ASSESSMENT OF HAMSTRING MUSCLE VOLUNTARY ACTIVATION: IMPACT OF CONTRACTION MODE AND PREVIOUS INJURY

Background Hamstring strain injury (HSI) burdens athletes due to high occurrence and recurrence rates. Previous surface EMG evidence suggests reduced voluntary activation (VA) may contribute to high ...

Impact of contraction intensity and ankle joint angle on calf muscle fascicle length and pennation angle during isometric and dynamic contractions

During muscle contraction, not only are the fascicles shortening but also the pennation angle changes, which leads to a faster contraction of the muscle than of its fascicles. This phenomenon is ...

Antagonist muscle torque at the ankle interfere with maximal voluntary contraction under isometric and anisometric conditions

The ICC scores are presented in Table 1 for both PF and DF MVCs. Measurements in PF MVC showed excellent reliability with ICC ranging from 0.81 to 0.90, and the TA antagonist torque in eccentric ...

Muscles, movement and muscle contraction

The origin is the end of a muscle which is attached to a fixed bone. The insertion is the other end of the muscle that is attached to the bone which moves. Muscular contractions are defined as the ...
