The aim of this study was survey of relationship between decrease in range of motion with learning of a new sport skill in people who they had experience of weight training. This research was been by pre-test, three acquisition test, retention test and transfer test, with two group experimental (n=18 weightlifters) and control (n=20 non weightlifters). Data was collected by Universal Goniometer and AHHPERD overhand volley ball serve. All of participants did same schedule program with 120 trials (40 trials in 3 sessions). Date analysis was showed that weight lifters shoulder’s range of motion was significantly (p<0.05) less than control group. Also diversity of performance from pre-test to retention and transfer test not indicated that weight lifters learned skill which practiced it, whereas this result showed that non-weightlifters learned volleyball serve. So we could say that weight lifters worse performed than non-weight lifters in learning of a new sport skill.
