title: The influence of age and physical activity on the pressure sensitivity of soft tissues of the musculoskeletal system.
abstract: BACKGROUND
  The pressure sensitivity of soft tissues is defined as the slightest pressure causing pain. Sex, movement system illnesses, pain ailments may influence the pressure sensitivity. However, there have been few studies on factors determining the level of pressure sensitivity of skeletal muscles.
  
  
  OBJECTIVE
  The authors have determined to study the influence of age and physical activity on the pressure sensitivity of skeletal muscles.
  
  
  METHODS
  The examination of pressure sensitivity of trigger points and muscle insertions was carried out using algometry.
  
  
  RESULTS
  76 volunteers (38 students and 38 individuals aged 50-75) participated in the study. The differences in pressure sensitivity between students and people aged 50-75 were not statistically significant. Pressure sensitivity of students differed depending on their level of physical activity.
  
  
  CONCLUSIONS
  The level of physical activity influenced the pressure sensitivity of skeletal muscles. Age did not significantly influence pressure sensitivity.
