Reproducibility of the time to peak torque and the joint angle at peak torque on knee of young sportsmen on the isokinetic dynamometer

Annals of Physical and Rehabilitation Medicine, 2012
Although peak torque has shown acceptable reproducibility, this may not be the case with two other often used parameters: time to peak torque (TPT) and the angle of peak torque (APT). Those two parameters should be used for the characterization of muscular adaptations in athletes.The isokinetic performance of the knee extensors and flexors in both ...

Rotational and peak torque stiffness of rugby shoes

The Foot, 2014
Sports people always strive to avoid injury. Sports shoe designs in many sports have been shown to affect traction and injury rates. The aim of this study is to demonstrate the differing stiffness and torque in rugby boots that are designed for the same effect.Five different types of rugby shoes commonly worn by scrum forwards were laboratory tested ...

Potentiation Increases Peak Twitch Torque by Enhancing Rates of Torque Development and Relaxation

Journal of Human Kinetics, 2013
Abstract The aim of this study was to measure the extent to which potentiation changes in response to an isometric maximal voluntary contraction. Eleven physically active subjects participated in two separate studies. Single stimulus of electrical stimulation of the femoral nerve was used to measure torque at rest in unpotentiated quadriceps ...

Changes in Hamstring Eccentric Peak Torques and Angles of Peak Torque Following 90 Minutes of Soccer Specific Exertions

Malaysian Journal of Movement, Health & Exercise, 2020
This study aimed to investigate the effects of a ball-oriented soccer match-play simulation on the hamstrings eccentric torque production. Seven male recreational athletes volunteered for this study. Participants completed 90-minutes of the ball-oriented soccer simulation interceded by a 15-minute half time interval with five successful trials of ...

Lower extremity injury in female basketball players is related to a large difference in peak eversion torque between barefoot and shod conditions

Journal of Sport and Health Science, 2014
Background: The majority of injuries reported in female basketball players are ankle sprains and mechanisms leading to injury have been debated. Investigations into muscular imbalances in barefoot versus shod conditions and their relationship with injury

Prediction of torque acceleration energy and power of thigh muscles from peak torque

Medicine & Science in Sports & Exercise, 1989
The purpose of this study was to assess the relationship between the isometric and isokinetic peak torque (PT) (speed of movement 0, 60, and 180 degrees.s-1) and the peak torque acceleration energy (PTAE) and average power (AP) of multiple contractions (180 degrees.s-1) of the quadriceps and hamstrings in 38 patients having a chronic, complete anterior

Investigation of The Hamstrıng/Quadriceps Ratio, Time to Peak Torque and Joint Angle at Peak Torque Characteristics of Female Soccer Players

The Online Journal of Recreation and Sports, 2023
It is thought that time to peak torque and joint angle at peak torque parameters provide important data for the functional evaluation of quadriceps and hamstring muscles. It is known that studies with these parameters are rare in the literature. The aim of this study is to investigate the relationship between hamstring/quadriceps (H/Q) ratio, time to ...

Test-Retest Intra-Session Reliability of Isokinetic Knee Strength Measurements in Obese Children

Applied Sciences, 2020
Background: Childhood obesity is one of the most critical global health challenges. Poor knee extensor strength is associated with disability and difficulties with physical function in obese patients.

A cross‐sectional study comparing passive and eccentric modes of an isokinetic dynamometer to assess eccentric torque in trained athletes: Methodological considerations

European Journal of Sport Science
Some technical limitations to using the eccentric mode to measure peak eccentric strength of the hamstrings (PTHecc) were raised. PTHecc also has limited validity to predict performance or injury risk factor.
