Abstract:
Short-term sprint cycling performance recovery was investigated, with consideration to the Match Sprint. Fifteen strength-trained men (age: 24 ± 6 years; height: 1.81 ± 0.08 m; body mass: 83.4 ± 8.4 kg) were first familiarised with an 18 s sprint. During the baseline trial, blood lactate concentration, tissue saturation index, and oxygen uptake were monitored following a single sprint. In the remaining trials, the recovery duration (45, 90, 135, 180, 360, and 720 s) between two sprints was varied. Peak (PPO) and mean (MPO) power output were computed for each sprint. The recovery percentage of MPO and the recovery time-course of the physiological variables were modelled using one- and two-phase exponential functions. Statistical significance was set a priori at p < 0.05. Effects of sprint number, recovery time, and a sprint number × recovery time interaction were found for both PPO and MPO. Post hoc tests revealed significant differences between sprints at all time-points for both variables. The time constant (τ), 130.6 ± 95.6 s, of the one-phase exponential function (asymptotic amplitude [A0] = 97.4 ± 2.5%), suggested that performance recovery had stabilised within 12 minutes. However, the parameters of the two-phase function indicated that recovery was incomplete (A0 = 87.7 ± 6.4%, A1 = 11.9 ± 5.2%, τ0 = 56.3 ± 33.3 s, τ1 = 458.2 ± 283.3 s). The τ for MPO recovery was not significantly correlated with any of the physiological variables. The reduction in sprint cycling performance throughout the tested time-period could be meaningful for athletes competing in the Match Sprint.

Abstract:
Hydrogen-rich water (HRW) supplementation has been shown to have an antifatigue effect across different modes of exercise. However, its effect on repeated sprint performance is unknown. The aim of this study was to assess the effect of pre-exercise HRW consumption on repeated sprint performance, lactate, and perceptual responses using a repeated sprint protocol. This randomized, double blinded, placebo controlled, crossover study included 16 professional, male soccer players aged 18.8 ± 1.2 years. Athletes performed two indoor tests, particularly 15 × 30 m track sprints interspersed by 20 s of recovery, separated by a 1-week washout period. Sprint time was measured at 15 m and 30 m. Ratings of perceived exertion were assessed immediately after each sprint, and post-exercise blood lactate concentration was measured after the last sprint. There were significantly faster sprint times after HRW consumption compared with placebo at 15 m for the 14th and 15th sprints, representing improvements in time of 3.4% and 2.7%, respectively. Sprint time at 30 m also significantly improved by 1.9% in the HRW group in the last sprint. However, neither lactate concentrations nor ratings of perceived exertion were significantly different between HRW and placebo. Pre-exercise HRW supplementation is associated with an increased ability to reduce fatigue, especially during the later stages of repeated sprint exercise.

Abstract:
Researchers and trainers are continually looking for determinants of soccer talent in the youngest and in the relationship between individual motor features relevant to this kind of sport. There is a fundamental consensus in the opinion that sprinting and jumping share a number of similar characteristics in soccer players. To the authors’ knowledge, the majority of the studies has been conducted in adult and young athletes and there has yet to be an analysis with prepubescent male players. Therefore, the purpose of this study was to investigate the relationships between the standing long jump, the three-hop test and sprint performance in prepubescent male soccer players. Material and methods. This study comprised 112 prepubescent soccer players (aged 12.08±1.79 years; height: 154.35±12.50 cm; body mass 43.69±10.28 kg). They were assessed for a 30-m linear sprint with three split sprint times, standing long jump test and three-hop test. The associations and relationships between horizontal jump performance in three-hop test and standing long jump with 0-5m, 10-m, 20-m and 30-m sprint times were investigated. Results and discussion. Correlations and linear regressions were assessed. There were weak and large associations between sprint and jump measures (r = -0.21 to -0.66; p <0.001). Linear regressions all included standing long jump as a predictor, but not three-hop test. There were no regression equations that would predict sprint times from triple hop distance that were significant. In their study of national team female athletes Agar-Newman and Klimstra, (2015) showed contradictory results. In their athletes, triple hop distance was a better predictor than standing long jump of both initial sprint speed, and maximal sprint speed. Thus, this area requires further research to better understand the mechanisms through which both sprint and jump performances are achieved in prepubescent male soccer players. Conclusion. Overall, the results of our study support the use of 30-m linear sprint and horizontal jump performance tests for prepubescent male soccer players. This research showed that sprint times correlated to horizontal jump performance in three-hop test and standing long jump tests. It showed the utility of the standing long jump test to evaluate lower limb performance between prepubescent male soccer players

Abstract:
Purpose:To investigate the relationships between maximal isometric strength, vertical jump (VJ), sprint speed, and change-of-direction speed (CoDS) in academy netball players and determine whether players who have high performance in isometric strength testing would demonstrate superior performance in VJ, sprint speed, and CoDS measures.Method:Twenty-six young female netball players (age 16.1 ± 1.2 y, height 173.9 ± 5.7 cm, body mass 66.0 ± 7.2 kg) from a regional netball academy performed isometric midthigh pull (IMTP), squat jumps (SJs), countermovement jumps (CMJs), 10-m sprints, and CoDS (505).Results:IMTP measures displayed moderate to strong correlations with sprint and CoDS performance (r = –.41 to –.66). The VJs, which included SJs and CMJs, demonstrated strong correlations with 10-m sprint times (r = –.60 to –.65; P < .01) and CoDS (r = –.60 to –.71; P = .01). Stronger players displayed significantly faster sprint (ES = 1.1–1.2) and CoDS times (ES = 1.2–1.7) and greater VJ height (ES = 0.9–1.0) than weaker players.Conclusion:The results of this study illustrate the importance of developing high levels of lower-body strength to enhance VJ, sprint, and CoDS performance in youth netball players, with stronger athletes demonstrating superior VJ, sprint, and CoDS performances.

Abstract:
The aim of this study was to examine the acute effect of backward running (BwR) during warm-up on a 20-m sprint of boys’ performance, compared to forward running (FwR). Fourteen recreationally active preadolescent boys (aged 12.5 ± 0.5 years) were examined in 3 protocols: warm-up (control condition), warm-up with 3 × 10 m additional BwR sprints and warm-up with 3 × 10 m additional FwR sprints. Participants were evaluated 4 minutes after each protocol on a 20-m sprint and intermediate distances, as well as the rate of perceived exertion (RPE). Sprint speed across 10-20 m was significantly higher for the BwR warm-up compared to the regular warm-up (p < 0.05) and a significantly higher RPE after the BwR and FwR protocols compared to the control condition was recorded (p < 0.05). No significant difference was detected across the distances 0–5, 5–10, 0–10 and 0–20 m. Although adding 3 × 10-m sprints of BwR or FwR after the warm-up did not enhance performance in a 20 m sprint of preadolescent boys, the positive effect of BwR across 10–20 m distance suggests that BwR could be an alternative means for enhancing performance for certain phases of a sprint for this age. However, preadolescent boys’ response to different sprint conditioning exercise stimuli and the optimization of rest time to maximize performance remain to be determined.

Abstract:
Active recovery reduces blood lactate concentration faster than passive recovery and, when the proper intensity is applied, a positive effect on performance is expected. The purpose of the study was to investigate the effect of different intensities of active recovery on performance during repeated sprint swimming. Nine male well-trained swimmers performed 8 repetitions of 25 m sprints (8 × 25 m) interspersed with 45 s intervals, followed by a 50 m sprint test 6 min later. During the 45 s and 6 min interval periods, swimmers either rested passively (PAS) or swam at an intensity corresponding to 50% (ACT50) and 60% (ACT60) of their individual 100 m velocity. Blood lactate was higher during PAS compared with ACT50 and ACT60 trials (p < 0.05), whereas plasma ammonia and glycerol concentration were not different between trials (p > 0.05). Mean performance time for the 8 × 25 m sprints was better in the PAS compared with the ACT50 and ACT60 trials (PAS: 13.10 ± 0.07 vs. ACT50: 13.43 ± 0.10 and ACT60: 13.47 ± 0.10s, p < 0.05). The first 25 m sprint was not different across trials (p > 0.05), but performance decreased after sprint 2 during active recovery trials (ACT50 and ACT60) compared with the passive recovery (PAS) trial (p < 0.05). Performance time for the 50 m sprint performed 6 min after the 8 × 25 m sprints was no different between trials (p > 0.05). These results indicate that active recovery at intensities corresponding to 50% and 60% of the 100 m velocity during repeated swimming sprints decreases performance. Active recovery reduces blood lactate concentration, but does not affect performance on a 50 m sprint when 6 min recovery is provided. Passive recovery is advised during short-interval repeated sprint training in well-trained swimmers.

Abstract:
Since the COVID-19 restrictions, hurling games have been played in four quarters instead of two halves. This study described the decrement in running performance between quarters in elite hurling. GPS (10 Hz) were used to collect data from 48 players over 20 games during 2018–2020 season. Total distance (TD), high-speed running (HSR), high-metabolic-load distance (HMLD), sprint-distance, and number of sprints (N-sprints) between quarters were assessed. Greater TD was covered in Q1 than Q3 (Cohen’s d = 0.26). HSR and HMLD was greater in Q1 than Q2 (d = 0.45 and d = 0.55, respectively), Q3 (d = 0.34 and d = 44, respectively) and Q4 (d = 0.38 and d = 0.48, respectively). Sprint-distance and N-sprints were similar (p > 0.05) across quarters. All positions experienced a drop-off in at least one quarter (d = 0.43–1.46) in all metrics except midfielders’ TD and full-forwards’ HSR and HMLD. Sprint-distance and N-sprints were similar (p > 0.05) in each quarter for all positions. Following Q1, players were able to maintain their running performance. The current results can aid the timing of substitutions especially in positions where temporal decrements were observed.

Abstract:
Purpose:To investigate the influence of torque factor and sprint duration on the effects of caffeine on sprint cycling performance.Methods:Using a counterbalanced, randomized, double-blind, placebo-controlled design, 13 men completed 9 trials. In trial 1, participants completed a series of 6-s sprints at increasing torque factors to determine the torque factor, for each individual, that elicited the highest (Toptimal) peak power output (PPO). The remaining trials involved all combinations of torque factor (0.8 N·m−1·kg−1vsToptimal), sprint duration (10 s vs 30 s), and supplementation (caffeine [5 mg·kg−1] vs placebo).Results:There was a significant effect of torque factor on PPO, with higher values atToptimal(mean difference 168 W; 95% likely range 142–195 W). There was also a significant effect of sprint duration on PPO, with higher values in 10-s sprints (mean difference 52 W; 95% likely range 18–86 W). However, there was no effect of supplementation on PPO (P = .056). Nevertheless, there was a significant torque factor × sprint duration × supplement interaction (P = .036), with post hoc tests revealing that caffeine produced a higher PPO (mean difference 76 W; 95% likely range 19–133 W) when the sprint duration was 10 s and the torque factor wasToptimal.Conclusion:The results of this study show that when torque factor and sprint duration are optimized, to allow participants to express their highest PPO, there is a clear effect of caffeine on sprinting performance.

Abstract:
The ability to repeatedly perform sprints has traditionally been viewed as a key performance measure in team sports, and the relationship between repeated-sprint ability (RSA) and performance has been explored extensively. However, when reviewing the repeated-sprint profile of team-sports match play it appears that the occurrence of repeated-sprint bouts is sparse, indicating that RSA is not as important to performance as commonly believed. Repeated sprints are, however, a potent and time-efficient training strategy, effective in developing acceleration, speed, explosive leg power, aerobic power, and high-intensity-running performance—all of which are crucial to team-sport performance. As such, we propose that repeated-sprint exercise in team sports should be viewed as an independent variable (eg, a means of developing fitness) as opposed to a dependent variable (eg, a means of assessing fitness/performance).

Abstract:
The majority of road cycling races finish with a sprint and as such sprints are a key determinant of success. Surprisingly, the scientific literature on this specific topic is scarce, with limited to few studies describing the characteristics of road cycling sprinters and the demands of road sprinting. Cyclists’ sprinting velocity, which is mostly influenced by power output and aerodynamic drag (CdA) is critical to performance outcomes. However, to date, there is very limited research specifically examining how to maximise road sprint velocity. Thus, the overall objective of the four studies outlined in this thesis was to manipulate CdA, physiology, and coaching cues to improve road sprint cycling velocity and performance. The first study examined the validity of the Velocomp PowerPod, which calculates power output based on opposing/resistive forces experienced. When power output is known (using a direct force power meter), the Velocomp PowerPod is able to calculate a continuous CdA which was the reason why this study was included into this thesis. The research was split in to two separate studies: i) 12 recreational male road cyclists completed a power profile test (5-600 s); and ii) 4 elite male road cyclists completed 13 outdoor cycling training sessions. In both studies, power output of cyclists was continuously measured using both the Velocomp PowerPod and Verve Cycling InfoCrank power meters. The results showed that rolling resistance estimated by the Velocomp PowerPod (0.011 ± 0.0) was higher than what has been previously reported (0.006), which likely occurred due to errors in the subjective selection of road surface type in the device setup. This overestimation of rolling resistance increased the calculated power output, which was significantly greater than the power output measured by the Verve Cycling InfoCrank power meter in both study i and ii (27 to 39% and 16 to 49%, respectively). When rolling resistance was adjusted to previously reported values (0.006), the Velocomp PowerPod power meter was shown to be comparable to the Verve Cycling InfoCrank power meter during a controlled field test (−0.57 to 0.24%) but not dynamic training sessions (8.94 to 33.14%). Consequently, the Velocomp PowerPod power meter was not used in subsequent studies within this thesis. The following two studies examined the effect of a seated, standing, and novel forward standing (lower and further forward head and torso) sprint position on performance. In study 2, eleven recreational male road cyclists rode 250 m at approximately 25, 32, and 40 km·h−1 and in each of the three positions. Riding velocity, power output, wind direction and velocity, road gradient, temperature, relative humidity, and barometric pressure were measured and used to calculate CdA using regression analysis. Sprinting in a forward standing position resulted in a 23% and 26% lower CdA, when compared with a seated and standing position, respectively. Furthermore, in contradiction with previous research no difference in CdA was observed between a seated and standing position. Additionally, despite no significant difference in CdA between the two test days a poor between-day reliability was observed. In study 3, eleven recreational male road cyclists performed a 14 s sprint in the three different sprint positions before and directly after a 10 min high-intensity lead-up. Peak and mean power output were similar between the forward standing (1126 ± 49 W and 896 ± 33 W, respectively) and both the seated (1043 ± 47 W and 857 ± 29 W, respectively) and standing positions (1175 ± 45 W and 928 ± 29 W, respectively). Collectively the results from studies 2 and 3 indicate that sprinting in the forward standing position may result in an increase in sprint cycling velocity of 5.6-6.5 km·h-1 and 2.1-5.1 km·h-1, when compared with the seated and standing sprint positions, respectively. In study 4, 28 recreational road cyclists completed a two-week (3 sessions per week) sprint training intervention during which they received either i) visual and external focused verbal instructions, and positive feedback on their cycling sprint position (intervention group), or ii) neutral verbal instructions and feedback (control group). The combination of these coaching techniques did not enhance the training induced improvement in forward standing sprint performance. While improvements in peak (4%) and mean power output (3%), and peak torque (5%) were observed in both groups, it is unclear if these improvements are entirely due to the training programme because of the absence of a non-sprint training control group. This thesis has shown that sprinting in the novel forward standing sprint position could result in an increase of cycling velocity by approximately 5 km·h-1, when compared with more traditional sprint positions. In unaccustomed cyclists, sprint performance in this position might be further improved by a short two-week sprint training programme, however, further research is needed in this area. The results from this thesis have implications in training and tactical decisions of cyclists, coaches, and support staff aiming to be successful in competitive road cycling sprints.

Abstract:
Sprint cycling ability is a key determinant of road cycling performance, with many races designed specifically for sprinters. The ability to excel in the final sprint is relevant for both individual riders and teams. Despite the importance of sprints within professional road cycling, the characteristics of professional road sprints and sprinters have yet to be extensively described. Thus, the overall objective of the five research studies contained within this doctoral thesis was to describe road cycling sprint performance and improve the general understanding of the physical, technical and tactical factors associated with such performances. The first two descriptive field studies document the physical and physiological demand of sprint races during actual road cycling competitions. Specifically, Study 1 was designed to quantify the demands of sprinting in the male professional category. Seventeen competitions from six male professional cyclists (mean ± SD: age, 27.0 ± 3.8 y; height, 1.76 ± 0.03 m; weight, 71.7 ± 1.1 kg) who placed Top 5 in professional road races were analysed. Calibrated SRM power meters were used to monitor power output, cadence and heart rate. Data were averaged over the entire race, different durations prior to the sprint (60, 10, 5 and 1 min) and during the actual sprint. Variations in power during the final 10 min of the race were quantified using Exposure Variation Analysis. Power, cadence and heart rate were different between various phases of the race, increasing from 316 ± 43 W, 95 ± 4 rpm and 88 ± 3 % of maximal heart rate in the last 10 min to 487 ± 58 W, 102 ± 6 rpm and 96 ± 2 % of maximal heart rate in the last minute prior to the sprint. The peak power during the sprint was 17.4 ± 1.7 W∙kg-1. Exposure Variation Analysis revealed a significantly greater number of short duration and high intensity efforts in the final five minutes of the race, compared with the penultimate five minutes (p=0.01). These findings quantified the power output requirements associated with high level sprinting in men’s professional road cycling and highlighted the need for both aerobic and anaerobic fitness. In Study 2, the characteristics of successful road sprints in professional and under 23 y male cycling races were compared. As in Study 1, Study 2 also described the exercise intensity for the sprinters throughout final 10 min of the race. Nine successful (Top 3) sprints performed by a professional (PRO: 23 y, 1.76 m, 71.8 kg) and an under 23 (U23: 18 y, 1.67 m, 63.2 kg) cyclist sprinter were analysed in this study. No statisticaldifferences were found between PRO and U23 in the absolute peak power, mean power, duration and total work during the sprint (PRO: 1370 ± 51 W, 1120 ± 33 W, 14.5 ± 2.4 s, 16.2 ± 2.6 KJ; U23: 1318 ± 60 W, 1112 ± 68 W, 12.8 ± 1.1 s, 14.2 ± 1.4 KJ). However, the intensity of the race recorded in the last 10 min prior to the sprint was significantly higher in PRO compared with U23 (4.6 ± 0.3 and 3.7 ± 0.2 W·kg-1, respectively). Race duration, total elevation gain (TEG) and mean power were similar between PRO and U23. In conclusion, the physiological demands leading into road sprints (intensity of the last 10 min) were found to be higher in PRO compared to U23 races. Nevertheless, a similar sprint power output (> 2500 W·Ap-1 or > 15.5 W·kg-1 for approximately 14 s, with a peak power output > 3100 W·Ap-1 or > 19 W·kg-1; where Ap is Projected Frontal Area) indicates that sprint characteristics may be similar in PRO and U23. As a result of the findings observed in the first two studies of this thesis, Study 3 was designed to better understand the effects of variable and non-variable exercises that replicate the intensity of the final portion of road competitions on maximal sprint performance. In this laboratory trial, ten internationally competitive male cyclists (age, 20.1 ± 1.3 y; height, 1.81 ± 0.07 m weight, 69.5 ± 4.9 kg; and VO2max, 72.5 ± 4.4 ml·kg-1·min-1) performed a 12-s maximal sprint in a rested state and again following: i) 10 min of non-variable cycling, and ii) 10 min of variable cycling. Variable and non-variable trials were conducted in a randomized, crossover fashion. The intensity during the 10 min efforts gradually increased to replicate the pacing observed in final sections of cycling road races. During the variable cycling subjects performed short (2 s) accelerations at 80% of their peak sprint power, every 30 s. Mean power output, cadence and heart rate during the 10 min efforts were similar between conditions (5.3 ± 0.2 W∙kg-1, 102 ± 1 rpm, and 93 ± 3 %, respectively). Post exercise blood lactate concentration and perceived exertion immediately after exercise were also similar (8.3 ± 1.6 mmol∙L-1, 15.4 ± 1.3 (6-20 scale), respectively). Peak and mean power output and cadence during the subsequent maximal sprint were not significantly different between the three experimental conditions (p≥0.14). These results indicate that neither the variable nor the non-variable 10 min efforts performed within this study impaired the sprint performance in elite competitive cyclists. Due to the importance of the elevation gain variable in road cycling, the fourth study of this thesis was methodological and investigated the consistency of commercially available devices used to measure the TEG during races and training. This chapter was separated in two observational validation studies. Garmin (Forerunner 310XT, Edge 500 Edge 750 and Edge 800; with and without elevation correction) and SRM (Power Control 7) devices were used to measure TEG over a 15.7 km mountain climb performed on 6 separate occasions (6 devices; Study 4a) and during a 138 km cycling event (164 devices; Study 4b). TEG was significantly different between Garmin and SRM devices (p The final study of this thesis was an analysis of technical and tactical factors that influence sprint performance in professional competitions; particular focus was put on the TEG which was a factor identified as a potential cause of fatigue. More specifically, the subject of Study 5 was the highest international ranked professional male road sprint cyclist during the 2008-2011 seasons. Grand Tour sprint stages were classified as WON, LOST, or DROPPED from the front bunch prior to the sprint. Video of 31 stages were analysed for mean speed of the last km, sprint duration, position in the bunch and number of teammates at 60, 30, and 15 s remaining.

Abstract:
Sprint performance is one of the major determining factors for success in many land-based sports. To improve sprint performance, coaches provide task-oriented verbal instructions to athletes, which could affect how the athlete focuses their attention while sprinting. Adopting an external focus of attention has been shown to enhance a number of motor skills, including sprinting, while an internal focus of attention has been shown to be detrimental to skill performance. However, there is a current gap in the literature regarding how track and field coaches provide internal and external focus instructions to sprint and hurdle athletes during practice and competition. Additionally, there is very little research on how sprint kinematics and kinetics are changed under different attentional focus conditions. Therefore, this PhD research project assessed instructions that coaches provided to sprint and hurdle athletes during practice and competition in study one, followed by evaluating the underlying kinetic, kinematic, neuromuscular and psychophysical components of sprint performance under internal and external attentional focus conditions in comparison to a control condition during sprint acceleration in studies two and three. In study one, sprint and hurdle coaches (n = 111) completed a questionnaire consisting of a number of questions related to what type of verbal instructions they provide to the athletes they coach. It was found that the coaches provided more internal focus (54%) than external focus instructions (42%) during practice, and provided less internal focus instructions (20%) than external focus instructions (35%) or neutral focus instructions (46%) during competition. In study two, 12 trained men (age: 22.4 ± 4.0 years; height: 1.8 ± 0.1 m; body mass: 76.6 ± 6.3 kg) performed three sprint sessions separated by at least 48 hours, which included two sets of three 40 m sprints at 100% of maximal effort under control, internal and external focus conditions. Kinetics, kinematics and peak muscle activation (sEMG) were collected at ~10 m, and compared among the three conditions. Sprint times at 10 m, 20 m, 30 m and 40 m were similar between the conditions, but vastus lateralis peak sEMG activity was lower in external focus than control condition (CON: 109.4 ± 29.7%; EXT: 74.6 ± 24.8%, d = -1.28, p < 0.01). Semitendinosus peak sEMG activity was also significantly lower (p < 0.05) in the external (89.2 ± 26.4%) compared to the internal condition (108.5 ± 34.34%). No significant differences between conditions were found for other variables. In study three, 13 trained male athletes (age: 22.8 ± 3.6 years; height: 1.8 ± 0.1 m; body mass: 76.2 ± 6.6 kg) performed 6 x 10 m sprints in three conditions: control, internal, and external focus conditions, in which kinetics and kinematics from the first and second steps of the sprint acceleration were analysed. No statistical significance or moderate-to-large effect sizes were found for any of the dependent variables measured. It was concluded that simply providing an external focusing instructions to trained athletes may not necessarily result in enhanced key performance indicators or performance measures while sprinting. Collectively, these studies suggest that coaches provide more internal focus than external focus instructions during training, which may reduce movement efficiency during sprinting. The results of studies two and three did not show improved sprint performance with an external focus of attention. However, the results of study two partially supported the constrained action hypothesis in that adopting an internal focus of attention potentially disrupted the automatisation of sprinting through increasing redundant muscle activation of the semitendinosus potentially causing increased muscular co-contraction, while the external focus condition reduced muscle activation and may have potentially enhanced neuromuscular efficiency. It may be that more global, movement-oriented instructions improves sprint performance more so in trained athletes, as has been shown in previous studies. Thus, further studies are warranted.

Abstract:
The aims of this thesis were to: 1) to review research in the area of repeated sprint (RS) performance and diurnal/circadian rhythmicity; 2) to develop a new RS protocol that conforms to field based team sport time-motion analysis and determine its reliability and compare this with a RS protocol previously utilised in the literature; 3) to assess the sensitivity of the RS protocol following acute altitude exposure and simulated soccer specific exercise 4) to investigate diurnal variation of RS performance and assess whether modulating rectal and/or muscle temperatures lead to changes in RS performance. A review of the published research literature investigating the relationship between RS performance and time-of-day variation was conducted. Six studies made it through the whole analysis process for systematic review. It was established that there was evidence to support a late/early afternoon peak in peak power in RS performance around the peak of the rhythm of core temperature. However, there is a clear demand for more rigorous investigations which control factors specifically related to chronobiological investigations. A reliability study was then performed using running as the mode of exercise for the RS test using two different RS protocols to determine the number of trials required to establish high levels of reliability. The first RS test (consisting of a total of 10 sprints, 6-s in duration with 30-s of passive recovery) was a commonly used protocol in the literature and the second was a newly created RSA protocol which is better representative of field based team sports activity (consisting of a total of 10 sprints, 3-s in duration with 30-s of passive recovery). It was established that a number of performance measures of RSA non-motorised treadmill running in both protocols were reliable. However, measures of fatigue were not. Further, it was found that both protocols took 3 sessions to fully familiarise individuals. The main aim of the next study was to investigate the sensitivity of the RSA protocol by examining the effect of altitude and fatigue on RS performance. The first finding was that acute altitude exposure reduces RS performance by 3.1 to 6.5% at 1500-m and 6.2 to 12.8% at 3000-m. The second finding was that RS performance was reduced by 4.6 to 5.8% in a fatigued state. The newly created RS performance protocol is sensitive enough to detect a negative change following altitude acute exposure and a 90-min football-specific intermittent treadmill fatiguing protocol. A diurnal protocol was then employed in order to address the clear demand for more rigorous investigations in chronobiological studies of RS performance. A total of 20 participants took part in this study and it was found that RS performance was significantly higher in the evening compared to the morning ranging from 3.3 to 8.3% in all measures except fatigue index. Diurnal variation now established in RS performance, two studies assessed whether modulating rectal and/or muscle temperature leads to a change in RS performance and further determine how much can be attributed to the influence of an endogenous, temperature-dependent component. The first study (n = 12) established that raising morning rectal temperature to evening values by active warm-up did not increase RS performance to evening values. However, lowering evening rectal or muscle temperatures to morning values by pre-cooling decreased RS performance to values normally observed in the morning. The second study (n = 12) found passively raising morning rectal temperature to evening values, or passively raising morning and evening rectal temperatures to 38.5ºC did not increase RS performance nor offset diurnal variation. Both studies concluded that although central temperature may provide some endogenous rhythm to RSA, the exact mechanism(s) for a causal link between central temperature and human performance are still unclear, and may involve multiple of components and mechanisms.

Abstract:
Aerobic and anaerobic correlates of multiple sprint cycling performance. J. Strength Cond. Res. 20(4):792-798. 2006.--The aims of this study were to examine (a) the relationship between maximal oxygen uptake (O2max) and several performance indices of multiple sprint cycling; (b) the relationship between maximal accumulated oxygen deficit (MAOD) and those same performance indices; and (c) the influence of recovery duration on the magnitude of those relationships. Twenty-five physically active men completed a O2max test, a MAOD test, and 2 maximal intermittent (20 x 5 seconds) sprint cycling tests with contrasting recovery periods (10 seconds or 30 seconds). Mean +/- SD for age, height, and body mass were 20.6 +/- 1.5 years, 177.2 +/- 5.4 cm, and 78.2 +/- 8.2 kg, respectively. All tests were conducted on a friction-braked cycle ergometer with subsequent data normalized for body mass. Moderate (0.3 r < 0.5) positive correlations were observed between power output data and MAOD (range, 0.31-0.46; 95% confidence limits, -0.10 to 0.72). Moderate to large positive correlations also were observed between power output data and O2max, the magnitude of which increased as values were averaged across all sprints (range, 0.45-0.67; 95% confidence limits 0.07-0.84). Correlations between fatigue and O2max were greater in the intermittent protocol with 30-second recovery periods (r = -0.34; 95% confidence limits, 0.06 to -0.65). The results of this study reflect the complex energetics associated with multiple sprint work. Though the findings add support to the idea that multiple sprint sports demand a combination of speed and endurance, further longitudinal research is required to confirm the relative importance of these parameters.

Abstract:
In some circumstances, dietary nitrate (NO3-) supplementation can favourably alter the physiological response to exercise. Recent research highlights a potential preferential effect of NO3- supplementation on type II muscle fibre function. The purpose of this thesis was to investigate the practical applications of NO3- supplementation in sport and exercise settings requiring a substantial contribution of type II muscle fibre recruitment such as team and sprint sports. Specific questions addressed in this thesis include whether NO3--rich beetroot juice (BR) supplementation can influence the performance of sprint and high-intensity intermittent exercise and if BR supplementation, when combined with sprint interval training (SIT), can enhance performance and muscle metabolic adaptations in competitive team sport players. In addition, since cognitive performance is a key aspect of team sport performance, the effect of BR supplementation on decision-making during high-intensity intermittent exercise was also assessed. Chapter 4: Total work done during a prolonged intermittent sprint test (IST) designed to mimic the metabolic demands of team sport play was 3.5% greater following short-term BR supplementation (123 ± 19 kJ) compared to short-term NO3--depleted beetroot juice (PL) supplementation (119 ± 17 kJ) (P < 0.05). Decision-making reaction time was shorter in the second half of the IST in BR (817 ± 86 ms) compared to PL (847 ± 118 ms) (P < 0.05). Chapter 5: Short-term BR supplementation improved the performance of sprint running compared to PL over distances of 20 m (1.2% improvement; BR: 3.98 ± 0.18 vs. PL: 4.03 ± 0.19 s; P < 0.05), 10 m (1.6% improvement; BR: 2.53 ± 0.12 vs. PL 2.57 ± 0.19 s; P < 0.05) and 5 m (2.3% improvement; BR: 1.73 ± 0.09 vs. PL: 1.77 ± 0.09 s; P < 0.05). Relative to PL, BR supplementation also increased the distance covered in the Yo-Yo intermittent recovery test level 1 by 3.9% (BR: 1422 ± 502 vs. PL: 1369 ± 505 m; P < 0.05). Decision-making reaction time was shorter in BR (615 ± 98 ms) compared to PL (645 ± 120 ms) (P < 0.05) at rest but not during the Yo-Yo IR1 test. Chapter 6: 4 weeks BR ingestion significantly reduced the O2 cost of moderate intensity exercise (by 5%; P < 0.05) and significantly increased the peak work rate (WR) attained during incremental exercise (P < 0.05). When 4 weeks SIT was combined with 4 weeks of BR ingestion, peak WR increased more than when SIT was combined with PL supplementation (SIT+BR: 24 ± 8 W increase vs. SIT+PL: 16 ± 15 W increase; P < 0.05). Although the change in time to task failure during severe-intensity exercise was not statistically different between SIT+BR (69% increase) and SIT+PL (55% increase), there was evidence of a more favourable muscle metabolic response to severe-intensity exercise in SIT+BR. Specifically, at the 3-min iso-time during severe-intensity exercise, muscle pH was higher and muscle (and blood) [lactate] was lower in SIT+BR only (P < 0.05). These findings demonstrate that BR supplementation may be ergogenic in sprint cycling, sprint running and high-intensity intermittent exercise and that when combined with SIT, BR supplementation may enhance the resultant exercise performance adaptations and some muscular adaptations to exercise. The results of this thesis also suggest that BR supplementation may improve cognitive performance, specifically decision-making reaction time, during team sport exercise.

Abstract:
AbstractThe valve train plays a major role in the performance of internal combustion engines by controlling the combustion process and it is therefore one of the key aspects for increasing the efficiency of combustion engines. Considering the dynamics, the spring force must be high enough to reliably close the valve preventing from seating bouncing due to surge modes after the valve closure. On the other side, the spring force should be kept as low as possible in order to reduce the engine friction losses and consequently the fuel consumption. In the high-performance engines, the valve springs have to be designed and optimized for sustaining higher stresses with compact dimensions leading to critical material and manufacturing processes. This requires a reduction of moving masses and a strong focus on design and process optimization of the coil springs for reducing the mechanical load and the friction losses at low engine speed. At the same time, valve train should be reliable at high engine speed. The calculation of stresses and contact forces for moving parts under dynamic load is essential for durability analysis. A method to calculate the contact of moving masses is described and proposed to justify valve motions experimental results. To fully understand the failure mechanism of test bed reliability trials, the dynamic stresses have been calculated modeling the real springs’ shape. The contact forces have been reproduced considering the coil clash effects and the dynamic behavior of the flexible spring.

Abstract:
Elite sprinters are differentiated from merely good sprinters by their performance during the first 20 m of a 100 m race [1]. The impulse of the ground reaction force in the forward direction during the sprint start has been found to correlate negatively with overall race time indicating that the best sprinters are the ones who are able to accelerate rapidly at the start of a race. Many factors have been examined to determine the anatomical and physiological characteristics that contribute to sprinting ability, including muscle fiber type, muscle size, and muscle architecture parameters such as fascicle length and pennation angle. Joint structure has received less attention, although it has the potential to influence sprint performance in complex ways.

This paper demonstrates that good governance in one country can influence governance improvements in neighboring countries and highlights that regional political and economic cooperation can benefit institutional development across borders. Governance has a spatial dimension due to spillovers and resource flows across juridical boundaries. This paper finds that governance in a given country—manifested most clearly through voice and accountability—exhibits a positive relationship with those in neighboring countries. Feedback mechanisms are traced in that any change in the income level of a country can affect its governance performance and also impact the governance scores of neighboring countries. This phenomenon is observed in the “Arab Spring,” “Me Too,” and “Black Lives Matter” cross-border movements

Abstract:
The pandemic hit the Colombian economy as hard as other countries. Using a novel Business Pulse Survey, this paper tests the effect of government support and COVID-19 cases on firms performance. A one-standard-deviation increase in government support (in periods in which the pandemics intensity was average) increased the percentage of firms reporting normal operations by 4.8 percent. Political demonstrations in spring 2021, however, reduced the percentage by 13 percent each month they lasted. Firms' financial distress also counters the impact of government support, suggesting the need to ease firms' access to financial markets. Last, we show that investing in digital solutions improved firms' performance but remote work degraded it.
