title: Assessment of adaptive changes of feet pressure distribution pattern amongst randomly selected group of female joggers.
abstract: BACKGROUND
  Both walking and running contain the same cyclical movement phases; however, they differ greatly in time proportions, as well as magnitude of acting forces. The objective of this study was to ascertain that the regular jogging activity induced the adaptive modifications of foot pressure distribution pattern in fore-aft and lateral-medial dimensions during walking for female joggers.
  
  
  METHODS
  The research base consisted of 96 women between 20 and 50 years of age, and included 50 female active joggers, and 46 of female non-joggers. The study was performed with the use of an EMED-SF force platform. Two parameters describing the plantar surface of the foot loading were established, namely force time integral (FTI) and pressure time integral (PTI). Two indicators were defined: percentage medial impulse acc. to Bowen and metatarsals and toes loading ratio acc. to Nagel.
  
  
  RESULTS
  Our study showed lower PTI and FTI for the both feet big toes in the female joggers group. What is more, our research results indicate that regular jogging increases loading of metatarsus and lateral side relatively to toes and medial side, respectively.
  
  
  CONCLUSIONS
  The observed differences in foot pressure distribution patterns in both groups included in the current study proved the substantial influence of jogging on adaptive functional changes of walking pattern.
