Isokinetic strength evaluation of the knee flexion and extension in concentric mode of contraction is an important part of the comprehensive evaluation of athletes. The aims of this study were to evaluate the isokinetic knee peak torque in both the extension and flexion movement in the dominant and non-dominant leg, and the relationship with jumping performance. Twelve elite male handball playe...

Context: Athletes are often examined for return to sports using a functional-testing algorithm. No research has determined whether a closed kinetic chain (CKC) isokinetic testing bout influences the reliability of functional tests. Objective: To determine whether a concentric CKC isokinetic test bout alters test–retest reliability of lower extremity functional testing. Design: Subjects particip...

OBJECTIVE To measure the sensitivity and specificity of differences cut-off values for isokinetic Hcon/Qcon ratio in order to improve the capacity to evaluate (retrospectively) the injury of hamstring muscles in professional soccer screened with knee isokinetic tests. DESIGN Retrospective study. METHODS Medical and biomechanical data of professional football players playing for the same tea...

BACKGROUND: Isokinetic testing is often used to provide coaches with important information about the physical status of athletes. Therefore, a number of studies is focused on the assessment of the relationship between isokinetic and functional tests. The results of a limited number of studies indicate that the relationship changes in different training periods. OBJECTIVE: The aim of the study w...

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 flexor...

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...

Background: Isokinetic dynamometry allows the measurement of several variables related to muscular performance, many of which are seldom used, while others are redundantly applied to the characterization of muscle function. Objectives: The present study aimed to establish the particular features of muscle function that are captured by the variables currently included in isokinetic assessment an...

The aim of the present study was to examine whether or not the compliance of the gastrocnemius medialis (GM) tendon and aponeurosis is influenced by submaximal fatiguing efforts. Fourteen elderly male subjects performed isometric maximal voluntary plantarflexion contractions (MVC) on a dynamometer before and after two fatiguing protocols. The protocols consisted of: (1) submaximal concentric is...
