1:01Now PlayingScientists say people who participate in high intensity interval training, or HIIT, may reap benefits that aren’t seen with other forms of aerobic exercise, according to research published this month by a team of researchers at Rockefeller University.
The study shows high-intensity training provokes a robust response throughout the bloodstream. Participants completed either six all-out sprints on a bike for 30 seconds with a few minutes rest in between or a moderate-paced ride for 90 minutes. There were many more changes in proteins and other molecules in the high-intensity group. The researchers then compared some of those changes to a large database from the UK and found they were associated with better cardiovascular and metabolic health.
However, they emphasize the results come from young healthy adults and need to be confirmed in different populations and that the findings do not prove that high-intensity training is necessarily better.
