50名1至35岁的男性和女性。在运动过程中研究了年龄的变化。在最初的几个月里，步行的频率与步行的速度没有明显的关系。对数-对数回归方程比线性方程更好地描述了成年人的关系。少数青少年更好地描述了一个线性方程和双对数或线性方程可用于儿童。5年后，最大步频与身高平方根的乘积近似恒定。年龄。摆动时间最初显示出与一条腿的完整循环时间的正回归。儿童放弃了这种模式，赞成一个近似恒定的时间摆动和4-5岁的负线性回归成人出现。摆动的时间通常远小于整个腿绕臀部或小腿和脚绕膝盖的自然周期的一半。研究了穿鞋对步频和摆动时间的影响。
Fifty males and females between 1 and 35 yr. of age were studied during locomotion. During the first few months of walking the step frequency bears no apparent relationship to the speed of walking. A log-log regression equation describes the adult relationship better than a linear equation. A few adolescents were better described by a linear equation and either log-log or linear equations can be used for children. The product of maximum step frequency and the square root of the stature is approximately constant after 5 yr. of age. The time of swing initially shows a positive regression with the time for a complete cycle of one leg. The child abandons this pattern in favour of an approximately constant time of swing and by 4-5 years of age the negative linear regression of the adult appears. The time of swing is usually much less than half the natural period of either the whole leg about the hip or of the lower leg and foot about the knee. The effects of wearing shoes upon step frequency and time of swing were investigated.
