中文摘要 | 使用全身式震動訓練對於增進下肢的爆發力,已經有許多研究加以證實,但相同的震動刺激對於不同運動型態的運動員,是否具有相同的感受與效果,則尚未有研究探討。本研究試圖比較太極拳與舉重健美2種運動型態差異極大的運動員,對震動刺激的主觀感受與身體反應。本研究使用垂直震動儀器(Model VS 5060 LD, Vibration Source Inc., Taiwan),頻率為5、9、12、16、20、24 和30 Hz,震幅為4 mm,受試者一組為太極拳練習者(N=12),另一組為舉重健美選手(N=15)。結果顯示兩組受試者在主觀知覺努力程度上,除5和9 Hz沒有顯著差異外,其餘均達顯著差異。脛骨粗隆處加速度最大值在5、20和30 Hz;頭部加速度最大值在12、16和20 Hz達到顯著差異。傳遞比於脛骨粗隆處處在5、20和30 Hz;頭部在16和20 Hz達到顯著差異。經過討論分析,發現不同運動型態運動員對於震動刺激的感受明顯不同,此點可能和頭部加速度有關。脛骨粗隆處在16 Hz時的傳遞比達到最大。使用震動刺激訓練時,須參酌選手的運動特性與身體素質來訂定頻率與震幅。 |
英文摘要 | The whole body vibration (WBV) is a new technique which can improve leg muscle strength. Many researchers have studied the effects of whole body vibration recently. There has lacked studies on the effects of vibration stimulus on athletes different sports types, and their feelings. Two groups from tai-chi (N=12) and weight-lifting (N=15) served as subjects in this study. The subjects were asked to stand in a half-squat posture without additional load on a vibration platform (Model VS 5060 LD, Vibration Source Inc., Taiwan) for 7 frequencies (5, 9, 12, 16, 20, 24, 30 Hz) at 4 mm amplitude and maintain 30 seconds. Dactron Photon Ⅱ was used to collect four accelerometers' data on platforms, tibial tuberosities, shoulders and heads. The rating of perceived exertion (RPE) scale of Borg's 10 points was used to record the feel of subject at each frequency. The t-test was used to compare the independent variables between tai-chi and weight-lifting groups. The perceived exertion was significantly different between the weight-lifting and tai-chi groups at 12, 16 & 20, 24, 30 Hz (p<.05). The maximal acceleration of tibial tuberosity at 5, 20 and 30 Hz, and that of 12, 16 & 20 Hz at head were significantly different between the tai-chi and weight-lifting groups. The transmissibility at tibial tuberosity on 5, 20 & 30 Hz and that at head on 16 & 20 Hz were different significantly. The effects of WBV would be different on different sports athletes' perceived exertion that may be related to the acceleration of head. The transimissibility has a maximal value at tibial tuberosity on 16 Hz. When using the whole body vibration training to improve muscle power and strength, much depends on the athlete's sporting features and physical quality to decide the amplitude and frequency of whole body vibration. |
