abstract="OBJECTIVES: (1) To establish the reference values of the test of 'Position of hip passive resistance against gravity' (PHPR) in young athletes; (2) To investigate differences between the values of PHPR test according to athlete's sex, age and sport practiced. DESIGN: Cross-sectional. SETTING: Sports club. PARTICIPANTS: 282 Volleyball, basketball and futsal athletes aged between 10 and 18 years. MAIN OUTCOME MEASURES: Hip passive stiffness was measured through PHPR test, which provides indirect information regarding this tissue property; high stiffness means low corresponding test values. RESULTS: The mean values of PHPR test ranged from 0.41 to 1.06°/kg. The test results were different among all age categories and the values were lower in older athletes (p<0.001). The PHPR test values of futsal players were lower than basketball players only in the intermediate age category (p=0.001). The female volleyball athletes had higher values than the male ones (p<0.001). CONCLUSION: This study established reference values for PHPR test in young athletes, which allow therapists to obtain information regarding hip passive stiffness by means of a clinical test. Hip passive stiffness in young athletes increases with age, and female volleyball players showed lower values of this property compared with males.<p /> <p>Language: en</p>",
