Clinical Trials

Are you an adult who gets little exercise and sits a lot every day? If you sit for more than 8 hours a day and exercise less than 90 minutes per week, this study may interest you. Researchers want to see if walking or standing breaks during long sitting periods can make your heart healthier. To take part in this study, you must be 36 to 55 years old. You also should be able to walk four blocks and go up two flights of stairs. The study is taking place in Chapel Hill, North Carolina.

Are you an adult interested in comparing effects of different exercise training on blood pressure?

To participate in this study, you must be between 18 and 50 years old, have a sedentary lifestyle and elevated blood pressure, and have been born in the United States to either two African American or two non-Hispanic Caucasian parents.
