This study explores how cannabidiol (CBD), a compound from the Cannabis sativa plant, affects exercise performance and muscle function. The researchers wanted to see if CBD could improve endurance by changing gut bacteria. They found that CBD improved endurance and increased the presence of certain gut bacteria, including Bifidobacterium animalis, that may help muscles use energy more efficiently. The study involved treating mice with either CBD or B. animalis for 4 weeks and measuring their running ability on a treadmill. The researchers examined changes in muscle fibers and gut bacteria composition. They discovered that CBD and B. animalis increased oxidative muscle fibers, which benefit endurance performance. The results suggest that CBD enhances exercise performance by promoting beneficial gut bacteria and improving muscle energy use. The researchers conclude that both CBD and B. animalis could be used to boost endurance.
