| Outline of Final Research Achievements |
The present study aimed to investigate the blood glucose and blood lactate kinetics between the endurance runner group and the control subject group during the incremental running test and examined the hormonal responses effect on blood glucose and blood lactate kinetics in different training states. In this study, the correlation between catecholamine (adrenaline, noradrenaline) responses and the blood glucose kinetics during the incremental running test was higher in the endurance runner group than the control subject group, thus blood glucose increased with high catecholamine stimulation was observed in only endurance runner group. In contrast, blood lactate kinetics was highly correlated with catecholamine responses in both groups. Therefore, during incremental exercise, blood glucose and blood lactate kinetics were maintained by different mechanisms, and blood glucose kinetics may reflect a different physiological parameter than blood lactate kinetics.
