High temperature environment causes detrimental effects on health. In the present study, the effects of intake of several kinds of beverage on blood components during exercise under the high temperature environ-ment were evaluated. The 10 subjects were student of the H University. Exercise intensity was 50-60% O2maxx and treadmill exercise was contin-ued for 1 h. The kinds of beverage were water, ion beverage, cucumber drink. Blood sampling was performed before the exercise, immediately finishing exercise, and 30 min after rest. In the present results, glucose concentration was increased by intake of water, ion beverage, and cu-cumber drink immediately after exercise. In the water intake group, glu-cose concentration was decrease 30 min after rest. Free fatty acid con-centration was increased by intake of water, ion beverage, and cucum-ber drink 60 min after exercise. In the ion beverage and cucumber drink intake groups, free fatty acid concentration was decreased 30 min after rest. Insulin concentration was increased by intake of water, ion bever-age, and cucumber drink 60 min after exercise. In the water intake group, insulin concentration was decrease 30 min after rest. There was no dif-ference in the efficacy among water, ion beverage, and cucumber drink, but ion beverage and cucumber drink showed more potent effect on metabolic parameters.
