Prediction of one repetition maximum strength from multiple repetition maximum testing and anthropometry

What this work gives Aellic

70 subjects aged 18–69, bench press and leg press at 1, 5, 10 and 20RM. The load-repetition relationship is curvilinear, not linear (bench press linear Sy.x = 2.6 kg versus non-linear 0.2 kg; leg press 11.0 versus 2.6 kg), and accuracy falls as the repetition count rises (R² for 5/10/20RM: bench 0.993/0.976/0.955, leg press 0.974/0.933/0.915). Concludes verbatim: “no more than 10 repetitions should be used in linear equations to estimate 1RM”. This is the source of Aellic's 10-repetition cap.
