In this case-control study on 182 (288 hips) symptomatic (hip and/or groin pain >6 months and positive flexion-adduction-internal-rotation (FADIR) test) and 55 (110 hips) pain-free young football players (soccer or Australian football), femoral head cam morphology size defined using radiographic alpha angle was associated with MRI-defined cartilage defects and labral tears both in symptomatic and asymptomatic players, suggesting that cam morphology may contribute to the high prevalence of hip OA in football players.

This scoping review of 42 studies in PubMed, the Cochrane Library, MEDLINE, Embase and Web of Science until January 26, 2021, reports reference values for quadriceps and hamstring isokinetic and isometric strength tests in healthy athletes who play pivoting sports and athletes with anterior cruciate ligament reconstruction (ACLR) who play pivoting sports, including soccer, basketball and handball.

In this study, the creatine kinase blood concentration was analyzed 36-43 hours following to 70 official matches in 25 professional soccer players throughout a 3-year period. Individual absolute reference limits were calculated at 97.5th percentile of the samples collected, allowing for determining whether the creatine kinase response is typical or if it is higher than normal and could be used as a practical guide for detection of muscle overload, following professional soccer match-play.
