Strength and muscle thickness changes.

Variable	P-value	Size of effect (mean ± 90% CL)	Chance of RPE-loading advantage (≥0.20 ES) (%)	Chance of trivial difference (−0.19 to 0.19 ES) (%)	Chance of %1RM-loading advantage (≥0.20 ES) (%)
Squat 1RM	0.32	0.50 ± 0.63	79	18	4
Bench 1RM	0.52	0.28 ± 0.73	57	29	14
Combined 1RM	0.38	0.48 ± 0.68	72	22	6
PMT	0.66	0.15 ± 0.79	46	32	22

VLMT70	0.79	−0.06 ± 0.68	25	38	37

Between group differences in strength and muscle thickness. CL, confidence limit; RPE, rating of perceived exertion; ES, effect size; 1RM, one repetition maximum; PMT, pectoralis major muscle thickness; VLMT50, vastus lateralis muscle thickness at 50% femur length; VLMT70, vastus lateralis muscle thickness at 50% femur length.
