The Claim

Prediction accuracy in resistance exercise improves slightly when predictions are made closer to the point of task failure, with a reduction in underprediction of 0.025 repetitions per unit of proximity.

Supports is higher

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

In plain English

When people estimate how many more repetitions they can perform during resistance exercise, their estimates become more accurate the closer they are to reaching physical failure, with a consistent reduction in underestimation of 0.025 repetitions for each unit of proximity to failure.

See the scientific wording

Prediction accuracy in resistance exercise improves slightly when predictions are made closer to the point of task failure, with a reduction in underprediction of 0.025 repetitions per unit of proximity, suggesting temporal proximity enhances self-monitoring precision.

Why this might work

As a muscle approaches failure, sensory signals from fatigued muscle fibers and joint receptors become stronger and more frequent, allowing the brain to more accurately sense how much effort is left and how many more repetitions can be completed.

    When people guess how many more reps they can do right before they can't do another one, they're more accurate than when they guess at the start. The closer they are to quitting, the better their guess gets.
