Comparison Between the Left and Right Shoulder Range of Motion During a Supine Dumbbell Fly Press
Arts and Sciences
The purpose of this study was to compare the range of motion in the right and left shoulders, while performing a supine dumbbell fly press. Hypothesis one stated there would be a significant difference in the range of motion in the right and left shoulder. Participants included 13 (M=8; F=5) traditional college aged students who did not have current shoulder injuries. Data consisted of video recording a supine dumbbell fly press. Analysis of shoulder range of motion was completed on Dartfish Human Motion Analysis. A paired sample t-test indicated no statistically significance difference in right and left shoulder range of motion with p= 0.511. The hypothesis is therefore rejected. The second hypothesis was there would be a significant difference in the torque between right and left shoulders. A paired sample t-test indicated a significant difference in the right and left shoulder torque with p = 0.045. Hypothesis two is accepted. While range of motion may not be significantly different between right and left shoulders while performing the supine dumbbell fly press, a significant difference in torque at the shoulder is present.
