​​​​Welcome to our July 2018 Issue of the Clinical Journal of Sport Medicine.  

With all the excitement of the 2018 FIFA World Cup in Russia now well underway and close to reaching it's conclusion, we bring you a great line-up of Original Research this Issue, kicking off with an article from Owoeye and colleagues on the prevention of ankle sprains in youth soccer and basketball using a neuromuscular training program, and an analysis of risk factors for these troublesome injuries. 

In a secondary analysis of pooled data from 5 different studies, 188 injuries from 171 players (male and female, aged 11-18 years) were reported, with evidence of a protective effect of neuromuscular training programmes on risk of injury. Risks were found to be higher amongst basketball players, and those with a previous history of ankle injury. 

Whilst conventional ultrasound is cheap and often readily available pitch-side or at the training ground, the sensitivity and specificity of this modality for low-grade muscle injuries is considered to be lower than that of MRI. 

Interestingly in this study, all 
Grade I injuries, accounting for 47% of all injuries amongst the cohort, were undetectable by conventional ultrasound, but were all identified using contrast enhanced ultrasound. The authors conclude that this new diagnostic modality is superior to conventional ultrasound in the diagnosis of low-grade muscle injuries.  

There is much in the media on the (ab)use of marijuana amongst sports participants, and the debate on whether or not marijuana should be on the WADA list of banned substances. Some individuals use this drug for recreational purposes, some for a therapeutic effect, and some for a belief that the drug carries a performance-enhancing effect for some sports in some situations. 

Trinh and colleagues present a systematic review on the subject of marijuana and its effects on athletic performance. They conclude that, from the available evidence, there is a lack of data to either confirm or deny a significant effect of marijuana on performance in sport and call for more high quality studies on the topic in order to inform doping policy in the future.
