The subjects were five male race-walkers (race-walker group) and five male college students (control group). The results obtained were as follows : 1.Under race-walk conditions,the highest speeds attained in the race-walker and control groups were 200〜220 m/min and　160m/rnin, respectively. Under normal walking conditions, however, the values were 140 m/nlin in both groups. 2.A lower oxygen requirement was observed at slower speed during normal walking and at a higher speed(over 130 m/min) during race-walking. 3.Oxygen requirement(ml/kg/100 m) in the race-walker group was minimal at 60〜80 m/min during race-walking and at 60 m/min during normal walking.Values in the control group were minimal at 60 m/min under both walking conditions. 4.The oxygen requirement in the race-walker group was less than that of the control group under both walking conditions. 5.Under normal walking conditions,as the speed increased,both step-length and step frequency gradually increased,until step-length reached a limit of 80 cm. Thereafter, walking was maintained only by an increase in step frequency.However,in the race-walkes group,the subjects were capable of increasing their step-length further,and maintaining a higher speed(up to 220m/min). 6.It was suggested that race-walking is one of the most efficient exercises for maintaining and improving health.
