Abstract

 
It has been suggested that regular aerobic training is resulted to hematological changes. However, there is not a general agreement about the effect of a single session of weight circuit exercise. The purpose of this study was to investigate weight circuit exercise on hematological responses.
Fourteen physical education students (age 20.57 ± 0.51 years, 78.25 ± 5.01 in weight, 175± 2.2 cm in height, and 25.27± 1.18 kg/m2) volunteered to participate in the present study. Subjects were asked to perform nonstop weight circuit exercises (10exercise at 60% 1RM, 20s time for each, 3 circuits with 3min rest between circuits). Blood samples were taken at pre and immediately after exercise while the subjects were overnight fast (at least 12h). White blood cells (WBC) and its related variables red blood cells and its related variables, platelets (PLT), RDW, MPV, P-LCR, and PDW were measured. Data were analyzed by using paired sample student T-test. Data were given as a Mean ± SE. The differences were accepted at alpha £0.05. 
Significant changes were found in WBC counts, MCV, PLT, RDW, MPV, and P-LCR. RDW significantly decreased. Insignificant changes were observed in other mentioned variables.
The present findings indicate that single weight circuit exercise can be accounted as a stimulus for hematological responses. Further research need to clarify mechanisms which are involved such changes.
