Concerning the effects of an acute stretching regimen on maximal isokinetic concentric knee extension torque at 5 different angular velocities, it has been demonstrated that there were signiï¬ cant reductions in torque at the lower angular velocities of 60 â ¦ /s and 90â ¦ /s, while at the higher velocities of â ¦ /s, â ¦ /s. An investigation was made of the influence of age and sex on peak muscle torque in knee extension and flexion during maximal isokinetic and isometric contraction. The study was performed on both legs of clinically healthy men and clinically healthy women a 30, 40, 50, 60 or 70 years.

The purpose of this study was to examine the effects of moment of antagonistic muscle on the resultant joint moment during isokinetic eccentric and concentric efforts of the knee extensors. Ten males performed maximum eccentric and concentric knee extension and flexion efforts on a Biodex dynamometer at rad s−1 (30° s−1).Cited by: The purposes of these studies were to determine if an acute static stretch influenced isokinetic peak torque (IPT), and to examine if the order in which the warm up routine was performed affected peak knee extension torque. Twenty trained college male students performed maximal isokinetic knee extensions under four conditions: a control consisting of no stretching, a stretch only trial, jog Author: Eric J. Sobolewski.

For example, a previous study found a positive effect of a closed chain on torque production during isokinetic knee extension and flexion (10). It was found that stabilizing the upper body using. In addition, back stabilization was less than hands and back stabilization, pCited by: THE EFFECTS OF ISOKINETIC TRAINING OF HIP MUSCLES ON GAIT PERFORMANCE IN ABOVE-KNEE AMPUTEES Choochuay S.1, Kaewwongkot C.1, Wongphaet P.2 and Tipchatyotin S.1 Department of Orthopaedic Surgery and Physical Medicine, Faculty of Medicine, Prince of Songkla University, Songkla, Thailand1 2Samrong General Hospital, Sumutprakarn, Thailand.
We recruited subjects with bilateral knee osteoarthritis (Altman Grade II) to compare the effects of different stretching techniques on the outcomes of isokinetic muscle strengthening exercises.
effects of different stretching techniques on the outcomes of isokinetic muscle strengthening exer-cises. Patients were randomly divided into four groups (I–IV). Measurement of isokinetic peak torque during knee flexion and extension The peak torque of the arthritic knee was measured using a method modified from Snow and Blacklin.
A significant difference was also not observed between the treatment effects in the overall percentage changes of combined knee extension and flexion during the isometric contractions (SM ± vs sham ±P), isokinetic contractions at 60°/s (SM − ± vs sham − ±P), or isokinetic contractions Cited by: 2.
Considering the mean and standard deviation (± SD) of the beginning of the stabilization of the isokinetic velocity (on a scale from 0 to % of the movement) in the concentric and eccentric activities, it was observed that: during the horizontal AB 6 ± % and AD ± %, FL ± % and EX ± % in the concentric activity and.

Concerning the MPT location in the torque curves in the shoulder flexion movements. In the analysis of the peak torque angle, when comparing the right with left sides, a statistically significant difference was found only in the CG, in the flexion movement at 60°/s (P = ), in which the peak torque angle was greater on the left n the RA and CG, there were statistically significant differences only in the extension movement to the right at °/s (P = Cited by: Torque and joint angle signals, as well as quadriceps and hamstrings electromyographic (EMG) signals, were recorded during maximal knee flexion/extension at speeds of 60,and °s−1.

Patients who received isokinetic training had significantly greater changes in knee flexion ( ± ° vs. ± °, P = ) and knee extension. Twenty-three subjects isokinetically trained the right and left quadriceps femoris, three times per week for 16 weeks; one group (n=13) trained at an angular velocity of rad s−1 and a second group (n=10), at rad s−1.
A control group (n=10) performed no training.

creasing isokinetic quadriceps peak torque values or thigh girth in a noninjured subject population. This drastic reduction in vertical feet climbed from Friday to Monday was adopted due to the clinical observa- tion that some patients develop knee effusion and/or patellofemoral symp- toms during knee rehabilitation when increasing step height.
OBJECTIVE: To evaluate the improvement rate of quadriceps muscle peak torque in healthy subjects and patients with burn injuries after an isokinetic training programme. SUBJECTS: Thirty male volunteers, 15 healthy and 15 subjects with burn injury after complete healing, participated in the study.
METHODS: Concentric and eccentric torque of quadriceps was measured for both groups using an. Barnes found that the isokinetic fatigue curve for knee extension was linear during the initial stages of the process, and the fatigue curves were essentially identical regardless of velocity.

Knee joint forces during isokinetic knee extensions have been reported in four studies. In a study by Nisell et al. (), eight male subjects performed knee extensions at two speeds (30 and °/s).
Inertial effects. Isokinetic tests can be used to diagnose PFJ dysfunction and monitor treatment progress. Anterior cruciate ligament (ACL) deficiency: There is usually a plateau or double peak that occurs in the midportion of knee extension. See below. This is because the ACL controls a portion of the glide and rotation during mid range knee extension.placed across the hips and distal thigh for stabilization.
The dynamometer's axis of rotation was aligned with the anatomical axis of the knee joint, and the shin pad was placed one to inches proximal to the lateral malleolus.
