Abstract

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 be for and after the exercises.
Analysing of the data showed:
1. There was a significant difference in HCf, MCHC and MCV response
of athletes and non-athletes to maximal exercise, while no significant differences were observed regarding HOB, MPV, PL T, 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
