What´s new in JSAMS 2023?From time to time it is necessary to adapt journal structures to recent developments within the scientific community. Like many other disciplines, sports medicine and sport science are facing enhanced reporting requirements for scientific publications, expressed in consented guidelines like the CONSORT statement ( http://www.consort-statement.org/media/default/downloads/CONSORT%202010%20Checklist.pdf ). Following them properly, however, may lead to difficulties with low word limits. So far the JSAMS limit was set at 3,000 for original research, and it has probably served well to facilitate concise writing.
Physical activity across the lifespan: the need for a gender perspectiveFor the November issue, I would like to highlight three papers addressing the topic of physical activity. In the past decades, there has been an increasing interest in physical activity research, with a shift from emphasizing aerobic exercise to the broader concept of physical activity for various health benefits6. Physical activity guidelines describe how much physical activity at a moderate-to-vigorous intensity (MVPA) is needed to achieve these beneficial health effects. Generally, less females than males comply with physical activity guidelines: 85% of girls and 78% of boys, and 32% of women and 23% of men4,5.
Two "hot topics" addressed and one article about "unknown territory"For our October issue, it is my pleasure to highlight three papers from Denmark, Australia and Canada. Two of them address research questions from heavily debated areas (use of non-steroidal antiinflammatory drugs, NSAIDs, by athletes4 ; management of head injuries 5) whereas the other one is from an underresearched field (sport and gastrointestinal problems1).
Prevalence, frequency, adverse events, and reasons for analgesic use in youth athletes: A systematic review and meta-analysis of 44,381 athletesTo identify the prevalence, frequency, adverse effects, and reasons for analgesic use in youth athletes.
The reduction of sport-related fatal incidents is an ongoing task for sport physiciansThe survived cardiac arrest of Christian Eriksen during the European Football Championships 2020 (postponed to 2021 due to the pandemic) has shown once again that even the seemingly healthiest athletes who perform at the highest level are not immune to cardiac disease and even sudden cardiac death. Although fortunately rare, such cases are always threatening and have the potential to impair the reputation of sport despite "contradictory" findings like the ones from Orchard et al.4 in this issue who report a reduced death rate compared to the general population even in a contact sport like Australian Rules Football when played on elite level.
Developmental associations of accelerometer measured moderate-to-vigorous physical activity and sedentary time with cardiorespiratory fitness in schoolchildrenThis study examined the developmental associations of accelerometer-based moderate-to-vigorous physical activity (MVPA) and sedentary time (ST) with cardiorespiratory fitness (CRF) in schoolchildren.
Applying an ecosystem approach to explore modifiable factors related to the risk for low motor competence in young childrenEarly childhood is a crucial phase for motor development in which differences between children can manifest. These differences might be related to factors in ecosystems in which children are raised, of which little is currently known. The current study's purpose was to explore which modifiable factors in children's ecosystems are associated with the odds for low versus higher motor competence (MC) in 4- to 6-year-old children.
Association of handgrip strength with all-cause mortality: a nationally longitudinal cohort study in ChinaHandgrip strength is considered a vital and reliable measure of comprehensive physical assessments, whereas the association of handgrip strength with overall mortality risk among Chinese adults was less studied.

Return to exercise post-COVID-19 infection: A pragmatic approach in mid-2022With over half a billion cases of COVID-19 reported globally since December 2019, medical knowledge of COVID-19, its mode of transmission, clinical manifestations and possible long-term complications has increased significantly. Advice regarding investigation, management and return to exercise has also changed over this time in line with emerging evidence, vaccine distribution and the features of new variants. This editorial seeks to synthesize the current knowledge on return to exercise following COVID-19 infection, based on current scientific literature and real-world experience.
Low energy intake (RED-S), hamstring injuries in cricketeers and exercise during pregnancy - relevant (clinical) topics from sports practiceThis issue of JSAMS features several articles with high practical relevance of which I would like to highlight three:
Comparison of different test protocols to determine maximal lactate steady state intensity in swimmingThis study compared step test, lactate minimum (LM) test and reverse lactate threshold (RLT) test protocols with maximal lactate steady state (MLSS) in free-swimming. All test protocols used fixed duration increments and high work-rate resolution (≤ 0.03 m·s−1) to ensure high sensitivity.
What are the employment prospects for Australian Sport Scientists?The most recent unemployment figures released on April 14th show that only 4% of the labour force across Australia was unemployed in March 2022.1 But what are the employment prospects for Australian Sport Scientists entering in the labour force now and in the future? No doubt the industry was disrupted over the past 2 years since the onset of the COVID-19 pandemic, but the accreditation standards set forth by Exercise Sport Science Australia (ESSA) that have been adopted by Australian Universities when training their sport science students should have ensured the development of a rigorous set of graduate skills and qualities, which in many cases can be transferrable to a variety of settings.
Neck strength and concussion prevalence in football and rugby athletesTo determine the maximal isometric neck strength of male and female rugby and football (soccer) athletes, and to investigate the relationship between neck strength and sport played, sex, age, anthropometric measurements and concussion history.

Mental health impact on at-risk high-level athletes during COVID-19 lockdown: A pre-, during and post-lockdown longitudinal cohort study of adjustment disorderWe read with great interest the July issue of the Journal of Science and Medicine in Sport regarding the impact of the COVID-19 pandemic on athletes. In that issue, Pillay et al.1 reported that 52% of athletes felt depressed during the lockdown period. There is, however, a lack of baseline data hindering the comparison of these findings to the pre-pandemic prevalence. This prompted us to do an early analysis of our ongoing longitudinal cohort study examining Adjustment Disorder (AjD) in Australian high-level athletes.

Will the real leaders please stand up? The emergence of shared leadership in semi-professional soccer teamsHigh-quality leadership is often regarded as one of the main sources of competitive advantage. Especially within sport teams, a team’s leadership structure has historically been considered to be stable across the season, with the coach and team captain as the formal, and often sole, leaders. In line with recent organizational research, the present study aims to broaden this perspective by also taking informal leaders into account and exploring how leadership structures among athletes within sport teams evolve over the course of a season.

A deep dive into testing and management of COVID-19 for Australian high performance and professional sportThe purpose of testing for any communicable disease is to support clinicians in the diagnosis and management of individual patients and to describe transmission dynamics. The novel coronavirus is formally named SARS-CoV-2 and the clinical disease state resulting from an infection is known as COVID-19. Control of the COVID-19 pandemic requires clinicians, epidemiologists, and public health officials to utilise the most comprehensive, accurate and timely information available to manage the rapidly evolving COVID-19 environment.
The Australian Institute of Sport framework for rebooting sport in a COVID-19 environmentSport makes an important contribution to the physical, psychological and emotional well-being of Australians. The economic contribution of sport is equivalent to 2–3% of Gross Domestic Product (GDP). The COVID-19 pandemic has had devastating effects on communities globally, leading to significant restrictions on all sectors of society, including sport. Resumption of sport can significantly contribute to the re-establishment of normality in Australian society. The Australian Institute of Sport (AIS), in consultation with sport partners (National Institute Network (NIN) Directors, NIN Chief Medical Officers (CMOs), National Sporting Organisation (NSO) Presidents, NSO Performance Directors and NSO CMOs), has developed a framework to inform the resumption of sport.
