Outline of Final Research Achievements |
Protein intake, particularly branched chain amino acids (BCAAs), and exercise have opposing actions on insulin secretion, but the same action on protein anabolism. We examined the effects of BCAA-rich fat-free milk intake and/or exercise on levels of insulin secretion and indices related to muscle protein metabolism in order to assess the potency of dietary and exercise therapies against metabolic and locomotive disorders. Adult male or female volunteers participated in the metabolic studies. Urinary C-peptide immunoreactivity excretion and serum insulin levels were significantly higher, but urinary 3-methyl-histidine excretion levels were significantly lower with low urinary catecholamine excretion in the fat-free milk-containing diet than in the control diet. These findings were reduced by exercise with high urinary catecholamine excretion. Fat-free milk intake enhanced insulin secretion and suppressed muscle protein degradation, but these effects are attenuated by exercise.
