This study was designed to examine the effect of 2weeks living low training high (LLTH) under 2,000 m and 3,000 m simulated hypoxic environments on exercise load, oxygen delivering capacity of the blood, energy metabolism, and skeletal muscle oxygenations. Twenty eight male college students participated in the study as subjects and divided into three groups such as control group (n=8), 2,000 m LLTH group (n=10) and 3,000 m LLTH group (n=10). They performed cycle exercise (30 min) and treadmill exercise (30 min) within 80%HRmax developed Miyashita on 1985. Exercise frequency was 1hour, 3days a week, 2weeks. At rest and during exercise, exercise load, Hb concentration, Hct, %SPO₂, VO₂, blood lactate level, △O₂Hb, △HHb, and TOI were measured before and after training (Pre and Post). As a result, 2weeks LLTH under 2,000 m and 3,000 m simulated hypoxic environments does not induced improvement on oxygen delivering capacity of the blood through Hb concentration and Hct. However, energy metabolism and skeletal muscle oxygenation have been improved by LLTH. These changes improve oxygen supply to muscle tissue, oxidative phosphorylation process in mitochondria, lactate tolerance of the blood, and exercise performance. Also, these physiological changes presented a similar pattern in the 2,000 m and 3,000 m LLTH groups. In later research, various studies need to the effect of LLTH under simulated hypoxic environments on various physiological variables and exercise performance.
