[Sweating just before the beginning of handgrip performance].
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.
