Table 4. Correlations between maximal isometric knee extension strength and motor imagery ability during PRE and for calculating the % of change.

Independent variables	Knee extensors strength (PC)
	r (p value)
Kineasthetic imagery ability (PRE)	-.021 (.946)
Internal visual imagery ability (PRE)	-.445 (.128)
External visual imagery ability (PRE)	-.411 (.163)
Kineasthetic imagery ability (%change)	.741 (.004)
Internal visual imagery ability (%change)	.623 (.023)
External visual imagery ability (%change)	.327 (.276)

Note: Bolded values represents a significant effect

PRE–measurement at baseline, PC–percent of change from pre to post; r–Person correlation coefficient.
