RESUMO

Children with disability face many barriers to participating in community sports. Little Athletics Australia aims to increase fair and meaningful inclusion via a new structure which will enable all children to take part in the same contest by competing for their 'personal best' score. Named the True Inclusion Method (TIM), this new structure will be piloted in 13 sites across six states. Formative evaluation of this pilot will critique TIM and its implementation using observations of events, and interviews and surveys with child athletes with and without disability, their parents/carers and Little Athletics volunteers. Implementation outcomes are acceptability, appropriateness, adoption, feasibility and fidelity. Qualitative data will be analysed thematically. TIM is designed to encourage inclusive participation by children with disability in sporting events, and to improve the competitive experience for all children by celebrating personal achievement and fostering fun.

RESUMO

Social justice education (SJE) prepares clinicians to provide patient-centered care. Our purpose was to assess SJE in CAATE-accredited, post-baccalaureate professional athletic training programs. We used a cross-sectional, online survey. Individuals (n=215) in their last year of post-baccalaureate professional education or those who were within 6 months post-graduation participated. The survey included closed and open-ended questions regarding types of education, topics of education, perceived confidence, and levels of agreement regarding identifying, addressing, and applying social justice concepts. Students from different cultural ethnicities reported having different educational experiences relative to their formal and informal instruction. Significant differences were identified between cultural ethnicity groups on perceptions of professors' knowledge (p<0.001), preceptors' knowledge (p<0.001), and agreement their program prepared them to address social justice issues (p<0.001). Two domains emerged from the open-ended responses: 1) social justice defined and 2) educational needs. Participants described social justice as equality, equity, and justice for minoritized people. Participants described SJE as not occurring or limited, and they expressed a desire for active practical experiences from heterogeneous and unbiased sources. As programs move to incorporate CAATE standards, more frequent and varied SJE is expected from minoritized students.

RESUMO

HEALTH CARE ORGANIZATION FOR 2024 OLYMPICS AND PARALYMPICS GAMES. The 2024 olympic and paralympic Games (JOP 2024) constitute the largest global festive event. While this major international gathering is primarily synonymous with celebrations, health security represents a major challenge for the French healthcare system in a highly tense national and international context. The health security of the JOP 2024 relies on close collaboration between the medical service of the organizer Paris 2024, responsible for care at the Olympic sites, and state services (SAMU, Law Enforcement, Firefighters) providing support in the event of serious health incidents or exceptional health situations (SSE). The projected impact on our healthcare structures (excluding SSE) appears moderate, as a 5% increase in hospital activity and approximately 150 additional daily emergencies are expected during the Olympic period compared to a normal summer season. In the event of a major incident resulting in a large number of casualties, state services will take over the governance of relief efforts by activating the ORSEC-NOVI and ORSAN-AMAVI plans for health response. The preparation of this health coverage involves an unprecedented mobilization of all healthcare stakeholders and is manifested by the organization of exercises at a very brisk pace.


ORGANISATION DU SYSTÈME DE SOINS POUR LES JEUX OLYMPIQUES ET PARALYMPIQUES 2024. Les Jeux olympiques et paralympiques 2024 (JOP 2024) constituent le plus important événement festif mondial. Si ce grand rassemblement international se veut avant tout synonyme de fête, la sécurité sanitaire représente un enjeu majeur pour le système de soins français, dans un contexte national et international en tension majeure. La sécurité sanitaire des JOP 2024 relève d'une étroite collaboration entre le service médical de l'organisateur Paris 2024, responsable des soins sur les sites olympiques, et les services de l'État (Samu, forces de l'ordre, sapeurs-pompiers) venant en soutien en cas d'événements sanitaires graves ou en cas de situation sanitaire exceptionnelle. La prévision de l'impact sur les structures sanitaires (en dehors de situation sanitaire exceptionnelle) semble modérée, puisque l'on attend une augmentation de 5 % de l'activité hospitalière et environ 150 urgences journalières de plus pendant la période olympique par rapport à une saison estivale normale. En cas d'événement majeur générant un grand nombre de victimes, les services de l'État prendront la gouvernance des secours par le déclenchement des plans ORSECNOVI et ORSAN-AMAVI pour la valence sanitaire. La préparation de cette couverture sanitaire fait appel à une mobilisation sans précédent de tous les acteurs de santé et se concrétise par l'organisation d'exercices à un r ythme très soutenu.

RESUMO

Background: Less than one-quarter of US children meet physical activity (PA) guidelines. Understanding the context in which PA occurs and how these contexts may play a role in meeting PA guidelines is an essential step toward developing effective behavioral interventions. The purpose of this study was to examine associations between PA context (sports participation, participation in other organized physical activities, active travel to school, and outdoor play) and the number of days children met PA guidelines in a representative sample of children living in Texas. Methods: We analyzed cross-sectional data from a statewide sample of fourth-grade children in Texas who completed the 2019-2020 Texas School Physical Activity and Nutrition (Texas SPAN) survey. The Texas SPAN survey was designed to monitor the statewide prevalence of overweight/obesity among school children and assess habitual self-reported obesity-related behaviors, including diet and PA. Weighted Poisson regression models were employed to examine the associations between PA contexts (sports participation, participation in other organized physical activities, active travel to school, and outdoor play) and the number of days children met PA guidelines, adjusting for sex, race/ethnicity, overweight/obesity, urban-rural status, and economic disadvantage. Results: A total of 16.7% of fourth-grade children met physical activity guidelines every day during the week (mean age = 9.4 ± 0.6 years; female = 48.7, 51.8% Hispanic, mean days meeting PA guideline = 3.6 ± 2.3 days). One in ten (11.2%) children did not meet daily PA guidelines on any day of the week, and 72.1% met them between 1 and 6 days. Participating in sports (b = 0.22, 95%CI:0.14, 0.30), any other organized physical activities (b=0.13, 95%CI:0.017, 0.19), and playing outdoors 1-3 days (b = 0.25, 95%CI:0.04, 0.46) and 4-7 days in the past week (b = 0.77, 95%CI:0.57, 0.97) was significantly and positively associated with the number of days children met PA guidelines. Conclusion: Participating in sports, participating in other organized physical activities, and playing outdoors may beneficially influence the number of days children meet PA guidelines. PA programs should consider these contextual factors and investigate how to promote organized activities and outdoor play effectively and appropriately among children.

RESUMO

BACKGROUND AND RESEARCH OBJECTIVES: Given the enduring popularity of higher education, there has been considerable attention on the correlation between college students' engagement in sports and their academic stress levels. This study seeks to delve deeply into how university physical education fosters academic performance by influencing students' sports interests, particularly in enhancing their psychological resilience to mitigate academic pressure. Through this investigation, the aim is to offer both theoretical underpinnings and empirical evidence to support the holistic enhancement of higher education. RESEARCH METHODS: Initially, this study undertakes an analysis of the fundamental relationship between college students' physical activities and their experience of academic stress. Subsequently, utilizing a structural equation model, specific research models and hypotheses are formulated. These are then examined in detail through the questionnaire method to elucidate the mechanism by which college sports interests alleviate academic stress. RESEARCH FINDINGS: The study reveals a significant positive correlation between psychological resilience and academic stress, indicating that a robust psychological resilience can effectively diminish academic pressure. Furthermore, both the sports atmosphere and sports interest are found to exert a notable positive impact on academic stress, mediated by the variable of psychological toughness. This underscores the pivotal role of physical education in fostering positive psychological traits and enhancing academic achievement. CONCLUSION: This study underscores the central importance of cultivating and nurturing college students' sports interests, as well as fostering a conducive sports atmosphere, in fortifying psychological resilience and mitigating academic pressure. By offering novel perspectives and strategies for alleviating the academic stress faced by college students, this study contributes valuable theoretical insights and practical experiences to the broader development of higher education.

RESUMO

The present study aimed to identify the impact of various periodisation approaches used in training athletes and to identify the effect size of the periodisation technique in improving athletes' peak performance before the main event. Inclusion criteria comprised recruitment of all those studies in which the effects of periodisation training were identified on athletes' peak performance. Various databases such as Google Scholar, Pedro, MEDLINE, Cochrane Library, EMBASE, and Web of Science were searched by independent reviewers using the MeSH terms including 'interval training', 'aerobic exercise', 'periodisation,' 'peak performance', and 'athletes'. A sample size of n = 121 participants included in six studies were analysed in which the effects of periodisation methods of training among athletes were estimated for improving their peak performance by assessing jump height and speed, pool effects in the form of random, and fixed effect model were provided to depict cumulative results of all the included studies. In achieving optimisation in athletes' peak performance, inculcating the concept of periodisation is a practical approach. While incorporating periodisation in training, models of training principles must be given ardent importance. Key Words: Exercise training, Sports, Athletes, Periodisation, Peak performance.

RESUMO

INTRODUCTION: Mouthguards (MGs) have the potential to prevent contact sport-related dental injuries. However, varying perceptions of their effectiveness persist, influencing recommendations by dental professionals. AIM: To assess the attitudes, knowledge, and perceptions of orthodontists, other dental practitioners (general dentists and other dental specialists), and orthodontic patients involved in contact sports regarding the use of MGs. METHODOLOGY: A cross-sectional survey was designed to collect information from dental clinicians (orthodontists and other dental practitioners) and their orthodontic patients about using MGs during sports participation. A convenience sampling technique was used to recruit the participants for an online survey. A total of 107 (32 males/75 females) dental clinicians and 147 (75 males/72 females) orthodontic patients (mean age 17.5 ± 5.84 years) participated in the study. Pre-validated questionnaires, specifically designed for dental clinicians and orthodontic patients, were used. Data were analyzed using SPSS software (version 28.0; SPSS). RESULTS: Nearly 50% of dental clinicians have recently recommended MGs to their patients in their clinical practice out of which 59% preferred the stock type; 33% of dental clinicians enquired their patients about involvement in contact sports during initial visits. The majority of orthodontic patients acquired knowledge about MGs through the Internet. More than half of orthodontic patients expressed unwillingness to pay for MGs, and 89% of orthodontic patients found using MGs during contact sports uncomfortable. CONCLUSION: The findings provide valuable insights into the practices and attitudes of dental clinicians and orthodontic patients regarding MGs, their recommendations, and the comfort levels associated with using them during contact sports.

RESUMO

The aim of this study is to analyse the relationship between sport modalities practiced, physical fitness, body composition, and healthy habits in an active young population, using a statistical model for prediction. A total of 2255 (1528 boys and 727 girls) children and adolescents aged 6-17 years old who were involved in extracurricular sports from rural areas of Spain participated. Physical fitness was assessed through validated field test and, body composition was determinated using bioelectrical impedance analysis. Adherence to the Mediterranean diet was assessed by KIDMED questionnaire. The general sport variable was significant in VO2max when comparing the invasion and combat modalities to the reference level (court/net). The sex and age variables revealed significant differences in all physical fitness and body composition parameters. Health parameters, such as hours of additional practice, adherence to the Mediterranean diet, and previous experience, showed significant differences. The study concludes that the sport modality variables of training, sex, age, and maturational period have an impact on body composition and fitness parameters in this population. Therefore, by focusing on factors associated with lower values in health indicators, we can prevent health problems during adulthood, such as cardiorespiratory deficits.

RESUMO

OBJECTIVE: To describe the current distribution of daily physical activity time among elementary and junior high school students in Beijing, and to analyze the influencing factors and pathways at the individual, family, school and community levels. METHODS: Data were drawn upon from a cross-sectional investigation in Beijing in 2023, and a total of 3 157 elementary and junior high school students were included in the final analysis. Questionnaire was used to collect data on basic characteristics, overall and in-school physical activity time per day, the number of sports mastered, perceived physical activity benefits and barriers scales, perceived family, school, and community physical activity supportive environment scales. Log-binomial regression model was used to analyze the associations between physical activity time and influencing factors, and structural equation modeling was used for the path analysis of the influencing factors. RESULTS: The reported rates of ≥2 hours of overall physical activity per day and ≥1 hour of physical activity in school per day among elementary and junior high school students in Beijing in 2023 were 33.1% and 64.8%, respectively. The associations between the number of sports mastered by students and the reported rate of ≥2 hours of overall physical activity per day showed a typical dose-response relationship (P-trend<0.001). The perceived physical activity benefits-to-barriers ratio (PR=1.24, 95%CI: 1.20-1.28), scores of perceived family, school, and community physical acti-vity supportive environment scales were all positively associated with the reported rate of ≥2 hours of overall physical activity per day (PR=1.51, 95%CI: 1.38-1.66; PR=1.50, 95%CI: 1.37-1.64; PR=1.21, 95%CI: 1.16-1.27). The structural equation modeling showed that the number of sports mastered by the students (ß=0.11, P<0.001), perceived physical activity benefits-to-barriers ratios (ß=0.15, P<0.001), and scores of supportive environment scales consisting of family, school, and community (ß=0.13, P<0.001) were associated with the reported rates of ≥2 hours of overall physical activity per day directly. In addition, the scores of supportive environment scales could indirectly influence the reported rates of ≥2 hours of overall physical activity per day by influencing the number of sports mastered by the students (ß=0.21, P<0.001) and the perceived physical activity benefits-to-barriers ratio (ß=0.56, P<0.001), while the number of sports mastered by the students could indirectly influence the reported rates of ≥2 hours of overall physical activity per day by influencing the perceived physical activity benefits-to-barriers ratios (ß=0.05, P=0.003). The influencing factors and pathways of the reported rates of ≥1 hour of physical activity in school per day were similar with those of the reported rates of ≥2 hours of overall physical activity per day described above. CONCLUSION: The daily physical activity time among elementary and junior high school students in Beijing in 2023 fell short of meeting the national requirement. There was a need to build a supportive environment consisting of family, school, and community for physical activity, to promote the students ' sports skills, to establish the idea of independent physical activity, and to ensure that primary and secondary school students were given one hour of physical activity time every day, both inside and outside the school.

RESUMO

OBJECTIVES: The aim of the present study was to analyze the association between sports participation in childhood and adolescence and the practice of physical activity at different intensities in adulthood, and to verify if some sports participation characteristics such as number of sports; type of sport (individual, collective or a combination of both) and total estimated sports participation time are associated with the different physical activity intensities in adulthood. DESIGN: This is a cross-sectional study. METHODS: This study included 129 young adults of both sexes aged 18-25 years. Sports participation in childhood (7-10 years) and adolescence (11-17 years) was retrospectively estimated through specific questionnaire. Light, moderate, vigorous and moderate to vigorous intensity physical activity was objectively estimated by accelerometers. To verify the association between SP in childhood and adolescence and BP intensities in adults, multiple linear regression was adopted, with 5% significance. RESULTS: Analyses showed that, in females, sports participation in childhood (ß = 0.315; R2 = 0.14; P = 0.020) and persistence in sports participation (ß = 0.364; R2 = 0.18; P = 0.007) were positive predictors of vigorous physical activity in adulthood. In addition, the comparison according to the specificities of the sport practice, indicated that participation in two or more sports in childhood, one sport and collective sports in adolescence and at least one year of sports participation throughout childhood and adolescence were associated with longer time in vigorous physical activity intensity and MVPA (minutes/day) in adult females (P < 0.05). CONCLUSIONS: It could be concluded that sports participation indicators in childhood and adolescence were considered predictors of vigorous physical activity in adult females. In addition, number of sports, type of sport and practice time in childhood and adolescence seem to predict vigorous and moderate to vigorous levels of physical activity for adult females.

RESUMO

BACKGROUND: The aim of the study was to assess factors affecting the popliteal angle and foot dorsiflexion, in particular gender. The subjects were 142 students from the 2nd and 3rd year of Poznan junior high schools. METHODS: The participants included 57 girls and 87 boys. Three raters examined each subject: a specialist in orthopaedics, a resident doctor and a physical therapy student. Foot dorsal flexion was tested in a supine position with lower limbs extended. Next, dorsal flexion was evaluated with the knee and hip in 90 degrees of flexion. Finally, a passive knee extension (PKE) test was carried out. The significance of the PKE test is that the lower the angle the more flexible the hamstrings. This is because the PKE measurement is the distance to the right angle, that is a full knee extension with the hip flexed. RESULTS: The non-parametric test (Mann-Whitney) and the Student's t-test showed differences between the female and male gender in the measurements of the popliteal angle (p < .05000). The correlation was negative, which means that the hamstrings are more flexible in girls. No differences were found between gender and passive foot dorsiflexion and dorsiflexion with a flexed hip and knee. No differences were found between the group with the extended PE curriculum and the group with the standard number of PE classes in the range of motion of foot dorsiflexion and the value of the popliteal angle. CONCLUSIONS: Girls between 13 and 15 years old have a significantly larger hamstring flexibility, which is confirmed by the tests of the popliteal angle. No differences were found in dorsiflexion between girls and boys who have not been trained using a training model.

RESUMO

Association between genomic variants and athletic performance has seen a high degree of controversy, as there is often conflicting data as far as the association of genomic variants with endurance, speed and strength is concerned. Here, findings from a thorough meta-analysis from 4228 articles exploring the association of genomic variants with athletic performance in power and endurance sports are summarized, aiming to confirm or overrule the association of genetic variants with athletic performance of all types. From the 4228 articles, only 107 were eligible for further analysis, including 37 different genes. From these, there were 21 articles for the ACE gene, 29 articles for the ACTN3 gene and 8 articles for both the ACE and ACTN3 genes, including 54,382 subjects in total, from which 11,501 were endurance and power athletes and 42,881 control subjects. These data show that there is no statistically significant association between genomic variants and athletic performance either for endurance or power sports, underlying the fact that it is highly risky and even unethical to make such genetic testing services for athletic performance available to the general public. Overall, a strict regulatory monitoring should be exercised by health and other legislative authorities to protect the public from such services from an emerging discipline that still lacks the necessary scientific evidence and subsequent regulatory approval.

RESUMO

OBJECTIVE: To investigate the association between components of physical activity and spatiotemporal gait parameters in community-dwelling older adults. METHODS: Cross-sectional study with 134 independent community-dwelling older adults. A questionnaire was applied to obtain information related to the components of physical activity (frequency, duration, modality, and history of physical activity in the life course) and the GAITRite System was used to quantify gait parameters. Three MANOVA models adjusted for potential confounders were conducted to identify associations between components of physical activity (predictors) and gait performance (outcome). RESULTS: Higher weekly frequency but not daily hours of physical activity and sports practice (tennis, boxing, football, volleyball, and tai chi) were significantly associated with better gait performance, specifically gait speed and stride length. CONCLUSION: Understanding the most effective components of physical activity to maintain functional capacity and independence in community-dwelling older adults, allowing for active aging, is essential for formulating more effective strategies.

RESUMO

This study employed Rasch analyses to validate a novel measure of sport experience: the Sport Experience Measure: Children and Youth (SEM:CY). Analyses were applied to self-reported data of n = 503 young people (age 9-18 years, M = 12.91, 50% female) in Canada who were engaging in sport during the previous 12 months. The revised measure, consisting of 24 items on a 3-point response scale, demonstrated good fit statistics (e.g., item fit residual: M = -0.50, SD = 0.94 and person fit residual: M = -0.62, SD = 2.33), an ability to reliably discriminate between levels of sport experience, and an absence of differential item functioning for various groups (males and females, older and younger individuals, solo and team sports, and those playing at various competitive levels, including recreation). The SEM:CY is a succinct tool that can serve as a valuable means to gauge the quality of an individual's sport experience, which can facilitate positive youth development and sustain participation across the life span.

RESUMO

Professional athletes competing in the NBA are frequently exposed to time-zone-shifting travels. These time zone changes may cause circadian rhythm (CR) phase shifts and these shifts affect sportive performance. The aim of this study was to investigate the effects of CR phase shifts on the performance of NBA teams. 25016 regular season games across 21 consecutive seasons were included in the CR phase shift calculations. To examine the CR phase shift effect on team performance, teams were divided into three groups regarding Coordinated Universal Time (UTC): the same internal UTC as the local UTC (LS); the internal UTC ahead of the local UTC (LA); and the internal UTC behind the local UTC (LB). With a different approach, teams were divided into another three categories: the same internal UTC as its opponent's internal UTC (OS); the internal UTC ahead of its opponent's internal UTC (OA); and the internal UTC behind its opponent's internal UTC (OB). 24985 game data were used to compare these groups in terms of 25 variables. Statistical analyses were conducted separately for home and away teams. For home games, it was found that LA and OA are the most and LB is the least successful group in winning and scoring performances. For away games, it was determined that LS is the most advantageous group with the best winning percentage. These results revealed that teams from more west may have a CR advantage in regular season home games. However, it is thought that the performance of away teams depends more on travel fatigue than CR phase shifts.

RESUMO

OBJECTIVE: Aim: Dynamic comparison of the lower limbs length, depending on the type of sport, followed by the construction of a mathematical model for predicting sports abilities. PATIENTS AND METHODS: Materials and Methods: The comparison of the lower limbs length in dynamics was carried out on 132 students of higher education institutions of Bukovyna. While the primary study was carried out during September-October 2021, next study of these same students was conducted in September-October 2022. The main group consists of 92 (69.7%) students, the control group - 40 (30.30%) students aged 16 to 18 years. All students underwent an anthropometric study (determination of the length of the lower limbs) according to the method of P.P. Shaparenka. The comparesment of anthropometric parameters in the main group depending on the type of sport used the Kruskel-Wallis test (non-parametric analysis of variance) in order to identify a reliable difference in the average indicators of the respondents depending on the type of sport (the median of the distribution was considered as a measure of central tendency). In order to establish which pairs of age groups had a statistical difference in the medians, the Conover-Iman test was used. A paired t-test (t-test of paired samples) was performed to compare the length of the respondents' lower limbs during the first measurement and again one year later. Statistical analysis of the obtained data was performed using the licensed RStudio program. RESULTS: Results: The distribution of the length of the right lower limb of the respondents of the main group by measurement shows that the average value of the length of the right lower limb has changed: a significant difference in the length of the right lower limb was found between the first (M = 88.812, SD = 5.287) and the second (M = 89.377, SD = 5.347) measurements; t (68) = -5.223, p < 0.001. The distribution of the length of the left lower limb shows that the average value of the length of the left lower limb has changed also: a significant difference in the length of the left lower limb was found between the first (M = 88.667, SD = 5.266) and the second (M = 89.435, SD = 5.309) measurements; t (68) = -8.289, p < 0.001. CONCLUSION: Conclusions: In order to dynamically compare the length of the lower limbs for comprehensive control and selection of promising students in football, volleyball, handball and basketball, a mathematical model was derived for predicting the length of the lower limbs, in corresponding sports: right lower limb y = 0.506 x and left y = 0.507x, where y - is the length of the left lower limb, x - is the height. The coefficient of determination is 99.8%. A significant predictor for the length of both lower limbs is the height.
