Compendium of physical activities: an update of activity codes and MET intensities.

abstract：PURPOSE:Aerobic training of professional road cyclists is linked to tremendous aerobic capacities that have never been clearly related to what occur in skeletal muscles submitted to a specific exercise. The aim of the present study was to examine specifically metabolic recovery after an incremental cycling exercise per...
