Key result
Three months of running exercise reduced RDW and BMI, and elevated WBC, platelet count, and VO2max in untrained overweight middle-aged men.
Why the study?
WBC, platelet count, and RDW are emerging atherosclerosis risk factors, but the effects of three months of running exercise on these variables in untrained overweight middle-aged men were not established.
Does 12 weeks of running exercise alter white blood cell count, platelet count, and red blood cell distribution width in untrained overweight middle-aged men?
Does 12 weeks of running exercise alter white blood cell count, platelet count, and red blood cell distribution width in untrained overweight middle-aged men?
A 12-week running program in untrained overweight middle-aged men significantly alters emerging atherosclerosis risk factors including RDW, WBC, and platelet counts.

Background: White blood cells count (WBC), platelet count (Plt) and red blood cells distribution width (RDW) are some emerging atherosclerosis risk factors. Objectives: The purpose of this research was to study the effects of three months running exercise on these variables in untrained overweight middle-aged men. Methods: Subjects were divided in groups of control (n = 10) and exercise (n = 11). In experimental group, subjects performed twelve weeks (three times per week) running exercise (intensity was between 75% to 85% of maximum heart rate). Blood samples were collected 24 hours before and 48 hours after exercises. Paired t-test was used for analysis of data in SPSS V. 15. Results: Statistical analysis showed significant reduction of RDW and BMI, also significant elevation of WBC, Plt and VO2max after three months exercise in the experimental group (P ⤠0.05); no significant changes was observed in the control group (P > 0.05). Conclusions: In general, three months running exercise may improve blood cells (leucocytes, erythrocytes and platelets) function that may lead to reduction of cardiovascular events risk in middle-aged men, but certainly more research is needed for precise conclusion.

Mohsen Jafari (2019) studied Untrained overweight middle-aged men (n=21). Running exercise vs. Control group was evaluated on White blood cells count (WBC), platelet count (Plt) and red blood cells distribution width (RDW) (p=≤ 0.05). Three months of running exercise reduced RDW and BMI, and elevated WBC, platelet count, and VO2max in untrained overweight middle-aged men.
