The Journal of Physiology shows that nitrate improves function in the diaphragm, the muscle involved in coughing and breathing, by improving power. The study done in old mice, if replicated in humans, could provide a strategy for helping elderly people clear the lungs more effectively and avoid infection.
Previous studies showed nitrate was helping muscles by improving use of calcium in the muscle. This finding that it's additionally affecting power is significant, especially in the context of COVID-19, because the diaphragm is the primary inspiratory muscle used for breathing and coughing, the latter being relevant for clearing the lungs.
The research team at the University of Florida found that dietary nitrate supplementation elicited a pronounced increase in contractile function (power) of the diaphragm, a respiratory muscle, of old mice.
