简要总结
Proper functioning of the ankle musculature, specifically peroneal muscles, is crucial for maintaining balance and reducing the risk for falls. Evidence suggests that a decrease in aspects of neuromuscular control already starts at midlife (45-65 years). However, there is almost no information regarding the function of the ankle muscles at the middle-age as most experiments have compared young (<35 years) and older subjects (>65 years). Moreover, neuromuscular training can improve the function of ankle muscle in response to perturbation; yet, no previous study has compared the level of effectiveness between middle-aged and young adults.

结局指标
主要结局
Time to stabilization
时间窗: Within 24 hours
Subjects will be asked to jump from a 20 cm high box onto a force plate (i.e., expected fall).
Electromyography of peroneus longus- "Time to Onset"- expected fall
时间窗: Within 24 hours
Subjects will be asked to jump from a 20 cm high box onto a force plate (i.e., expected fall). electromyography of peroneus longus will be measured the "Time to Onset" - expresses the period that passes from the beginning of the fall to the initial recruitment of the Peroneus longus.
Electromyography of peroneus longus- "Time to Peak"-unexpected fall
时间窗: Within 24 hours
Subjects will stand on a platform during a unilateral sudden 30° inversion platform perturbation that resembles an unexpected fall. electromyography of peroneus longus will be measured the "Time to Peak"- describes the time it takes for the Peroneus longus muscle to reach the peak of its electrical activity.
Electromyography of peroneus longus- "The height of the amplitude"- expected fall
时间窗: Within 24 hours
Subjects will be asked to jump from a 20 cm high box onto a force plate (i.e., expected fall). electromyography of peroneus longus will be measured the height of the amplitude - expresses the peak of the electrical activity of the muscles.

Subjects will stand on a platform during a unilateral sudden 30° inversion platform perturbation that resembles an unexpected fall. electromyography of peroneus longus will be measured the "Time to Onset"- expresses the period that passes from the beginning of the fall to the initial recruitment of the Peroneus longos muscle.
Maximal voluntary isometric peroneal contraction force
时间窗: Within 24 hours
Subject will perform Maximal voluntary isometric peroneal contraction. The force will measured with dynamometer
