Oral administration of angiotensin‐(1–7) decreases muscle damage and prevents the fibrosis in rats after eccentric exercise

What is the central question of this study? Eccentric contraction exercises cause damage to muscle fibres and induce inflammatory responses. The exacerbation of this process can induce deposition of fibrous connective tissue, leading to decreased muscle function. The aim of this study was to examine the role of angiotensin‐(1–7) in this context. What is the main finding and its importance? Our results show that oral treatment with angiotensin‐(1–7) decreases muscle damage induced by eccentric exercise, reducing inflammation and fibrosis in the gastrocnemius and soleus muscles. This study shows a potential effect of angiotensin‐(1–7) for the prevention of muscle injuries induced by physical exercise.
