説明
This study aimed to clarify the 3-dimensional joint kinetics of the takeoff leg for the single-leg rebound jump (SRJ) and the double-leg rebound jump (DRJ). 14 male track and field athletes (sprinters, jumpers and decathletes) performed the SRJ and the DRJ with maximal effort. Kinematics and kinetics data were recorded using a Vicon T20 system (250 Hz) and force platforms (1000 Hz). The results of all the analyses were as follows:<br> 1. In the SRJ, hip joint work around the adduction-abduction and internal-external rotation axes was higher than in the DRJ, because of larger hip abduction and internal rotational torque in the SRJ.<br> 2. In the SRJ, hip abduction and internal rotation torque were larger than those in the DRJ. These may have been caused by the anatomical and mechanical differences between the SRJ and DRJ.<br> 3. In the SRJ, hip abduction torque affected the increment in jump height. This result suggests that hip abduction torque affects the higher jump height for a single leg to a greater extent in the SRJ than in the DRJ.<br> 4. In the SRJ, the trunk lateral flexion caused by trunk flexion torque reduced the lateral displacement of the center of gravity due to pelvic list.<br> These results suggest that 1) the SRJ is an effective training tool for improvement of technique and force output ability for prioritization of power output at the hip internal rotators, especially the hip abductors in addition to the hip extensor, and 2) hip abduction torque in the SRJ has a role in both postural control and determining the increment in jump height. These findings will be useful for clarifying the most pertinent points related to the SRJ and for developing an effective method that can be applied to plyometrics.<br>
