Abstract

This study is to verify the effect of the assumed environmental altitude (FiO =
15.72% at 2500m altitude) continuously to change some physiological,
biochemical and body components of flowing water. male withdrawal in this
study. Twenty males were randomly divided into two groups, the hypoxic
group (H) 2500m (n = 10, age: 20 ± 1.789 years, body height: 173.13 ± 4.75
cm, body weight: 62.7 ± 4.545 kg) and control (C) group (n = 10, age: 21 ±
2.881 years old, body height 179.03 ± 3.69 cm, body weight: 67.70 ± 4.4 kg).
For 8 weeks, all subjects conducted three intense interval training sessions per
week. During the alternative training sessions, the group (H) was trained in a
normal oxygen-reduction chamber at a simulated height of 2500m, while
group (C) conducted alternating training under Normoxia conditions also in
the chamber. Each session consists of four to five times 5 minutes with 90% of
the VO2max velocity determined in hypoxia (VO2max-hyp) for the group
(H) and 90% of the velocity at VO2max determined in Normoxia for the
group. (C). (The speed is increased linearly by 1 km / h every 1 minute until
the exhaustion of will during run time ?5 minutes). After the training
program, the results showed that both groups had significant changes (p
<0.05), but the analysis showed that the group (H) in training on hypoxia
caused significant changes. . (p <0.05), better than the group (C) (HRmin
reduced -9.17bpm, live capacity (VC) to 0.42 liters, increased 3000m running
(0.94%), VO2max (3.98% ), hemoglobin (1.3%), hematocrit (3: 47%), EPO
decrease (-2.07%)
Keywords: Heart rate (HRmin); VO2max; red blood cell (RBC); hemoglobin
(Hb); male sprinters.
