Reduction in Lower Body Strength
The graph on this slide illustrates the reduction in lower body strength after 28 days of bed rest. As on the previous slide, the green bar represents the group that received the amino acid suupplement only. The group represented by the yellow bar received the amino acid supplement plus resistance training; and group represented by the orange bar had a combination of the amino acid supplement, resistance training and timing. Lower body strength was reduced by 24% in the amino acid only group. Resistance training mitigated the reduction of strength, and timing further enhanced the protective effect. An important difference between this bed rest study (Tufts) and the Wolfe bed rest study was that all subjects in the Tufts study received only 85% of their daily energy requirement. The effectiveness of the amino acid supplement alone was much less in this study than was observed in the Wolfe study.
