Knee Extensor Maximal Voluntary Contraction Torque During the Treadmill Exercise Study

Writer:realleaderfitnessDate:2016-12-24 09:21:19
Maximal voluntary isometric contraction (MVIC) torque of the knee extensor muscles was measured before and immediately after the treadmill exercise (POST) to quantify any induced muscle fatigue. This test was performed on the right knee extensors with an isokinetic system (System pro, Biodex Medical System, New-York). MVIC was defined as the best performance obtained on two consecutive trials (1-min rest in between). Participants were seated comfortably and attached with a noncompliant strap on the trunk and ankle above the malleoli with knee angle of 70° (0°= leg extension) and hip angle of 90°. They performed a specific warm up prior to the PRE test to become accustomed to the movement and torques developed. The warm-up included several leg extensions at different angular velocities and two 5-s submaximal isometric contractions. Participants were verbally encouraged during each trial to perform the best performance possible.
