Subjective evaluations of athletic performance are an important part of decision making across sporting organisations. Based on their expertise and intuition, coaches select their starting line-ups, scouts recommend or discourage teams from signing new potential players, and academy directors decide which players should move up or out of a team’s a...

Training load monitoring is a core aspect of modern-day sport science practice. Collecting, cleaning, analysing, interpreting, and disseminating load data is usually undertaken with a view to improve player performance and/or manage injury risk. To target these outcomes, practitioners attempt to optimise load at different stages throughout the trai...

The current technological age has created exponential growth in the availability of technology and data in every industry, including sport. It is tempting to get caught up in the excitement of purchasing and implementing technology, but technology has a potential dark side that warrants consideration. Before investing in technology, it is imperativ...

Background Preseason training develops players’ physical capacities and prepares them for the demands of the competitive season. In rugby, Australian football, and American football, preseason training may protect elite players against in-season injury. However, no study has evaluated this relationship at the team level in elite soccer. Purpose/Hy...

Aim To describe injury and illness incidence during the 2018 Winter Olympic Games (WOG) by Team USA. Methods A descriptive observational study. We used registered Team USA Olympic athletes’ electronic medical records to review preparticipation health histories and medical encounters immediately prior to and throughout the 2018 WOG. Medical encount...

The application of scientific principles to inform practice has become increasingly common in professional sports, with increasing numbers of sport scientists operating in this area. The authors believe that in addition to domain-specific expertise, effective sport scientists working in professional sport should be able to develop systematic analys...

Objectives To systematically identify and qualitatively review the statistical approaches used in prospective cohort studies of team sports that reported intensive longitudinal data (ILD) (>20 observations per athlete) and examined the relationship between athletic workloads and injuries. Since longitudinal research can be improved by aligning the...

Objectives: Player unavailability negatively affects team performance in elite football. However, whether player unavailability and its concomitant performance decrement is mediated by any changes in teams' match physical outputs is unknown. We examined whether the number of players injured (i.e. unavailable for match selection) was associated wit...

My first trip as a young sports medicine trainee to the Intercontinental Baseball Cup in Havana, Cuba. It was my very first baseball game, the first time I had to deal with an on-field artery injury and I even rescheduled my PhD defence because I felt that the trip was more valuable than the defence. Dear Hans, I know your parents emphasised the v...

Improving the lives of people with joint injury and osteoarthritis. I am idealistic and want to make a difference. Considering the organisational, financial and political barriers to change in healthcare, I realise that my obligation as a researcher is to work strategically and take every opportunity to promote evidence-based medicine. For the pas...

My fondest memories are the people I’ve worked with over the years. At the University of Washington (UW), Jon Drezner, John O’Kane, Ashwin Rao and Hank Pelto are terrific and drive me to be better. They make work fun and interesting and they push me to be better. It has been awesome to teach residents and fellows. I’ve appreciated the work I’ve bee...

My energy and drive have helped me overcome hurdles within SEM. My policy of strategic volunteering has been key. For instance, I am 27 years old and I have been to over 45 SEM conferences already. That provides a network that provides a lot of wisdom. At about 75% of the conferences I have gone for free (as I could not afford them) by serving drin...

Establishing the Athlete Welfare programme at the Olympic Games. I worked on this for many years—to see it implemented in Rio in 2016 was a real career highlight for me. I hope this will protect athletes in the future, and prevent harassment and abuse in all sports! …. Don’t ask!! ☺ Definitely the 2008 Olympic Games when I watched the inaugural 1...

Academically, finishing my PhD back in 2010 in Oslo, Norway. Sharing the moment with my family, friends and colleagues. As a sports physio, reaching the playoff finals of the Swiss Pro ice hockey championship with ‘my’ team (despite losing the Cup in game 7). My cousin Lucio (almost a brother for me), who played professional football (FC Servette...

Spikes in training and competition workloads, especially in undertrained athletes, increase injury risk. However, just as attributing athletic injuries to single risk factors is an oversimplification of the injury process, interpreting this workload-injury relationship should not be done in isolation. Instead, we must further unpack how (ie, throug...

The alarm rings, a much annoying sound. I sleepwalk, zombie like to the shower, where I spend the next 10 min failing to wake up. I grab a banana and a glass of orange juice as I pass through the kitchen, where one or more family members will usually be having a real breakfast. By consensus I have been requested to not speak to anyone at this stage...

Low-carbohydrate high-fat (LCHF) diets are a highly contentious current topic in nutrition. This narrative review aims to provide clinicians with a broad overview of the effects of LCHF diets on body weight, glycaemic control and cardiovascular risk factors while addressing some common concerns and misconceptions. Blood total cholesterol and LDL-ch...

Injury aetiology models that have evolved over the previous two decades highlight a number of factors which contribute to the causal mechanisms for athletic injuries. These models highlight the pathway to injury, including (1) internal risk factors (eg, age, neuromuscular control) which predispose athletes to injury, (2) exposure to external risk f...

Cost-benefit analysis is a term often heard in the world of economics. Businesses seek to maximise profits by comparing the costs and benefits of a proposed venture. Cost-benefit analysis is a valuable analytical technique that can also inform decisions in the clinical sports medicine setting.1 Specifically, cost-benefit analysis provides a useful...

Aim: To determine whether players who completed a greater number of planned preseason training sessions were more or less likely to be injured during the competitive season. Methods: A cohort of 30 elite rugby league players was prospectively studied during their 17-week preseason and 26-round competitive season. Injuries were recorded using a m...

As a medical student, I performed my scientific internship at the sports medicine department of The Hague Medical Centre in the Netherlands. I had the chance to complete a Randomised controlled trial (RCT) on the additional value of a night splint for patients with Achilles tendinopathy, which eventually resulted in a BJSM publication—that period w...

To increase, in our sample, the proportion of family physicians who provided their patients with written physical activity prescriptions after the delivery of a 3-hour educational workshop with the provision of practical tools to facilitate behaviour change. A pre-post study. Abbotsford and Mission, British Columbia. All 158 physicians registered w...

This article describes major topics discussed from the 'Economics of Physical Inactivity Consensus Workshop' (EPIC), held in Vancouver, Canada, in April 2011. Specifically, we (1) detail existing evidence on effective physical inactivity prevention strategies; (2) introduce economic evaluation and its role in health policy decisions; (3) discuss ke...
