Results
From [Table/Fig-3], it becomes clear that equation (c) had the highest aR2 (adjusted R2) of 76% with both its IVs having significant β-weights. Out of BF, BMI & Hb, only BMI contributed a statistically significant unique variance of 3.66% out of the total variance in VO2max/LBM, over & beyond that explained by gender. This was followed by Hb (2.6%) & BF (1.4%), though statistically insignificant [Table/Fig-3b,c,d].
