Abstract:
5 male adults were studied in continuous bed rest for 16 days. The total body fat was measured by modified water displacement method (density method). The loss of body protein was measured by calculating nitrogen balance. The results have shown that during the experimental peroid their body protein decreased by 167 to 376 g and the body fat increased by 1.28?0.38kg. The average caloric requirement was 1958 ? 242 kcal/man/day, 32.3?1.6 kcal/kgBW/day or 36.1?1.4 kcal/kg LBW/day. These results are similar to those provided by other methods such as dietary survey or gas metabolism.
