Outline of Final Research Achievements

The present study aimed to clarify time course of improvements in cardiovascular and metabolic risk makers to exercise training with various conditions under hypoxic conditions and detraining. The results indicated that exercise training under hypoxic conditions induce more effectively improvements in cardiovascular and metabolic risk factors compared to the exercise under normal conditions, and that the improved risk factors are maintained for 8 weeks following cessation of the training. Also, the improvements after the training did not differ in the range of intensities from 50% to 60% of VO2max, and obtained within shorter period under hypoxic conditions corresponding to 2500m above sea level when compared to the exercise under 2000m above sea level. Furthermore, the repetitive short-term (i.e. 4 days) hypoxic training with 2 weeks of detraining could improve cardiovascular and metabolic risk factors.
