Physiological Function and Body Composition Reaction After 8 Weeks of Training at 2500m Hypoxia Chamber of Male Sprint

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 thisstudy. Twenty males were randomly divided into two groups, the hypoxicgroup (H) 2500m (n = 10, age: 20 ± 1.789 years, body height: 173.13 ± 4.75cm, 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 perweek. During the alternative training sessions, the group (H) was trained in anormal oxygen-reduction chamber at a simulated height of 2500m, whilegroup (C) conducted alternating training under Normoxia conditions also inthe chamber. Each session consists of four to five times 5 minutes with 90% ofthe VO2max velocity determined in hypoxia (VO2max-hyp) for the group(H) and 90% of the velocity at VO2max determined in Normoxia for thegroup. (C). (The speed is increased linearly by 1 km / h every 1 minute untilthe exhaustion of will during run time ?5 minutes). After the trainingprogram, the results showed that both groups had significant changes (p<0.05), but the analysis showed that the group (H) in training on hypoxiacaused significant changes. . (p <0.05), better than the group (C) (HRminreduced -9.17bpm, live capacity (VC) to 0.42 liters, increased 3000m running(0.94%), VO2max (3.98% ), hemoglobin (1.3%), hematocrit (3: 47%), EPOdecrease (-2.07%)Keywords: Heart rate (HRmin); VO2max; red blood cell (RBC); hemoglobin(Hb); male sprinters.
