The Claim

High-repetition resistance training increases perceived discomfort and pain, which results in an underestimation of proximity to muscular failure.

In plain English

When people perform resistance exercises with many repetitions, they feel more discomfort and pain, and as a result, they incorrectly believe they are farther from muscle failure than they actually are.

See the scientific wording

High-repetition resistance training increases perceived discomfort and pain, leading to underestimation of proximity to muscular failure.

Why this might work

When muscles are worked with many repetitions, waste products build up inside them and nerve signals become less efficient. This makes the muscles feel more burning and sore, and the brain interprets this as a sign to stop before the muscles are truly exhausted, even though more effort is still possible.
