RECRUITINGChange of heart rate after submax exercise
The participants then were fitted to cycling shoes and familiarized with the Lode cycle ergometer (Lode Excalibur Sport, Groningen, Netherlands), completed a warm-up and were asked to perform a criterion work rate trial ending at 80% predicted HRmax. Heart rate was recorded every minute post exercise for a maximum of 20 minutes post exercise.
Time frame: Baseline and every minute post exercise for a maximum 20 minutes post exercise.
