摘　　要：目的探究坐姿及站姿下跑者足部形态与足趾屈曲力量和跖趾关节屈肌力量的相关性。方法选取26名男性跑者,采用数显游标卡尺、跖趾关节屈肌力量测试仪、屈曲力量计测量足长、截脚长、足宽、足舟骨高度、50%足长处足背高度、跖趾关节屈肌力量、第1和其余四趾屈曲力量。使用偏相关分析足部形态与足部肌力的相关性。结果校正年龄与身体质量指数(body mass index,BMI)后,坐姿和站姿下截脚长以及站姿下足宽与第1足趾屈曲力量呈正相关;坐姿和站姿下足长、足宽、截脚长与其余四趾屈曲力量成正相关,坐姿下足弓高度指数与其余四趾屈曲力量成负相关;坐姿和站姿下足宽与跖趾关节屈肌力量成正相关。结论更长的足长、足宽、截脚长以及正常范围内更低的足弓可能意味着更好的足趾肌力。在进行足部形态测量时,因考虑不同姿态下足部形态特征差异,为预测下肢特别是足部肌力以及预防足部损伤提供参考。Objective To explore the correlation between foot morphology and toe/metatarsophalangeal joint muscle strength. Methods Twenty-six male recreational runners were recruited. Foot length,truncated foot length,foot width,navicular height,dorsum height at 50% of the foot length,metatarsophalangeal joint strength,tensile force of the first and remaining four toes were measured by using digital caliper,metatarsophalangeal joint strength tester and dynameter,respectively. Partial correlations were used to analyze the correlation between foot morphology and foot muscle strength. Results With adjusted age and body mass index( BMI),the foot width in standing position and truncated foot length in sitting and standing position were positively correlated to tensile force of the first toe;the foot length,foot width and truncated foot length were positively correlated to tensile force of the remaining four toes in both positions,and the arch height index in sitting position was negatively associated with tensile force of the remaining four toes;the foot width was positively correlated to metatarsophalangeal joint strength in both positions. Conclusions The longer foot length,foot width,truncated foot length,and the lower arch height in normal range might be related to the larger foot muscle strength. The consideration of the differences in foot morphological characteristics in different positions during the measurement of foot morphology can provide references for predicting foot muscle strength and preventing foot injury.
