Equations used to estimate one-repetition maximum data (1RM) and estimated 1RM data for the eccentric–concentric (Ecc-Conc) and concentric-only (Conc-only) bench-press (Grp—group average MVT based equation, OLS—ordinary least squares regression equation, LASSO—least absolute shrinkage and selection operator regression equation).
| Ecc-Conc | |
| Grp | 1RM = L-Vslope × MVT * + L-Vintercept |
| OLS | 1RM = L-Vslope × 0.543 + L-Vintercept × 1.250 − 3.721 |
| LASSO | 1RM = L-Vslope × 0.542 + L-Vintercept × 1.249 − 3.711 |
| Conc-only | |
| Grp | 1RM = L-Vslope × MVT * + L-Vintercept |
| OLS | 1RM = L-Vslope × 0.302 + L-Vintercept × 1.128 − 3.749 |
| LASSO | 1RM = L-Vslope × 0.299 + L-Vintercept × 1.125 − 3.735 |
L-Vslope—slope of the load–velocity profile; L-Vintercept—intercept of the load–velocity profile; MVT—minimum velocity threshold (i.e., velocity at 1RM); * Ecc-Conc: MVT = 0.17 m/s; Conc-only: MVT = 1.66 m/s.
