The results revealed that logistical support from parents had not only a direct positive association with overall MC, both for girls and boys, but also with most of the FMS categories.

While time spent in sports or coach-/instructor-led physical activities had a significant SEM generated direct effect only for boys' MC and for locomotor, upper body object control and balance, the aesthetic design of the school grounds was only associated with girls' MC and those same three FMS categories.

The negative consequences of physical inactivity on health are profound, as they threaten to persist into adulthood, exacerbating the burden of preventable health issues. There is persuasive evidence that vigorous PA generates physical fitness and health benefits surpassing those of low- or moderate-intensity activity in youth. In addition, indications show that the adherence rate to vigorous PA among youth exceeds that relative to for low- or moderate-intensity activity. As a result, promoting vigorous PA can help mitigate the global issue of low adherence to PA in youth. Therefore, in this Current Opinion paper, we argue that vigorous PA, compared to low or moderate-intensity activity, holds greater significance for youth's health and physical fitness.

However, heterogeneity in study design, participants, and recovery outcomes has led to mixed findings. Further work is needed to evaluate potential differences by sex and to investigate the role of related characteristics, such as sport contact-level, in recovery timelines. This study aimed to investigate whether concussion recovery trajectories differ by sex, considering a priori clinical and demographic covariates, and accounting for the sequence of recovery outcomes. Our secondary question was whether sport contact-level modifies the relationship between sex and time to outcomes. Using data from the Ivy League-Big Ten Epidemiology of Concussion Study, we included SRCs reported across five academic years; 2015-2020 (February 2020). We used Cox proportional hazards regressions to estimate associations between sex and time from injury to three outcomes: (1) symptom resolution, (2) return to academics, (3) return to full play, accounting for measured confounders.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Among 1160 SRCs (male, n = 667; female, n = 493) with complete data, median age overall was 20 years (25th-75th percentiles:19-21), and most occurred among athletes playing high-contact sports (78.0%). Males were slightly more likely to complete symptom resolution over time compared to females (HR = 1.18, 95%CI = 1.05-1.33), but results were attenuated in fully adjusted models (HR 1.13, 95%CI = 0.99-1.29). Similarly, the HR of full academic return for males compared to females was 1.22 (95%CI = 1.07-1.38), but was attenuated in fully adjusted models (HR = 1.11, 95%CI = 0.97-1.28). The HR of full return to play for males compared to females was 1.14 (95%CI = 1.02-1.28), and was attenuated after adjustment (HR = 1.06, 95%CI = 0.93-1.20) as well. The interaction between sex and playing a high/low-contact sport was not statistically significant across models, though differences were apparent.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;Among a cohort of collegiate athletes with SRC, recovery timelines appeared similar between male and female athletes, adjusting for measured confounders.

Given that injury prediction is an emerging topic within sport, the increasing interest and excitement towards complex machine learning algorithms within this space is a cause for concern when fundamental principles of prediction model development are not followed. As such, we feel the need to intervene and highlight methodological and conceptual inaccuracies.&lt;/p&gt;&lt;p&gt;The models presented in this paper were deemed by the authors to be “quite sound” [1]. However, this is not true, as recently highlighted in the systematic review in Sports Medicine [2]. All of these models were included in this systematic review, and after evaluation with the established Prediction Model Risk of Bias Assessment Tool (PROBAST) [3], were rated as high or unclear risk of bias [2].&lt;/p&gt;&lt;p&gt;The authors detail that, “the use of machine learning has great potential to unearth new insights into the workload and injury relationship.”[1] Prediction models may use both causal and non-causal predictors to estimate the risk of a future outcome [4, 5]. Consequently, it is inappropriate to use the included predictors to infer causal relationships between individual predictors and the outcome [6, 7]. Further, the authors state that Shapley values, local interpretable model-agnostic explanations, and partial dependency plots can be used to assist in interpreting cause-effect relationships with machine learning models [8]. These tools assess for associations between predictors and outcomes and, regardless of how these methods are labelled, the popular adage “correlation is not causation” still holds [8]. Importantly, these methods remain explorative, provide post hoc explanations (rationalization), and require confirmatory studies.&lt;/p&gt;&lt;p&gt;Such inaccurate and incorrect interpretations of clinical prediction models are of particular concern. This is because they can lead practitioners to attempt to change injury risk by intervening or manipulating predictor variables under the false assumption of a causal relationship; while these strategies are likely ineffective, they also have potentially harmful consequences for the athlete [4, 5, 9].&lt;/p&gt;&lt;p&gt;While the authors promote balancing dataset outcomes through over and under-sampling [1], this is highly discouraged as ‘balancing’ datasets alters the outcome prevalence, biasing towards overestimating risk.[10, 11] Balancing data without appropriate recalibration can inappropriately impact risk prediction and ultimately decision-making [11]. The authors also encourage creating classification models. Classification models are not recommended as this supersedes clinical and performance decision-making from the model users [11]. Classification models do not allow situational context and assume all situations and individuals have the same risk threshold.

Variations in step width may impact the lower limb biomechanics. This systematic review aimed to synthesize the published findings to determine the influence of acute changes in step width on locomotion biomechanics and provide implications for injury prevention and enhanced sports performance. Literature was identified, selected, and appraised in accordance with the methods of a systematic review. Four electronic databases (Web of Science, MEDLINE via PubMed, Scopus, and ScienceDirect) were searched up until May 2023 with the development of inclusion criteria based on the PICO model. Study quality was assessed using the Downs and Black checklist and the measured parameters were summarized. Twenty-three articles and 399 participants were included in the systematic review. The average quality score of the 23 studies included was 9.39 (out of 14). Step width changed the kinematics and kinetics in the sagittal, frontal, and transverse planes of the lower limb, such as peak rearfoot eversion angle and moment, peak hip adduction angle and moment, knee flexion moment, peak knee internal rotation angle, as well as knee external rotation moment. Alteration of step width has the potential to change the stability and posture during locomotion, and evidence exists for the immediate biomechanical effects of variations in step width to alter proximal kinematics and cues to impact loading variables. Short-term changes in step width during walking, running, and sprinting influenced multiple lower extremity biomechanics. Narrower step width may result in poor balance and higher impact loading on the lower extremities during walking and running and may limit an athlete’s sprint performance. Increasing step width may be beneficial for injury rehabilitation, i.e., for patients with patellofemoral pain syndrome, iliotibial band syndrome or tibial bone stress injury. Wider steps increase the supporting base and typically enhance balance control, which in turn could reduce the risks of falling during daily activities. Altering the step width is thus proposed as a simple and non-invasive treatment method in clinical practice. Short-term changes in step width during gait could influence multiple lower extremity biomechanics. Increasing step width may be beneficial for specific injury rehabilitation. Wider steps increase the supporting base and typically enhance balance control to reduce the falling risks.
