足部形态学特征与踝关节肌肉力量及运动能力的关系研究

Associations of Foot Morphological Characteristics with Ankle Muscle Strength and Exercise Performance

目的:探究足部形态学特征与踝关节肌肉力量及运动能力的关系。方法:选取65名成年男性作为研究对象,平均年龄(48.85±7.95)岁,平均身体质量指数(body mass index,BMI)为(26.66±3.62)kg/m~2。足部形态学特征使用三维足形态扫描仪进行测量与评价,踝关节肌肉力量(包括跖屈、背屈、内旋、外旋)使用多关节等速肌力测试仪进行测量与分析,受试者运动能力使用灵活性、跳跃能力、本体感受性测试项目进行测量与评价。结果:校正年龄和BMI后发现,足长度、宽度、围度和高度等形态学指标与踝关节跖屈、背屈、内旋和外旋肌肉力量显著相关(r=-0.27~0.57,P<0.05),但未发现拇外翻角度与踝关节肌肉力量指标显著相关;足长度、宽度和围度指标与灵活性和跳跃能力指标显著正相关(r=0.25~0.44,P<0.05),足弓高度指数与纵跳高度呈显著负相关(r=-0.29,P<0.05),所测足形态指标均与本体感受性指标不相关。结论:足长度、宽度、围度和高度与踝关节肌肉力量以及运动能力之间具有相关关系。

Objective:To explore the possible association of foot morphological characteristics with ankle muscle strength and exercise performance.Subjects:A total of 65 adult men with a mean age of(48.85±7.95)yrs,and body mass index(BMI)of(26.66±3.62)kg/m2 participated in the study.Foot morphological characteristics parameters were tested by a 3-dimensional foot scanner,and ankle strength which including plantarflexion,dorsalflexion,internal rotation,ex‐ternal rotation was measured with a dynamometer.Exercise performance items which including agility,force,and proprioception were also measured.Results:After adjusted age and BMI,it found that all the measured parameters of the length,width,girth,and height of the foot were correlated with the strength of plantarflexion,dorsiflexion,internal rotation,external rotation(r ranged from‒0.27 to 0.57;P<0.05),except for the angles of hallux valgus.Moreover,the pa‐rameters of the length,width,and girth of the foot were correlated significantly with vertical jump ability(r ranged from 0.25 to 0.44;P<0.05).It was also found that the arch height index was negatively correlated with vertical jump(r=‒0.29;P<0.05),but no associations were ob‐served between indicators of morphological characteristics and proprioception.Conclusions:These findings indicate the length,width,girth and height of the foot were correlated with ankle strength as well as exercise performance.
