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 less than 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 less than 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).

摘要

为了研究二氧化碳敏感性的季节变化，全年对10名健康男性测定了对二氧化碳通气反应的斜率（S）。结果发现，9月份对数S的平均值显著高于年平均值（p<0.05），尽管S的平均幅度没有显著差异。此外，1月份对应于动脉血二氧化碳分压（PACO2）60 mmHg时的平均通气量（VE[60]）显著低于9月份（p<0.05）。这些结果表明，训练开始和/或结束的时间是体育训练对S和VE[60]产生影响的一个重要因素。
