Promoting alternative physical load measurement method : approacing %VO2 max through HR

The unit of kcal/min as physical load indicator unit has been broadly used. However, comparing physical load among different individuals by applying this unit may result in bias conclusion. Avoiding this bias, the use of %VO2max (percentage of oxygen uptake maximum) as physical load indicator unit w...
