説明

Infant of muscle strength and skeleton have not enough provided stimulus which become a factor for defective bone formulation of feet as the results induced podiatric problems. In this study, we focused on lower limb muscle strength in children. We developed quantitative, easy-to-use measurement devices for assessing toe-gap force and knee-gap force in children. The aim of this study was to examine the following 3 factors: (1) to examine the efficiency of measurement devices by using a field test; (2) to examine the basis of development process on lower limb muscle strength in infants; and (3) to examine the effect of habitual exercise on lower limb muscle strength development. The study subjects consisted of 579 kindergartners aged between 3 and 6 years. In all subjects, toe-gap force and knee-gap force were measured using measurement devices, and development of age related was indicated by both measurement methods. It is supposed a threshold as 0.4 kgf of toe-gap force in three to four years old, as 0.6 kgf in five years old, as 0.8 kgf in six years old. Especially, children who were not enough developed found on toe-gap force in the experiment. Age-related development was found to increase knee-gap force in children (4 kgf in 3-year-olds, 5 kgf in 4-year-olds, and 6 kgf in 5-and 6-year-olds, at the peak of frequency distribution). It is supposed a threshold as 2 kgf of knee gap force in three, as 3 kgf in four years old, as 4 kgf in five years old, as 5 kgf in six years old. Habitual exercise was found to improve toe-gap force in 6-year-olds; children who exercised regularly showed 1.4-times higher improvement in toe-gap force than those who did not exercise regularly. It is suggested that habitual exercise increases toe-gap force in children.
