First seen Jul 22, 2026 · Last updated Jul 23, 2026 · Updated 1 time

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.
