Sprint-interval training explained: a short-read preview of research-backed, time-efficient workouts that can boost aerobic fitness with minimal weekly time.
Key Takeaways
- A 2017 meta-analysis of 34 studies found sprint-interval training raised VO2 max by about 8% over up to 12 weeks.
- Two to three 20-second all-out sprints per session, three times weekly, produced 10–19% VO2 max gains in some studies.
- A target VO2 max near 49 ml/kg/min corresponded to lowest mortality in a large 2022 veteran cohort study.
