The relationships between running performances (200 m running time and 5-min run) and V^^・O_2max, Lactate Threshold (LT), or percent fat were investigated on 11-12-year old boys. Subjects were 21 control boys (group C) and 21 soccer boys (group S). Mean 200 m running time in group S was significantly better than that in group C. Mean distance of 5-min run in group S was significantly longer than that in group C. No significant difference was found between mean running speed of 5-min run and mean speed at exhaustion in LT experiment. In group C, 200 m running time correlated significantly with V^^・O_2max. In group S, faster runners showed higher peak post 200 m run lactate concentration. 5-min run correlated significantly with V^^・O_2max for group C, group S and all subjects combined. LT correlated significantly with 200 m running time and 5-min run. No significant relation was found between running performances and percent fat. It is suggested that V^^・O_2max and LT determine, in part, boy's running performances, but percent fat do not.
