Abstract
Background and Study Aim. Training activities and altitude cause some of changes in the physiological adaptations and also athletic functionality. The purpose of this study was the effect of altitude and progressive exercise activity on the profile of testosterone changes and Some of immunity markers in active student basketball team.
 Material and Methods. As to subjects this survey, 36 active male students with an average age of (19.5± 0.83) were selected from 36 athletes with a maximum rate of oxygen uptake of about (VO2max=58.66± 2.9). The subjects, who were tested in the sea level f and post IAE (8 of periodical ascending to the height of 2800 meters for 3 days), were then asked on cycle ergometer (starting with 100 watts, increasing 25 watts every 3 minutes, with the work-to-rest ratio of 3 to 1) to exhaustion. The initial blood sampling of the subjects was done 72 hours before the main test to determine the similar conditions of the subjects, and to measure the initial level of Testosterone hormone, lymphocytes and neutrophiles, in the sea level. Also, the blood sampling of both after and before the progressive exercise activity and the IAE stage were done. The serumal concentration of testosterone was measured via Elisa method and the amounts of lymphocytes and neutrophiles were determined using Cell-Counter set. For statistical analysis, using the tests of Kolmogorov and Smirnov, repeated measurements were done in the level of (p≤0.05). The complete process of analyzing the result was done through the software SPSS22.
 Results. The outcomes of the present survey show the amount of lymphocytes and neutrophiles after a session of progressive exercise activity have had a meaningful increase (p<0.05). But, the increase rate of testosterone was not meaningful difference (p>0.05). Testosterone, lymphocytes and neutrophiles showed a meaningful increase after progressive exercise activity in IAE conditions (p<0.05). Also, the amounts of Testosterone, lymphocytes and neutrophiles, before IAE has not shown a meaningful rise, when compared to sea level conditions (p>0.05). 
 Conclusions. It seems that, even though these changes were not meaningful, they were effective in reducing both the functionality of the subjects and the exhaustion duration. Therefore, it seems that repeated IAE sessions over three days can provide physiological adaptations to height and decrease Prevent performance.
Highlights
Material: As to subjects this survey, 36 active male students with an average age of (19.5± 0.83) were selected from 36 athletes with a maximum rate of oxygen uptake of about (VO2max=58.66± 2.9)
The results indicate that salivary testosterone concentration in native men is significantly higher than non-native men [27]
The present study investigates the effect of periodic hypoxia and the increasing activity of testosterone profile and some safety indices of active student basketball team
