Researchers' Work from Xiamen University Focuses on Science and Technology (Low-intensity exercise training increases systolic function of heart and MHCII low cardiac resident macrophages).

A recent study conducted by researchers at Xiamen University in China explored the effects of low-intensity exercise training on cardiovascular health. The study focused on cardiac resident macrophages (cMacs), which play a crucial role in maintaining heart function. The researchers found that low-intensity exercise training resulted in an increase in the ejection fraction, a measure of systolic function, and a redistribution of cMac subsets. These findings suggest that exercise may have benefits for cardiovascular fitness by enhancing heart function and altering the distribution of cMacs. Further research is needed to fully understand the mechanisms behind these effects. [Extracted from the article]
