The length of stride-frequency during with different speeds was investigated on 16 athletes of the track and field. The speed, lengh of stride and stride frequency during 1500, 3000, and 5000 meter runs at full speed was investigated on 6 distance runners, too. At the same time, the muscular strength of leg and the maximal bicycling time was measured. The results were as follows: 1. At the speed up to 6m/sec. all subjects increase their speed mainly by increasing length of stride. At the greatest speeds, they show the maximum stride-frequency, but decrease length of stride, 2. Fig. 3shows that the area is made of two intersections of (length of stride/ maximum length of stride) line and (stride-frequency/maximum stride-pre-quency) line. The area of higher speed subjects are bigger than that of rower speed subjects, 3. The speed during 1500, 3000, and 5000 meter runs at full speed have significantly high correlations to the length of stride with the coefficient of r=0,737, r=0.966, r=0.817.
