Acute Effects of Upper Extremity Static Stretching and Dynamic Warm-up Protocols on Range of Motion, Strength, and Power Output

TL;DRAbstract

INTRODUCTION: Overhead throwing athletes develop muscular and capsular tightness of the posterior shoulder and an altered arc of motion in their dominant shoulder due to repetitive overhead throwing. Stretching has been suggested as a way to improve soft tissue flexibility and reduce the risk of shoulder pathology associated with posterior shoulder tightness (PST). Baseball players commonly perform upper extremity acute static stretching exercises during warm-up to increase glenohumeral (GH) range of motion (ROM), prevent injury, and enhance performance. However, previous literature has demonstrated that acute static stretching may be detrimental to performance. The purpose of this study was (1) to compare upper extremity static stretching and dynamic warm-up protocols and (2) determine the most appropriate protocol to increase GH ROM, decrease PST, and maintain GH strength and power. <br><br>METHODS: Upper extremity static and dynamic protocols were compared in 15 healthy and physical
