Do the speeds defined by the American College of Sports Medicine metabolic equation for running produce target energy expenditures during isocaloric exercise bouts?
The accuracy of the American College of Sports Medicine (ACSM) equations for producing predicted values of heart rate reserve (HRR) and oxygen uptake reserve and consequently, target energy expenditure (EE) during exercise are yet to be established. This study investigated whether speeds defined by...

Zusammenfassung: | The accuracy of the American College of Sports Medicine (ACSM) equations for producing predicted values of heart rate reserve (HRR) and oxygen uptake reserve
and consequently, target energy expenditure (EE) during exercise are yet to be established. This study investigated whether speeds defined by the ACSM metabolic equation for running correctly estimate the EEs during isocaloric exercise bouts. Twenty-eight men performed a ramp-incremental maximal exercise test to determine HR
max
and
Two continuous exercise bouts at 60 and 80%
and target EE of 400 kcal were then performed. In the 60%
exercise the observed
and EE were lower than predicted only during the first time quartile of the bout (
