單側與雙側壺鈴訓練對跆拳道品勢選手平衡能力及核心穩定之影響
Effects of Bilateral and Unilateral Kettlebell Training on Balance Ability and Core Stability in Taekwondo Poomsae Athletes
摘要
本研究目的在探討6週單側或雙側壺鈴訓練對跆拳道品勢選手平衡能力及核心肌群穩定能力之影響。研究招募26名跆拳道品勢選手，以鶴立進行平衡能力測試成績配對分為單側組（13人）或雙側組（13人），受試者除了正常接受品勢訓練外，額外進行每週2次、每次1 hr，持續6週單側或雙側壺鈴訓練（每次訓練4個動作、共3組）。訓練前、後均測量受試者之壓力中心（center of pressure, COP）偏移範圍及速度與軀幹伸直、軀幹屈曲及左、右側棒式等核心穩定能力。研究結果顯示：單側組、雙側組二組之慣用腳及非慣用腳側向COP偏移速度與軀幹伸直、軀幹屈曲動作持續時間皆顯著優於未訓練前測量值。單側組之慣用腳及非慣用腳側向及縱向COP偏移範圍與右側棒式動作持續時間皆顯著低於前測，雙側組之非慣用腳側向COP偏移範圍顯著低於前測。然而，二組間皆無顯著差異。本研究結論為持續6週、單側或雙側壺鈴訓練（每週2次、每次3組4個動作）皆能改善跆拳道品勢選手的平衡能力與核心穩定能力。

The purpose of this study was to investigate the effects of 6-week bilateral (BI) or unilateral (UNI) kettlebell training on the balance ability and core stability in taekwondo athletes. Twenty-six taekwondo poomsae athletes were recruited into UNI (n = 13) or BI (n = 13) groups with a matched-pair of performing balance in hakdariseogi. All participants sustained the regular taekwondo poomsae training programs during the experimental period and had additional kettlebell training (4 movements for 3 sets) twice per week for 6 weeks. The radius and velocity of center of pressure (COP), the core stability test of isometric trunk extensor and flexor as well as abilities of right and left side plank were tested before and after the experiment. The results showed that the COP velocities for mediolateral displacement of dominant and non-dominant legs, as well as holding time of isometric trunk extensor and flexor exercise in both UNI and BI groups were significantly better after 6-week training than those of pre-training. The UNI group after training showed significant improvements in COP range for mediolateral and anterior-posterior displacements of both legs, as well as holding time of right side plank compared to pre-training. Moreover, COP range for mediolateral displacement of the non-dominant leg was significantly lower than pre-training in BI group. Nevertheless, there were no significant differences between the groups. We conclude that the UNI and BI kettlebell training twice per week for 6 weeks can improve the balance ability and core stability for taekwondo poomsae athletes. Moreover, there was no significant difference between UNI and BI kettlebell training.
