Yoga Training and Retinal Vasculature

The Impact of Yoga Training Protocols on Cognition, Aerobic, and Neuromuscular Performances, and Retinal Microvasculature and Microcirculation in Older Persons.

This study will compare the impact of a novel high-speed, cued yoga program to a standard yoga program on retinal microvasculature, cognition and neuromuscular function.
