Agreement between actual and predicted 1RM from different methods.

Method	1RM (kg, actual value: 140.2 ± 18.9)	ES (90%CI)	SEE (kg, 90%CI)	Pearson correlation (r)	slope	intercept
General MV	143.8 ± 19.7	0.19 (0.07; 0.31)	8.9 (7.7; 10.8)	0.88	0.847	18.321
General MPV	141.9 ± 19.3	0.09 (-0.01; 0.20)	8.2 (7.1; 9.9)	0.90	0.884	14.801
General PV	144.1 ± 19.1*	0.21 (0.11; 0.31)	8.0 (6.9; 9.7)	0.91	0.896	11.049
Individual MV	142.7 ± 20.3*	0.14 (0.07; 0.20)	4.8 (4.1; 5.8)	0.97	0.897	12.042
Individual MPV	140.9 ± 20.0	0.04 (-0.02; 0.10)	4.4 (3.8; 5.3)	0.97	0.917	11.022
Individual PV	143.7 ± 19.8**	0.19 (0.13; 0.24)	4.1 (3.5; 5.0)	0.98	0.929	6.651

Values are mean ± SD; MV: mean velocity; MPV: mean propulsive velocity, PV: peak velocity; General: data obtained from general equations; Individual: data obtained from individual equations; 1RM: one-repetition maximum; ES: effect size compared to actual 1RM values; 90%CI: 90% confidence interval; SEE: standard error of estimation; Pearson correlation, slope and intercept values were obtained from relationships between actual and predicted 1RM data. Significant differences compared to actual 1RM values:

* p < 0.05;

** p < 0.001.
