The Matthews (1999) equation for predicting VO2max without using exercise established that it could predict 74% of the variance in VO2max with the following variables: physical activity levels, height, age, body mass, and sex with the equation below.
VO2 max = (0.113•age) - (0.005 • age^2) + (11.053 • sex) + (1.463• PA - R)+ (9.17 • height) - (0.254 • body mass) + 34.142
Where sex = 1 for males and 0 for females. PA - R = physical activity rating and height is in meters
What was the R^2 value for this equation.
-0.55
-0.74
-0.86
-0.05
