POLICY WIRE — New York, United States — A new study has found that just three minutes of high-intensity sprinting may provide greater health benefits than a 90-minute moderate workout, based on changes in the bloodstream.

The research involved nearly 20 healthy men who completed 30-second sprints over a 23-minute session. Their blood samples showed a significant increase in molecules linked to improved muscle, liver, and immune function compared to those who cycled for 90 minutes.

Scientists observed an immediate surge in over 700 proteins associated with reduced risk of cardiovascular and metabolic diseases in the sprint group, while only seven such proteins changed in the cyclists during the activity. The findings suggest that intense exercise triggers a powerful molecular response, even after weeks of training, according to Dr. Paul Cohen of Rockefeller University.
