This study aimed to examine age-related, interindividual, and right/left differences in anterior-posterior foot pressure ratio in 764 preschool children (364 boys and 400 girls) aged 3.5-6.5 years.
Subjects maintained an upright standing posture for 10 seconds on the Footview Clinic, an instrument designed to calculate the anterior-posterior foot pressure ratio. The ratio of anterior foot pressure in each subject's right and left feet was selected as a variable, and the mean of a 10 s measurement was used for analysis.
The ratio of anterior foot pressure was significantly larger in the right foot than in the left foot. With regard to age, the ratio of anterior foot pressure was significantly larger in children aged over 4.5 years than in children aged 3.5 years. It was also larger in children aged 6 and 6.5 years than in children aged 4 years. Interindividual differences in variables were large, and coefficients of variance were highest in children aged 3.5 years and lowest in children aged 6.5 years.
In conclusion, anterior foot pressure increases with age in preschool children. Interindividual differences in anterior foot pressure are large and tend to decrease with age. Furthermore, the anterior foot pressure is slightly higher in the right foot than in the left foot. These results will be useful for various studies, such as examining relationships between the anterior-posterior foot pressure ratio and factors, such as untouched toes, physical fitness, and level of exercise.
本研究旨在探讨 764 名 3.5-6.5 岁学龄前儿童（男 364 名，女 400 名）前后足压力比的年龄相关、个体间和左右差异。
受试者在 Footview Clinic 上保持直立站立姿势 10 秒，该仪器用于计算前后足压力比。选择每个受试者左右脚的前足压力比作为变量，使用 10 秒测量的平均值进行分析。
右脚的前足压力比明显大于左脚。就年龄而言，4.5 岁以上儿童的前足压力比明显大于 3.5 岁儿童。6 岁和 6.5 岁儿童的前足压力比也大于 4 岁儿童。变量的个体间差异较大，3.5 岁儿童的变异系数最高，6.5 岁儿童的变异系数最低。
总之，学龄前儿童的前足压力随年龄增长而增加。前足压力的个体间差异较大，且随年龄增长而减小。此外，右脚的前足压力略高于左脚。这些结果将对各种研究有用，例如研究前后足压力比与未触及脚趾、身体素质和运动水平等因素之间的关系。
