Table 3 Multiplicative allometric modeling of the absolute VO2peak combining body size descriptors with chronological age (n = 51)
From: Allometric scaling of aerobic fitness outputs in school-aged pubertal girls
ln (VO2peak) = k × ln (Xi: size descriptor) + a + b × (Z: chronological age) + ln (ε) | Model Summary | ||||||
