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. Elite Taekwondo athletes (n=25 out of 30) participated in the study as subjects and divided into three groups such as control group (n=8) performed training at sea-level, fixed hypoxic group (n=9) performed training at 16.5%O₂, and mixed hypoxic group (n=8) 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, 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 hypoxic training does not induced improvement on oxygen delivering capacity of the blood through Hb concentration and Hct. However, blood lactate concentration, △O₂Hb, △HHb, and TOI improved in mixed and fixed hypoxic training groups compared with control group. As a results, despite no difference on exercise load between three groups, VO₂ presented a lower increase in mixed and fixed hypoxic groups compared with control group. In other words, we confirmed that the increase of exercise economy in mixed and fixed hypoxic groups compared with control group. Also, the increase of exercise economy appeared most notably in mixed hypoxic training group.
