抄録: The present study was intended to investigate the work capacity of the athletes (mid die- and long-distance runners) in comparison with the sedentary persons from the view point of respiratory functions. The work was given to the subjects on a bicycle ergometer with the progressively increasing load up to nearly the maximal level V^^・_<O_2>. V^^・_E, V_T and D_<LCO> were determined during submaximal and maximal work on non-athletes and athletes. To determine pulmonary diffusing capacity(D_<LCO>), Filley's steady state method was used. The subjects were 10 ordinary healthy males (aged 29〜32years), and 6 trained middl- and long-distance runners (aged 20〜25 years). The results obtained in this study were as follows; 1) V^^・_<O_2> for non-athletes was always greater than that for athletes at the same work intensity. The mean value of maximal oxygen uptake for athletes was significantly greater than that for non-athletes. 2) Pulmonary ventilation (V^^・_E), respiratory rate (RR) and tidal volume (V_T) for non-athletes were always greater than those for athletes at the same V^^・_<O_2> In otherwords, respiratory efficiency for athletes was higher than that for non-athletes. 3) Pulmonary diffusing capacity (D_<Lco>) for athletes was always larger than that for non-athletes at the same work intensity.
