What type of training is known to increase nitric oxide secretion?

Aerobic training is known to increase nitric oxide secretion due to the sustained and rhythmic nature of the activity, which enhances blood flow and oxygen delivery to the muscles. This increased blood flow stimulates the endothelial cells lining the blood vessels to produce more nitric oxide, a vital signaling molecule that helps regulate vascular function, improve blood flow, and enhance nutrient delivery to tissues. Studies have demonstrated that consistent aerobic exercise can lead to adaptations in the vascular system that result in increased production and availability of nitric oxide, contributing to improved overall cardiovascular health and performance during both exercise and recovery periods.

While high-intensity interval training and plyometric training can also promote cardiovascular adaptations and may have some impact on nitric oxide levels, aerobic training is particularly effective due to its emphasis on prolonged moderate-intensity exercise, making it a cornerstone of developing nitric oxide pathways within the body. Weight lifting, generally characterized by short bursts of intense effort, induces a different physiological response that may not have the same impact on nitric oxide secretion as aerobic activities.
