title: Head-first versus feet-first sliding: a comparison of speed from base to base.
abstract: BACKGROUND
  Two basic baseball sliding techniques, feet-first and head-first, are taught at all levels of play. Because of the risk for injury to the upper extremities and the cervical spine during head-first sliding, it is potentially more dangerous than feet-first sliding. There is an assumption among coaches that head-first sliding is more aggressive and faster, but there has been no scientific study to prove this claim.
  
  
  OBJECTIVE
  The purpose of this study was to determine which technique provides a faster slide into the base.
  
  
  METHODS
  Controlled field study.
  
  
  METHODS
  A total of 60 players ranging from Little League to college level was analyzed. Each athlete was evaluated three times from a standing start at first base to either a head-first or feet-first touch of second base. Each athlete was also timed in a 40-yard sprint and his or her preferred sliding technique was recorded.
  
  
  RESULTS
  We found no statistically significant difference in speed between head-first and feet-first sliding at all levels of play in this study.
