title: [The effect of different types of sports and athletes' age on the pathological changes of the musculoskeletal system].
abstract: OBJECTIVE
  Our aim was to determine the most common musculoskeletal diseases, depending on the type of sports and athletes' age.
  
  
  METHODS
  The results of examination of 976 athletes aged from 16 to 42 years (average age - 28,9±2,3) with musculoskeletal diseases were analyzed. Medical diagnostic procedures included clinical, laboratory, instrumental (radiography, magnetic resonance imaging, ultrasound) investigations and functional testing (goniometry, manual muscle testing).
  
  
  RESULTS
  Majority of patients were diagnosed to have diseases of the knee (17.9%) and ankle joints (11.3%), the heel bone (12.9%), Achilles tendon (10.2%), post-traumatic musculoskeletal diseases (16.2%), degenerative-dystrophic diseases of the spine (12.8%). In the young age group (16 to 20 years) post-traumatic disorders were most common. In the middle-age group (21 to 30 years) along with post-traumatic disorders diseases of the knee frequently occurred. For athletes over 30 years old, along with diseases of the knee spinal diseases were found to occur 2-3 times more frequently in comparison with other age groups. Injuries which are more common for different types of sports were identified: acute traumas - competitive sports, diseases of the calcaneus - sports with running and jumping (athletics, volleyball, soccer), disease of ankle joints - sport with sharp change in movement direction (hockey, figure skating), disease of the knee - sports with high load of the knee joint (figure skating, gymnastics, volleyball, diseases of bones and joints of the upper extremity - tennis, disease of spine - weightlifting.
  
  
  CONCLUSIONS
  pathological changes in the musculoskeletal system depend on the type of sports and the age of athletes. The combination of age and risk factors associated with type of sport increases the possibility of development of these diseases of the musculoskeletal system.
