Abstract

The purpose of the present study was to characterise the temporal regulation of a simple but natural movement, forearm throwing. Our finding is the time leg of wrist flexion throwing is less consistent than that ofdeviation throwing. Two experiments demonstrate two potential error factors involved in a simple throwing action. The result data demonstrated that there is a limit with which people can perform self-timing activities. The limit for best people could do in releasing two fingers is 6ms, 12ms for deviations throwing only, flexion throwing with finger releasing is about 18 ms, but was about 25ms in deviation throwing with finger releasing.
