Dessa forma, a tese foi composta por introdução geral, objetivos, capítulos (1, 2 e 3) e conclusão geral. A introdução apresentou considerações sobre a ginástica rítmica, abordou aspectos sobre o comportamento alimentar, a massa óssea e técnica de sua avaliação por meio da ultrassonografia das falanges. Os capítulos 1 a 3 apresentam os artigos de acordo com as normas específicas de periódicos de circulação internacional. As principais conclusões dos artigos foram apresentadas na conclusão geral. As referências bibliográficas foram apresentadas no final de cada capítulo e da tese. Objetivo: O estudo teve como objetivos: (1) avaliar a composição corporal e a massa óssea com o comportamento alimentar em atletas de elite de ginástica rítmica. (2) analisar o crescimento físico e a composição corporal de atletas de ginástica rítmica em relação à maturação somática e (3) avaliar a massa óssea de atletas de ginástica rítmica em relação à idade cronológica e à maturação somática. Materiais e Métodos: Foram incluídas no estudo 136 atletas do sexo feminino de 23 equipes de ginástica rítmica de 10 estados do Brasil, que participam de campeonatos nacionais de alto nível. A faixa etária do grupo estudado variou de 9 a 16 anos de idade (12,3 ± 1,9). Foram avaliadas as medidas de peso, altura e dobras cutâneas e calculados o índice de massa corporal (IMC), altura tronco-cefálica (altura sentada), massa gorda, massa isenta de gordura e percentual de gordura corporal. O valores de peso e altura foram transformados em z escore segundo o padrão da WHO (2007) e Silva et al. (2012). A maturação somática, denominada pico de velocidade de crescimento (PVC), foi determinada por meio de uma equação de regressão múltipla. A classificação do desenvolvimento puberal foi realizada por meio da auto-avaliação do desenvolvimento das mamas. Para avaliar o comportamento alimentar foi adotado o Eating Attitudes Test (EAT- 26). Foi registrado o número de horas de treinamento e de sessões semanais e a idade da menarca através de um questionário. A massa óssea foi avaliada por meio da ultrassonografia nas falanges utilizando-se a terceira geração do equipamento DBM Sonic BP (IGEA, Carpi, Italy). Realizou-se análise descritiva dos dados, com aplicação dos testes t, Shapiro-Wilk, análise de variância ANOVA, qui-quadrado, teste de Tukey e Mann-Whitney, com um nível de significância de 5%. Resultados: Os resultados monstraram que o comportamento alimentar das ginastas de elite não está relacionado com a faixa etária, puberdade, composição corporal e com a massa óssea. Os escores z do peso foram negativos em todas as idades em relação às referências nacional e internacional e da altura ficaram abaixo em todas as idades em relação à internacional e apenas até 12 anos em relação à nacional. O PVC máximo apresentou-se aos 12,1 anos e até quatro anos após observou-se aumento significativo em peso, altura, altura tronco-cefálica, percentual de gordura, massas gorda e isenta de gordura. Foram observadas diferenças significativas na massa óssea no BTT (Bone Transmission Time em ?/s) apenas no momento do PVC e na AD-SoS (Amplitude Dependent Speed of Sound em m/s) dos 12,1 aos 15,4 anos. O maior aumento na massa óssea ocorreu no momento do PVC. Os valores da massa óssea são ascendentes antes do PVC e estáveis após. Conclusão: O estudo constatou comportamento alimentar inadequado e estado nutricional predominantemente baixo, fatores que não foram preditores de atraso no desenvolvimento puberal e não estiveram associados à massa óssea. As ginastas rítmicas demonstraram diminuição da massa óssea, encontraram-se abaixo das referências internacional e nacional para peso, mas para altura abaixo da referência internacional em todas as idades e referência nacionail até 12 anos de idade. Elas apresentaram PVC e menarca em idades semelhantes às referências internacionais, porém com potencial de ganho de peso e altura vários anos após o PVC, o que pode indicar a maturação tardia / Abstract: Structure of the thesis: In this study we chose the "Scandinavian Model", which is called "Alternative Model" in the Graduate Program in Child and Adolescent Health from the Faculty of Medical Sciences, State University of Campinas. Thus, the thesis consisted of general introduction, objectives, chapters (1, 2 and 3) and a general conclusion. A general introduction presented considerations in rhythmic gymnastics, addressed issues on feeding behavior, bone mass and its evaluation by phalanges ultrasound. Chapters 1-3 present the articles in accordance with the specific rules of international journals. The main conclusions of the papers were presented at the general conclusion. References were presented at the end of each chapter and the thesis. Objective: The study aimed to: (1) evaluate the body composition and bone mass with eating behavior of elite rhythmic gymnasts, (2) analyze the physical growth and body composition of rhythmic gymnastics athletes relative to their level of somatic maturation and (3) assess bone mass in elite athletes of rhythmic gymnastics in relation to chronological age and somatic maturation and compare with literature data of female non-athletes of the same age (12.3 ± 1.9). Materials and Methods: The study included 136 female athletes from 23 Rhythmic Gymnastics teams from 10 states of Brazil, who participate in high-level national championships. The age of the study group ranged from 9 to 16 years of age. The measurements of weight, height and thickness skinfolds were done. It was calculated the body mass index (BMI), height-cephalic trunk (sitting height), fat and lean mass, and body fat percentage. The values of weight and height were transformed in score z according tho WHO (2007) reference. Somatic maturation, called peak of height velocity (PHV), was determined by a multiple regression equation. The evaluation of puberty was performed through selfassessment of breast development. It was adopted the Eating Attitudes Test (EAT-26) to evaluate the feeding behavior. We assessed the number of hours of training and weekly sessions and age at menarche by questionnaires. The bone mass was assessed by ultrasound at the phalanges using the third generation of equipment DBM Sonic BP (IGEA, Carpi, Italy). Descriptive analysis, t-tests, Shapiro-Wilk test, ANOVA, qui-squared, Tukey and Mann-Whitney test, with a significance level of 5%, were applied. Results: The results showed that the eating behavior (EAT-26) of elite gymnasts is not related to age, puberty, body composition and bone mass. The z scores for weight were negative during all ages according to both WHO and a Brazilian references, but for height were also negative for all ages according to WHO reference and only until 12 years old according to a Brazilian reference. The maximum PHV curred at 12.1 years and up to four years after it was observed a significant increase in weight, height, trunk-cephalic height, body fat percentage, fat and lean mass. The average age of menarche was 13.2 years. There were significant differences in bone mass by BTT (Bone Transmission Time in ?/S) only at the time of PHV and by AD-SOS (Amplitude Dependent Speed of Sound in m/s) from 12,1 to 15,4 years. The greatest increase in bone mass occurred at the time of PHV. The values of the bone mass are up before the PHV and stable after. Conclusion: The study found inadequate eating behavior and predominant low nutritional status, factors that were not predictors of delayed pubertal development and were not associated with bone mass. The rhythmic gymnasts showed decreased bone mass, were at below the national and international references for weights but heights below the international reference for all ages and national reference until 12 years of age. PHV and menarche were at similar age of to international references, but with potential for weight and height gain several years after the PHV, which indicates late development / Doutorado / Saude da Criança e do Adolescente / Doutora em Ciências

In this diploma work there are compared performances and the difficulty of gymnasts' routines (exercies) at the World level. In rhythmic gymnastics (RG) by monitoring and observation I am going to find out the reason, why the national team members the places in the fifth top ten gymnasts (athlets). In this work I am going to observe one of the best European gymnast A. Maksymenko of Ukraine, who regularly participates in the European, World Championships and in the Olympic Games, and the best Czech gymnast M. Míčková, the competitor without participation in the Olympic Games. Further I am going to observe one of the oldest Austrian gymnast, which is also the Olympic participant, but one of the last advancing, level is more similar exercises Czech gymnastics. By observing videos of gymnasts all around (exercise with hoop, ball, clubs and ribbon) according to the international rules of the RG, I am going to compare complexly the change of the rules which are valid in the contemporary olympic cycle and were valid in the previous rules of the last Olympic cycle. In this analyzes I am going to focus on the routines as a whole, from the perspective of the technical elements (difficulties), dynamic rotating elements with rotations under the apparatus (DER, "risc"), mastery handling, innovative handling...

The aim of the thesis is to analyse and compare two mass gymnastic exercises in terms of spatial choreography, the Spartakiade exercise for younger pupils from 1980 and the mass exercise of the Czech Association of Sport for all teenage pupils, girls and boys from 2012 called Between stars. The thesis also maps the development of mass gymnastic exercises in Czechoslovakia and later in the Czech Republic and generally describes the mass gymnastic exercise and the principles of its creation. The practical part of the work deals with Spartakiade exercise for younger pupils from 1980 and mass exercise of the Czech Association of Sport for all teenage pupils, girls and boys from 2012. The aim of the practical part is to characterise and compare the synchronised exercises in terms of place of the exercise, number of participants, sex, length of the exercise, background music and its intelligibility for the given age, clothing, equipment, spatial choreography and movement difficulty for individuals as well as evaluate content based on creation principles.

Text in English / Rhythmic gymnastics is a demanding sport that requires the athlete to not only execute the moves and elements required with perfection, but also demands a very specific lean body type in order to compete and be successful within the sport. This study explores retired gymnasts’ experiences of competing in rhythmic gymnastics at an elite level, as well as, exploring their experiences in relation to personal body image satisfaction and eating habits when they enter into retirement from the sport. The aim of this study is to provide an understanding of the athlete’s experiences as a rhythmic gymnast, as well as aspects of body image satisfaction and eating habits, following retirement from rhythmic gymnastics. The study provided a semi-structured interview to seven retired elite rhythmic gymnasts from Canada that had competed at provincial, national, and international levels. The data for this in-depth phenomenological study was obtained through the means of the semi-structured interviews to allow for the researcher to obtain an understanding of each of the gymnasts own personal experiences in their retired years. The transcription of each interview was then analysed and coded, first manually and then electronically using the qualitative coding software program ATLAS.ti, into various categories as well as themes found within the data. Findings were interpreted utilising the method of phenomenology explored themes relating to negative body image and poor eating habits both during their athletic career and after they had transitioned out of the sport and into retirement. In addition, the themes suggested that most of the former athletes still related to their elite rhythmic gymnastics identity with respect to their body image even after years of being in retirement. Participants seemed to highlight difficulties with lower self-confidence and self-esteem, as well as struggles regarding the acceptance of their body type and body image, themes also spoke to some participants’ dissatisfaction towards their new body post gymnastics. Ethical approval was obtained and all ethical standards were maintained throughout the duration of the research. / Psychology / M.A. (Psychology)

Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, Durban, South Africa, 2018. / Background: Rhythmic Gymnastics is a sporting discipline involving the use of an apparatus (hoop, ball, clubs, ribbon or rope) to a choreographed routine with music. It requires agility, grace, co-ordination and most of all flexibility. Safety in Rhythmic Gymnastics is questionable when one takes training hours and the extreme flexibility required into consideration. An awareness and understanding of the prevalence and risk factors in Rhythmic Gymnastics will allow event organisers, medical personnel, managers, and coaches to adapt training approaches that will minimize the development of injuries. This information will also aid in developing monitoring systems to prevent adaptation injuries, which will lead to safer training and better management of gymnasts Objectives: This study aimed to investigate the prevalence of musculoskeletal injuries in rhythmic gymnasts within the eThekwini municipality and to identify selected factors associated with an increased risk of injury, in order to improve the management of gymnasts. Methods: A quantitative, descriptive questionnaire-based survey with a Beighton Score assessment was conducted on 67 Rhythmic gymnasts in the eThekwini municipality. Statistical analysis was performed on the results obtained from the questionnaire and the Beighton Score using IBM SSS version 23.0. The Chi-squared test was used (Fisher’s Exact Test was used when the Chi-squared test was violated); A p value of less than 0.05 was considered as statistically significant. Graphical representation of scores by groups was done using various types of tables and graphs. Risk factors for injuries were assessed using logistic regression. Factors were entered individually into the model to determine the co- efficients and odds ratios. Trend tests were computed in order to better assess associations between specific factors and injury. Results: A 100% response rate was achieved in this study. The average age of the participants was 12.3 years (95% CI= 11.7-12.8), average height was 148.5 centimetres (95% CI= 145.1-151.9), average weight was 41.0 kilograms (95% CI= 38.3-43.7), the average level of performance was 4.9 (95% CI= 4.1-5.8) and the average Beighton Score was 5.8 (95% CI= 5.3-6.3). The most commonly previously injured areas were the ankle (n=25) (14.0%), hip and knee (each n=19) (each 10.6%) and the low back (n=18) (10.1%). When considering the two most severe previous injuries the results stay similar, with the ankle being most commonly injured (n=15) (28.0%), followed by the hip (n=9) (17.0%) and the knee (n=6) (11.0%). When considering current injuries, the most commonly injured area is the knee and low back (each n=11) (each 14.5%), and the hip and ankle (each n=9) (each 11.8%). From the above it can be deduced that RG results in more injuries to the lower limb than the upper limb, or core/abdomen or the spine. The most common types of RG injury were muscle strains (n=16) (23.9%), followed by unsure (n=9) (13.4%) and joint sprains (n=8) (11.9%). The most common cause of injury for both previous and current RG injuries were overstretching and overuse ((n=23) (34.3%) for previous injuries; (n=15) (22.4%) for current injuries). Risk factors for injury were significant for the following: training hours per week (36.5 times for 5-8 hours of training per week; 15.7 times for under five hours of training per week; both when compared to more than 8 hours) and lack of balance skills included in RG training (4.5 times more likely than not). When considering treatment option used to keep the body in a good condition, a participant was 4.3 times more likely to utilize home remedies than any other treatment option. Trend tests noted that there is an increase in the mean of injuries as one goes up in age, up until a certain age (13-14 years of age for current injuries; 15-16 years of age for previous injuries), thereafter, there is a decease. Trend tests were also constructed for training hours per week; there was a directly proportional relationship between training hours per week and injury. Conclusion: When considering risk of injury in RG, many of the risk factors cannot be modified (such as age). Those risk factors that can be modified (such as training amount and components of training) should be considered by gymnasts and their coaches in order to implement strategies that could prevent injury. / M

Certain sport environments may contribute to the development of disordered eating and those that heavily emphasize weight and/or body shape can be particularly damaging to an athlete's body image, self-concept, and eating behaviors. In particular, female athletes in collegiate sports are at a greater risk for engaging in unhealthy behaviors because they face both societal pressures from Western culture to be thin, in addition to sport pressures that focus on performance and appearance. According to the American Medical Association almost half of American women are trying to lose weight, illustrating that societal pressures alone to be thin and attractive can influence the development of disordered eating. Athletes are exposed to the same sociocultural pressures as their nonathlete counterparts, and would be expected to have similar feelings about their bodies as women in general. Add subsequent pressures like team "weigh-ins," coaches' body comp preferences, judges' critiques, revealing attire, and endurance/strength demands, and the stage is set for the development of disordered eating. In the current study, participants were 414 Division-I female gymnasts, swimmers/divers, and they completed self-report measures assessing sport pressures, body satisfaction and disordered eating behavior to test Petrie & Greenleaf's etiological model. Results indicate that sport pressures do lead directly to dietary restraint, a precursor to disordered eating, and are not always mediated through internalization and body dissatisfaction. These findings suggest that decreasing and intervening with perceived sport pressures may lessen the risk of female athletes developing an eating disorder.
