    <jats:sec> <jats:title>Background:</jats:title> <jats:p>Trail running has increased in popularity due to the benefits of physical activity in nature. However, trail running has an inherent risk of running-related injuries (RRI). It is known that athletes with certain psychological traits have a greater tendency to suffer injuries; however, this is unknown in trail runners. The main objective of this study was to identify trail runners’ psychological profiles and to compare the proportion of RRI across these profiles.</jats:p> </jats:sec> <jats:sec> <jats:title>Hypothesis:</jats:title> <jats:p>Trail runners with psychological profiles of high stress, precompetitive anxiety, mental fatigue, competitiveness, and poor sleep quality are at increased risk of RRI.</jats:p> </jats:sec> <jats:sec> <jats:title>Study Design:</jats:title> <jats:p>Prospective cohort study.</jats:p> </jats:sec> <jats:sec> <jats:title>Level of Evidence:</jats:title> <jats:p>Level 2.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods:</jats:title> <jats:p>A Gaussian mixture model cluster analysis was performed on 202 trail runners (55.5% male; aged 38.7 [33.4-46.2] years) with psychological stress, cognitive and somatic anxiety, self-confidence, mental fatigue, sleep quality, and competitiveness measured 4 weeks before participating in a race. The proportion of RRI during the race was recorded and compared across clusters.</jats:p> </jats:sec> <jats:sec> <jats:title>Results:</jats:title> <jats:p> Overall RRI proportion during competition was 11.3% (n = 24). The most common RRI were muscle (41.7%) and tendon/bursa (16.7%) injuries, affecting primarily the knee (33.3%) and lower leg (20.8%). Five psychological profiles were identified. Cluster 1 (competitive runners with moderate psychological stress and mental fatigue, low sleep quality and anxiety, and high self-confidence) had a higher RRI proportion than Cluster 3 (similar traits but lower psychological stress, mental fatigue, and higher self-confidence; 21.2% vs 3.2%; <jats:italic toggle="yes">P</jats:italic>  = 0.02). </jats:p> </jats:sec> <jats:sec> <jats:title>Conclusion:</jats:title> <jats:p>Certain psychological profiles in trail runners were associated with higher RRI risk.</jats:p> </jats:sec> <jats:sec> <jats:title>Clinical Relevance:</jats:title> <jats:p>The medical team or trail running coaches should monitor runners with psychological profiles with higher psychological stress, mental fatigue, and cognitive anxiety, as well as lower self-confidence and sleep quality, to design strategies to reduce their risk of RRI.</jats:p> </jats:sec>

    <jats:p> This study examined associations among training load (external and internal), heart rate variability (HRV), perceptual fatigue, sleep, and injury in endurance athletes during a 12-week training mesocycle. The aims were to (i) compare these parameters between injured and non-injured weeks and (ii) assess differences between high- and low-severity injuries. Fifteen endurance athletes (80% males; median age: 36.5 years; running experience: 5.5 years) participated. Injury severity was measured using the Oslo Sports Trauma Research Centre Questionnaire on Health Problems (OSTRC-H). Training load (training stress score [TSS], Session-Rate of Perceived Exertion [sRPE]), HRV, perceptual fatigue (readiness to train and wellbeing), and sleep were collected through daily and weekly assessments over 12 weeks. The weekly injury prevalence over the 12-week period ranged from 7%–40%, with 47% classified as high severity. Injured weeks were characterised by significantly higher sleep-related impairment ( <jats:italic>p</jats:italic>  = .004, Hedge's g = 0.704), while all other variables did not significantly differ. Athletes who sustained more severe injuries exhibited lower TSS ( <jats:italic>p</jats:italic>  &lt; .001, Hedge's g = 0.84), lower sRPE ( <jats:italic>p</jats:italic>  = .029, Hedge's g = 0.705), poorer subjective wellbeing ( <jats:italic>p</jats:italic>  = .003, Hedge's g = 0.753), and lower HRV ( <jats:italic>p</jats:italic>  = .059, Hedge's g = 0.487) in the week preceding the injury. This exploratory study provides preliminary insights into the potential role of sleep-related impairment, training load fluctuations, and HRV in injury severity among endurance athletes. While findings suggest benefits of integrating these measures into monitoring strategies, the small sample size limits generalisability and should be interpreted with caution. </jats:p>

    <jats:p>The continuous development in telecommunication tech­nologies has created opportunities for health professionals to optimise healthcare delivery by adopting digital tools into rehabilitation programs (i.e., telerehabilitation). These tech­nological advances, along with the demographic and social characteristics of each country, have made the implementa­tion of telerehabilitation a disparate process across regions. We have gathered the experience of four countries (Australia, Chile, Brazil, and Colombia) in two different regions (Ocea­nia and South America) to recompile the history pre- and post-Covid-19 outbreak until January of 2021, the barriers to, and facilitators of telerehabilitation, and outline the future challenges for these countries.</jats:p>

    <jats:p>Biomechanics as a discipline is ideally placed to increase awareness and participation of girls and women in science, technology, engineering, and mathematics. A nationwide Biomechanics and Research Innovation Challenge (BRInC) centered on mentoring and role modeling was developed to engage high school girls (mentees) and early-mid-career women (mentors) in the field of biomechanics through the completion of a 100-day research and/or innovation project. This manuscript describes the development, implementation, and uptake of the inaugural BRInC program and synthesizes the research and innovation projects undertaken, providing a framework for adoption of this program within the global biomechanics community. Eighty-seven high school girls in years 9 and 10 (age range: 14–16 y) were mentored in teams (n = 17) by women in biomechanics (n = 24). Using a design thinking approach, teams generated solutions to biomechanics-based problem(s)/research question(s). Eight key reflections on program strengths, as well as areas for improvement and planned changes for future iterations of the BRInC program, are outlined. These key reflections highlight the innovation, impact, and scalability of the program; the importance of a program framework and effective communication tools; and implementation of strategies to sustain the program as well as the importance of diversity and building a sense of community.</jats:p>

    <jats:p>Background/Objectives: Sitting is linked to health problems, including back pain. Sitting posture is commonly measured in the laboratory, but it remains unclear how this relates to real-world spine posture. Methods: A cross-sectional study of pain-free adults conducted measurements in “laboratory” and “real-world” settings. Wearable motion sensors recorded lumbar spine angular orientation to compare lumbar spine flexion angle during sitting postures in between settings. Gaussian mixture models defined participant-specific modes and overall probability distributions of real-world sitting posture. Measures included periods of real-world sedentary/activity behaviours and trunk postural control (laboratory). Results: Laboratory measures of lumbar angle were more flexed during questionnaire (30.0°) than upright (19.8°) sitting. The angle in unstable sitting was intermediate (27.1°). Spine posture in unstable sitting correlated with real-world overall mean posture (r = 0.49–0.54) and most frequent mode (r = 0.47). Upright laboratory sitting posture correlated with real-world second most frequent mode (r = 0.54). Sitting less (r = 0.45) and walking more (r = 0.41) in the real world related to better balance performance and lumbar spine coordination. Conclusions: Spine posture in an unstable sitting laboratory task had the closest association with real-world sitting but does not replicate the diversity of spine postures adopted in real-world sitting. Wearable sensors are viable to study real-world postures.</jats:p>
