Amplitude and phase response of ventilation (V_E), carbon dioxide output (VCO_2) and oxygen uptake (VO_2) during sinusoidally varying work load for periods (T) of 1〜16 min were studied in six healthy men. The relationships between these parameters and aerobic capacity (VO_2max, ATVO_2) were also examined.The results and conclusions obtained were as follows : (1)The relationship between the period (T) of exercise and amplitude response of VO_2,VCO_2 and V_E was well described by first-order exponential models.However,the relationship between the period of exercise and the phase shift (phase responses of VO_2,VCO_2,and V_E) was better described by complex models comprising a first-order exponential function and a linear equation.This can be explained by Karpman's threshold theory.(2)High negative correlations were observed between the steady-state amplitude (A) of phase response or the time constants (〓) of amplitude response and VO_2max,and ATVO_2.Significantly high negative correlations for all gas exchange parameters may be more rapid in individuals with greater aerobic capacity.(3)A close relationship between the response of VCO_2 and V_E was demonstrated by a higher correlation coefficient than that between VO_2 and VCO_2 or between VO_2 and V_E.This call be partly,but not completely,explained by the cardiodynamic theory.
