were similar among the 4 beverage treatments. Plasma free fatty acid concentration was significantly higher in NF and W than in CHO and CHO-ION.
VO2 was significantly lower in CHO-ION than in the other treatments at 60 min of exercise, and from 90 min of exercise, VO2 was significantly lower in CHO and CHO-ION when compared in NF and W. No differences existed in VO2 between NF and W, but slightly higher in W.
HR was significantly higher in NF from 15 min of exercise than the oher treatments but no differences existed in HR among the beverage treatments with fluid replacement.
Second, plasma insulin concentration, plasma glucose concentration and respiratory exchange ratio(RER) were decreased during exercise in NF and W. Plasma insulin concentration was significantly decreased during the exercise in NF and W, but insignificantly decreased in CHO and CHO-ION. And no differences existed in plasma insulin concentration among the 4 beverage treatments.
Plasma glucose concentration was significantly decreased during exercise in NF and W but maintained resting level in CHO and CHO-ION.
RER was significantly higher in CHO-ION than in the other treatments from 30 min of exercise. From 90 min of exercise, the difference between CHO and CHO-ION was not significant. RER was significantly higher in CHO than in NF and W from 30 min of exercise. RER between NF and W was significant difference at 120 min of exercise and was lower in W.
Third, Hemoglobin, hematocrit and blood osmolality were significantly increased during exercise only in NF. But in the 3 beverage treatments with fluid replacement, hemoglobin, hematocrit and blood osmolality maintained resting levels.
Fourth, blood volume and plasma volume were decreased during exercise but in fluid replacement 3 beverage treatments, blood volume and plasma volume showed a tendency to recovery after decrease in the early exercise. In NF, blood volume and plasma volume at 60 min of exercise were decreased 7.4±1.6% and 12.3±1.4% than resting levels, respectively. And then blood volume and plasma volume at 120 min of exercise were decreased 10.1±2.3% and 17.3±3.8%, respectively. Blood volume and plasma volume were significantly lower in NF than the other treatments, but no differences existed in blood volume and plasma volume among the 3 beverage treatments with fluid replacement.
Fifth, total sweat volume was similar among the 4 beverage treatments.
From the results, this study showed that beverage ingestion influenced energy metabolism during prolonged exercise in the heat and carbohydrate-electrolyte beverage maintained more effective carbohydrate oxidation within cell than water and carbohydrate beverage, and that carbohydrate-electrolyte beverage was similar to water and carbohydrate beverage in minimizing exercise-induced disturbances in blood volume and cardiovascular function during prolonged exercise in the heat.
Keywords : the heat, carbohydrate-electrolyte beverage, energy metabolism, blood volume,
