摘要

Fatigue of lower extremity muscles is known to impact balance and increase the risk of falls and injuries. Among muscle groups of the lower extremity, the ankle plantar flexors generally are viewed as the most influential for control of posture, especially when the human body is modeled as an inverted pendulum. On the other hand, both plantar flexors and dorsiflexors of the ankle, and the flexors and extensors of the knee, have similar effects on the control of posture when fatigued. The specific role of quad-riceps muscle group (QU) in control of posture, however, is not completely understood. The function of QU is particularly important during the performance of numerous athletic activities that challenge postural control.
