Wearing Rubber Bands on Hands Improves Shoulder Function of High School Baseball Players

Abstract

This study investigated the effect on shoulder function of baseball players wearing rubber bands on their hands. The study enrolled 38 high school baseball players. The results showed a significant increase in the range of motion (left shoulder extension, right shoulder extension, and left shoulder joint maximum elevation value) following their wearing rubber bands on their hands. Furthermore, ease of movement showed significant increase in shoulder joint mobility after wearing rubber bands. These findings suggest that wearing rubber bands may improve baseball players’ shoulder function and mobility.
