摘要

目的：探討不同蹲舉姿勢與不同負重之膝關節力矩差異。方法：經由動作擷取系統與測力板蒐集12位大專男（年齡：20.91 ± 1.32歲，體重：70.83 ± 5.42 kg，身高：177.85 ± 3.92 cm）1/2及1/3蹲舉不同荷重過程之動力學及運動學參數。以重複量數二因子變異數進行分析，以Fisher's least significant difference（LSD）進行事後比較，顯著水準α = .05。結果：最大屈曲伸展力矩，1/2蹲舉為0.98 ± 0.15-2.19 ± 0.27 Nm/kg，1/3為蹲舉0.9 4± 0.19-2.23 ± 0.30 Nm/kg，蹲舉方式未達顯著差異，但較重負重有較大曲屈伸展力矩（p ＜ .05）。結論：兩種蹲舉姿勢適用於一般健康年輕族群；在內收外展與內外旋力矩方面，1/3方式會有較小的負荷，適合膝關節傷害復建與肌力較差之族群。

Purpose: To investigate the variation of different postures and loadings of barbell squats on knee joint force. Methods: The Vicon motion capture systems and Kistler force plate were used to acquire 12 male college students' (age 20.91 ± 1.32 yrs, weight 70.83 ± 5.42 kg, height 177.85 ± 3.92 cm) kinetic and kinematic data during 1/2 and 1/3 squats under different loadings. The selected variables were tested by two-way repeated ANOVA (α = .05) and post hoc comparisons by Fisher's least significant difference (LSD). Results: The maximal moment of flexion/extension were 0.98 ± 0.15- 2.19 ± 0.27 Nm/kg in 1/2 squats, and 0.938 ± 0.19-2.23 ± 0.295 Nm/kg in 1/3 squats. There was no significant difference between two types of barbell squats; nevertheless, flexion/extension moments of the knee joint were significantly greater for heavier loading than lighter loading. Conclusion: This research indicated that the two postures of loading are suitable for health young people; the 1/3 squat is more fit to knee injury and poor muscular fitness people, due to lower moments of knee adduction/ abduction and knee internal/external rotation.
