A Reference Equation for Normal Standards for VO 2 Max: Analysis from the Fitness Registry and the Importance of Exercise National Database (FRIEND Registry)

Existing normal standards for maximal oxygen uptake (VO2 max) are problematic because they tend to be population specific, lack normal distribution and portability, and are poorly represented by women. The objective of the current study was to apply the Fitness Registry and the Importance of Exercise: A National Data Base (FRIEND) Registry to improve upon previous regression formulas for normal standards for VO2 max using treadmill testing....
