An Electromyographical Analysis of Purposive Muscle Activity and Appearance of Muscle Silent Period in Archery Shooting

Abstract

Shooting an arrow is a typical example of the physiological neck reflex. To get a good record in the archery competition, highly reproducible release is required during the drawing of a bow. In this study, first, the mechanics of shooting were analysed by means of EMG, progressive photographing and bow strain signals, employing two groups of college student archers (semi-skilled and unskilled). These results were compared with those of the world top-class archers. And second, the rate of muscle silent period appearance, its latent time and release reaction time were measured from the three groups of college student archers (skilled, semi-skilled and unskilled). The following results were obtained. © 1984, The Japanese Society of Physical Fitness and Sports Medicine. All rights reserved.
