Abstract

In order to examine the seasonal variation of CO2 sensitivity, the slope (S) of the ventilatory response to CO2 was determined in 10 healthy males throughout a year. It was found that the average value of logarithm S was significantly (p<0.05) higher in the September than in the annual average, though average magnitude of S was not significantly different. In addition, the average value of ventilation (VE(60)) corresponding of PACO2 60 mmHg was significantly (p<0.05) lower in January than in September. These results indicate that the timing of the start and/or finish of training is an important factor in the effect of physical training on the S and VE(60). Verf.-Referat
