High-Intensity Interval Training to Maximize Cardiac Benefits of Exercise Training?

WISLOFF, U, O. ELLINGSEN, and O.J. KEMI. High-intensity interval training to maximize cardiac benefits of exercise training? Exerc. Sport Sci. Rev., Vol. 37, No. 3, pp. 139-146, 2009. We hypothesized that high-intensity aerobic interval training results in a greater beneficial adaptation of the heart compared with that observed after low-to-moderate exercise intensity. This is supported by recent epidemiological, experimental, and clinical studies. Cellular and molecular mechanisms of myocardial adaptation to exercise training are discussed in this review.
