Effects of hypervolemia by protein and glucose supplementation during aerobic training on thermal and arterial pressure regulations in hypertensive older men

The incidence of heat illness has rapidly increased in older people during the midsummer. Protein+carbohydrate supplementation during aerobic training reportedly increased plasma volume to enhance thermoregulatory adaptation; however, in hypertensive older people, the symptoms may be worsened by hypervolemia. We demonstrated that in hypertensive older men, protein+glucose supplementation during aerobic training increased plasma volume and thermoregulation, but blood pressure rather decreased. Thus, we find the prescription to be applicable to hypertensive older people to prevent heat illness.
