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.
