Summary

This study looks at whether adding a cocoa supplement to a regular exercise program helps older adults (55+) with slow walking speed improve their physical performance and muscle strength more than exercise alone. Participants will be randomly assigned to receive either cocoa or a placebo alongside their exercise routine. The goal is to find a simple, tasty way to boost the benefits of staying active.
