Platelets are small, anucleated blood elements and under normal conditions constitute a small fraction of the circulating cells. A growing body of recent research reports indicates that platelet functions in the human body are influence by physical training and regular exercise habit.
Objective: The objective of the present study was to investigate the effect of twelve minutes run and walk on platelet variables.
Method: Present Study was conducted in the Visva Bharati University campus, west Bengal, India. To meet the purpose of this pilot study two male healthy physical education students, aged between 20-22 years, non-smoker were acted as subject of the study. Platelet Aggregation profile i.e., collagen aggregation, epinephrine aggregation, ADP aggregation and arachidonate aggregation, Bleeding time and clotting time was measured before and immediately after the completion of twelve minute run and walk test. In this study mean and SD was calculated to observe the changes after exercise.
Results: Mean value of collagen aggregation (pretest 79.5 ± 0.70% to posttest 81.5 ± 0.70%), epinephrine aggregation (pretest 71.5 ± 0.70% to posttest 73.0 ± 0%); ADP aggregation (pretest 77 ± 2.82% to posttest 77.5 ± 4.94%) Ristocetin aggregation (pretest 89.5 ± 0.70% to posttest 91.5 ± 0.70%), bleeding time (pretest 155 ± 35.35sec to posttest 165 ± 35.35sec) and clotting time (240 ± 7.07se to posttest 254 ± 8.48sec) were increase from the pre exercise value to completion of exercise, where as Arachidonate aggregation was decreased from 83.0 ± 0% to 82.5 ± 3.53% respectively.
Conclusion: Platelet aggregation induced by Collagen, Epniephrine, Ristocetin and ADP was increase may be due to release of fresh platelet from the spleen, bone marrow, or other reservoirs in the body. Bleeding and clotting time shows that, after doing exercise it was gradually increase due to elevation of neither the circulating nor epinephrine during exercises.
