Abstract

Isometric twitch contractions have been studied in extensor hallucis brevis muscles of 32 healthy male subjects aged between 3 and 25 years. The maximum twitch tensions were found to increase gradually with age and then to undergo marked enhancement at puberty. After puberty little further change occurred. In the youngest children examined the twitch contraction times were already within the adult range, though the half-relaxation times were prolonged.

摘要

对32名年龄在3至25岁之间的健康男性受试者的拇短伸肌进行了等长收缩研究。发现最大收缩张力随年龄逐渐增加，然后在青春期显著增强。青春期后几乎没有进一步变化。在接受检查的最年幼儿童中，收缩时间已在成人范围内，尽管半松弛时间延长。
