Effects of a Low Intensity Circuit Resistance Exercise Session on Some Hematological Parameters of Male Collage Students

This study aims to survey the effects of a circuit resistance training session with a light intensity on some hematological parameters of male students of Physical Education. After the release of an announcement and call, 20 male students of Physical Education voluntarily participated in this study. After equalization, they were randomly divided into two groups including light-intensity exercise (35% of a maximum repetition) and no exercise (the control). Persons in the first group were asked to perform 10-step circuit exercise for three non-stop alternating rounds with a rest period at each round. Hematological parameters measured included white blood cells, platelet variables, and red blood cells. Data was analyzed using SPSS software. To compare the means before and after the exercise and to compare to groups with each other, dependent t-test and independent t-test were used, respectively. Results showed that none of the variables related to white blood cells and platelet had a significant change in the group of light-intensity exercise (35% of a maximum repetition) and only mean corpuscular volume (MCV), among the variables related to red blood cells, decreased significantly. In the control group, a significant increase in neutrophil percent (NEUT) and hemoglobin and a significant decrease in lymphocyte percent (LYM) were observed. Other variables showed no significant change in this group. In addition, there was no difference between the groups.
