Mental sweating plays an important role to make handgrips smooth. This study examined the relationship between mental sweating and handgrips focusing on the timing of sweat secretion. Five students were instructed to grip a soft ball (nine centimeters diameter) as strongly as possible. Electrodermal and sweating responses were collected from five seconds before to five seconds after the beginning of their handgrips. The results showed that electrodermal responses increased one second before the beginning of the handgrip, and that sweating responses one second after. These results suggest that sweating responses in handgrip performance show a different response pattern from the electrodermal responses. Readiness for handgrip performance required for the maximum might evoked electrodermal responses before the performance, and this process facilitated sweat secretion as the strength of the handgrip reached the maximum.
精神性出汗对于使握力顺畅起着重要作用。本研究聚焦于汗液分泌的时间，探讨了精神性出汗与握力之间的关系。五名学生被要求尽可能用力地握住一个软球（直径9厘米）。在他们开始握球前5秒至握球后5秒收集皮肤电反应和出汗反应。结果显示，皮肤电反应在握球开始前1秒增加，而出汗反应在握球开始后1秒出现。这些结果表明，握力表现中的出汗反应呈现出与皮肤电反应不同的反应模式。握力达到最大值所需的准备过程可能在表现前诱发皮肤电反应，并且随着握力强度达到最大值，这一过程促进了汗液分泌。
