DECREASE RANGE OF MOTION AND PROBLEM IN LEARNING OF A NEW SPORT SKILL DUE TO WEIGHT TRAINING IN WEIGHTLIFTERS

The aim of this study was to survey the relationship between decrease in range of motion and learning of a new sport skill in people who had experience of weight training. This research was conducted using pre-test, three acquisition test, retention test and transfer test, with two experimental (n=18 weightlifters) and controlgroups (n=20 non-weightlifters). Data was collected by universal gonimeter and American Alliance for Health Physical Education, Recreation and Dance (AHHPERD) overhand volleyball serve. All of participants had the same schedule program with 120 trials (40trials in 3 sessions). Date analysis showed t hat weightlifters shoulder’s range of motion was significantly (p<0.05) smaller than non-weightlifters. Although diversity of performance from pre-test to retention and transfer test did not indicated that weightlifters learned the skill which they practiced non-weightlifters learned volleyball serve. Therefore we could conclude that weightlifters haveworse performance than non-weightlifters in learning of a new sport skill.
