Why the study?
Repetitions in reserve (RIR) relies on estimation, and it was unclear how an individual's relative and absolute strength affect loading choices for a given RIR.
An athlete's absolute and relative strength is strongly inversely associated with their loading choices when using repetitions in reserve, indicating strength levels may influence RIR estimation.
May warrant strength-specific RIR load adjustments in athletes; extends evidence on factors affecting autoregulation accuracy.
