A Comparison Between Ventilation and Heart Rate as Indicator of Oxygen Uptake During Different Intensities of Exercise
Physical activities light to moderate intensities steady state activities non-steady state activities
2015/5/4
The aim of this study is to compare the relation between ventilation (VE) and oxygen uptake (VO2) [VO2=ƒ(VE)] and between heart rate (HR) and VO2 [VO2=ƒ(HR)]. Each one of the subjects perfor...
