The purpose of this study is to investigate and compare the acute effects of isolytic and static stretching training in individuals having subacromial impingement syndrome with glenohumeral internal rotation deficit. Isolytic group will receive isolytic stretching in modified cross body position. Static group will receive static stretching in modified cross body position. Stretching groups will be evaluated before and just after stretching exercise. Control group will receive no stretching. Control group will be evaluated for the first time and then will be waited until the duration of the stretching exercise program. Afterwards, second evaluation will be performed
