		r	R2 (SEE)	p	Regression equation
Weight (kg)	First repetition	0.54	0.29(21.92)	<0.001	36.87+(13.62 × RISEscore)
Repetitions (number)	First repetition	0.61	0.37(3.66)	<0.001	16.70+(-2.77 × RISEscore)
MPV (m/s)	First repetition	0.63	0.40(0.10)	<0.001	1.02+(-0.08 × RISEscore)
	Last repetition	0.43	0.18(0.11)	<0.001	0.91+(-0.06 × RISEscore)

SEE: Standard error of estimation. RISEscore: Resistance Intensity Scale for Exercise's scores: 1 = easy, 2 = low, 3 = moderate, 4 = hard, 5 = maximal.
