Summary
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 occured 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.
