Quantify the Effect of Repeat Periodic Running Exercise Teenagers - A Case Study in Hong Kong

In this study, we intend to explore the relationship between running training as a form of exercise and pulmonary functions by conducting a case-control study. A total of 329 subjects coming from five schools were sampled, 149 boys and 180 girls, with age between 14 and 21. Subjects were then assigned to two groups (experimental and controls) using a system of random number tables. Pulmonary function tests and their BMI were measured for all the subjects before exercise with the help of a digital spirometer. The experimental group is required to perform repeat periodic running exercise for 20 minutes, three days per week, for eight consecutive weeks. The running exercise was supervised by trained staff. The control group continued with the routine and performs no specific exercise. Pulmonary function tests were repeated after eight weeks for both experimental and controls groups.
