The Hemostatic Effects Of Acute Exposure To Colored Cornstarch Powder During A 5k Run, Robert C. Allsbrook
Senior Honors Projects, 2010-2019
PURPOSE: To examine the acute hemostatic effects of particulate matter (PM) in the form of colored corn starch powder during a 5 kilometer race. METHODS: 10 recreationally active adults completed two 5k runs, one with color and one without color. 10 mL blood samples were taken 6 hours prior to the trial and immediately following the trial. PAI-1 activity, FVIII antigen, and tPA activity were measured using an ELISA. RESULTS: No significant main effects or interaction effects (P<0.05) were observed among any of the variables although a trend (P = 0.082) was observed for increased PAI-1 activity during exercise in the color condition. CONCLUSIONS: There is a trend towards increased PAI-1 activity levels during exercise during color runs that could be due to increased inflammation. Furthermore, the lack of increased FVIII:ag and tPA activity suggests that the intensity of the exercise may not have been adequate and further research should be conducted in this area.
