ABSTRACT
Sports biomechanics is an interdisciplinary application science that studies human movement. The main purpose of sports biomechanical research is to improve competitive sports performance and prevent sports injuries. This review introduced methods commonly used in biomechanical research, and selected results in biomechanical research on sports performance, training method and sports equipment, so as to provide references for improving the quality of biomechanical research in China. It is hoped that more biomechanical studies will be conducted with the focus on sports performance improvement and injury prevention, using rigorous research design and new technologies to obtain more accurate biomechanical data in human movement, so as to increase the breadth and depth of sports biomechanical researches.
ABSTRACT
Esportes que supervalorizam a estética e o baixo peso corporal são indicados como os com mais incidência de comportamentos alimentares de risco. Diante disto, investigou-se o impacto do esporte competitivo na escolha alimentar de atletas de ginástica artística masculina e, para tanto, foram entrevistados quatro ginastas adultos do gênero masculino. Trata-se de um estudo transversal, com o uso das narrativas como abordagem metodológica. As entrevistas foram obtidas por meio de questões abertas e analisadas à luz da análise de conteúdo, evidenciando dois núcleos temáticos: "regras e estética" e "alimento como merecimento". Os resultados indicam que as escolhas alimentares destes atletas no período competitivo, são desprovidas de prazer, norteadas pela preocupação com a estética, pelo controle exercido pelo técnico e por autorregras. Após a competição, as escolhas aparecem relacionadas ao prazer, livre de regras e vistas como recompensa. Portanto, conclui-se a vulnerabilidade deste grupo às escolhas alimentares prejudiciais à saúde.
In sports which overvalue aesthetics and low body weight athletes have a higher incidence of risky eating behavior. The aim of this study was to identify the impact of the sport environment on food choices of male artistic gymnastics athletes. Four adult male artistic gymnastics athletes were interviewed. It is a cross-sectional study, which used narratives as the methodological approach. The interviews were obtained through open-ended questions and were analyzed though the content analysis, evidencing two thematic nuclei: rules and aesthetic and food as merit. The results indicate that the food choices of these athletes, during the competitive period, are devoid of pleasure, guided by the concern about aesthetics, controlled by the coaches and self-rules. After competition, choices appear to be related to pleasure, free of rules and seen as reward. Therefore, we conclude the vulnerability of this group to harmful food choices.

Las entrevistas fueron obtenidas a través de preguntas abiertas y fueron analizadas a la luz del análisis de contenido, evidenciando dos núcleos temáticos: reglas y estética y alimento como merecimiento. Los resultados indican que las elecciones alimentarias de estos atletas, en el período competitivo, están desprovistas de placer, orientadas por la preocupación por la estética, el control ejercido por el técnico y las autorreglas. Después de la competición, las elecciones se relacionan con el placer, libre de reglas y consideradas como recompensa. Por lo tanto, se concluye la vulnerabilidad de este grupo a las opciones alimenticias perjudiciales para la salud.
