The Claim

In moderately active young adults, sprint interval training (SIT) results in greater reductions in neuromuscular performance—specifically in counter movement jump height, squat mean power, and bench press peak power—compared to both work-matched burpee interval training (BIT) and vigorous intensity continuous training (VICT), with performance declines of 1.2 cm in jump height, 1.7 W/kg in squat power, and 0.7 W/kg in bench press power observed after a single 9-minute session.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Quantitative
1 study reviewed
In plain English

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.

  1. Study: Sprint Interval Training Attenuates Neuromuscular Function and Vagal Reactivity Compared With High-Intensity Functional Training in Real-World Circumstances

    The study shows that a short, intense sprint workout reduces muscle performance more than other similar workouts, and the drops in jump and power performance match exactly what the claim says.
