Muscle strength, as measured by isometric maximal voluntary contractions in both straight and bent-knee calf exercises, improved in both groups.

在直膝和屈膝的小腿运动中，通过等长最大自主收缩来测量的肌肉力量在两组中都有所改善。

The isometric was an elbow flexion, aka a bicep curl, at maximal contraction held for 3 seconds 10 times at a 20-degree flexion.

精力训练是做肘部屈曲，也就是二头肌弯曲，以极限收缩保持3秒，以20度屈曲10次。

Isometric training two days before fast and slow eccentric training led to lower reductions of maximal voluntary contraction, and yes, smaller increases in muscle soreness.

在做快速和缓慢的离心训练前两天进行静力训练，可以降低最大自主收缩的减少，是的，肌肉酸痛的幅度也更小。
