目的：探討太極拳訓練對於本體感覺 (觸覺敏度與力量本體感覺) 與肌力表現 (等速肌力與爆發力)之影響。方法：32 位健康大專學生分為：太極組 16 人與無訓練太極拳之控制組16人，進行為期 8週、每週3 次的樁式、單招與組合太極拳訓練。訓練前後分別進行：兩點覺閾針觸測試右腳中足觸覺敏度；以Biodex 等速肌力儀測試股四頭肌力量本體感覺能力及等速肌力；利用測力板評估垂直跳躍高度表現。統計分析：以相依樣本t 檢定考驗各組內訓練前後差異，以獨立樣本t 檢定考驗兩組間進步率差異，顯著水準定為 α = .05。結果：經 8週太極拳訓練後，太極組在觸覺敏度(p = .019)及力量本體感覺(p = .024) 前後測達顯著進步，且力量本體感覺進步率顯著優於控制組(p = .021)；而等速肌力、垂直跳躍表現，兩組間與組內均無顯著差異。結論：八週太極拳訓練可增進皮膚觸覺敏度，且能顯著提升力量本體感覺的準確性，但對於肌力與爆發力並無顯著影響。

Purpose: To investigate the training effects of Tai Chi Chuan on proprioceptive system (tactile acuity, strength adjustment) and muscular performance (isokinetic strength and power). Methods: Thirty-two young healthy participants were randomly assigned into Tai Chi group (8 males, 8 females) and control group without training (8 males, 8 females). Tai Chi group performed Wuji pylon stance, single-form, and combination training of Tai Chi Chuan three times per week for 8 weeks. Proprioceptive system and muscular performance were measured before and after training. Tactile acuity of middle foot of the dominant leg was measured by using a Lafayette instrument two-point aesthesiometer. Strength adjustment and isokinetic strength of the dominant leg knee extensor were assessed by a Biodex isokinetic dynamometer. Vertical jumps was measured by using an AMTI force plate. The paired t-test t was used to compare the difference between pre- and post-training, and the independent t-test was used to compare the difference of the changing rate between two groups. The α level was set at .05. Results: After 8 weeks of Tai Chi Chuan training, the Tai Chi group significantly improved tactile acuity and strength adjustment (p < .05). The changing rate of strength adjustment in the Tai Chi group was significantly better than the control group (p < .05). However, the isokinetic strength of knee extension and vertical jump showed no significant difference between pre- post-training and groups. Conclusion: An eight-week Tai Chi Chuan training program improves tactile acuity and force sense but in muscular strength and power.
