https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6763680/ > HIIT (high-intensity interval training) and sprint interval training (SIT) for 6-8 wk increase VO2peak more than or at least comparable to MCT (moderate-intensity continuous training). > The clinical and physiological benefits of HIIT compared with those of MCT are shown in Table Table1.1. In multiple RCTs, a wide range of targets, including skeletal muscles[19-22], risk factors[21], vasculature[19-22], respiration[22,23], autonomic function[24], cardiac function[20,22,25-27], exercise capacity[26], inflammation[27], quality of life[27], physiological markers such as VO2peak, and endothelial function, showed better improvements with HIIT than with MCT. This is true even though the HIT groups were spending just minutes sprinting a few times a week, vs the MCT groups that spent 30 minutes to an hour running or jogging. |
