Habitual Physical Activity Levels in Older Obese Individuals Are Associated with Improvements in Health-Related Physiological Parameters
Hypothesis
Greater levels of reported physical activity will be associated with higher levels of aerobic fitness and improved markers of health.
Methodology
A cross-sectional retrospective study of overweight and obese men (n = 23) and women (n = 33) was conducted. Subjects completed the Minnesota Leisure Time Physical Activity Questionnaire to quantify leisure time physical activity levels over the previous 12 months. Physiological measurements including VO2 Max Test, Dual Energy X-Ray Absorbtiometry, Oral Glucose Tolerance Test and Hyperinsulinemic Euglycemic Clamp were collected on each subject and analyzed.
Outcomes
The study supports the hypothesis that overweight and obese individuals can benefit from increased physical activity levels. This study shows that higher levels of physical activity may result in improvements in insulin sensitivity, body fat and aerobic capacity.
