Surprising Findings
Burpees, despite being full-body and functional, caused far less cardiovascular strain and muscle fatigue than short sprints.
Many assume burpees are one of the most taxing exercises, but this study shows they’re significantly less intense on the heart and nervous system than all-out sprints—even with similar total time.
Practical Takeaways
Use sprint interval training strategically—not daily—due to its high neuromuscular and cardiovascular demand.

For young adults who exercise a bit, doing a quick 9-minute sprint workout leads to bigger drops in muscle power—like how high you can jump or how strong your legs and arms feel—compared to other similar workouts using burpees or steady hard exercise.
After a quick 9-minute workout, sprint intervals might make your heart take longer to calm down compared to burpees or steady hard exercise — at least in young, somewhat active people.
Sprint and hard steady workouts get your heart pumping faster and keep it near maximum longer than burpee workouts in young, somewhat active people — at least during 9-minute sessions.
Sprinting might help you stay younger on the inside by keeping your muscles, nerves, and metabolism in top shape.
