Association between dynamic muscle strength and functional performance tests, SF-36 subscale and fatigue score

Dependent variable	Independent variable	$$\widehat{\mathit{\beta }}$$	Standard error	R2	P-value
1-RM-total, kg	Role-physical functioning (SF-36)	-0.38	0.09	0.14	< 0.001
	Handgrip test	2.09	0.61	0.22	0.0027
	Role-emotional functioning (SF-36)	0.23	0.08	0.34	0.0125
	Timed chair-stand test	1.61	0.53	0.42	0.0065
	Fatigue (FSS)	-9.80	4.13	0.52	0.0218

$$\widehat{\beta }$$

= parameter estimate, R² = coefficient of determination; 1-RM = one repetition maximum is the largest possible load of a particular movement; 1-RM -total = sum of total load lifted in the 1-RM tests (i.e., leg press, leg extension, leg curl, chest press, and lat pulldown); SF-36 self-administered health questionnaire - Short Form Health Survey 36, FSS fatigue severity scale.
