Influence of Cardiorespiratory Fitness and Body Composition on Resting and Post-exercise Indices of Vascular Health in Young Adults

Influence of Cardiorespiratory Fitness and Body Composition on Resting and Post-exercise Indices of Vascular Health in Young Adults

This research is being done to determine whether acute exercise causes differences in numbers of novel blood factors associated with vascular health in college-aged adults across different physical activity habits. As only ~50% of cardiovascular (CV) events can be explained by traditional CV risk factors such as high blood pressure and high cholesterol, it is anticipated that this research will provide a more comprehensive look into novel risk factors that may better explain CV risk and that may be modifiable through regular physical activity.

Inclusion Criteria:

• 18-29 years of age; healthy male and female; Physically inactive, defined as participation in less than 20 min of continuous endurance exercise on fewer than 2 days/week; Recreationally active, defined as participation in 30 min/day of moderate-intensity cardiovascular activity on greater than 4 days/week; Highly active- defined as performing 30-60 min of moderate- to vigorous-intensity endurance exercise greater than 5 days/week.

Exclusion Criteria:

• currently pregnant, previously diagnosed coronary heart disease or congenital heart disease, serum total cholesterol >200 mg/dl, low-density lipoprotein cholesterol >130 mg/dl, high-density lipoprotein cholesterol < 35 mg/dl, fasting glucose >100 mg/dl, systolic blood pressure > 130 mmHg, diastolic blood pressure >90 mmHg, and BMI >30 kg/m2.
