The objective of this study was to evaluate the color (∆E*) and the degradation of the strength of chain elastics when submitted to different rinses. Forty segments of aesthetics chain elastics (American Orthodontics) were maintained extended in distilled water at 37°C. The elastics (n=10) were immersed twice a day for 60 seconds each in the following solutions: Chlorhexidine Gluconate; Grapefruit essential oil; Ginger and distilled water. The readings were performed in the following times: initial, 24 hours, 7, 14, 21, and 28 days using universal testing machine and spectrophotometer. The force degradation data were analyzed by mixed models for repeated measurements in time, and the data from ∆E* were evaluated by Kruskal Wallis and Dunn and Friedmann and Nemenyi (α=5%). Except for the group immersed in Ginger, there was a significant decrease in force degradation after 24 hours (p0.05); after 7 days there was force recovery for all solutions. For ∆E* it was found that there was no statistically significant difference between the solutions for most of the time. However, after 28 days Chlorhexidine showed less ∆E* than the other solutions. It is concluded that the time in which the elastic chain is stretched influences the degradation of strength; immersions in rinses with the exception of ginger solution degrade the strength after 24 hours and; there is color change for all solutions after 28 days.
A melhora significativa dos resultados da Ginástica Artística (GA) brasileira está diretamente atrelada a implementação e aprimoramento de métodos de planejamento, monitoramento e controle da preparação esportiva. Deste modo, o objetivo dessa pesquisa foi verificar a análise e registro do planejamento, monitoramento e controle do processo de preparação esportiva de ginastas. Para tal, utilizou-se de questionário, aplicado a nove treinadores/as de equipes de GA competitivas da Região Metropolitana de Campinas (RMC). O resultado revela que um alto percentual de técnicos analisam aspectos relacionados a preparação física, técnica e psicológica na preparação esportiva, no entanto há um baixo percentual de registro desses dados, dificultando a análise de dados do sistema de preparação esportiva.
