Effects of Inorganic Nitrate and Intensity of Exercise on Cardiovascular Health in Post-Menopausal Females

• Status: Recruiting
• Trial end date: 2023-03-01
• Target enrollment: 0
• Participant gender: Female

Summary

Post-menopausal females experience elevated cardiovascular disease risk (CVD), compared to premenopausal females and age-matched males. Current exercise guidelines appear inadequate to ameliorate this increased risk and higher intensity exercise may be necessary. Oral inorganic nitrate supplementation enhances both exercise performance and CVD risk profile in several clinical conditions. However, the effects of this intervention in post-menopausal females is unexplored.
