EVALUATION OF TORQUE-VELOCITY CURVE AND MAXIMAL POWER OUTPUT OF KNEE EXTENSOR UNDER ISOKINETIC CONTRACTION

The Comparison of Isokinetic Parameters of Hip and Knee Joint Muscles in Professional Soccer Players with Athletic Groin Pain and Healthy One: Implications for Sports Injuries Prevention

Aims and background: This study aimed to investigate the comparison of isokinetic parameters of hip and knee joint muscles in professional soccer players with athletic groin pain (AGP) and healthy ones. Material and Methods: 32 soccer players (control group (n=16) and AGP group (n=16)) who take part in the first and second division league participated in this study. The isokinetic dynamometer ...

Relationship 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...

Total power output generated during dynamic knee extensor exercise at different contraction frequencies.

A novel approach has been developed for the quantification of total mechanical power output produced by an isolated, well-defined muscle group during dynamic exercise in humans at different contraction frequencies. The calculation of total power output comprises the external power delivered to the ergometer (i.e., the external power output setting of the ergometer) and the "internal" power gene...

Potentiation of isokinetic torque is velocity-dependent following an isometric conditioning contraction

Not only twitch torque but also the maximal voluntary concentric torque increases after a high-intensity contraction (conditioning contraction). The purpose of this study was to test the hypothesis that the increase in the maximal voluntary concentric torque induced by a conditioning contraction is prominent when tested at fast angular velocities conditions. Twelve healthy male participants per...
