CINEMATOGRAPHIC ANALYSIS OF THE KIP ON THE HIGH BAR

Le résumé fourni par la source

One skilled and eight unskilled subjects were selected as subjects in this study. They performed the kip on the high bar. The cinematographic analysis was undertaken to determine the characteristic results of the kip in the skilled and the unskilled. The following positions were defined for the phasic analysis : (A) end of back swing, (B) greater trochanter below the bar, (C) initiation of hip flexion, (D) end of forward swing, (E) initiation of hip extension, (F) greater trochanter below the bar, (G) greater trochanter at level of the bar, and (H) finish. The skilled completed the whole kip movements. However, the unskilled subjects could not carry their bodies to rise to the support position. In the skilled, the ankles were lifted to the bar. The unskilled lifted the knees, instead of the ankles, to the bar. Earlier bringing the legs up to the bar was observed in the unskilled than in the skilled. The skilled performer moved his body with the straight arms over the whole kip. The unskilled, however, lifted their bodies to the bar by bending the elbow joints during from the point (B) to the (F). The extension of the hip, or bringing the legs up for the kip, were started earlier in the unskilled subjects than in the skilled.
