Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change 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.	Baseline and every minute post exercise for a maximum 20 minutes post exercise.
