Low neuromuscular fitness is documented in adolescents with CHD and may be associated with clinical and morphological factors, indicating the need to assess strength in this population.

To evaluate neuromuscular fitness with a multifactorial approach and its associations with other clinical and morphological factors in adolescents with CHD.

This is an observational, cross-sectional study with adolescents with CHD, aged between 10 and 18 years. Neuromuscular fitness was calculated by the sum of the z-scores of four strength tests. Clinical factors of CHD were assessed by medical records and questionnaire. The morphological factors assessed were waist-to-height ratio, sum of skinfolds, and upper arm muscle area. Descriptive statistics, analysis of covariance, and linear regressions were performed.

Sixty adolescents with CHD participated, aged 12,7 ± 2,1 years, 55% girls. Maximum isometric strength was inadequate in 33%, jump height (power) in 33%, abdominal muscle strength resistance in 78%, and upper limb muscle strength resistance in 27%. Neuromuscular fitness was inadequate in 89% (n = 53) of adolescents with CHD. In the unadjusted regression, neuromuscular fitness was associated with arm muscle area (β = 0,12; p = 0,02; R2adj = 0,08) and in the unadjusted and adjusted regression it was lower in cyanotic (vs. acyanotic) CHDs (β = −1,76; p = 0,03 R2adj = 0,24).

The findings reveal deficits in different presentations of musculoskeletal strength in a large proportion of adolescents with CHD, reinforcing the need to measure fitness from a broader perspective. Low muscle mass and the presence of cyanotic CHD may imply in reduced neuromuscular fitness in adolescents with CHD.

A critical challenge for biomedical investigators is the delay between research and its adoption, yet there are few tools that use bibliometrics and artificial intelligence to address this translational gap. We built a tool to quantify translation of clinical investigation using novel approaches to identify themes in published clinical trials from PubMed and their appearance in the natural language elements of the electronic health record (EHR).

As a use case, we selected the translation of known health effects of exercise for heart disease, as found in published clinical trials, with the appearance of these themes in the EHR of heart disease patients seen in an emergency department (ED). We present a self-supervised framework that quantifies semantic similarity of themes within the EHR.

We found that 12.7% of the clinical trial abstracts dataset recommended aerobic exercise or strength training. Of the ED treatment plans, 19.2% related to heart disease. Of these, the treatment plans that included heart disease identified aerobic exercise or strength training only 0.34% of the time. Treatment plans from the overall ED dataset mentioned aerobic exercise or strength training less than 5% of the time.

Having access to publicly available clinical research and associated EHR data, including clinician notes and after-visit summaries, provided a unique opportunity to assess the adoption of clinical research in medical practice. This approach can be used for a variety of clinical conditions, and if assessed over time could measure implementation effectiveness of quality improvement strategies and clinical guidelines.

Medical advances in the management of CHD have shifted the focus from childhood mortality to life-long morbidity; therefore, clinical research in paediatric cardiology tends to replace mortality outcomes with functional and patient-reported outcomes. Despite these advances, the stratification of disease severity using a simple and reproducible CHD classification has not been established. The aim was to determine which classification best predicts functional status in children with CHD, in terms of cardiopulmonary fitness.

This retrospective cohort study was assessed from a cohort study of 296 children (mean age 11.3 ± 3.1 years, 129 female), who underwent a baseline and final cardiopulmonary exercise tests with a mean follow-up of 4.1 ± 1.6 years.

Seven CHD classifications were identified, assessing anatomical, physiological, therapeutic, or functional parameters in foetal, paediatric, or adult CHD populations. The four-stage paediatric CHD disease severity classification established by Uzark et al. best predicted functional status at the final cardiopulmonary exercise test assessment, with an area under the receiver operating characteristics curves of 0.62 (0.55–0.69) for impaired cardiopulmonary fitness (maximum oxygen uptake (VO2max) or ventilatory anaerobic threshold < −1.64 Z-score). The best inter-judge classification agreement was also observed for Uzark classification, with a Kappa coefficient of 0.88 (0.78–0.98).

The CHD classification by Uzark is reliable in terms of functional status prediction and reproducibility in children with CHD. This simple classification may contribute to identifying children with CHD most at risk of cardiopulmonary fitness impairment and initiating early preventive cardiovascular interventions in paediatric cardiology.

Preschooler inactivity and insufficient motor development have serious long-term consequences. The Chinese Ministry of Education launched a nationwide football-focused pilot project aimed at kindergartens in 2019 and issued the policy “Notice on the Establishment of National Football Kindergartens” in 2020. However, the impact of fundamental movement skills (FMS) interventions on other aspects of child development is unclear.

This study will evaluate the effects of ball skills physical education projects on the development of Chinese preschoolers’ physical, motor, cognitive, and social competencies and examine the influencing factors.

This is a quasi-experimental study evaluating how well the “Hello Sunshine” curriculum project promotes children’s development over 10 weeks. The trial will be conducted from September 2021 to November 2021 in 12 classes from 3 kindergartens with a total of 249 children aged 4 to 6 years in Haikou, China. Pre- and posttest analyses will include tests on participants’ physical fitness, FMS, cognitive self-regulation, and emotional competence. Participants’ background information will be collected through questionnaires answered by parents and teachers. The intervention will focus on game-based basic ball skills.

If this intervention provides evidence that these skills improve children’s multidimensional development, it will support the promotion of similar programs in China. We will also outline the social-ecological factors affecting the intervention’s results, providing further information for improving pedagogical methods related to preschool ball skills.

Studies examining the impact of adolescent and young adult cannabis use on structural outcomes have been heterogeneous. One already-identified moderator is sex, while a novel potential moderator is extent of aerobic fitness. Here, we sought to investigate the associations of cannabis use, sex, and aerobic fitness levels on brain volume. Second, we explored brain–behavior relationships to interpret these findings.

Seventy-four adolescents and young adults (36 cannabis users and 38 controls) underwent 3 weeks of monitored cannabis abstinence, aerobic fitness testing, structural neuroimaging, and neuropsychological testing. Linear regressions examined cannabis use and its interaction with sex and aerobic fitness on whole-brain cortical volume and subcortical regions of interests.

No main-effect differences between cannabis users and nonusers were observed; however, cannabis-by-sex interactions identified differences in frontal, temporal, and paracentral volumes. Female cannabis users generally exhibited greater volume while male users exhibited less volume compared to same-sex controls. Positive associations between aerobic fitness and frontal, parietal, cerebellum, and caudate volumes were observed. Cannabis-by-fitness interaction was linked with left superior temporal volume. Preliminary brain–behavior correlations revealed that abnormal volumes were not advantageous in either male or female cannabis users.

Aerobic fitness was linked with greater brain volume and sex moderated the effect of cannabis use on volume; preliminary brain–behavior correlations revealed that differences in cannabis users were not linked with advantageous cognitive performance. Implications of sex-specific subtleties and mechanisms of aerobic fitness require large-scale investigation. Furthermore, present findings and prior literature on aerobic exercise warrant examinations of aerobic fitness interventions that aimed at improving neurocognitive health in substance-using youth.

To explore the relationship between dietary patterns and physical fitness among older Chinese (≥60 years) individuals.

Cross-sectional survey. Dietary data were collected by a simplified semi-quantitative FFQ. The 30-s Chair Stand test (30sCST), 30-s Arm Curl test (30sACT), 8-foot Time Up-and-Go test (8fTUAGT) and 6-min Walking test (6mWT) were used to assess physical fitness. Dietary patterns were obtained by factor analysis. The association between dietary patterns and physical fitness was explored by multiple logistic regression.

Six communities (villages) of three districts in Liaocheng City (Shandong Province, China).

A total of 596 residents were recruited from April to May 2017.

Among 556 residents who were finally enrolled, 196 were men (35 %) and 360 were women (65 %). Three dietary patterns were identified: ‘Western’, ‘Vegetarian’ and ‘Modern’. The 30sACT revealed that men in the fourth quartile of the Western pattern were less likely to be classified in the ‘high-level’ group, but men in the fourth quartile of the Vegetarian pattern were classified in the high-level group. The 6mWT revealed that men in the fourth quartile of the Modern pattern were classified in the high-level group. These associations were independent of confounding factors.

Adherence to the Vegetarian pattern and Modern pattern may be protective factors for maintaining good physical fitness in older Chinese individuals. The Western pattern may lead to poor physical fitness in this population.

To investigate the reproducibility of the Eurofit physical fitness test battery in patients with schizophrenia or schizoaffective disorder. Secondary aims were to assess clinical and demographic characteristics that correlate with the performance on the Eurofit and evaluation of the feasibility of the test.

Fifty patients with schizophrenia or schizoaffective disorder (mean age of 32.9±9.5years) with a mean body mass index (BMI) of 26.1±6.0kg/m2 performed two Eurofit tests administered within 3days.

All Eurofit items showed good reproducibility with intraclass correlation coefficients ranging from 0.72 for flamingo balance to 0.98 for standing broad jump test. All participants could perform five of the seven test items without problems. The whole body balance and abdominal muscle endurance test could be executed by 74 and 90%, respectively. Significant correlations were found with age, BMI, waist circumference, dose of antipsychotic medication and extrapyramidal, negative and cognitive symptoms.

The Eurofit test showed good reproducibility and can be recommended for evaluating physical fitness parameters in patients with schizophrenia or schizoaffective disorder. Physical fitness measures were related to both physical and mental health parameters.

Birthweight (BW) has been associated with anthropometry, body composition and physical fitness during growth and development of children. However, less is known about the mediation effect of those variables on the relationship between BW and basal metabolic rate (BMR) in children.

To analyse the mediation effect of anthropometry, body composition and physical fitness on the association between BW and BMR in children.

In total, 499 children (254 boys, 245 girls) aged 7–10 years were included. Anthropometry (weight, height, head, waist and hip circumferences), body composition (skinfolds thickness, body fat percentage), physical fitness (handgrip strength, flexibility, muscular endurance, muscular explosive power, agility, running speed) and BMR were evaluated. The analyses were conducted by: single-mediator analysis (SMA) and multi-mediator analysis (MMA).

The SMA indicates height, head, waist and hip circumferences and handgrip strength as significant mediators of BW on BMR for boys and height, hip circumference and handgrip strength as significant mediators of BW on BMR for girls. In MMA for girls, there were significant indirect effects for height, hip circumference and handgrip strength, with 79.08% of percent mediation. For boys, the head and waist circumferences mediation had a significant indirect effect, with 83.37% of percent mediation.

The anthropometric variables associated with BW were body height, head, hip and waist circumferences for boys and body height and hip circumference for girls. The current study provides new evidence that height and handgrip strength during childhood mediated the relationship between BW and BMR.

Cardiovascular fitness influences many aspects of brain function. However, the relationship between cardiovascular fitness and suicidal behaviour is unknown. Therefore, we aimed to determine whether cardiovascular fitness at age 18 years is associated with future risk of suicide attempt/death.

We performed a population-based Swedish longitudinal cohort study of male conscripts with no previous or ongoing mental illness (n = 1 136 527). The conscription examination, which took place during 1968–2005, included the cycle ergonometric test and tests of cognitive performance. Future risk of suicide attempt/death over a 5- to 42-year follow-up period was calculated with Cox proportional hazards models controlling for several confounders including familial factors.

At least one suicide attempt was recorded for 12 563 men. Death by suicide without a prior attempt was recorded in 4814 additional individuals. In fully adjusted models low cardiovascular fitness was associated with increased risk for future attempt/death by suicide [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.64–1.94]. The HR changed only marginally after exclusion of persons who received in-patient care for depression (HR 1.76, 95% CI 1.61–1.94). Poor performance on both the cardiovascular fitness and cognitive tests was associated with a fivefold increased risk of suicide attempt or suicide death (HR 5.46, 95% CI 4.78–6.24).

Lower cardiovascular fitness at age 18 years was, after adjustment for a number of potential confounders, associated with an increased risk of attempt/death by suicide in adulthood. It remains to be clarified whether interventions designed to improve fitness in teens can influence the risk of suicidal behaviour later in life.
