Watch your speed: how fast you squat may tell you when to stop

Summary
This observational study tests whether the percentage of velocity lost during a set of Smith machine back squats can accurately predict how many repetitions remain before failure. Twenty-six resistance-trained men perform squats to failure under both constant-load and chain-based resistance. The goal is to see if velocity loss can serve as a practical tool for prescribing and monitoring training volume.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- variable resistance training (chains) and constant-load resistance training
- What this could lead to
- If the approach works, it could give trainers and athletes a precise, real-time way to prescribe squat volume without guesswork.
- What could go wrong
- This is a small, early feasibility study in experienced male lifters only. Results may not apply to other exercises, populations, or real-world gym settings.
