Table 1.

Characteristics of three groups of elderly subjects that ingested either 15 g of whey protein, 6.72 g of essential amino acids (EAA), or 7.57 g of non-essential amino acids (NEAA).

Whey Protein
(3M, 2F)		 EAA
(4M, 1F)		 NEAA
(2M, 3F)
Age (years) 65.4 ± 2.3 67.8 ± 3.1 64.0 ± 1.6
Weight (kg) 79.5 ± 2.7 79.3 ± 5.8 72.4 ± 6.5
Height (cm) 166.2 ± 3.2 174.2 ± 3.7 164.0 ± 4.6
Body fat (%) 33.0 ± 4.7 29.0 ± 2.3 32.7 ± 4.2
Body lean mass (kg) 50.8 ± 2.8 54.0 ± 4.1 47.4 ± 6.2
Leg lean mass (kg) 8.0 ± 0.5 8.3 ± 0.7 7.3 ± 1.0

Values are presented as means ± SEM. n=5 for each group. M, male; F, female. The EAA and NEAA mixtures were prepared to contain the EAA and NEAA, respectively, found in 15 g of the whey protein. There are no significant differences between groups by ANOVA (P > .05).
