Summary

This study looks at whether drinking beetroot juice before exercise helps post-menopausal women get more health benefits from their workouts. Beetroot juice is rich in nitrates, which the body turns into nitric oxide to improve blood flow. The researchers will measure changes in heart fitness, muscle strength, body fat, and overall physical function in 60 inactive women aged 50-70.
