Muscle Function and Energetics

摘要: Lack of nutrient intake results in a loss body fat and lean tissue [1] hitherto the effects nutritional depletion repletion with refeeding have been judged by changes composition, especially tissue. Lean is composed water, minerals, nitrogen glycogen [2, 3], feeding wasted individuals gain multiple elements [4] as well fat. One responding to potassium, which has used an index cell mass [5], metabolically active component We [6, 7] others [8–10] shown that contrast nitrogen, potassium responds rapidly both oral [7] intravenous routes 8–10]. These interpreted being due mass. However, early restitution without rise indicates ion uptake occurs earlier than protein synthesis support [9]. In this conclusion it shown, using selective electrodes, hypocaloric fall muscle membrane potential concentration intracellular ionic K+ [11, 12]. The were specifically related deprivation they could not be reversed supplementation per se [12].
