Blood Cell Response to Exercise

January 18, 2022 updated by: USDA Grand Forks Human Nutrition Research Center
Moderate exercise is recommended to improve cardiovascular health in obese and overweight people particularly with metabolic syndrome (MetS) that have hypertension, elevated fasting blood sugar, and elevated blood lipids. This study is being done to determine how platelets respond when a person performs an initial period of moderate exercise.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Platelet Reactivity
Time Frame: Baseline, post-intervention (24 hours), & time points during the exercise phase: prior to exercise (-25 min, -10 min, - 1 min), 10 minutes into the routine, at completion (25 minutes), and 20 & 60 minutes following completion
We hypothesize that moderate physical exercise will increase platelet reactivity in sedentary individuals with metabolic syndrome. Platelet reactivity will be measured by flow cytometry using anti-CD61 antibodies as a marker for platelets and anti-CD62 (P-selectin) as a marker of platelet activation. This will be measured at baseline, post-intervention and time points post-baseline in each subject.
Baseline, post-intervention (24 hours), & time points during the exercise phase: prior to exercise (-25 min, -10 min, - 1 min), 10 minutes into the routine, at completion (25 minutes), and 20 & 60 minutes following completion
