     Reduced contact and flight times
     Increased mm activity during braking and pushing
     Hypothesizes enhanced storage of elastic energy in
      ankle extensors
   Running-related injury prevention through
    barefoot adaptations
   ROBBINS, STEVEN E.; HANNA, ADEL M.
     BAREFOOET RUNNING ELICITED CHANGES IN
      THE MEDIAL LONGITUDINAL ARCH.
     CHANGES ALLOWED DEFLECTION OF ARCH
      UPON LOADING
     CHANGES MAY BE DUE TO INNERVATION OF
      EPITHELIUM OF THE FOOT

    1. BOF, HIPS, SHOULDERS in alignment (no forward

    2. USE GRAVITY “FALL FORWARD”, lean forward
       to increase speed
    3. PULL, PULL, PULL!!! Actively use hamstrings to
       pull the foot off of the ground
    4. Avoid active landing. (Knee extension, heel strike)
       The quad should be relaxed during swing phase.
       Minimal cadence of 180 spm
