INTRODUCTION

Direct forward punch‌ at chest height is a basic and simplest skill in boxing. Beginners usually perform it in a slower manner compared to elite boxers (1). There are few different way of training this skill including‌ shadow‌ kick, kicking the boxing bag, and kicking a partner during a fight. Each of these training methods may activate different neuromuscular pathway resulting in a different muscle activity pattern. Previous studies have analyzed‌ both‌ kinematics and kinetic aspects of direct punch to a boxing bag (2-4). The differences between the above mentioned techniques on muscle activation and/or biomechanical characteristics are not well explained. The‌ purpose‌ of this study was to compare the shoulder range of motion during shadow punch and boxing bag punch in amateur boxers.

METHOD

Ten male amateur boxers participated in this‌ experiment‌. All‌ subjects were amateur and had‌ between‌ one‌ to three months of experience in boxing. Subjects were excluded if they reported a history of upper extremity injury. Each subject performed‌ six‌ shadow‌ punches and six punch against punching bag while‌ his‌ shoulder kinematics was being measured using a Vicon system with four cameras. There was a five minutes of rest between every‌ two‌ following‌ punches. The
