Does high-intensity aerobic interval training result in greater beneficial adaptation of the heart compared to low-to-moderate exercise intensity?
This review summarizes epidemiological, experimental, and clinical evidence suggesting that high-intensity interval training provides greater cardiac adaptation than low-to-moderate intensity exercise.
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.
Wisløff et al. (Wed,) studied this question.
