Figure 1.
Body mass index as a function of the physical activity level at baseline (A) and at follow up (B).
Linear regression analysis shows an inverse relationship at baseline (A, continuous line) and no relationship at follow-up (B, discontinuous line), 11±4 yr later, in 40 subjects.
Figure 2.
Change in fat mass as a function of the difference in physical activity level.
Physical activity level at baseline (PAL1) and at follow up (PAL2), 11±4 yr later, in 40 healthy subjects with body-mass indices within the normal range. Linear regression shows an inverse relationship between the change in PAL and the rate of fat mass change.
