| Popis: | The purpose of this study was to identify the ground reaction force and lower extremity joint kinetics during clean exercises performed with light and heavy loads. Thirteen male track and field athletes performed the clean exercises from 20 kg to one repetition maximum (1RM). Kinetic data were collected from recorded data using a Vicon motion system (250 Hz) and force platforms (1,000 Hz). The results of the analyses were as follows: (1) Ground reaction force and joint kinetics of hip and ankle were increased by increasing loads in clean exercises. (2) From light to heavy loads, we found relationships between ground reaction force and joint torque of hip in clean exercises. (3) In progressing from light to heavy loads, some subjects continued to involve the muscle group controlling the hip joint as the main power source, while others did not. The results indicate that clean exercises yield different individual characteristics for training. These results suggest that the clean exercise is effective for selectively the hip extensor in all loads. |
