探討動態熱身結合全身振動在休閒運動女性肌肉力量及爆發力表現的差異
The effects of a single session of dynamic warm-up combined with whole-body vibration on the exercise performance of recreational female athletes
摘要
目的：動態熱身（dynamic warm-up，DW）與全身振動（whole-body vibration，WBV）已被認為有利於人體神經活化以及肌肉力量與爆發力的急性提升。然而，尚未有研究比較DW結合WBV對休閒運動女性運動表現之差異。本研究目的旨在探討比較DW結合WBV介入對休閒運動女性之運動表現之差異。方法：參與者為15名休閒運動女性（年齡22.7±1.2歲、身高161.9±6.3公分、體重54.6±8.1公斤、身體質量指數20.7±2.5（kg/m2）），採平衡次序進行三種實驗處理，區分為DW後立即（DW-0）、DW+WBV後立即（DW+WBV-0）及DW+WBV後10分鐘（DW+WBV-10）三種。進行反向跳（counter movement jump，CMJ）、落下跳（drop jump，DJ）與角速度60°及180°之下肢等速肌力測試。振動平台參數為垂直振動，振頻30Hz，振幅1.9mm。DW動作計有抬腿抱膝、抬腿跳躍、後勾腿、左右側交叉步、深蹲等五個動作。所得資料以單因子重複量數分析，採LSD法比較三種實驗處理之差異，α=.05。結果：在DW+WBV-10觀察到DJ的反應力量指數（p=.014）與著地時間（p=.011）、角速度60°與180°等速肌力之力矩峰值（p=.03；p=.016）與總做功（p=s.008；p=.008）皆顯著優於DW+WBV-0和DW-0。CMJ與DJ跳躍高度在三種實驗處理中未發現明顯差異。結論：DW結合WBV能有效提高休閒運動女性之下肢肌肉力量與牽張縮短循環能力。

Purposes: Dynamic warm-up (DW) and whole-body vibration (WBV) have been suggested to acutely enhance neural activation, muscle strength, and power in the human body. However, there is a lack of research investigating the effects of a single session of DW combined with WBV on the exercise performance of recreational female exercisers. The aim of this study was to examine the effects of a single session of DW combined with WBV on the exercise performance of recreational female exercisers. Methods: Fifteen recreational female exercisers (age: 22.7 ± 1.2 years, height: 161.9 ± 6.3 cm, weight: 54.6 ± 8.1 kg, body mass index: 20.7±2.5 kg / m2) participated in this study. Three experimental conditions, including DW immediately followed by WBV (DW + WBV - 0), DW followed by a 10 - minute rest and WBV (DW + WBV - 10), and DW alone (DW - 0), were administered in a balanced order. The exercise performance measures included counter movement jump (CMJ), drop jump (DJ), and isokinetic muscle strength tests at angular velocities of 60° and 180°. The WBV platform parameters were vertical vibration, with a frequency of 30Hz and amplitude of 1.9mm. The DW protocol included five movements: high knee lift, high knee skip, butt kick, carioca drill, and squats. The data were analyzed using one-way repeated measures analysis of variance (ANOVA), with LSD post-hoc comparisons. The significance level was set at α = .05. Results: The results showed significant improvements in DJ reactive strength index (p = .014), DJ ground contact time (p = .011), isokinetic muscle strength peak torque at 60° (p = .03) and 180° (p = .016), and total work at 60° (p = .008) and 180° (p = .008) in the DW + WBV - 10 condition compared to the DW + WBV - 0 and DW - 0 conditions. However, no significant changes were found in CMJ and DJ jump heights across the three experimental conditions. Conclusions: These findings suggest that the combination of DW and WBV effectively enhances lower limb muscle strength and stretch-shortening cycle capacity in recreational female athletes. Further research is warranted to explore the long-term effects and potential applications of DW combined with WBV in this population.
