This study has measured the pulmonary function by treadmill test for 6 young women who were in twenties, and analyzed the respiratory-circulatory function and the change of hormone and immune response after performing the exercise program (60% severity) for 10 weeks.
The results are as follows;
1. 10 weeks regular exercise made a decrease in weight and body fat proportion, and improved the respiratory-circular function by increasing the maximum oxygen absorption and ventilation.
2. 10 weeks regular exercise made a significant increase in count of WBC, lymphocyte, and T lymphocyte, but a significant decrease in B lymphocyte. NK cell also showed an increase in counts, but insignificant.
3. 10 weeks regular exercise made a significant increase in blood norepinephrine level. Epinephrine and cortisol also showed an increase in count, but insignificant.
In summary, it suggested that 10 weeks regular exercise improves the immune function by decrease in body fat, increase in respiratory-circular function and metabolic efficiency, and also by raising Th/Ts ratio (an increase in count of WBC, lymphocyte, and T lymphocyte, but a decrease in suppressor T lymphocyte).
