The purpose of this study was to determine whether or not there were differences in hip motion in the forward and backward giant on the uneven parallel bars. Our results suggest that there were indeed differences in the hip motion in the two movements. These differences were seen in the hip joint angles. The peak flexion in the forward giant was smaller than the peak flexion in the backward giant, and occured at an earlier time in the forward giant. Peak extension was also smaller in the forward giant than in the backward giant, however the peak extension occured later in the forward giant than in the backward giant. Although the hip joint is not generally thought of as an important joint in the giant swing, its motion was the key to successful completion of the forward and backward giant. Researchers Boyd, Peirce and Batt agreed: "As a major weight-bearing joint, normal hip function is fundamental to successful sporting participation. Not only is it important in running-, jumping- and kicking-based activities, it also contributes to the generation and transference of forces in upper limb-dominated activities." In a study of collegiate soccer players, hip inflexibility and strength were determining factors in the susceptibility of injuring the lower extremity (Agre and Baxter, 1987). Conversely, in our study, hip inflexibility would not cause injury, but would inhibit successful completion of the movement. Our study was limited because our subject pool contained only one individual. Hip differences in forward and backward giants may be studied more thouroughly if a larger number of subjects were used. We may have found that the differences occured at different times and at different angles in other subjects. Studying the hip biomechanics on the "upswing" portion of the giant swing may also have altered our results. Hip differences may also be analyzed in a cross-gender study.
