Summary

This study looks at whether exercising in the morning or early evening makes a difference in lowering blood pressure and improving blood vessel health. Researchers will study 79 postmenopausal women aged 55-80 who have high blood pressure. Participants will be assigned to either a morning or evening exercise program, and their blood pressure and blood vessel function will be measured before and after training.
