Exercise metabolic rate was established by indirect calorimetry in 18 healthy subjects. Each subject was tested every month for 1 year. Four variables demonstrated a circannual rhythm and its acrophases occurred in the following months: RQ in October; exercise metabolic rate in April; acceleration of heart rate during exercise in February; percentage of body fat in August.
通过间接测热法测定了18名健康受试者的运动代谢率。每位受试者在1年的时间里每月接受一次测试。有四个变量呈现出年节律,其高峰期出现在以下几个月:10月的呼吸商;4月的运动代谢率;2月运动时的心率加速度;8月的体脂百分比。
