The subjectswere 21 younger boys (4.8±0.2 years), 22 elder boys (5.8±0.3 years) and 20 healthy male adults (21.2±1.2 years). In the young children?s 25 m and adult?s 50 m sprint, the sections 0 to 15 m and 0 to 30 m,respectively, were defined as the acceleration phase of, and 15 to 25 and 30 to 50 m, respectively, as themaximum speed phase to examine the time (seconds), step frequency (step/second) and length (m/step) inthe two phases. Result showed that the running speed and step length of elder boys were significantlylarger than those of younger boys, without significant differences in step frequency between the two groups(p<0.05). In all groups, the running speed and step length in the maximum speed phase were significantlylarger than those in the acceleration phase, and the step frequency was significantly smaller (p<0.05). Theyoung children?s height showed moderate correlation (r = 0.514 ? 0.608) with the running speed and steplength in the two phases, but no correlation with the step frequency was found. There was a strong positivecorrelation (r = 0.606 ? 0.862) between the running speed and step length in all groups, but no correlationwas found between the running speed and step frequency. From these results it was concluded that, like foradults, the faster the running speed in acceleration phase in young childhood, the higher the running speedin the maximum speed phase and, furthermore, the running speeds of young children in the accelerationand maximum speed phases are determined by the increase in step length accompanying the increase inheight.キーワード：幼児，疾走速度，ピッチ，ストライドKeywords：young children, maximal running speed, step frequency, step length1）岐阜聖徳学園大学教育学部体育専修〒501-6194岐阜市柳津町高桑西1-12）岐阜聖徳学園大学短期大学部〒500-8288岐阜市中鶉1-383）岐阜大学教育学部保健体育講座〒501-1193岐阜市柳戸1-14）名古屋市立楠小学校〒462-0005名古屋市北区池花町309番地1）Department of Physical Education, Faculty of Education, GifuShotoku Gakuen University1-1, Takakuwa-nishi, Yanaizu-cho, Gifu, Japan (501-6194)2）Junior College, Gifu Shotoku Gakuen University1-38, Nakauzura, Gifu, Japan (500-8288)3）Department of Physical Education, Faculty of Education, Gifu University1-1, Yanagido, Gifu, Japan (501-1193)4）Nagoya Municipal Kusunoki Elementary School309, Ikehana, Kita-ku, Nagoya, Japan (462-0005)? 333 ?
