Full textAim: To describe the relationship between strength tests and sports specific performance factors in female and male youth national team basketball players. What does the relationship between vertical jump ability, sprint and back squat strength look like? What does the relationship between vertical jump ability, sprint and hang clean strength look like? How does sex, age, 1RM hang clean and 1RM squat influence jump height and sprint time, together and respectively. How does sex, age, 1RM hang clean (% of body weight) and 1RM squat (% of body weight) influence jump height and sprint time, together and respectively. Method: The study design was a cross-sectional study where the analyzed data comes from the Swedish basketball federation and has been collected during female and male youth national team camps at U16, U18 and U20 levels since 2001. To examine the data correlation and regression analysis where carried out between 1 repetition maximum (1RM) back squat, 1RM hang clean and counter movement jump with arm swing (CMJ(a)) and 10, 20 and 30 meter sprint. Results: The result shows significant correlations between strength tests and vertical jump ability and sprinting speed for both female and male basketball players. The regression analysis show that sex has great influence on the CMJ(a) and sprints where men perform significantly better then women. Further analysis also shows that except from sex, 1RM back squat and 1RM hang clean in relation to body-weight significantly contributes to higher vertical jumps during CMJ(a) and faster sprints at 10, 20 and 30 meters. Conclusions: This study together with previous research strengthen the idea that 1RM back squats and hang clean in relation to body weight enhances individual physical properties that is perceived to be important for basketball performance such as vertical jump ability and sprints.

Full textSyftet med denna rapport är att ta reda på styrketesternas funktion på polisutbildningen vid Umeå universitet. Som bakgrund till rapporten ligger bland annat egna iakttagelser om stora skillnader i resultatet vid styrketesterna. Tillvägagångssättet har bestått av intervjuer med momentansvariga för styrketesterna, tidigare lärare samt inläsning på ämnesområdet. Under teoridelen förklaras styrketesternas olika moment, uppbyggnad och krav. I rapporten beskrivs rikspolisstyrelsen krav om en specifik utbildningsplan. Utbildningsplanen för polisutbildningen i Umeå består av olika kurser och moment. Under momentet ”Hälsa i teori och praktik” som bedrivs fortlöpande under hela utbildningen genomförs styrketesterna under termin tre. Vid utformningen av styrketesterna gjordes jämförelser med andra länders polisutbildningar och andra yrkeskategorier i Sverige. Problematiken vid utformningen av styrketester beror på stor del att det saknas en utformad fysisk kravprofil för polisyrket. Utifrån den förutsättningen genomförs dagens styrketester på bästa sätt.

Full textIntroduction: A complex interaction between muscles, tendons, bones, joints and nerves are required for optimal function of the human hand. It is known that an individual’s grip strength is vital for performance of physical demanding tasks such as strength training with free weights. Strength training including a thicker grip around the bar may enhance the strength of the grip in the athlete without other special routines for grip strength development. The purpose of this investigation was to examine the difference in performance in multiple repetitions in two strength training exercises using two different sizes on the bar, to look for correlations between grip strength of the subjects hand and the amount of repetitions executed with two different size of the bar and finally the correlation of hand size and the amount of repetitions executed with two different size of the bar.
Method: 15 strength training men (23,9 ± 4,1 years), underwent measurements of hand size, maximum grip strength, 1 repetition maximum (1RM), a 80 % of 1RM weight strength test with two different bar sizes.
Results: The results from the present investigation indicates a 21,1 % reduction of 80 % of 1 RM weight performance in repetitions executed in the bench press with the thicker diameter of the bar and a 66,2 % reduction in repetitions executed with a 80 % of 1 RM weight in the lying bench row with the thicker diameter of the bar. The size of the hand or the maximum grip strength does not influences the performance in the 80 % of 1 RM strength test.
Conclusion: With support of the results from this present investigation the size of the bar diameter significant influences the performance in maximum repetitions executed in a set in strength training with free weights, in a rowing exercise the repetitions executed reduced with 66,2 % and in the bench press the reduction of executed repetitions were 21,1 % with the thicker diameter of the bar. The size of the hand do not influences the performance of maximal executed repetitions with the thicker bar diameter. Maximal grip strength has no influence of the performance according to the findings of this investigation.

Full textIntroduction: Pain from the hip has in studies shown to result in reduced strength. Few studies have tested dynamic strength in the hip muscles using elastic bands, despite being common in the rehabilitation of patients. Purpose: The purpose of the study was to investigate dynamic abduction and external rotation strength of the hip in patients with unilateral disorders compare with the healthy side. It was hypothesised that patients with lateral hip pain would be weaker on the affected side compared to the healthy side. Method: Twenty patients with unilateral hip pain receiving physical therapy were tested for abduction and external rotation strength in the hip. The painful side was compared to unaffected side with a test device that consisted of an elastic band that was serially coupled with a tie strap. A tape measure was attached so that the length of the elastic band could be read. Results: No statistical difference was found between the painful side compared with the healthy side in abduction strength. The mean of the dynamic strength was 7.4 ± 2.9 kg for the painful side and 7.9 ± 2.3 kg for the healthy side. The mean of the dynamic force in external rotation was 8.4 ± 3.6 kg for the painful side and 8.8 ± 2.3 kg for the healthy side. No significant differences was found. Conclusion: Patients with unilateral pain from abduction and external rotation muscles showed no lateral disability in dynamic strength. Studies show that they have poorer strengths compared to painless individuals. The reason why no side difference in hip strength was noted is unclear but could perhaps be explained by a factor such as the patients hip pain levels.

Full textRock climbing performed on overhanging surfaces is becoming more common and requires more advanced use of the lower body. Since previous research has mostly examined upper body strength there is a need for a muscular profiling of the lower body of climbers, which was the purpose of this study. The study sought to investigate whether differences in strength and power in the lower extremities can be related to climbing performance in male climbers. The participants were 10 male amateur climbers divided into two groups based on athletes-specific performance level. Group 1 (n=6) where categorized as advanced climbers and group 2 (n=4) as moderate. An isokinetic strength test and two different jump tests were performed by all study participants. After statistical analysis, there were no significant differences (p= 0,05) between the groups in relative strength in the quadriceps, relative strength in hamstrings, H/Q-ratio, jump height at SJ or jump height at CMJ. The group with more advanced climbers performed significantly higher at CMJ versus SJ (p = 0.013). The conclusions of this study are that climbers have relatively low results when measuring H/Q-ratio at 90°/s (group 1: 51% vs. group 2: 53,9%), 210°/s (59,4% vs. 57,9%) and height at vertical jump tests (SJ: 32,1cm vs. 31,7cm; CMJ: 35,8 cm vs. 33,9 cm) and that jump technique seems to be a contributing factor in climbing performance.
