This study was to verify the influence of environment assumed elevation (FiO = 15.72% with the altitude 2500m) intermittently to change certain physiological functions, biochemical and body composition of male sprinters in this study. Twelve males were randomly divided into 2 groups, a hypoxia (H) group 2500m (n = 6, age: 20 ± 1.789 years, body height: 171.833 ± 5.672 cm, body mass: 62.7 ± 4.545 kg) and a control (C) group (n = 6, age: 21 ± 2.881 years, body height 178.0 ± 3.688 cm, body mass: 68.017 ± 4.5 kg). After the training program the results showed that both groups had significant changes (p <0.05), but the analysis showed that group (H) in the training in hypoxia caused changes significant (p <0.05), better than group (C) (HRmin reduce -9.17bpm, vital capacity (VC) to 0.42 liters, increase in 3000m run (0.94%), VO2max (3.98%), hemoglobin (1.3%), hematocrit (3:47 %), EPO decreased -2.07%)
