In a single-blind, matched group design: branched-chain amino acid supplementation and resistance training maintains lean body mass during a caloric restricted diet

Table 2 Changes in body mass variables before and after 8 week study period

	Age (yrs)	Height (cm)	Body Mass (kg)	Lean Mass (kg)	Fat Mass (kg)
BCAA	24.7 ± 0.6	177.9 ± 4.6	84.3 ± 5.2	72.2 ± 4.7	12.2 ± 0.7
BCAA	24.7 ± 0.6	177.9 ± 4.6	84.2 ± 4.8	72.6 ± 4.3	11.6 ± 0.7^a
CHO	23.5 ± 0.6	176.6 ± 5.6	78.3 ± 2.9	67.8 ± 2.5	10.5 ± 0.5
CHO	23.5 ± 0.6	176.6 ± 5.6	76.0 ± 2.4^a	66.9 ± 2.5^a	9.1 ± 0.7

^adenotes significant difference (p < 0.05) within BCAA and CHO
All subjects were prescribed the same hypocaloric diet and exercise programs. The BCAA group received 28 g of BCAA (14 g prior/during each workout and 14 g post workout) while the CHO group received 28 g of a carbohydrate/electrolyte supplement (14 g prior/during each workout and 14 g post workout)
