Why the study?
Does high-intensity aerobic interval training result in greater beneficial adaptation of the heart compared to low-to-moderate exercise intensity?
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.
Supports hypothesis of superior cardiac adaptation with high-intensity training; hypothesis-generating and requires randomized trials before practice change.
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.
