Furthermore, a growing amount of evidence shows that HH wearing is associated with higher ground reaction forces (Ebbeling et al., 1994; Hong et al., 2005; Snow and Williams, 1994), indicating greater muscle and tendon forces, which may trigger tendon hypertrophy or improve its material properties.
