Background:Previousstudiesoffootstrikepatternsofdistancerunnersinroadraceshavetypicallyfoundthattheoverwhelmingmajorityofshodrunnersinitiallycontactthegroundontherearfoot.However,noneofthesestudieshasattemptedtoquantifyfootstrikepatternsofbarefootorminimallyshodrunners.Thisstudyclassifiesfootstrikepatternsofbarefootandminimallyshodrunnersinarecreationalroadrace.Methods:High-speedvideofootagewasobtainedof169barefootand42minimallyshoddistancerunnersatthe2011NewYorkCityBarefootRun.Footstrikepatternswereclassifiedforeachrunner,andfrequenciesofforefoot,midfoot,andrearfootstrikingwerecomparedbetweenthebarefootandminimallyshodgroups.Results:Atotalof59.2%ofbarefootrunnerswereforefootstrikers,20.1%weremidfootstrikers,and20.7%wererearfootstrikers.Forminimallyshodrunners,33.3%wereforefootstrikers,19.1%weremidfootstrikers,and47.6%wererearfootstrikers.Footstrikedistributionsforbarefootandminimallyshodrunnersweresignificantlydifferentbothfromoneanotherandfrompreviouslyreportedfootstrikedistributionsofshodroadracers.Conclusion:Footstrikepatternsdifferbetweenbarefootandminimallyshodrunners,withforefootstrikingbeingmorecommon,andrearfootstrikinglesscommoninthebarefootgroup.
