This study was designed to examine the effect of 4 weeks fixed and mixed intermittent hypoxic training (IHT) on exercise load, oxygen delivering capacity of the blood, energy metabolism, and skeletal muscle oxygenations. Thirty three male college students participated in the study as subjects and divided into three groups such as control group (n=11) performed training at sea-level, fixed IHT group (n=11) performed training at 16.5% O₂, and mixed IHT group (n=11) performed training at 14.5% O₂ (~2 weeks) and 16.5% O₂(~4 weeks). They performed cycle exercise (30 min) and treadmill exercise (30 min) within 80%HRmax developed Miyashita et al. on 1985. Exercise frequency was 1hour, 3days per a week, 4 weeks. At rest and during exercise, exercise load, Hb concentration, Hct, %SPO₂, VO₂, blood lactate level, △O₂Hb, △HHb, and TOI was measured before and after training (Pre and Post) in each groups. As a result, 4weeks fixed and mixed IHT does not induced improvement on oxygen delivering capacity of the blood through Hb concentration and Hct. However, exercise performance increased by fixed and mixed IHT through improvement of oxygen flux to muscle tissue, exercise economy, and lactate tolerance of the blood. Also, these physiological improvement appeared effective in mixed IHT compared with fixed IHT. In later research, various studies need to investigation of the effect to fixed and mixed IHT on oxygen flux, oxygen delivering capacity, lactate tolerance of the blood, exercise performance, and time trial in elite athletes.
