解析:496. b-Decreasing muscle tissue resulting from disuse atrophy will decrease Resting Metabolic Rate (RMR)and increasing muscle tissue will increase RMR. Decreasing mu tissue requires less energy in daily metabolic function and the calories previously used by muscle tissue will be stored as fat废用性萎缩引起的肌肉组织减少会降低静息代谢率(RMR),增加肌肉组织会增加RMR。减少肌肉组织在日常代谢功能中所需的能量较少,肌肉组织先前使用的热量将作为脂肪储存起来
