Summary

This study looks at how being overweight or obese changes blood pressure during different breathing tasks and exercise. Researchers at Florida State University will measure blood pressure in 80 healthy adults at rest and during aerobic and breathing muscle tests. The goal is to better understand the link between obesity and heart health.
