is well accepted that physical exercise-induced oxidative stress may damage biological structures and impair cellular functions. However, it is still unclear which type of exercise results in the greatest oxidative stress responses among a healthy untrained population. The aim of the present study was to compare the acute oxidative stress response (i.e., 0 to 20 min) following different types of exercise (anaerobic, aerobic, and combined). Ten healthy, untrained males (19.5 ± 1.7 years) performed three randomized exercise bouts: anaerobic (30 s Wingate test), aerobic (30 min at 60% maximal aerobic power (MAP)) or combined (anaerobic and aerobic). Venous blood samples were collected before, as well as at 0 (P0), 5 (P5), 10 (P10), and 20 (P20) min after each session. Rates of malondialdehyde (MDA) and antioxidant activities (i.e., glutathione peroxidase (GPX), superoxide dismutase (SOD), glutathione reductase (GR), α-tocopherol, and total antioxidant status (TAS)) were assessed. Independent of exercise type, plasma MDA, GPX, SOD, and GR contents increased above baseline, whereas plasma α-tocopherol decreased under baseline after the test sessions (p < 0.05). Aerobic and anaerobic exercises generated faster responses (at P0) when compared to the combined exercise (P5 to P10) for the majority of the tested parameters. Plasma TAS content only increased following the aerobic exercise at P10 (p = 0.03). Five to twenty-minutes post exercise, the highest MDA response was registered in the aerobic condition, and the highest GPX and SOD responses were recorded in the anaerobic (at P5) and aerobic (at P20) conditions (p < 0.05). In conclusion, aerobic, anaerobic, or combined exercises have the potential to acutely increase oxidative stress and antioxidant activities, but with different responses magnitude. These findings confirm that oxidative stress response seems to be dependent on the intensity and the duration of the physical exercise and may help in understanding how varying exercise bouts influence the degree of oxidative stress among healthy untrained young adults.

Abstract:

Parasitic plants extract resources from host vascular tissues but their responses to environmental fluctuation experienced by the host are poorly studied. Three frequently-cited hypotheses for effects of environmental stress on plant resistance to herbivores predict decreased, increased, or fluctuation in herbivore performance in response to drought stress. We tested which hypothesis best accounts for how drought stress applied to a perennial herb affects growth of the holoparasite, Cuscuta gronovii Willd. ex Roem. & Schult. (common dodder), an obligate shoot parasite. Verbesina alternifolia (L.) Britton ex Kearney (wingstem) supporting single, young C. gronovii were exposed to continuous, pulsed, or no water stress for 32 days and then dry mass of each parasite was determined. Consistent with the plant vigor hypothesis, C. gronovii grew significantly better on well-watered hosts. Continuous and pulsed drought stress of the host resulted in similar growth reduction relative to no drought stress. In addition to reducing absolute growth of the holoparasite, continuous and pulsed drought stress reduced the growth of the holoparasite relative to host growth. Although functionally similar to insect phloem feeders, growth of holoparasites such as C. gronovii is constrained by source–sink relations. Our results suggest drought stress experienced by a host weakens source strength and reduces uptake by the holoparasite acting as a sink.
