Comparison the effect of Maximal and Sub-Maximal Exercises on Hematological Parameters in Athletic & Non-Athletic Young male Students

The main purpose of this study was to compare the effect of maximal and sub-maximal exercises on hematological parameters in athletic and non-athletic young male students. 90 students (46 athletes, 44 non-athletes) with an age range of 15 to 17 years were selected randomly in Tehran. They practiced both maximal and sub-maximal exercises under the Bruce test for one week. In sub-maximal exercise they were allowed to continue the bruce test and to stop the exercise whenever their heart rate reached to 150. In maximal exercise they were instructed to exercise until exhaustion. Blood samples were taken befor and after the exercises. Analysing of the data showed: 1. There was a significant difference in HCT, MCHC and MCV response of athletes and non-athletes to maximal exercise, while no significant differences were observed regarding HGB, MPV, PLT, RBC, RDW and WBC variables in two groups. 2. No significant difference was witnessed regarding hematological parameters between two groups caused by sub-maximal exercise.
