The burden of hip muscles weakness and its relation to other impairments has been well documented. It is therefore a pre-requisite to have a reliable method for clinical assessment of hip muscles function allowing the design and implementation of a proper strengthening program. Motor-driven dynamometry has been widely accepted as the gold-standard for lower limb muscle strength assessment but i...

The purpose of this study was to investigate the between-session reliability of common strengthand power-related measures in adolescent athletes. Seventeen adolescent athletes (males: n = 8: age 17.1 ± 2.2 years; height 175.6 ± 3.5 cm; mass 80.2 ± 3.6 kg; females: n = 9; age 16.9 ± 2.6 years; height 178.5 ± 4.3 cm; mass 71.5 ± 4.5 kg) participated in this study. Isokinetic dynamometry, isometri...

Twenty-six men on a liver transplant waiting list (12 had alcoholic cirrhosis, 8 suffered from posthepatitic cirrhosis, and 6 from cirrhosis of other etiologies) were eligible for this observation. Nineteen subjects underwent exercise testing to determine oxygen uptake at anaerobic threshold. In all patients dynamometry was performed to determine isokinetic muscle strength of knee extensor musc...

The purposes of this study were (a) to determine whether a significant strength imbalance existed between the left and right or dominant (D) and nondominant (ND) legs and (b) to investigate possible correlations among various unilateral and bilateral closed kinetic chain tests, including a field test, and traditional isokinetic dynamometry used to determine strength imbalance. Fourteen Division...

The aim of this study was threefold (1) to assess the reliability three upper-extremity performance tests: a countermovement push up, press jump and drop box land, performed on set dual-force plates (2) examine whether there an association between isokinetic dynamometry tests in non-injured cohort collision/contact athletes (3) establish normal descriptive profile vertical ground reaction force...

PURPOSE This study evaluated the effect of remote voluntary contractions(RVC) on concentric isokinetic knee extensor and flexor peak torque, rate of torque development, power, and work, the activation of the affected muscles, and gender differences therein. METHODS Eleven men and 12 women were evaluated with EMG and isokinetic dynamometry during knee extension and flexion tests in RVC and bas...

Netball is a multidirectional sport afflicted by relatively high proportion of lower-extremity injuries. The purpose this study was to evaluate the relationships between landing stabilisation times, unilateral kinetics, and isokinetic knee joint torques in elite female netball players. A total 15 players volunteered for (age: 20.80 ± 1.42 years; height: 1.75 0.06 m; body mass: 71.69 13.58 kg). ...

OBJECTIVE The objective of this study was to conduct a comparative analysis on isokinetic strength assessments between field and indoor male professional soccer players and correlate the findings with the higher levels of injury risk described in the literature. METHODS We analyzed 16 field soccer players and 15 indoor soccer players. All these professionals were male. Isokinetic muscle stren...

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...
