“…It is therefore recommended that when optimising simulations of swinging skills a minimum robustness requirement of 20 ms is included. This result is in agreement with Yeadon and Brewin (2003) who found that timing perturbations of 15 -30 ms to changes in body configurations resulted in the range of residual swing in the final handstand position of elite performances of the backward longswing on rings. Similarly, Hiley and Yeadon (2007) found that release windows comparable to actual performances of asymmetric bar dismounts were obtained from optimisations robust to 20 ms perturbations.…”

The dismount from the high bar is one of the most spectacular skills performed in Men's Artistic Gymnastics. Hiley and Yeadon (2005) optimised the technique in the backward giant circle prior to release using a computer simulation model to show that a gymnast could generate sufficient linear and angular momentum to perform a triple piked backward somersault dismount with a sufficiently large release window (the period of time during which the gymnast could release the bar and successfully complete the dismount). In the present study it was found that when the timing of the actions at the hip and shoulder joints from the optimum simulation were perturbed by 30 ms the resulting simulation could no longer meet the criteria for sufficient aerial rotation and release window. Since it is to be expected that a gymnast's technique can cope with small errors in timing for consistent performance, a requirement of robustness to timing perturbations should be included within the optimisation process. When the technique in the backward giant circle was optimised to be robust to 30 ms perturbations it was found that sufficient linear and angular momentum for a triple piked dismount could be achieved with a realistic release window.

“…Esses eventos ocorrem devido ao tipo de sobrecarga biomecânica exercida pelos aparelhos sobre as estruturas. Yeadon e Brewin (22) descrevem, nas argolas, considerado aparelho de apoio e suspensão, neste estudo, a importância da execução de giros e exercícios estáticos, que requerem grande força de musculatura superior para suportar o peso corporal e manter o máximo de alinhamento entre quadril e ombros, o que aumenta a possibilidade de lesões nos membros superiores.…”

Introdução: Os níveis de exigência biomecânica devidos ao alto grau de dificuldade na realização de gestos fazem da ginástica artística (GA) uma modalidade com elevado risco de lesões. Assim, é necessário que os aspectos a elas relacionados sejam controlados. Objetivo: Analisar a ocorrência de lesões na Ginástica Artística, associando-as a fatores de risco específicos da modalidade e do atleta, a partir de inquérito de morbidade referida. Métodos: Foram entrevistados 54 ginastas, recrutados ao acaso, classificados segundo o nível competitivo em duas categorias: regional e nacional. Utilizou-se o inquérito de morbidade referida (IMR) com a finalidade de reunir dados sobre a natureza da lesão, região corporal e aparelho ginástico. Os dados foram organizados e apresentados sob a forma de distribuição de freqüências e as variáveis, analisadas segundo nível de associação a partir do teste de Goodman para contrastes entre populações multinomiais, considerando significante o valor P < 0,05. Resultados: Presença de lesão durante a temporada foi relatada por 39 (71,70%) atletas, sendo 22 (56,41%) mulheres e 17 (43,59%) homens. Nas categorias regional masculino e feminino e nacional feminino, a maior ocorrência de lesões foi de origem articular, correspondendo a 55,56%, 50% e 45,45% do total, respectivamente. Para o sexo feminino nacional, os membros inferiores foram os mais referidos (68,18%) e, em ambas as categorias, as lesões ocorreram nos aparelhos de saltos (79,41%), enquanto que no sexo masculino nacional o maior número de agravos foi verificado nos aparelhos de apoio e suspensão (72%). Conclusões: Há elevada freqüência de lesões, acometendo principalmente articulações e membros inferiores, sendo os aparelhos de saltos os mais referidos quanto à ocorrência de acometimentos. Foi observado também que, quanto maiores as exigências de desempenho técnico, maior a freqüência de lesões.Palavras-chave: traumatismo em atletas, fatores de risco, epidemiologia analítica. ABSTRACT Introduction:The levels of biomechanical demands due to the high level of difficulty in the gestures accomplishment make Artistic Gymnastics (AG) a modality with high risk of injuries. Thus, it is necessary that the aspects concerned with them are controlled. Objective: To analyze the occurrence of injuries in artistic gymnastics, associating them with specific risk factors of the modality and of the athlete from reported morbidity survey. Methods: 54 gymnasts randomly recruited have been interviewed and classified according to their competitive level into two categories: regional and national. The reported morbidity questionnaire (RMQ) was used with the purpose to collect data on the injury's nature, body region and gymnastic apparatus. Data were organized and presented under frequency distribution and analyzed variables. The variables were analyzed according to their level of association from the Goodmann's test for contrasts between multinomials populations considering significant value p<0.05. Results: 39 (71.70%) athletes have reported injury du...

“…The method described in the current study may be used to collect data on a wide group of elite gymnasts of both sexes to define some "gold standard execution", with parameters related to individual anthropometric measures. Furthermore, the same technical parameters could be used in the biomechanical approaches to gymnastic performance, improving the modeling and optimizing the algorithms of execution [8][9][10][11]22 .…”

“…The gymnasts are therefore required several hours of technical, strength, and flexibility training to obtain the best results 3 . Previous studies mostly analyzed the risk and the incidence of injuries during the execution of this closed-skill sport [4][5][6][7] , and investigated the biomechanical characteristics of several technical elements [8][9][10][11][12][13] . Also, the anthropometric and physical features of elite gymnasts have been studied 1,14 .…”

Introduction: Gymnastic is the most ancient and spectacular closed skills sport. Nonetheless, often technical parameters of execution are taught only by trainer experience. Thus, a lack of objective data about gymnastic performance (kinematics references) is present. Objective: In the current study, we wanted to quantify linear and hyperextension back movements during the performance of backward handsprings. Methods: A non invasive detection of backward handsprings was made using a 3D optoelectronic instrument. Thirteen spherical retro-reflective markers (diameter 1 cm) were positioned on the body of 9 experienced gymnasts: right and left lateral malleolus, fibular head, greater trochanter, acromion, olecranon, styloid process of the ulna; vertex. In the same session and after a warming-up period, each participant performed 15 repetitions of backward handsprings. Ten repetitions were analyzed, and the 3D tracks of the 13 landmarks measured. Results: On average, men performed longer backward handsprings than women (men, 122% of height; women, 98%); women attained a larger vertical height (women, 62% of height; men, 58%). The lower limb arrangement was homogenous among the gymnasts: posterior knee angles ranged between 80° and 118°. No lower limb abduction was observed: knee width was 7 cm smaller than intertrochanter width; ankle width was 8 cm smaller than knee width. At take-off, the trunk-thigh angle showed an excellent body alignment, with values very close to 180°. Women performed the handstand phase with closer wrists than men (men, 134% of shoulder width; women, 121%). Conclusion: The results may offer data to improve learning, defining golden standard execution taken from high level gymnasts with few injuries.
