title: The relationship between lower extremity injury, low back pain, and hip muscle strength in male and female collegiate athletes.
abstract: OBJECTIVE
  To determine the relationship of previous lower extremity (LE) injury and/or low back pain (LBP) on hip abduction and extension strength.
  
  
  METHODS
  Cohort study of college athletes at time of preparticipation screening physical.
  
  
  METHODS
  An NCAA Division I college.
  
  
  METHODS
  Two hundred ten college athletes (140 males and 70 females) from an NCAA Division I school.
  
  
  METHODS
  Mean and maximal hip abduction and extension strengths were recorded using a specially designed dynamometer anchoring station. Previous injury to the LE or LBP in the past year was recorded via personal interview at the time of screening and verified by review of previous injury records.
  
  
  RESULTS
  A significant difference in side-to-side symmetry of maximum hip extension strength was observed in female subjects who reported LE injury or LBP as compared to those who did not. Side-to-side difference in hip strength, however, did not differ between male athletes, regardless of reported LE injury or LBP status.
  
  
  CONCLUSIONS
  Female athletes appear to have a differing response of the proximal hip musculature to LE injury or LBP, as compared with their male counterparts. Research is under way to further validate these findings.
  
  
  CONCLUSIONS
  This study provides some reasoning to support the screening of hip strength during the preparticipation physical, as it may be important in the prevention of LE injury and LBP in collegiate athletes.
