The effects of a 16-wk strength-training program on total and regional body composition were assessed by dual-energy X-ray absorptiometry (DEXA), magnetic resonance imaging (MRI), hydrodensitometry in 13 untrained healthy men [60 +/- 4 (SD) yr]. Nine additional (62 6 yr) served as inactive controls. resulted substantial increases both upper (39 8%; P < 0.001) lower (42 14%; strength. Total fat-free mass (FFM) increased 2 kg (62.0 7.1 to 64.0 7.2 kg; 0.001), fat decreased the same amount (23.8 6.7 21.8 6.0 when measured DEXA. When hydrodensitometry, similar FFM (61.3 7.8 63.0 7.6 0.01) decreases 7.9 22.1 7.7 observed.
