title: Is the rearfoot pattern the most frequently foot strike pattern among recreational shod distance runners?
abstract: OBJECTIVE
  To determine the distribution of the foot strike patterns among recreational shod runners and to compare the personal and training characteristics between runners with different foot strike patterns.
  
  
  METHODS
  Cross-sectional study.
  
  
  METHODS
  Areas of running practice in São Paulo, Brazil.
  
  
  METHODS
  514 recreational shod runners older than 18 years and free of injury.
  
  
  METHODS
  Foot strike patterns were evaluated with a high-speed camera (250 Hz) and photocells to assess the running speed of participants. Personal and training characteristics were collected through a questionnaire.
  
  
  RESULTS
  The inter-rater reliability of the visual foot strike pattern classification method was 96.7% and intra-rater reliability was 98.9%. 95.1% (n = 489) of the participants were rearfoot strikers, 4.1% (n = 21) were midfoot strikers, and four runners (0.8%) were forefoot strikers. There were no significant differences between strike patterns for personal and training characteristics.
  
  
  CONCLUSIONS
  This is the first study to demonstrate that almost all recreational shod runners were rearfoot strikers. The visual method of evaluation seems to be a reliable and feasible option to classify foot strike pattern.
