Effects of Endurance Exercise Under High Ambient Temperature on Plasma Prekallikrein and Dopamine-β-hydroxylase (DBH) Activity
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.2 Vol.2】
The present study was to investigate to the question of whether or not endurance exercise under high ambient temperature became the stress to circulatory system. The two subjects who were healthy male exercise on a bicycle ergometer with 70% VO₂max for 15 min under 16℃ and 30℃ environment. The results obtained are as follow:
1) Cardiac output and the systolic blood pressure were higher at 30℃ than at 16℃. Difference in the diastolic values wasn't under each condition.
2) DBH activity levels were slightly higher at 30℃ than at 16℃. There was no difference in plasma prekallikrein levels under each condition.
3) Iresspective of each condition blood lactate concentrations were various with each individual.
