Kinematic Analysis of Free-Style Stroke Movement

-A Consideration about Relevance with a Form Simulated in Land Air Space and a Shoulder Injury-

Abstract

We used a 3-dimensional motion analysis system to analyze a free-style swimming form simulated on land in air space and investigated its relevance to shoulder injury in 12 male competitive swimmers. In the hand entry and mid recovery of free-style stroke, a difference was been between the form of the group with breathing on the same side as the shoulder injury and the group with breathing on the side opposite to shoulder injury, suggesting a relationship between breathing side and shoulder injury. It is thought that we can interpret the results of this study more concretely in the future by analyzing swimmers' form in the water.
