Abstract
Background and Objectives
Physical activities can make different hematological changes. The aim of this research was to evaluate the response of hematological indices and the changes of iron and ferritin subsequent to 6 months of aerobic exercise.
 
Materials and Methods
In this semi-experimental study, 19 sedentary middle-aged women with the mean age of 42.2 ± 3.3 years and the mean weight of 64.0 ± 8.6 kg, were randomly divided into two groups: experimental and control. Experimental group underwent aerobic exercise for six months.
 
Results
Plt (p = 0.045) showed a significant increase (267636.3 ± 65966.3) and iron (p = 0.008) and Ferritin (p = 0.017) showed a significant decrease in the experimental group. The changes between groups in Plt (p = 0.033), iron (p = 0.015) and Ferritin (p = 0.026) were significant.
 
Conclusions 
Increase in the number of platelets may indicate an increase in platelet aggregation and activation. Persons apt/suffering from cardiovascular diseases should perform exercises with low to moderate intensity in order to minimize the risk.
