AB  - This study aimed to compare the cross-education effect of unilateral stretching 
      intervention programs with two different intensities (high- vs. low-intensity) on 
      dorsiflexion range of motion (DF ROM), muscle stiffness, and muscle architecture 
      following a 4-week stretching intervention. Twenty-eight healthy males were 
      randomly allocated into two groups: a high-intensity static stretching (HI-SS) 
      intervention group (n = 14; stretch intensity 6-7 out of 10) and a low-intensity 
      static stretching (LI-SS) intervention group (n = 14; stretch intensity 0-1 out 
      of 10). The participants were asked to stretch their dominant leg (prefer to kick 
      a ball) for 4 weeks (3 x week for 3 x 60 s). Before and after the intervention, 
      the non-trained leg passive properties (DF ROM, passive torque, and muscle 
      stiffness) of the plantar flexors and the muscle architecture of the 
      gastrocnemius medialis (muscle thickness, pennation angle, and fascicle length) 
      were measured. Non-trained DF ROM and passive torque at DF ROM were significantly 
      increased in the HI-SS group (p < 0.01, d = 0.64, 50.6%, and p = 0.044, d = 0.36, 
      18.2%, respectively), but not in the LI-SS group. Moreover, there were no 
      significant changes in muscle stiffness and muscle architecture in both groups. 
      For rehabilitation settings, a high-intensity SS intervention is required to 
      increase the DF ROM of the non-trained limb. However, the increases in DF ROM 
      seem to be related to changes in stretch tolerance and not to changes in muscle 
      architecture or muscle stiffness.
