Description
Fraser Thurlow, Nicholas Cowley, Katie Slattery, and Jonathon Weakley offer, in a 2026 review, a pooled look at very short, hard bursts of interval training. Coaches use such short bouts a lot, but the instant load they place on the body is less clear than the load of longer sessions. The team asked what these bouts do to athletes right away, and what changes that load.
They searched three databases for studies of running-based short bouts in healthy athletes aged sixteen to forty. Forty-six studies gave 139 data samples. The pooled results cover heart rate, oxygen use, blood lactate, and how hard the session felt. The team also tested how session design, fitness, and level of play shifted those outcomes.
