Most of us have done it, right? Screening athletes for injury risk has become a normal part of our jobs as sport and exercise medicine clinicians. Why? Most likely because targeting high-risk athletes with individualised prevention programmes is an extremely attractive idea. Unfortunately, however, it may also be a misguided idea. Professor Roald Bahr illustrates just how unrealistic it is to identify which athletes will and will not get injured using current risk factor screening tests.1

Similarly, Wright et al2 highlight the inability of the extremely popular functional movement screen to predict injury. These papers challenge the entire concept of individually targeting high-risk athletes to prevent injury. We expect these papers to be real game changers—you will not screen without thinking about them.

So are standardised musculoskeletal assessments a waste of time? We think not. In fact, they remain a key element of our periodic health evaluations of Norwegian Olympic and Paralympic athletes. We perform musculoskeletal assessments to identify current ‘under-the-radar’ injuries, assess the rehabilitation status of previous injuries and establish future return-to-sport benchmarks for healthy athletes. Identifying who will get injured (and who will not) based on risk factor testing is wishful thinking for the foreseeable future. Nevertheless, when it comes to musculoskeletal screening, we urge readers not to throw the baby out with the bath water.

Much needed evidence on return to sport

Return to sport is a hot topic,3 yet in many cases the lack of high-quality research evidence to guide our decision-making can be extremely frustrating. That is why we expect the paper by Dr Hege Grindem et al4 to cause a huge splash. Their findings should give pause for thought to every athlete planning to return to high-level jumping, pivoting and cutting sports after ACL injury. The authors provide a strong case against premature return to sport, showing that, for every month of rehabilitation completed up to 9 months postinjury, the risk of reinjury falls by 51%. Clinicians seeking to put the brakes on overly enthusiastic athletes will certainly appreciate this quality evidence.

Prevention of common illnesses in sport—important! (for some)

The extent to which common illnesses such as upper respiratory tract and gastrointestinal infections pose a problem for athletes varies substantially between sports. In a recently-published study of football players in the Norwegian, Swedish and English Premier Leagues, Bjørneboe et al5 found that illness is only a minor contributor to the total health burden, with players getting sick on average once every two seasons. In contrast, surveillance data from the Norwegian Olympic and Paralympic team show that, in certain sports, such as swimming, rowing and cross-country skiing, common illnesses have a far greater impact on athletes' participation and performance than do injuries (unpublished data—for methods).6 In these sports, developing, testing and implementing illness prevention strategies should be among our main priorities.

Dr Ida Svendsen et al7 identified a number of risk factors for gastrointestinal and upper respiratory tract symptoms among elite cross-country skiers, such as season and competition period, training behaviours and international air travel. The authors suggest a number of novel prevention strategies, such as avoiding air travel immediately after racing, when athletes' immune function is already compromised. This practical suggestion should certainly be tested.

Come and join the herd

The 13th Scandinavian Congress of Medicine and Science in sports will be held this November at the beautiful Norefjell resort near Oslo. This fantastic congress, renowned for both its scientific and social programmes, is held in English and international guests are especially welcome. Do not forget your dancing shoes—or your hiking boots. Who knows, you might even spot one of the local reindeer herds, as did amateur photographer Arnhild Olsen, who snapped our beautiful cover image. We hope to see you there!
