Seasonal Variation in Isokinetic Peak Torque in Youth Soccer Players
The aim of the study was to investigate the seasonal variation in the strength of the knee flexors and extensors in highly trained youth soccer players. The players (n=16; age 16.7±0.7) were measured at the end of the competitive season, at the beginning of the off-season and during the sixth week of a new competitive season. Isokinetic concentric peak torque was measured at 60°·s-1, 180°·s-1, ...
متن کاملRelationship between Isokinetic Average Force, Average Torque, Peak Force, and Peak Torque of the Knee Extensor and Flexor Musculature
The purpose of this study was to determine the relationship between average force, average torque, peak force, and peak torque produced by the knee musculature. Twenty women were assessed for isokinetic concentric and eccentric knee extensor and flexor muscular strength at a velocity of 90 deg/sec. Correlational analyses showed relationships ranging from r = 0.89 to r = 0.94 for concentric exte...
متن کاملIsokinetic Strength, Ipsilateral and Bilateral Ratio of Peak Muscle Torque in Knee Flexors and Extensors in Elite Young Soccer Players
The aim of the study was to determine the profile of isokinetic strength of elite young soccer players (n = 12, mean age 17.5 ± 1.5 years). Assessment was performed on the isokinetic dynamometer. We evaluated: maximum peak muscle torque of knee extensors (PTE) and flexors (PTF) in both legs, ipsilateral ratio of muscle torque for both preferred and non-preferred extremities (H:QP and H:QN, resp...
متن کاملIsokinetic torque peak and hamstrings/quadriceps ratios in endurance athletes with anterior cruciate ligament laxity.
PURPOSE To evaluate torque and the hamstring/quadriceps ratio of the knee of athletes with and without anterior cruciate ligament laxity. METHODS Twenty-eight male athletes, 19 without anterior cruciate ligament laxity and 9 with anterior cruciate ligament laxity, were evaluated with an isokinetic machine model Cybex 770. The peak torque of quadriceps and hamstrings was compared, and the hams...
متن کاملHamstrings to quadriceps peak torque ratios diverge between sexes with increasing isokinetic angular velocity.
Our purpose was to determine if females demonstrate decreased hamstrings to quadriceps peak torque (H/Q) ratios compared to males and if H/Q ratios increase with increased isokinetic velocity in both sexes. Maturation disproportionately increases hamstrings peak torque at high velocity in males, but not females. Therefore, we hypothesised that mature females would demonstrate decreased H/Q rati...
