Patients commonly present with generalized hip pain in the presence of normal radiographs, posing a diagnostic dilemma for physicians [1]. The hip is the essential and central component of movement between the torso and lower extremities and is integral to proper performance in almost all sports [2]. Thus, hip pain in the athlete, whether recreational or elite, presents a critical challenge to ...

*This table describes the situation for countries where most sporting participation opportunities are provided through community-based or recreational sporting organisations. It is acknowledged that some countries, like the USA, have sports delivery systems that are more likely to be linked to high schools or university colleges and so some of the opportunities for intervention may be different...

This is a retrospective case-control study of arthroscopic partial meniscectomy for isolated lesions of the lateral meniscus, performed between 1990 and 1995. Thirty-one knees were evaluated after an average follow-up of 8 years: 48.4% had excellent/good IKDC-scores and 64.5% excellent/good Lysholm scores. The Tegner activity score dropped from 7.2 (competitive sports) to 5.7 (recreational spor...

Distance running is among the fastest growing sports, with record registration to marathons worldwide. It is estimated that more than half of recreational runners will experience injuries related to the practice of their sport. Three-phase bone scintigraphy is a very sensitive tool to identify sports injury, allowing imaging of hyperemia, stress reaction, enthesopathy and fractures, often befor...

What is the role of physical activity in human capital accumulation? Brain research provides evidence of the importance of physical activity for cognitive functions. An increasingly sedentary lifestyle could thus disrupt human capital accumulation. We analyze effects of on-campus recreational sports and exercise on educational outcomes of university students. We randomize financial incentives t...

Introduction Commotio cordis is a term used to describe ventricular fibrillation (VF) triggered by a blunt, nonpenetrating blow, often the result of a small ball or puck hitting the chest in the course of recreational or competitive sports. It is typically fatal, though rates of successful resuscitation have improved in recent years. Experimental studies have identified a 10– 40-ms window durin...

BACKGROUND Autologous chondrocyte implantation (ACI) continues to technically evolve, but how the technical innovations affect the ability to participate in high-impact sports such as football is unknown. METHODS Clinical studies describing athletes treated with first-, second-, or third-generation ACI techniques were reviewed. The technical developments of ACI were evaluated, and the results...

BACKGROUND Physical activity (PA) is beneficial, enhancing healthy development. However, one-third of school-age children practicing sports regularly suffer from an injury. These injuries are associated with sex, chronological age, and PA level. PURPOSE To identify the importance of age, PA level, and maturity as predictors of injury in Portuguese youth. STUDY DESIGN Descriptive epidemiolog...
