Pre- and post-stretching values of hip hyperextension range of motion (ROM) for the stretching group (left panel) and the control group (right panel) throughout the 9 weeks of training and after 3 weeks of detraining (week 12). Results are presented as average for single and repeated bouts of stretching training legs. **: p < 0.001 from the corresponding pre-stretching value at week 0; §: p < 0.001 from the corresponding post-stretching value at week 0; †: p < 0.001 from the corresponding pre-stretching value at week 6; #: p < 0.001 from the corresponding post-stretching value at week 6.
