Numerous repetition prediction equations exist to estimate one-repetition maximum (1RM) bench press. Only one equation uses a two-load and repetitions-to-fatigue (RTF) approach to estimate 1RM bench press. However, it has not been vetted for accuracy. The purpose of the study was to assess the accuracy of two-load repetition equations to predict 1RM bench press in Division-II collegiate?women volleyball players. Players (n =13) performed RTF with loads in the 3-5 RTF range and 7-10 RTF range. On a separate day all player performed a 1RM bench press. 1RM predictions using the 2-load equation with one repetition reduction and the 2-load equation with no reduced repetition were not significantly different from actual 1RM. However, the no-repetition reduction equation had significantly less difference between predicted and actual 1RM (-0.2±3.8 kg) than the 1-load reduction equation (-1.5±3.3 kg). Further comparison of these equations with additional participants should be conducted to verify current findings.
