Sprints change blood molecules linked to heart and metabolic health
Technology
Quick science update: sprinting isn't just good for your fitness: it actually changes your blood.
Researchers from the US Australia, and Sweden compared six short, all-out sprints (with breaks) to a long, steady cycling session.
Turns out, those intense bursts triggered major shifts in molecules linked to heart and metabolic health.
Sprints affect fat tissue differently
The sprint group's blood even affected fat tissue differently than moderate exercise, something pretty unique.
While HIIT is efficient, it's not for everyone; older or less-fit people might need gentler options.
Lead researcher Dr. Paul Cohen says this study could help create more personalized workouts based on how our bodies respond.
