چکیده

background :this paper explores the gender-related bilateral differences of extensor and flexor torques of the knee joint at low and high angular velocities in iranian healthy males and females.   methods : 70 healthy subjects (29 males (26.61±4.34 yrs and 41 females with average age of 23.07±3.70 yrs)) were participated in this study. isokinetic peak torque values for knee extensors and flexors in concentric and eccentric contraction modes were measured and flexors and extensors strength ratios (hqr) computed among both dominant and non-dominant legs in lying position at 60 and 180°.s-1angular velocities.   results : there was significant gender-velocity interactions detected for knee flexor to extensor strength ratios presenting that increasing velocity escaled this, ratios in females more than males(p< 0.05). there was no gender-velocity-leg side interaction (p>0.05). bilateral differences were found for eccentric flexor peak torques (p< 0.05). by increasing velocity, peak torque values decreased and hqr was increased (p< 0.05).   conclusion : measurement procedures including test position is an important factor when interpreting gender- related and bilateral differences of isokinetic knee strength ratios in healthy individuals.

Isokinetic dynamometry of knee flexors and extensors: comparative study among non-athletes, jumper athletes and runner athletes.

UNLABELLED Participation in intensive sports activities leads to muscular specializations that may generate alterations in involved articular forces and cause static (posture) and dynamic changes (alterations of articular stability, coordination, etc.). Prevention of injury requires specific functional muscular evaluation in all athletes and for any kind of sport. OBJECTIVE To dynamically eva...

Isokinetic strength and endurance of the knee extensors and flexors in trans-tibial amputees.

Significant levels of muscular fatigue alter the co-ordination patterns and the ability to accomplish proper daily functions, especially in patients with initial low levels of strength. The purpose of this study was to evaluate the strength and endurance of the quadriceps and hamstring muscles in trans-tibial amputees. Concentric strength and endurance of the thigh muscles were measured bilater...
