		PRE	POST	De-Tr	Interaction effect
DF ROM (°)	SS side	16.1 ± 4.5	21.8 ± 5.7^*	18.9 ± 7.4	F = 3.75, p = 0.036
DF ROM (°)	CON side	16.4 ± 4.7	16.2 ± 4.5	17.3 ± 6.4	η_p² = 0.211
Passive torque at DF ROM (Nm)	SS side	23.5 ± 5.6	30.1 ± 10.5^*	29.2 ± 10.7	F = 3.75, p = 0.036
Passive torque at DF ROM (Nm)	CON side	26.1 ± 8.6	25.7 ± 8.5	26.4 ± 6.0	η_p² = 0.211
Muscle stiffness (N/mm)	SS side	6.5 ± 3.8	3.7 ± 2.1^*	6.7 ± 8.6	F = 3.52, p = 0.043
Muscle stiffness (N/mm)	CON side	6.5 ± 6.1	6.5 ± 4.4	6.0 ± 8.5	η_p² = 0.201

Interaction effect for the comparison between intervention side (SS side) and control side (CON side) based on a two-way repeated measure analysis of variance on the right column. Before static stretching intervention program (PRE); after static stretching intervention program (POST); after detraining periods (De-Tr). Data presented as mean ± SD.

Significantly (p < 0.05) different form PRE value.
