Rockefeller University molecular biologists show that this intense exercise releases 100-fold more beneficial proteins into your bloodstream. Their study was published in the journal Cell Reports Medicine.

Researchers studied 19 young, healthy men who performed either six 30-second, all-out cycling sprints, just three minutes of intense effort, or 90 minutes of continuous moderate cycling. Immediately after the sprint workout, nearly 25% of the proteins measured in the blood had changed, compared with less than 0.25% after moderate cycling. More than 200 metabolites also changed after sprinting.

Many of the proteins activated by sprinting are involved in blood-vessel growth, tissue remodeling and communication between organs. When the researchers compared these proteins with health data from more than 53,000 people in the UK Biobank, they were associated with lower risks of obesity, type 2 diabetes, and other cardiometabolic diseases.

*These results shouldn’t drive you to perform only intense exercise. It does show that higher exercise intensity can dramatically change the biological signals and levels of beneficial proteins produced by exercise. It won’t hurt, though, to add these sprints to your routine in moderation if you are able.
