Sport mental health continuum in young Brazilian athletes: adaptation and psychometric properties.

Instruments used to assess the mental well-being of young athletes in Brazil are scarce. Therefore, the present study aimed to translate, cross-culturally adapt for young athletes, and gather evidence of validity for the Sport Mental Health-Short Form (S-MHC) for use in Brazilian Portuguese. The research was conducted in five stages: translation, synthesis, back-translation, expert review, and validation of the psychometric properties. For validation, 246 young athletes of both genders (88 females, 35.8%), aged between 12 and 18 years (14.5 ± 1.9 years), were recruited. Psychometric methods were employed to confirm and validate the translated and adapted versions of the S-MHC for young athletes, including internal consistency using Cronbach's alpha and McDonald's omega, composite reliability, Item Characteristic Curve (ICC) using Item Response Theory (IRT), and Confirmatory Factor Analysis (CFA). Two structures were tested, with Model 1 loading the 14 items of the translated version of the S-MHC into a single latent factor and Model 2 loading the items into three factors related to emotional, social, and psychological sport well-being. Both models showed good validity, consistency, and reliability measures and can be used to investigate the sport well-being of young athletes. It was concluded that the translated version of the S-MHC in Brazilian Portuguese can be used to assess the sport well-being of young athletes in Brazil. Model 2 structure is recommended to observe the different nuances of emotional, social, and psychological well-being.

Analysis of the association between different domains and intensities of physical activity in adults: An observational and cross-sectional study.

BACKGROUND AND OBJECTIVE: To analyze the association between different domains and intensities of physical activity (PA) in adults. METHODS: 269 participants were randomly selected in a community-dwelling representative sampling process. The habitual PA practice was assessed in different domains (occupational, sports practice, and leisure time/commuting) using Baecke's questionnaire and in different intensities (light, moderate, vigorous, and very vigorous) by accelerometry. Linear regression models analyzed the association between variables. RESULTS: Moderate and moderate-to-vigorous PA was positively associated with the three PA domain scores. Vigorous PA was associated with sports practice and leisure time/commuting PA. Only sports practice was associated with very vigorous-intensity PA (ß = 1.32; 95% CI = 0.29; 2.35). Different associations were observed in stratified analyses according to sex and age groups. Men and younger participants showed an association of domain scores with higher intensity PA than their counterparts. CONCLUSION: The findings suggest that higher intensities of PA were observed primarily in leisure time/commuting PA and sports practice, and this association varied according to sex and age.

Spatial distribution of the sport fishing in the state of Amazonas, northern Brazil.

The objective of this study was to spatialize sport fishing operations and assess the frequency of the use of the fishing areas in the state of Amazonas by combining the Geographic Information System (GIS) approach and information available in the documents sent to the Instituto de Proteção Ambiental do Amazonas (IPAAM). Information on sport fishing tourism operations was gathered from the IPAAM database and fishing licenses (FLs). Data analysis was conducted utilizing descriptive analysis, and the spatialization of the locations was performed using Q-GIS software. From 2002 to August 2021, 163 requests for FLs were made. There was a decrease in the amount of first time FL requests, with a peak in 2018 and 2019, N=17 and N=18, respectively. The activity is conducted in 24 municipalities, with Barcelos (31.36%) and Presidente Figueiredo (17.75%) being the most popular. At the sub-basin level, sport fishing is notably present in the Negro, Amazonas, Aripuanã, Madeira, Purus and Solimões River basins. Overall, 26.38% of operations take place in conservation areas, specifically in sustainable development reserves (SDRs). Barcelos recorded the largest number of rivers used, with 15 rivers. These results can support future proposals for the sustainable management of fisheries through the zoning of fishing areas in the state of Amazonas.

Exposing illegal hunting and wildlife depletion in the world's largest tropical country through social media data.

Globally, illegal sport hunting can threaten prey populations when unregulated. Due to its covert nature, illegal sport hunting poses challenges for data collection, hindering efforts to understand the full extent of its impacts. We gathered social media data to analyze patterns of illegal sport hunting and wildlife depletion across Brazil. We collected data for 2 years (2018-2020) across 5 Facebook groups containing posts depicting pictures of illegal sport hunting events of native fauna. We described and mapped these hunting events by detailing the number of hunters involved, the number of species, the mean body mass of individuals, and the number and biomass of individuals hunted per unit area, stratified by Brazilian biome. We also examined the effects of defaunation on hunting yield and composition via regression models, rank-abundance curves, and spatial interpolation. We detected 2046 illegal sport hunting posts portraying the hunting of 4658 animals (∼29 t of undressed meat) across all 27 states and 6 natural biomes of Brazil. Of 157 native species targeted by hunters, 19 are currently threatened with extinction. We estimated that 1414 hunters extracted 3251 kg/million km2. Some areas exhibited more pronounced wildlife depletion, in particular the Atlantic Forest and Caatinga biomes. In these areas, there was a shift from large mammals and reptiles to small birds as the main targeted taxa, and biomass extracted per hunting event and mean body mass across all taxonomic groups were lower than in other areas. Our results highlight that illegal sport hunting adds to the pressures of subsistence hunting and the wild meat trade on Brazil's wildlife populations. Enhanced surveillance efforts are needed to reduce illegal sport hunting levels and to develop well-managed sustainable sport hunting programs. These can support wildlife conservation and offer incentives for local communities to oversee designated sport hunting areas.

Exposición de la caza ilegal y la reducción de fauna en el país tropical más grande del mundo por medio de datos de las redes sociales Resumen En todo el mundo, la caza recreativa ilegal puede amenazar a las poblaciones de presas cuando no está regulada. Debido a su naturaleza encubierta, la caza recreativa ilegal plantea dificultades para la recopilación de datos, lo que dificulta la comprensión de su impacto. Recopilamos datos de redes sociales para analizar los patrones de caza recreativa ilegal y agotamiento de la vida silvestre en todo Brasil. Recopilamos datos durante 2 años (2018­2020) a través de cinco grupos de Facebook que contenían publicaciones que mostraban imágenes de eventos de caza recreativa ilegal de fauna nativa. Describimos y mapeamos estos eventos de caza detallando el número de cazadores involucrados, el número de especies, la masa corporal media de los individuos y el número y la biomasa de los individuos cazados por unidad de área, estratificados por bioma brasileño. También examinamos los efectos de la deforestación en el rendimiento y la composición de la caza mediante modelos de regresión, curvas de abundancia e interpolación espacial. Detectamos 2,046 puestos de caza recreativa ilegal que mostraban la caza de 4,658 animales (∼29 t de carne sin desollar) en los 27 estados y 6 biomas naturales de Brasil. De las 157 especies autóctonas objetivo de los cazadores, 18 están actualmente en peligro de extinción. Se calcula que 1,414 cazadores extrajeron 3,251 kg/millón de km2. Algunas zonas mostraron una defaunación más pronunciada, en particular los biomas de la Mata Atlántica y la Caatinga. En estas áreas, se produjo un cambio de grandes mamíferos y reptiles a pequeñas aves como principales taxones objetivo, y la biomasa extraída por evento de caza y la masa corporal media en todos los grupos taxonómicos fueron menores que en otras áreas. Nuestros resultados ponen de manifiesto que la caza recreativa ilegal se suma a las presiones de la caza de subsistencia y el comercio de carne salvaje sobre las poblaciones de fauna de Brasil. Es necesario intensificar los esfuerzos de vigilancia para reducir los niveles de caza recreativa ilegal y desarrollar programas de caza recreativa sostenibles y bien gestionados. Estos programas pueden contribuir a la conservación de la fauna y ofrecer incentivos a las comunidades locales para que supervisen las zonas designadas para la caza recreativa.

Caffeine Placebo Effect in Sport and Exercise: A Systematic Review.

The objective of this review article is to systematically identify the caffeine placebo effect in sport and exercise activities. We selected randomized controlled trial studies to better understand the impact of caffeine and its placebo effect on sports performance. We extracted a set of articles that refer strictly to the topics of caffeine and its placebo effect in sport and exercise, considering the databases integrated to the Core Collection Web of Science and Scopus, as well as the registration of the documents in PubMed®, a system with a selection process aligned with the guidelines for the PRISMA methodology, establishing the eligibility criteria of the articles with the PICOS tool, to which a systematic review is applied. Finally, the results show that caffeine improves anaerobic capacity and endurance, while placebo perceived as caffeine can also increase performance by reducing pain and improving concentration. This finding underscores the influence of expectations and placebo on physical performance, suggesting that managing these expectations may be an effective strategy for improving athletic performance.

Global hotspots and trends of nutritional supplements in sport and exercise from 2000 to 2024: a bibliometric analysis.

BACKGROUND: Nutritional supplements for sports and exercise (NSSE) can facilitate the exogenous replenishment of the body. This study provides the first extensive overview of NSSE research through bibliometric and visual analyses. METHODS: We searched the Web of Science Core Collection database for literature related to "NSSE" from 1st January 2000 to 8th March 2024. A total of 1744 articles were included. CiteSpace, VOSviewer, and Bibliometrix R package software were used to analyze the data. RESULTS: Research in the NSSE can be divided into steady growth, exponential growth, fluctuating stage, and surge stages. The United States is the most active country in this field. In recent years, the leading countries have been Croatia, Colombia, Slovenia, Chile, Egypt, China, and Thailand. The Australian Institute of Sports is the top research institution in terms of number of publications. Burke, LM from Australia published the most articles. Research in this area has primarily been published in Nutrients in Switzerland. The study population mainly consisted of men, and postmenopausal women were the main focus of the female group. Coronary heart and cardiovascular diseases continue to dominate research. CONCLUSION: Research on the NSSE is developing rapidly, with an annual growth trend. Insulin resistance, sports nutrition, inflammation, alpha-linolenic acid, limb strength performance, female sex, and gut microbiota are the focus of the current research and trends for future research. Future research should focus on improving the scientific training system for athletes and quality of training and life for the general public.

Effect of fatigue on knee biomechanics during the sidestep cutting manoeuvre: A modelling approach.

Loading both lateral and medial compartments is crucial to understanding the effect of muscle fatigue during sidestep cutting. The present study investigated the changes in tibiofemoral contact forces in the medial and lateral compartments and the muscle force contributions during the sidestep-cutting manoeuvre after a handball-specific fatigue protocol. Twenty female handball athletes performed three trials of the sidestep-cutting manoeuvre before (baseline) and after the fatigue protocol. Motion capture and ground reaction forces were measured, and the data were processed in OpenSim. The variables were compared using statistical parametric mapping (SPM), with a significance level of p < 0.05. The results showed a decreased knee flexion angle during fatigue in the early stance phase. In addition, the post-fatigue analysis demonstrated significantly reduced forces in vasti muscles. Similarly, during fatigue, the SPM analysis showed decreased tibiofemoral contact forces in the vertical and anterior directions. Vertical force applied to both medial and lateral condyles demonstrated a significant reduction after the fatigue protocol. These results indicated that forces applied to the tibiofemoral joint were reduced following the fatigue protocol compared to the baseline values. However, no consistent evidence exists that fatigue increases the risk of knee injuries.

Psycho-physio-neurological correlates of qualitative attention, emotion and flow experiences in a close-to-real-life extreme sports situation: low- and high-altitude slackline walking.

It has been indicated that extreme sport activities result in a highly rewarding experience, despite also providing fear, stress and anxiety. Studies have related this experience to the concept of flow, a positive feeling that individuals undergo when they are completely immersed in an activity. However, little is known about the exact nature of these experiences, and, there are still no empirical results to characterize the brain dynamics during extreme sport practice. This work aimed at investigating changes in psychological responses while recording physiological (heart rate-HR, and breathing rate-BR) and neural (electroencephalographic-EEG) data of eight volunteers, during outdoors slackline walking in a mountainous environment at two different altitude conditions (1 m-low-walk- and 45 m-high-walk-from the ground). Low-walk showed a higher score on flow scale, while high-walk displayed a higher score in the negative affect aspects, which together point to some level of flow restriction during high-walk. The order of task performance was shown to be relevant for the physiological and neural variables. The brain behavior during flow, mainly considering attention networks, displayed the stimulus-driven ventral attention network-VAN, regionally prevailing (mainly at the frontal lobe), over the goal-directed dorsal attention network-DAN. Therefore, we suggest an interpretation of flow experiences as an opened attention to more changing details in the surroundings, i.e., configured as a 'task-constantly-opened-to-subtle-information experience', rather than a 'task-focused experience'.

Resumen Propósito: El presente estudio tiene como objetivo explorar la bibliografía existente sobre las habilidades y movimientos visuales en jugadores de tenis. Metodología: Se indagó en las bases de datos Scopus, SPORTDiscus, PubMed y Google Scholar que permn seleccionar 37 estudios empíricos realizados con un método cuantitativo. La elección de los estudios respondió a los criterios establecidos en torno a las palabras clave, temática del estudio y la metodología de investigación. Resultados: Los resultados se organizan en tres tópicos centrales: (a) Antecedentes de habilidades visuales en el siglo XX, (b) Siglo XXI: rol de los movimientos sacádicos y (c) Reflexiones sobre la gesta tenística y los movimientos sacádicos. Conclusiones: A lo largo de varias décadas de investigación y seguimiento al enfoque ''visión y deporte'' en el tenis de campo, específicamente en los movimientos visuales entre fijaciones y movimientos sacádicos, se pueden identificar niveles diferenciales de rendimiento tenístico con el potencial de ser indicadores de mejores desempeños deportivos. Dado que las herramientas utilizadas hasta ahora en esta disciplina para los procesos de selección o evaluación no son determinantes, debido a ser una disciplina deportiva multifactorial de orden perceptivo-motor y de habilidades abiertas, se sugiere que las habilidades visuales pueden ser indispensables para la adquisición de un alto nivel competitivo. Este aspecto plantea una línea de investigación interesante que merece una mayor exploración en el futuro.

Abstract: Purpose: The presente study aims to explore the existing bibliography on visual skills and visual movements in tennis players. Method: We searched the Scopus, SPORTDiscus, PubMed and Google Scholar databases, which allowed us to select 37 empirical studies carried out with a quantitative method. The choice of the studies responded to the criteria established around the Keywords, the subject of the study and the research methodology. Results: The results are organized into three central topics: (a) Antecedents of visual skills in the 20th century, (b) 21st century: Role of saccadic movements, and (c) Reflections on the tennis feat and saccadic movements. Conclusions: Throughout several decades of research and monitoring of the ''vision and sport'' approach in field tennis, specifically in the visual movements between fixations and saccadic movements, differential levels of tennis performance can be identified with the potential to be indicators of better sports performance. Given that the tools used so far in this discipline for the selection and/or evaluation processes are not determinant, due to being a multifactorial sport discipline of perceptual-motor order and open skills, it is suggested that visual skills may be essential for the acquisition of a high competitive level. This aspect raises an interesting line of research that deserves further exploration in the future.

Considerado patrimônio natural, o litoral piauiense é referência nacional e internacional para o Kitesurf, esporte na natureza pouco estudado, embora conste em pesquisas sobre desenvolvimento turístico na região. Este artigo analisa implicações da prática do Kitesurf nesse litoral e identifica ações que podem contribuir para sua conservação. Realizou-se pesquisa qualitativa, exploratória, mediante pesquisa bibliográfica e documental. Em certas praias há conflitos entre kitesurfista, pescador e/ou banhista; além da prática oferecer riscos para animais silvestres. Todavia, há kitesurfista que recolhe lixo no mar e promove discussões sobre efeitos do esporte na região. Abordar a educação ambiental em clínicas de certificação de kitesurfistas e regulamentar o Kitesurf pode colaborar com a resolução de conflitos e perspectivar um turismo mais sustentável, almejando conservar esse patrimônio e suas potencialidades.

The coast of Piauí, considered a natural heritage, is a national and international reference for kitesurfing, sport in naturelittle studied, although it is part of research on the regional tourism development. This article analyzes the implications of the practice of kitesurfing on this coast and identifies actions that can contribute to its conservation. Qualitative, exploratory research was carried out through bibliographical and documentary research. On certain beaches there are conflicts between kitesurfers, fishermen and/ or bathers; in addition, its practice offers risks to wild animals. However, there are kitesurfers who collects garbage at sea and promotes discussions about the effects of the sport in the region. Addressing environmental education of kitesurfers in certification clinics and regulating kitesurfing can collaborate with conflict resolution and envisage a more sustainable tourism, aiming to conserve this heritage and its potential.

The SPORTS Participation Framework: illuminating the pathway for people with disability to enter into, participate in, and excel at sport.

BACKGROUND: Sports participation for people with disabilities exists at the intersection of health, sport, and education sectors. However, no common framework and language exist to describe the stages of sports participation. OBJECTIVE: To present the background to the SPORTS Participation Framework, and how it can be used to illuminate the path that people with disability may travel to enter into, participate in, and enjoy and excel at all levels of sport. METHOD: The SPORTS Participation Framework includes six stages drawn from mainstream sports pathways and models used to classify barriers to sports participation for people with disabilities: (S) Screening, goal setting and individual preparation, (P) Practitioner led, peer-group sports interventions, (O) Organised junior entry-point sports programs, (R) Recreational sport (non-competitive), (T) Team competition (school/club representation), and (S) State, National, and International competition. RESULTS: For each stage, this paper describes the content of sports activities, the context in which they are performed, key stakeholders, barriers to participation, available evidence, and case studies. CONCLUSIONS: The SPORTS Participation Framework presents a structure to navigate the stages of introducing and promoting lifelong sports participation for people with disabilities. It scaffolds clear communication, governance, and policy across health, sport, and education sectors, and supports clinicians and researchers to address barriers to participation at each stage to improve individual and population-wide participation in sport for people with disabilities.

In this Masterclass paper, we introduce AI and ML concepts, outline recent breakthroughs in AI technologies and their applications, identify the challenges for further progress of AI systems, and discuss ethical issues, clinical and research opportunities, and future perspectives.

Translation and Validation of the Nutrition for Sport Knowledge Questionnaire in Brazil (NSKQ-BR).

This study aimed to translate, culturally adapt, and validate "The Nutrition for Sport Knowledge Questionnaire (NSKQ)" for Brazilian athletes. The NSKQ is an Australian instrument composed of 87 questions divided into six subsections (weight control, macronutrients, micronutrients, sports nutrition, supplementation, and alcohol) designed to assess the nutritional knowledge (NK) of athletes. The translation process followed the recommendations of the World Health Organization for translating and adapting instruments. Semantic validation involved a panel of specialists (n = 21), followed by an assessment performed by a group of adult Brazilian athletes from various sports (n = 17). The reproducibility and internal consistency of the questionnaire were evaluated via a test-retest approach in a sample of adult Brazilian athletes (n = 29) from diverse sports, who completed the Brazilian version of the NSKQ (NSKQ-BR). Overall, the NSKQ-BR presented good internal consistency (α = 0.95) and reproducibility (intraclass correlation coefficient (ICC) = 0.85). The factors "sports nutrition" and "alcohol" showed moderate reproducibility (ICC = 0.74 (0.46-0.88) and ICC = 0.68 (0.33-0.85), respectively). Most athletes (n = 17; 58.6%) presented a medium NK score (50-65%). The NSKQ-BR is available to evaluate the NK levels of Brazilian athletes. The NSKQ-BR presented high internal consistency and reproducibility, validating its applicability among adult athletes across diverse sports.

Field Hip Stability Isometric Test (F-HipSIT): Reliability of Assessing the Hip Posterolateral Muscle Strength in Sports Settings.

CONTEXT: The Hip Stability Isometric Test (HipSIT) is commonly employed in clinical settings for evaluating the hip posterolateral muscle strength. In this study, we introduced the "Field Hip Stability Isometric Test" (F-HipSIT) and assessed the intrarater and interrater reliability of this strength assessment specifically designed for sports settings. DESIGN: Reliability study. METHODS: Two independent raters (A and B) went to athletes' training facilities to conduct 2 sessions of F-HipSIT spaced at least 1 week apart. The average peak force value from 3 valid attempts of each leg was recorded and normalized by the participant's body mass for statistical analysis. RESULTS: Thirty male and 30 female amateur athletes took part in this study. Rater A obtained similar values in the first (0.39 [0.05] and 0.44 [0.07] kg·f/kg) and second (0.39 [0.06] and 0.45 [0.07] kg·f/kg) testing days for men and women, respectively. Rater B also found similar values in the first (0.35 [0.06] and 0.42 [0.08] kg·f/kg) and second (0.36 [0.06] and 0.45 [0.08] kg·f/kg) testing days for men and women, respectively. Excellent intrarater intraclass correlation coefficient (ICC) values were found for men (ICC = .922) and women (ICC = .930), with coefficient of variation of 6% to 8% and minimal detectable change of 0.06 to 0.10 kg·f/kg. The F-HipSIT presented good interrater reliability for men (ICC = .857) and women (ICC = .868), with coefficient of variation of 5% and minimal detectable change of 0.05 to 0.06 kg·f/kg. CONCLUSION: The F-HipSIT intrarater and interrater reliability among male and female recreational athletes supports this field test as a quick and convenient screening tool to monitor hip posterolateral muscle strength in sports settings.

Sports participation in childhood and adolescence and physical activity intensity in adulthood.

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.
