    摘要:

    目的:探究坐姿及站姿下的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,为预测运动能力并预防足部损伤提供依据。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%足长处的足背高度、跖趾关节屈肌力量、第一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BMI后: 1)坐姿和站姿下的截脚长以及站姿下的足宽与第一足趾屈曲力量呈正相关;2)坐姿和站姿下的足长、足宽、截脚长与其余四趾屈曲力量成正相关,坐姿下的足弓高度指数与其余四趾屈曲力量成负相关;3)坐姿和站姿下的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。此外,在进行足部形态测量时因考虑不同姿态下的足部形态特征差异,为预测下肢特别是足部肌力,预防足部损伤提供参考依据。

    Abstract:

    Purpose: To explore the correlation among foot morphology and toe /metatarsophalangeal joint muscle strength to predict movement performance and reduce/prevent foot injuries. Methods: 26 male recreational runners were recruited. Foot length, truncated foot length, foot width, navicular height, dorsum of foot height at 50% the foot length, metatarsophalangeal joint strength, tensile force of the first , and remaining four toesand were measured by using Sylvac digital caliper, metatarsophalangeal joint strength measuring instruct, and Ailitech-AFG500 dynameter respectively. Partial correlations were used to analyze correlation between parameters. Result: With adjusted age and BMI, 1) 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; 2) the foot length, foot width and truncated foot length were positively correlated to tensile force of the remaining four toes in both position, and arch height index in sitting position was negatively associated with tensile force of the remaining four toes; 3) the foot width was positively correlated to metatarsophalangeal joint strength in both position. Conclusion: The longer foot length, foot width, truncated foot length, and lower arch height in normal range might relate to greater foot muscle strength. The targeted training plan can be made to enhance physical performance, and predictive weak muscles can be trained to prevent foot injury.
