不同深蹲姿勢對下肢關節角度變化之影響

The Effect of Different Squat Patterns to Lower Limb Kinematic and Kinetic

目的：本研究旨在探討不同深蹲姿勢對下肢運動學（動作分析參數）之影響。方法：本實驗募集8名男性受試者（平均年齡為20歲，平均身高175.21公分，平均體重71.55公斤），透過三維動作分析系統比較人體在兩種深蹲姿勢（膝蓋超過腳尖、不超過腳尖）及三種踝關節外轉角度（0°、15°、30°）之動作要求下，下肢髖、膝、踝關節矢狀面角度之影響。本研究以二因子重複量數變異數分析進行統計分析，顯著水準定為α＝.05。結果：膝關節超過腳尖會產生較大的膝關節矢狀面角度變化，不同踝關節外轉角度不會影響下肢關節矢狀面角度變化。結論：下肢髖、膝、踝關節超過腳尖在矢狀面會產生較大的膝關節角度變化。

Purpose: The aim of this study was to investigate different kinds of squat positions to lower limb kinematics (motion analyzing parameters). Methods: This study recruited 8 male participants (mean age 20 years old, height 175.21cm, body mass 71.55 kg). Two kinds of squat position (knees over toes, knees behind toes) and differences of joint angles in sagittal plane regarding hip, knee, ankle under three kinds of ankle external rotation angle (0°、15°、30°) were investigated by using 3D motion analyzing system. The two-way repeated measurement ANOVA was carried out for statistical comparison with a significant level of α=.05. Results: When the knees are over toes while doing squat, it produced greater angle displacements on knee joint in sagittal plane. However, different ankle external rotation angle did not affect joint angles of lower limb in sagittal plane. Conclusions: Doing squats with knees over toes produces larger angle displacements on hip joint, knee joint and ankle in sagittal plane.
