Fig. 2. Prevalence of 8-yr change in fat-free mass (FFM) (top) and body fat (BF) (bottom) in sedentary (S) and active (A) men and women aged <45 yr and 
45 yr. Black bars, loss >3%; gray bars, stable; open bars gain >3%. n = number of subjects. Differences (
2) between sedentary and active were significant for FFM in women <45 yr, 2 8.8, degrees of freedom, 2; p = 0.01; women 45 yr, 2 7.9, degrees of freedom, 2; p = 0.01. Differences for BF in sedentary versus active were non-significant.
