RESUMO

A discussão sobre o racismo no Brasil é um tema relevante e atual, sendo enfrentado cotidianamente pelos afro-brasileiros. No cenário futebolístico não é diferente e este artigo ocupa-se a fazer uma revisão sistemática qualitativa das produções sobre o negro no futebol brasileiro, publicadas em periódicos científicos com escopo na Educação Física que, no Qualis/Capes do quadriênio 2013-2016, foram classificadas pela área 21 no extrato B2 ou superior. Divididos em cinco temáticas, encontrou-se resultados específicos: os jogos, Preto X Branco buscaram reforçar a integração racial; a imprensa negra atuava no combate ao racismo; a culpa do jogador negro, Barbosa, na derrota de 1950 não se deveu às análises esportivas à época; a cultura negra como atributo fundamental no estilo brasileiro de jogar; por fim, a discriminação racial no meio é uma prática recorrente e as autoridades pouco têm feito para combatê-lo.


Racism in Brazil is a relevant and current discussion, being faced daily by the Afro-Brazilians. As it also happens in the football scenario, this article engages a systematic qualitative review of the scientific productions concerning black people in Brazilian soccer published in academic journals focused on Physical Education, classified in area 21, stratum B2 or higher in Qualis/Capes four-year period 2013-2016. Five subjects compose the specific results found: first, the Black X White games sought to reinforce racial integration; second, the black press acted to fight racism; third, Barbosa's fault, a black player, in 1950's defeat was not due to sports analyses at the time. Fourth, black culture is a fundamental attribute to the Brazilian play style, and lastly, racial discrimination in this environment is an iterant practice, and authorities have done little to fight it.

RESUMO

O estudo busca analisar como o esporte é tratado nos ordenamentos legais e dispositivos políticos do Brasil e da Espanha. Para tanto foi realizado um estudo comparado através de levantamento documental e revisão bibliográfica. Observou-se que o esporte aparece como dever do Estado em ambos os países, entretanto, a legislação infraconstitucional e os dispositivos, em quase sua totalidade, caminha no sentido de consolidar as práticas esportivas como mercadorias.


The study seeks to analyze how sport is treated in the legal systems and political provisions of Brazil and Spain. For this purpose, a comparative study was carried out through documentary survey and bibliographic review. It was observed that sport appears as a duty of the State in both countries, however, the infra-constitutional legislation and the devices, in almost their entirety, are moving towards consolidating sports practices as commodities.

RESUMO

Este estudo teve como objetivo interpretar e analisar como o Jornal Folha de São Paulo retratou os Jogos Olímpicos Rio 2016 como evento esportivo na cobertura esportivo-midiática da Folha de São Paulo. Este artigo é resultado de uma pesquisa qualitativa descritiva, tendo como corpus o Jornal Folha de São Paulo, referente às edições de 1º de julho a 30 de setembro de 2016. A análise deu-se através de períodos temporais, de acordo com o que estava acontecendo em cada período. A cobertura do pré-evento muito se preocupou com o término das estruturas e se o país tinha condições de sediar JO. Por outro lado, a cobertura durante o evento mostrou que o país tinha condições de sediar megaeventos. Por fim, a cobertura do pós-evento retratou o legado que os jogos deixaram para o país sede das OlimpíadasRio-2016.


This study aimed to interpret and analyze how the newspaper Folha de São Pauloportrayed Rio 2016 Olympic Games as a sports event in the sports media coverage of Folha de São Paulo. This paper is the result of a qualitative descriptive research, using as corpusthe newspaper Folha de São Paulo, editions from July 1stto September 30thof 2016. The analysis was carried out through time periods, according towhat was happening in each period. The pre-event coverage was really concerned about the structure completion and whether the country was ready to host the OG. On the other hand, the coverage during the event showed that the country had the ability to host mega-events. Lastly, the post-event coverage portrayed the legacy that the games left to the host country of Rio 2016 Olympics.

RESUMO

Mesmo que haja algumas pesquisas e estudos, nos âmbitos acadêmico e científico, referentes à gestão, uso e apropriação de espaços públicos nos contextos do esporte e do lazer, notam-se, ainda, lacunas pouco exploradas, como a gestão da informação e a difusão adequada do conhecimento sobre a temática, envolvendo as Políticas Públicas. Desta forma, este estudo, de natureza qualitativa, teve como objetivo, realizar uma revisão sistemática de literatura sobre a produção científica recente, apresentando o estado da arte sobre Políticas Públicas e a gestão de espaços públicos nos contextos do esporte e do lazer. Para tanto, a busca foi realizada nas seguintes bases de dados: Scopus, SPORTDiscus, Web of Science, Pro Quest e SciELO, utilizando os termos booleanos a seguir: "sport and leisure management" OR "sport space" OR "leisure space" OR "sport equipment" OR "leisure equipment" OR "public Sport policy" OR "public leisure policy". Os artigos analisados abrangeram diferentes áreas do conhecimento, tal como, as Ciências do Esporte, Geografia, Arquitetura e Urbanismo e Sociologia. Os dados foram analisados por meio da Técnica de Análise de Conteúdo. Com base nos resultados, pode-se perceber que o tema referente às Políticas Públicas nos contextos do esporte e do lazer tem sido focalizado atualmente, nos estudos, entretanto, os espaços públicos neste contexto ainda são tratados de forma secundária. Este campo de estudo carece de novas pesquisas, com a intenção de aprofundar as investigações sobre a temática.


Despite some research and studies, in academic and scientific fields, and concerning the management, use and appropriation of public spaces in sports and leisure contexts, there are still some gaps that have been insufficiently explored, such as information management and the appropriate knowledge diffusion on the subject, among Public Policies. Thus, this qualitative study aimed to conduct a systematic review on recent scientific production, presenting the state of the art on Public Policies and public spaces management regarding sport and leisure contexts. A search was performed in the following databases: Scopus, SPORTDiscus, Web of Science, Pro Quest and SciELO. The keywords and Boolean terms were: "sport and leisure management" OR "sport space" OR "leisure space" OR "Sport equipment" OR "leisure equipment" OR "public sport policy" OR "public leisure policy". The papers analyzed covered different knowledge areas, such as Sport Sciences, Geography, Architecture and Urbanism, and Sociology. The collected data were analyzed using the Content Analysis Technique. Based on the results, it can be noticed that the theme regarding Public Policies in sport and leisure contexts is focused among the studies; however, public spaces are still treated in a secondary way. This study field needs further researches, with the intention of deepening the knowledge on the subject.

RESUMO

Aim: In this cross-sectional study, we evaluated the oral hygiene habits, oral health conditions, and the perception about the influence of oral health conditions on the physical performance of youth and professional volleyball and soccer athletes. Methods: A total of 96 male athletes participated: 48 volleyball players (25 youth and 23 professional players); and 48 soccer players, of whom 22 were youth, and 26 were professional players. We analyzed the oral hygiene and oral health condition (daily toothbrush, flossing, mouthwash, dental plaque, orthodontic treatment, dental/facial trauma, temporomandibular dysfunction, malocclusion, and the athletes' perception about the influence of oral health conditions on the physical performance (yes or no)). Comparisons were made between the youth and professional athletes for each sport (volleyball and soccer). According to each variable, we applied the Chi-square, Fisher's Exact, and Mann-Whitney tests. Results: For soccer athletes, we found significant differences between youth and professionals for: flossing (p=0.014), orthodontic treatment (p=0.028), dental/facial trauma (p=0.041), and the athletes' perception about oral health and physical performance (p<0.001). Considering the category (youth and professional) regardless of the type of sport, we found significant differences for dental plaque (p=0.024) and dental/facial trauma (p=0.005). According to the sport (volleyball and soccer), independent of the category, we found significant differences for daily brushing, dental/facial trauma (p=0.005), and the athletes' perception about oral health and physical performance (p=0.006). Conclusion: We concluded that the surveyed athletes had good oral health and believed that oral health can influence sports performance

RESUMO

The changes in the physical properties and functional shifts of middle and long distance runners in Tbilisi and Bakuriani conditions during the identical physical exercises are given in this paper. For comparison the analogous data of judokas are presented. The difference between the background indices (Tbilisi) and in the conditions of Bakuriani has been established during training and the state of rest. Based on the relief peculiarities of Georgia, the action of trainings conducted at different heights (Tbilisi - 550 m and Bakuriani - 1750 m from sea level) on heart rate and respiratory rate, lung vital capacity at the state of rest, the hand and lumbar muscles strength, general and special endurance of the high qualification sportsmen (among them 32 athletes and 40 judokas) have been studied. The above-said data were recorded in accordance with the training processes (preparatory, basic and transition) at the state of rest and in the intervals between physical exercises (warming up, control and official competitions) and in the first minutes of recovery period after completing the exercises. Also, the duration of adaptation period was established at the state of rest and physical training of sportsmen, and there were almost no data in the literature about this till conducting Olympic Games in Mexico City (1968). The observations were conducted on athletes and judokas in Tbilisi (550 m from sea level) and Bakuriani (1750 m). The training sessions lasted 20-22 days. Thus, the features of physical and functional shifts in athletes are revealed, depending on various types of sports employment, training periods, rest and climatic conditions that must be taken into account when conducting sports training.

RESUMO

Data analysis plays an increasingly valuable role in sports. The better the data that is analysed, the more concise training methods that can be chosen. Several solutions already exist for this purpose in the tennis industry; however, none of them combine data generation with a wristband and classification with a deep convolutional neural network (CNN). In this article, we demonstrate the development of a reliable shot detection trigger and a deep neural network that classifies tennis shots into three and five shot types. We generate a dataset for the training of neural networks with the help of a sensor wristband, which recorded 11 signals, including an inertial measurement unit (IMU). The final dataset included 5682 labelled shots of 16 players of age 13-70 years, predominantly at an amateur level. Two state-of-the-art architectures for time series classification (TSC) are compared, namely a fully convolutional network (FCN) and a residual network (ResNet). Recent advances in the field of machine learning, like the Mish activation function and the Ranger optimizer, are utilized. Training with the rather inhomogeneous dataset led to an F1 score of 96% in classification of the main shots and 94% for the expansion. Consequently, the study yielded a solid base for more complex tennis analysis tools, such as the indication of success rates per shot type.

RESUMO

This article aims to describe the reasons for sport participation in the Brazilian adult population according to gender, age and schooling level. This is a cross-sectional study with data from a National Household Sample Survey - 2015. The reasons to practice or not practice sports in the previous year were obtained by questionnaire with predetermined answer options. All analyses were performed in Stata 12.1 and stratified by gender. The prevalence of sports participation for men and women were 31.7% and 16.9%, respectively. The most frequent reasons for sports participation among men were: having fun, quality of life and performance. Among women, the most frequent reasons were: quality of life, performance and medical recommendation. Regarding reasons for not practicing sports, the most reported ones were: lack of time (38.8% for men and 37.8% for women), not enjoying (34.8% for men and 35.3% for women) and health problem (20.3% for men and 17.9% for women). The study findings showed the most frequent reasons for sport participation in Brazil. Understanding these reasons and how they affect different age ranges and educational levels may contribute to improve strategic planning to promote sports in middle-income countries.

RESUMO

This study aimed to identify the defensive contents and teaching approaches preferred by handball coaches of school teams. Eleven coaches from a city in the State of São Paulo were interviewed. The discourses from the semi-structured interviews were analyzed based on the Collective Subject Discourse method. Coaches revealed that match-up, base position, coverage, and spatial occupation are the main individual defensive contents and use the teaching through games situations, technique approach, and teaching through games. The main group defensive content mentioned by the coaches is the match-up changes, mutual cover, and defensive systems, for which they preferred the teaching through games situations, teaching through games and technique approach. The findings show that although they are content of the same phase of the game, there is a preference for different teaching approaches. On the other hand, there seems to be inconsistency with the choice of the technique approach when it comes to the teaching of individual defensive contents, mainly because they are related to the players' decision-making. Such findings will contribute to the teaching of handball in school teams and with reflections for the teaching of the different specific contents, raising new discussions.

RESUMO

Importance: Previous studies have shown reductions in self-reported physical activity levels in children associated with implementation of COVID-19 mitigation measures, and data on objectively assessed health parameters are limited. Objective: To examine the association of COVID-19 mitigation measures with changes in cardiorespiratory fitness (CRF) measures and body mass index (BMI) among primary schoolchildren. Design, Setting, and Participants: This cohort study included children aged 7 to 10 years from 12 randomly selected primary schools in urban and rural districts of Klagenfurt, Austria. Baseline CRF and BMI measurements were obtained in September 2019 before COVID-19 mitigation measures were implemented, and follow-up measurements were obtained in June and September 2020. Exposures: COVID-19 mitigation measures. Main Outcomes and Measures: Cardiorespiratory fitness was measured with a 6-minute endurance run test. Height and weight were objectively measured. Standard deviation scores were calculated for CRF and BMI. Changes over time were analyzed using analyses of variance. Secondary analyses were performed for subgroups stratified by sex. Results: A total of 764 children (383 girls [50.1%]) aged 7 to 10 years had all measurements completed. From September 2019 to September 2020, CRF SD scores changed by -1.06 (95% CI, -1.13 to -1.00), with a similar decrease in both boys and girls. Body mass index SD scores had increased by 0.12 (95% CI, 0.06-0.16) in June 2020 and by 0.16 (95% CI, 0.12-0.20) in September 2020 compared with September 2019. The increase in BMI SD scores (from September 2019 to September 2020) was greater among boys (0.23; 95% CI, 0.18-0.29) than among girls (0.09; 95% CI, 0.04-0.15). During the 1-year period, the percentage of children with overweight or obesity increased from 20.3% (155 children) to 24.1% (184 children) (difference, 3.8% [29 children]). Conclusions and Relevance: In this cohort study of children in Austria, COVID-19 mitigation measures were associated with decreases in CRF measures and increases in BMI. The findings suggest that collaborative efforts are needed to reverse these changes in children's health to prevent long-term negative health outcomes.

RESUMO

In recent years, the application of the gradient boosting-back propagation (GB-BP) neural network algorithm in many industries has brought huge benefits, so how to combine the GB-BP neural network algorithm with sports has become a research hotspot. Based on this, this paper studies the application of the GB-BP neural network algorithm in wrestling, designs the sports athletes action recognition and classification model based on the GB-BP neural network algorithm, first analyzes the research status of wrestling action recognition, and then optimizes and improves the shortcomings of action recognition and big data analysis technology. The GB-BP neural network algorithm can realize the accurate recognition and classification of wrestlers' training actions and carry out big data mining analysis with known action recognition, so as to achieve accurate classification. The experimental results show that the model can play a good role in wrestling and effectively improve the efficiency of wrestlers in training.

RESUMO

Sufficient daily physical activity is associated with many positive mental, physical, and societal benefits in children. Unfortunately, most children worldwide do not achieve recommended levels of daily physical activity (PA), and a majority of evidence is from Western countries and based on subjective measures. This study examined the prevalence and correlates of objectively measured PA levels among Omani children in 2017 (pre-pandemic). A two-stage cluster sampling was used to recruit the 4th grade children across five regions of Oman. A final analytic sample included 1053 children (504 boys, 549 girls) with a mean age of 9.21 years old. PA was objectively measured using a wrist-worn Polar Active Watch during three consecutive school days. Screen-based sedentary behaviors and other PA-related behaviors were subjectively measured. On average, boys were less sedentary and more active, with a greater likelihood of meeting current recommendations when compared with girls. The self-reported time spent in screen-based sedentary behaviors was relatively low for both boys and girls and was not associated with PA; however, sports team participation was associated with a greater likelihood of meeting the current recommendation. The present study provides empirical data on objectively measured PA in Omani children. The gender disparities concerning daily PA, including sports team participation, should receive further attention.

RESUMO

STUDY DESIGN: A cross-sectional study. OBJECTIVE: The purpose of this large cohort study was to assess the prevalence of low back pain (LBP) among young players participating in several types of sports. SUMMARY OF BACKGROUND DATA: LBP is a significant problem among young sports players. Sport discipline among young players is thought to be associated with LBP. However, similar previous studies did not specifically analyze LBP by age and sex. METHODS: A cross-sectional study was conducted with young sports players (ages 6-15 years, n = 7277) using a self-reported questionnaire. The prevalence of LBP was assessed using the variables of age, sex, and sport discipline. RESULTS: The point prevalence of LBP among young sports players was 5.0%. The participants between 6 and 8 years' old had the lowest prevalence of LBP (0.4%-1.3%), which increased with aging and reached the highest proportion of 13.5% to 14.8% at 13 to 14 years. Furthermore, female players had significantly higher proportions of LBP than male players (8.1% vs. 3.7%). Regarding sport discipline, the prevalence of LBP was higher in basketball, handball, and volleyball. CONCLUSION: The prevalence of LBP among young sports players was different for age, sex, and sport discipline. Further studies are needed to clarify the association of sport-specific movements to LBP in each sport discipline. This may assist in developing programs or strategies for preventing LBP among young sports players.Level of Evidence: 3.

RESUMO

Throughout the life, a person's working capacity is variable. It is influenced by a wide range of factors, both external and internal, which are difficult to take into account in various studies. An approximation of the density function of the given distribution, based on the assumption of the random nature of the physical condition, depending on a number of different reasons, among competitors and the hypothesis of the asymmetric distribution of athletes' achievements, shown at different ages, is formed. Optimum parameters of a log-normal distribution describing the working capacity of a person according to his or her age are determined by using the least squares method. This is a comparative analysis of the received model and the previously known methods, which were created by Litvinov and Spiridonov. The study has showed the validity of the method for determining age coefficients and the possibility of its practical application.

RESUMO

Athletes are exposed to a tremendous amount of stress, both physically and mentally, when performing high intensity sports with frequent practices, pushing numerous athletes into choose to use ergogenic aids such as caffeine or ß-alanine to significantly improve their performance and ease the stress and pressure that is put onto the body. The beneficial or even detrimental effects of these so-called ergogenic aids can be appreciated through the use of numerous diagnostic tools that can analyze various body fluids. In the recent years, saliva samples are gaining more ground in the field of diagnostic as it is a non-invasive procedure, contains a tremendous amount of analytes that are subject to pathophysiological changes caused by diseases, exercises, fatigue as well as nutrition and hydration. Thus, we describe here the current progress regarding potential novel biomarkers for stress and physical activity, salivary α-amylase and salivary cortisol, as well as their use and measurement in combination with different already-known or new ergogenic aids.

RESUMO

Wearable and Internet of Things (IoT) technologies in sports open a new era in athlete's training, not only for performance monitoring and evaluation but also for fitness assessment. These technologies rely on sensor systems that collect, process and transmit relevant data, such as biomarkers and/or other performance indicators that are crucial to evaluate the evolution of the athlete's condition, and therefore potentiate their performance. This work aims to identify and summarize recent studies that have used wearables and IoT technologies and discuss its applicability for fitness assessment. A systematic review of electronic databases (WOS, CCC, DIIDW, KJD, MEDLINE, RSCI, SCIELO, IEEEXplore, PubMed, SPORTDiscus, Cochrane and Web of Science) was undertaken according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. From the 280 studies initially identified, 20 were fully examined in terms of hardware and software and their applicability for fitness assessment. Results have shown that wearable and IoT technologies have been used in sports not only for fitness assessment but also for monitoring the athlete's internal and external workloads, employing physiological status monitoring and activity recognition and tracking techniques. However, the maturity level of such technologies is still low, particularly with the need for the acquisition of more-and more effective-biomarkers regarding the athlete's internal workload, which limits its wider adoption by the sports community.

RESUMO

BACKGROUND: Exercise-based rehabilitation targeting intersegmental control has high success rates and fast recovery times in the management of athletic groin pain (AGP). The influence of this approach on hip strength and lower limb reactive strength and how these measures compare with uninjured athletes (CON) remain unknown. Additionally, the efficacy of this program after return to play (RTP) has not been examined. PURPOSE: First, to examine differences in isometric hip strength, reactive strength, and the Hip and Groin Outcome Score (HAGOS) between the AGP and CON cohorts and after rehabilitation; second, to examine the relationship between the change in HAGOS and the change in strength variables after rehabilitation; last, to track HAGOS for 6 months after RTP. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: A total of 42 athletes diagnosed with AGP and 36 matched controls completed baseline testing: isometric hip strength, lower limb reactive strength, and HAGOS. After rehabilitation, athletes with AGP were retested, and HAGOS was collected at 3 and 6 months after RTP. RESULTS: In total, 36 athletes with AGP completed the program with an RTP time of 9.8 ± 3.0 weeks (mean ± SD). At baseline, these athletes had significantly lower isometric hip strength (abduction, adduction, flexion, extension, external rotation: d = -0.67 to -1.20), single-leg reactive strength (d = -0.73), and HAGOS (r = -0.74 to -0.89) as compared with the CON cohort. Hip strength (d = -0.83 to -1.15) and reactive strength (d = -0.30) improved with rehabilitation and were no longer significantly different between groups at RTP. HAGOS improvements were maintained or improved in athletes with AGP up to 6 months after RTP, although some subscales remained significantly lower than the CON group (r = -0.35 to -0.51). Two linear regression features (hip abduction and external rotation) explained 11% of the variance in the HAGOS Sports and Recreation subscale. CONCLUSION: Athletes with AGP demonstrated isometric hip strength and reactive strength deficits that resolved after an intersegmental control rehabilitation program; however, improved hip strength explained only 11% of improvement in the Sports and Recreation subscale. HAGOS improvements after pain-free RTP were maintained at 6 months.

RESUMO

Furosemide is included in the World Anti-Doping Agency's (WADA) list of prohibited substances because it can be used by athletes to mask the presence of performance-enhancing drugs in urine and/or excrete water for rapid weight loss. But how effective is furosemide in masking prohibited substances in urine? Based on the pharmacology and the available literature, we conclude that the masking effect of furosemide is limited. Furosemide is a doping agent that is mainly relevant for sports with weight categories.

RESUMO

Urban seismology has gained scientific interest with the development of seismic ambient noise monitoring techniques and also for being a useful tool to connect society with the Earth sciences. The interpretation of the sources of seismic records generated by sporting events, traffic, or huge agglomerations arouses the population's curiosity and opens up a range of possibilities for new applications of seismology, especially in the area of urban monitoring. In this contribution, we present the analysis of seismic records from a station in the city of Brasilia during unusual episodes of silencing and noisy periods. Usually, cultural noise is observed in high-fequency bands. We showed in our analysis that cultural noise can also be observed in the low-frequency band, when high-frequency signal is attenuated. As examples of noisy periods, we have that of the Soccer World Cup in Brazil in 2014, where changes in noise are related to celebrations of goals and the party held by FIFA in the city, and the political manifestations in the period of the Impeachment trial in 2016, which reached the concentration of about 300,000 protesters. The two most characteristic periods of seismic silence have been the quarantine due to the COVID-19 pandemic in 2020, and the trucker strike that occurred across the country in 2018, both drastically reducing the movement of people in the city.

RESUMO

CONTEXT: The Landing Error Scoring System (LESS) screens for risk of noncontact anterior cruciate ligament injury. The LESS requires individuals to jump forward from a 30-cm box to a distance of 50% of their body height. However, different landing distances have been cited in the scientific literature. OBJECTIVE: To examine whether landing distance influences LESS outcomes. DESIGN: Cross-sectional study. SETTING: Laboratory. PARTICIPANTS OR OTHER PARTICIPANTS: Seventy young active individuals (34 males, 36 females). INTERVENTION(S): Participants performed 3 × 30-cm jump-landing tasks under 2 landing conditions in randomized order: (1) 50% of body height (d50%), (2) self-selected distance (dss). MAIN OUTCOME MEASURE(S): Mean LESS scores, proportions of individuals categorized at high (LESS: ≥ 5 errors) and low (LESS: < 5 errors) injury risk, and landing distances were compared between conditions using generalized estimating equations. Consistency of risk categorization was examined using odds ratios (ORs) and McNemar tests. McNemar and Wilcoxon signed rank tests were used to compare the occurrence of specific LESS errors. RESULTS: Participants landed closer to the box under the dss condition (difference = -23.28 [95% CI = -20.73, -25.81]%, P < .001). Group mean LESS scores (difference = -0.01 [95% CI = -0.59, 0.57] error, P = .969) and risk categorization (OR = 0.94 [95% CI = 0.47, 1.88], P = .859) were similar between conditions. However, individual-level risk categorization was inconsistent in 33% of participants, as was the occurrence of specific errors. CONCLUSIONS: Using dss during the LESS might lead to different LESS errors and risk categorizations at an individual level than using d50%. Given that individual LESS scores are of primary interest in clinical and sport settings and the injury-risk threshold has not been validated for dss, we recommend use of the original LESS protocol. When only group mean LESS scores or proportions of at-risk individuals are of interest, using dss is feasible to facilitate the testing of large cohorts.
