| 摘要: | 目的：探討 10 週下肢漸進式重量訓練與核心訓練對衰弱銀髮族功能性適能、步態與平衡的影響。方法：本研究招募 9 位 65 歲以上、符合走路速度緩慢或符合衰弱握力標準始為研究對象，隨後進行 10 週下肢漸進式重量訓練 (臥姿腿部彎曲機、臀部訓練機、坐姿大腿推蹬機及髖部外展訓練機，以 60 % 1RM、強度漸進) 與核心訓練 (橋式、死蟲式、屈膝捲腹及分段旋轉，強度漸進)，分別在訓練介入前後評估功能性適能、步態與平衡。因受試者樣本數較少，所得資料使用無母數分析魏可遜配對組符號等級檢定法 (Wilcoxon matched-pairs signed-rank test) 比較各實驗參數之間在介入前後之差異，其考驗顯著水準設定為 α＝0.05。結果：以下實驗參數在訓練介入後相較於介入前皆顯著進步：功能性適能方面有30秒坐姿起立測驗 (15.6 ± 3.8 vs. 18.0 ± 5.1次, p =0.041)、手臂彎舉 (16.0 ± 3.2 vs. 19.9 ± 5.1次, p=0.012) 及8英呎起身繞行 (6.84 ± 1.51 vs 5.88 ± 1.16秒, p=0.018)；在平衡測驗上有開眼平衡左腳壓力中心的前後方向偏移 (2.64 ± 1.35 vs 1.82 ± 0.61, p=0.015)，右腳壓力中心的前後方向偏移 (2.37 ± 1.19 vs 1.85 ± 0.78公分,p=0.083)；在步態方面僅有右腳的最大角速度 (378.68 ± 21.99 vs 400.50 ± 22.73/秒,p=0.083)。結論：下肢重量訓練與核心訓練結合可以改善老年人的功能性適能、平衡與步態能力，未來可以提供給銀髮俱樂部實務訓練參考。
Purpose: To investigate the effect of 10-week progressive lower extremity resistance training and core training on functional fitness, balance and gait of frail elderly. Methods: This study recruited 9 subjects over 65 years old who met a criterion of slow walking speed or weak grip strength. Ten weeks of progressive lower limb resistance training and core training was performed. The functional physical fitness, balance and gait were evaluated before and after the training intervention. The data obtained before and after training were tested using Wilcoxon tests of nonparametric analyses. The level of statistical significance was set at α = 0.05. Results: The following experimental parameters were significantly improved after the training intervention compared to before the intervention: the 30-second chair stand (15.6±3.8 vs. 18.0±5.1 times, p =0.041), arm curl (16.0±3.2 vs. 19.9±5.1 times, p=0.012), 8-ft up-and-go (6.84±1.51 vs 5.88±1.16 seconds, p=0.018) in the functional physical fitness; anterior and posterior direction shift of left foot with eyes open (2.64 ± 1.35 vs 1.82 ± 0.61, p=0.015), anterior and posterior direction shift of right foot with eyes open (2.37 ± 1.19 vs 1.85 ± 0.78,p=0.083) in the balance test; maximum foot speed of the right foot (378.68 ± 21.99 vs 400.50 ± 22.73,p=0.083) in gait. Conclusion: Lower body training combined with core training can bring great benefits for functional fitness, balance and gait in older adults. |
