Changes in variables before and after stretching interventions.

	SS		HRS
	PRE	POST	PRE	POST
DF ROM (°)	30.9 ± 10.0	35.3 ± 10.8 **	31.7 ± 10.6	37.2 ± 11.1 **,#
Passive torque at DF ROM (Nm)	27.1 ± 14.1	27.7 ± 12.4	28.3 ± 12.0	29.7 ± 10.5
Muscle stiffness (Nm/cm)	17.3 ± 14.1	8.4 ± 6.3 **	17.3 ± 11.4	14.6 ± 11.8 §

^# = significant main effect. ^§ = significant interaction effect. ** p < 0.01; significantly different from PRE. SS, static stretching; HRS, hold–relax stretching; PRE, before stretching; POST, after stretching; DF, dorsiflexion; ROM, range of motion.
