Regression models for RPE and muscle pain during exercise

Outcome variable	Predictor(s)	Adj. R2	P	B	SE B	β	P
Average RPE		0.20	<0.01
	iv-PCS			0.15	0.05	0.34	0.008**
	PCS			0.09	0.03	0.32	0.02*
	TMD			−0.02	0.01	−0.23	0.07
Average muscle pain		0.20	<0.001
	iv-PCS			0.21	0.05	0.48	0.0002***
	TMD			−0.02	0.01	−0.22	0.08

iv-PCS = in vivo “situational” catastrophizing; PCS = Pain Catastrophizing Scale; RPE = ratings of perceived exertion during exercise; TMD = total mood disturbance.

^*Predictor is significant at the 0.05 level.

^**Predictor is significant at the 0.01 level.

^***Predictor is significant at the 0.001 level.
