Resumo (PT): O objetivo deste estudo foi investigar o comportamento do perfil Força-Velocidade (F-V) vertical durante o Counter Movement Jump de atletas de 1ª divisão e elite de Ginástica Acrobática antes e após a aplicação de um programa de treino durante um período transitório especial e a sua interferência na execução do mortal à frente. 28 ginastas de 1ª divisão e elite com idades compreendidas entre 11 e 25 anos foram divididos aleatoriamente em grupo controlo (GC) de ginastas volantes (n=4), grupo intervenção (GI) de ginastas volantes (n=7), GC de ginastas bases (n=9) e GI de ginastas bases (n=8). MyJump2 foi o instrumento utilizado para avaliar o desequilíbrio entre F-V (F-V Imb). Foi utilizada a Anova Mista para 2 momentos de avaliação para todas as variáveis do perfil F-V (P≤0.05) e foi calculado o Effect size (ES) de Hopkins (2004). Por fim, realizaram-se gravações do mortal à frente e um questionário para compreender a influência da altura de salto na perceção de execução do elemento após o programa (análise através de um teste T de medidas repetidas). Não houve diferenças significativas entre os grupos ao longo do tempo. Contudo, algumas das variáveis intra grupo melhoraram de forma relevante. Os ginastas bases do GI melhoraram 1.06 (1.56) cm na altura de salto e 23.75 (4.16) % no F-VImb com ES de -1.19 e 100% de probabilidade de o programa ter tido um efeito negativo já que o objetivo era diminuir este valor. O F-VImb dos ginastas volantes do GI não melhorou, contudo, a altura de salto aumentou 0.86 (0.05) cm e os valores de força melhoraram 5.59 (5.47) N/kg com ES de 1.29 e 90% de probabilidade de o programa ter tido um efeito positivo nesta variável. Por fim, houve diferenças significativas no GI (P=0.013) na análise da perceção da execução do mortal à frente. Concluímos que o programa de treino de 9 semanas foi eficaz, já que, apesar dos pesos dos ginastas dos GI apresentarem diferenças significativas durante o período transitório especial no qual se encontravam, o programa de treino conseguiu mitigar os efeitos negativos desse aumento de peso através da melhoria das variáveis mecânicas do perfil F-V, da altura de salto e da capacidade específica de salto associada a esta disciplina gímnica.
Abstract (EN): The purpose of this study was to investigate the vertical Force-Velocity (F-V) profile behavior during the Counter Movement Jump of 1st division and elite Acrobatic gymnasts before and after the application of a training program during a special transition period and its interference in front tuck execution. 28 acrobatic gymnasts from 1st division and elite groups with ages between 11 and 25 years old were randomly divided in top gymnasts control group (CG) (n=4), top gymnasts intervention group (IG) (n=7), base gymnasts CG (n=9) and base gymnasts IG (n=8). MyJump2 was the instrument used to evaluate the F-V Imbalance (F-V Imb). A Mixed Anova for 2 evaluation moments was used for all F-V profile mechanical variables (P≤0.05). Hopkins (2004) effect size (ES) was used to calculate the magnitudes of change. Lastly, front tuck documentation and a survey were used to evaluate the influence of jump height on the front tuck execution perception after the training program (data analyzed through a repeated measures T test). There were no significant differences between all groups over time. However, some of the intra-group variables improved considerably. Base gymnasts IG improved their jump height in 1.06 (1.56) cm and their F-VImb in 23.75 (4.16) % with a ES of -1.19, indicating a 100% probability of a negative effect from the program since our goal was to decrease this value. Although top gymnasts IG F-VImb did not improved, they improved force values in 5.59 (5.47) N/kg with a ES of 1.29 and 90% chances of a positive effect from the program and their jump height in 0.86 (0.05) cm. Lastly, there were significant differences in the IG (P=0.013) in the front tuck execution perception analysis. We concluded that the 9-week training program was effective since even though there were significant differences in intervention groups weights and gymnasts were in a special transition period, the program managed to mitigate these negative effects by improving F-V profile mechanical variables, jump height and gymnasts specific jumping ability associated with this gymnastics discipline.
