- For 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.
- 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).
- To identify the prevalence, frequency, adverse effects, and reasons for analgesic use in youth athletes.
- The 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.
- This study examined the developmental associations of accelerometer-based moderate-to-vigorous physical activity (MVPA) and sedentary time (ST) with cardiorespiratory fitness (CRF) in schoolchildren.
- Early 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.
