| Outline of Final Research Achievements |
We examined any merits of the supplementation of a mixture of carbohydrate and protein during exercise training. First, we divided older men into 2 groups; carbohydrate + protein (Pro-CHO) and carbohydrate (CHO) supplementation groups. After 2-mo training, we found that thermoregulatory responses more improved with more increases in plasma volume and albumin content in Pro-CHO than CHO but arterial blood pressure decreased in both groups. Second, we divided older women into 3 groups; control (CNT), low (L-Pro-CHO), and high carbohydrate + protein (H-Pro-CHO) supplementation during interval walking training. After 5-mo training, we found that muscle strength, plasma volume, and inflammatory genes methylation increased more in H-Pro-CHO than CNT. In addition, the inter-individual variation of renal Na+ reabsorption rate in response to plasma insulin concentration during OGTT was smaller in H-Pro-CHO than in CNT. Thus, the supplementation might enhance the benefits of exercise training.
