Abstract(s)
O processo de preparação para a competição é uma constante preocupação
de treinadores e atletas. Neste sentido, o objectivo do presente estudo foi
avaliar a evolução na performance do sprint durante dois macrociclos de
treino em jovens nadadores de ambos os sexos. A amostra foi constituída
por doze jovens nadadores (12.25 ± 0.75 anos, 47.10 ± 6.72 kg, 1.60 ± 0.09
m). As avaliações decorreram durante vinte e três semanas de treino.
Durante este período todos os indivíduos efectuaram 133 unidades de treino
(6 unidades de treino/semana). Semanalmente, registou-se a performance
em duas repetições máximas de 25 m crol e 50 m crol, com 15 min de
intervalo. Foi utilizada a melhor performance para analisar os efeitos do
treino. Através da ANOVA de medidas repetidas foi comparada a
performance entre a primeira e as semanas seguintes. O nível de
significância foi mantido em 5%. Os principais resultados mostraram que a
performance dos nadadores do sexo masculino foi sempre superior à dos
elementos do sexo feminino e que os nadadores de ambos os sexos
apresentaram sempre evoluções positivas com a entrada do período de
preparação específica. Para além disso, nas semanas antecedentes às
competições mais importantes, verificaram-se melhorias significativas na
performance desportiva, tendo as alterações sido mais visíveis nos 50m crol.
O protocolo usado no presente estudo pode ser utilizados pelos treinadores
para programar a época desportiva e a evolução das cargas de treino.
The preparation process for competition is a big concern in both coaches and athletes. For that reason this study's main goal was to evaluate the evolution in sprint performance during two training macro cycles in agegroup swimmers of both genders. The sample was constituted by twelve age-group swimmers (12.25 ± 0.75 years old, 47.10 ± 6.72 kg, 1.60 ± 0.09 m). The evaluations took place during twenty-three weeks of training. During this period the subjects performed one hundred thirty-three training units (6 units per week). In all weeks, the performance in two trials of a 25 m and 50m front crawl all out test, with 15 min of rest, was recorded. Only the best performance was used to assess the effects of training. Using the ANOVA of repeating measures it was compared the first week's performance with those of the following ones. The significance level was set at 5%. The main results showed that the performance of male swimmers was always superior to those of female swimmers and that both genders showed positive improvements upon the start of the specific preparation period. Other than that, some significant improvements were shown in performance during the weeks prior to important competitions, especially those in 50m front crawls. The protocol used in the present study can be used by coaches to program the training season as well as the evolution of the load components.
