과중량을 이용한 워밍업 점프가 사후 점프 수행에 미치는 영향

Purpose: The purpose of this study was to investigate the effects of loaded vertical jumps on the following vertical jumps and to find how long the transient effect of warm-ups would continue. Methods: Twelve healthy college male students, majoring in physical education, participated in this study voluntarily. They performed three sets of unloaded jumps (pre-jump, 5% post jump, and 10% post jump) and two sets of loaded jumps (5% and 10% loaded jumps) according to the counter-balanced order. At each set, three trials of maximal vertical jumps were performed by a 30 second interval between trials and a 3 minute break after warm-up jumps. Force platform and motion capturing system were used to record motions and ground reaction force. Results :Only 5% post-warm-up jumps (48.29±2.06 cm) showed significant increase in the jump height compared with pre-warm-up jumps (47.35±2.21 cm). The transient effects of loaded warm-ups disappeared 4 minutes after loaded jumps. Conclusion: Conclusively, a decent amount of loading (around 5% extra of body weight) during sport specific warm-ups would give a positive, transient effect on the performance of the vertical jump.

The purpose of this study was to investigate whether the kinesio-taping improves biomechanical performance (repetitions of the task and mechanical power) and muscular fatigue in muscular endurance exercises such as continuous vertical jump (a three set of 20 seconds), push-up (a three set of 30 seconds), and sit-up (a three set of 30 seconds) in a row. Six college students (mean±S.D.; 22.67±2.25 years, 171.5±4.08 cm, 67±9.91 kg) participated in this study at two different sessions over two weeks. The treatment of taping was applied to subjects according to the counter-balanced design in order to remove learning effect due to repeated measures of same tasks. High speed motion capturing system, force platforms, and wireless electromyography system were used to capture body marker motions, ground reaction forces, and muscle activities of major muscles. Due to insufficient number of subjects, the non-parmeteric test of Wilcoxon test was executed to test whether the taping induces improved athletic performance in muscular endurance exercises. Statistical results showed that the taping treatment improved repetitions of all three tasks (p<.05). However there was no statistical difference in mechanical powers and muscular activities in three muscular endurance exercises. Conclusively it was concluded that a kinesio-taping would be helpful to improve athletic performance of repetitions as of result of different proprioceptive function not as a result of improved fatigue resistance.
