초록

The purpose of this study was to investigate the effects of hypobarichypoxic training program on competitive performance. This was done by observing their conditioning and measuring their blood constituents before and after a multi-staged intermittent training program, over 2 weeks. Three national handicapped cyclists were placed in a multi-leveled hypobaric-hypoxic (flat-4000 meter (m) high elevation) environment with consistent temperature and humidity ($23{\pm}2^{\circ}C$, $50{\pm}5%$) for 2 weeks. After the training, the blood constituents and average heart rate (HR) were measured and the following results were obtained. In all three athletes, there were no unique changes in red blood cell count, hemoglobin, and hematocrit, while there was a rise in the reticulocyte count. Observations of the difference in average HR during exercise at varying altitudes showed that athlete A had an average increase in the HR for the first 5 days at 2000 m. For athlete B, the comparison of the first and last training sessions at an altitude of 2000 m showed an HR increase of approximately 17%. For athlete C, there was a steady increase in the HR until day 7 of the training. As such, hypobaric-hypoxic training suggested that improvement of aerobic exercise performance in these athletes and it is recommended that there be a development for future training programs at high altitude, geared towards handicapped athletes of various disciplines.
