The purpose of the study was to examine how preliminary muscular tension affected reaction time and movement accuracy. The main dependent variables were reaction time and movement accuracy. Movement accuracy was measured by absolute movement error. Also simple and choice conditions were employed to identify the effect on task complexity at a performance level with preload being varied between Okg-16kg.

The results showed that the shortest reaction time was the medial range of muscular tension. The movement accuracy gradually decreased as the tension level increased. Choice conditions demonstrated longer reaction time and more variability than those of simple conditions.
