    Abstract:
    Inactivity causes muscle atrophy and capillary regression in skeletal muscle. Chlorogenic acid has an antioxidant capacity and may prevent capillary regression. Therefore, the protective effects of chlorogenic acid on inactivity-induced capillary regression in rat soleus muscle were investigated. Twenty male Wistar rats were randomly divided into four groups: control (CON), chlorogenic acid supplementation (CGA), 2-week hindlimb unloading (HU), 2-week hindlimb unloading plus chlorogenic acid supplementation (HU+CGA). The rats in CGA and HU+CGA groups were orally administrated chlorogenic acid (850 mg/kg/day). Unloading resulted in a decrease in capillary number, oxidative capacity, and an increase in oxidative stress of the soleus muscle, whereas chlorogenic acid supplementation prevented capillary and metabolic changes resulting from unloading by reducing oxidative stress. In conclusion, chlorogenic acid supplementation may qualify as an effective treatment to reduce capillary regression in skeletal muscle caused by disuse muscle atrophy.
