Background Isokinetic strength and hop tests are commonly used to assess athletes' readiness to return to sport after knee surgery. Purpose/Hypothesis The purpose of this study was to investigate the results of single-leg hop and isokinetic knee strength testing in athletes who underwent anterior cruciate ligament reconstruction (ACLR) upon returning to sport participation as well as to study...

The Effect of Static Stretching and Order of Warm-Up on the Isokinetic Peak Torque of the Knee Extensors

The goal of exercise rehabilitation is to return to the conditions necessary to be able to engage in specific sports or general physical activity. This type of rehabilitation may be called ‘functional treatment’. Functional treatment is symptom guided, injury specific, and sports specific. Recently, many exercise scientists emphasize that functional treatment should be initiated as soon as poss...

Isokinetic dynamometers may provide a useful means of measuring muscle stiffness resulting from eccentric exercise because they can measure torque from computer-controlled passive movements of joints (passive resistive torque; PRT). In this study, a Biodex measured increased ankle PRT (52%; p <.001) following heel drop exercise in nine young women. Therefore, isokinetic dynamometers can provide...

We demonstrate why for a sheared gas of hard spheres, described by the SLLOD equations with an isokinetic Gaussian thermostat in between collisions, deviations of the conjugate pairing rule for the Lyapunov spectrum are to be expected, employing a previous result that for a large number of particles N, the isokinetic Gaussian thermostat is equivalent to a constant friction thermostat, up to 1/s...

This study was conducted to measure isometric (static) and isokinetic (dynamic) back and arm lifting strengths at 20, 60 and 100 cm s-1 of young adults. Ten male and ten female volunteers without a history of back pain participated. The isokinetic lifting task was achieved by controlled motorized dynamic strength tester (DST). A regression analysis and analysis of variance was carried out on th...
