Abstract:
Minimalist walking shoes have been shown to improve foot muscle size and strength in active adults, but not in our previous study involving children, which could relate to the more structured footwear used in our study. Hence, this study examined the effects of true minimalists on intrinsic foot muscle size and strength, foot arch integrity, and physical function among primary school children. After a baseline assessment, 30 primary school students aged between 9 and 12 were given a pair of minimalist shoes (minimalist index = 92%) as their regular school shoes for two school terms, followed by a re-assessment. Seventeen of the 30 participants in the minimalist group completed the study. Compared to the control group, the minimalist group showed significantly increased cross-sectional area of abductor hallucis (p = 0.047, Cohen\'s d = 0.57) and flexor digitorum brevis (p = 0.037, Cohen\'s d = 0.80), increased strength of the hallux (p = 0.015, Cohen\'s d = 0.76) and lesser toes (p = 0.014, Cohen\'s d = 0.66), greater arch height (p = 0.020, Cohen\'s d = 0.52) and standing long jump distance (p = 0.001, Cohen\'s d = 9.79). The control group exhibited improved standing long jump performance only (p = 0.020, Cohen\'s d = 10.70). Minimalist shoes worn daily to school promote intrinsic foot muscle size and strength, and improve foot arch integrity among primary school students.
摘要:
极简主义步行鞋已被证明可以改善活跃成年人的脚部肌肉大小和力量,但在我们之前涉及儿童的研究中没有,这可能与我们研究中使用的更结构化的鞋类有关。因此,这项研究检查了真正的极简主义者对内在足部肌肉大小和力量的影响,足弓完整性,和小学生的身体机能。在基线评估之后,30名年龄在9至12岁之间的小学生获得了一双极简主义鞋(极简主义指数=92%)作为他们的常规学校鞋,为期两个学期,然后是重新评估。极简主义小组的30名参与者中有17人完成了这项研究。与对照组相比,极简主义组显着增加外展肌的横截面积(p=0.047,科恩的d=0.57)和屈指短(p=0.037,科恩的d=0.80),Hallux(p=0.015,科恩的d=0.76)和较小的脚趾(p=0.014,科恩的d=0.66)的强度增加,较大的足弓高度(p=0.020,科恩的d=0.52)和立定跳远距离(p=0.001,科恩的d=9.79)。对照组仅表现出改善的立定跳远成绩(p=0.020,Cohen\'sd=10.70)。每天上学穿的极简主义鞋子可以促进内在的足部肌肉大小和力量,提高小学生足弓的完整性。
