慣性式肌力訓練對排球動作表現之影響

Abstract

目的：探討不同轉動慣量之之自主最快訓練速度慣性式阻力訓練，對於排球功能性動作表現之影響。方法：26名男女乙組代表隊選手參與本研究，使用可調整轉動慣量之自製慣性式阻力訓練器材，給予各組別不同的轉動慣量進行訓練，並記錄三週與六週的動作表現測試結果，使用二因子重複量數變異數分析法比較不同轉動慣量間以及訓練前後的差異。結果：經訓練後，上肢訓練結果，在站立與助跑扣球球速的表現沒有明顯增加，而下肢訓練結果的立定跳遠、折返跑、單/雙手立定摸高與單/雙手住跑摸高等動作表現皆有明顯進步，在但不同轉動慣量組別間上、下肢皆無差異。結論：六週慣性式肌力訓練對於下肢訓練較能有效增加動作表現，而慣量大小並沒有影響訓練效果，因此，建議未來選擇從事慣性式阻力訓練時，訓練全程盡最大自主動作速度即可。Purpose: To examine the effect of different Moment of Inertia (MOI) resistances on volleyball functional movements. Methods: Twenty-six (male and female) volleyball players were recruited and arranged to different MOI groups for 6 weeks lower and upper limbs inertial resistance training. The performances of volleyball functional movement after 3 weeks and 6 weeks training were obtained. Two-way analysis of variance (mixed design) was processed. Significant level was set at =.05. Results: In upper limbs results, the performance of run-up and stand spike were not significantly improved after training. In lower limbs results, the performance of standing long jump, shuttle run, single / both hands standing reach and single / both hands run-up reach were all significantly improved after training. But there was no significant difference among groups. Conclusions: The 6 weeks inertia resistance training can effectively increase the performance of lower limbs in volleyball functional movements. And there was no significant difference among different MOIs. To earn the best training effect, we suggest MOI selection for training should based on the movement speed.
