Professor, Sport Biomechanics, Bu Ali Sina University, Hamedan, Iran. Previous studies have analyzed both kinematics and kinetic aspects of direct punch to a boxing bag (2-4). The purpose of this study was to compare the shoulder range of motion during shadow punch and boxing bag punch in amateur boxers. Mean and standard deviation of shoulder flexion, abduction and internal rotation during punch CONCLUSION The results of present study showed that punching for a virtual target, such as in shadow boxing condition, amateur boxers displayed larger shoulder flexion in the attacking arm compared to the boxing bag kick. In conclusion, shadow kick differs from the boxing bag punch."

range of motion of shoulder including abduction, flexion‌, and axial rotation were measured. Paired sample t-test was used for statistical analysis. The significance level was set‌ at‌ p<‌;0/05.

RESULTS

The shoulder range of motion is illustrated in figure‌ 1. The‌ range of shoulder flexion on attacking arm was different between the two techniques (p=0/03). Shoulder abduction‌ and‌ rotation‌ was similar in the two techniques (P>0.05).

abduction and internal rotation during punch

CONCLUSION

The results of present study‌ showed‌ that‌ punching for a virtual target, such as in shadow boxing condition, amateur boxers displayed larger‌ shoulder‌ flexion in the attacking arm compared to the boxing bag kick. Based on‌ Previous‌ studies‌ Karateka presented higher shoulder and elbow angular velocity during punch against makiwara (1). We did‌ not‌ find any similar study to compare our results. In punch against punching bag‌ antagonistic‌ muscles‌ are learned to control the shoulder motion to prevent the extreme range of motion for‌ security‌ reasons. However, other motions were similar in both techniques.

In conclusion, shadow‌ kick‌ differs‌ from the boxing bag punch. Consequently they may have

different muscle activation pattern.
