Abstract(s)
A participação organizada em desportos de competição inicia-se cada vez mais cedo. A
literatura tem reportado uma forte associação entre as características antropométricas e
a performance na natação pura desportiva. Esta relaçãocarece de mais investigação, no
sentido de ser clarificado o seu impacto no desempenho de jovens nadadores de ambos
os géneros. Este trabalho teve como objetivo verificar o impacto das caraterísticas
antropométricas no rendimento desportivo em nadadores infantis nas provas de 50m e
400m livres. Se existiam diferenças entre géneros e/ou entre nadadores do mesmo
género mas de escalões competitivos distintos (Infantis A e Infantis B). Todos os
participantes foram analisados por suas características antropométricas (massa
corporal, altura, envergadura e posteriormente foi calculado o índice de massa corporal)
e pelo seu rendimento dos 50m e 400m. Participaram neste estudo 98 nadadores, com
idades compreendidas entre os 11 e os 13 anos (média ± desvio-padrão: 12.63 ± 0.76 anos
de idade, 1.59 ± 0.08m de altura, 47.11 ± 7.82kg de massa corporal). Todos os nadadores
pertenciam ao escalão de infantis, sendo que 48 eram do sexo feminino e 50 do sexo
masculino.. Na sessão da manhã realizaram a avaliação do rendimento na prova dos 50m
livres e durante a sessão da tarde dos 400m livres. Com base nos resultados
apresentados, podemos concluirque as características antropométricas parecem
influenciar o desempenho dos nadadores, quando comparamos os diferentes géneros e
os resultados deste estudo indicam que a eficácia dos movimentos segmentares dos
nadadores parece estar relacionada com as características antropométricas,
particularmente associadas ao comprimento dos segmentos. O estado maturacional dos
nadadores pode ter um papel preponderante nos resultados encontrados. Na
comparação entre géneros os valores de altura e peso dos nadadores do sexo masculino
sãotendencialmente mais elevados e as diferenças observadas nas provas de 50m e
400m livres, parecem estar relacionadas com a influência que as características
antropométricas exercem sobre os parâmetros biomecânicos de nado, fundamentais
para o desempenho em natação.
Organized participation in competitive sports starts earlier and earlier. The literature has reported a strong association between anthropometric characteristics and performance in pure sport swimming. This relationship needs further investigation, in order to clarify its impact on the performance of young swimmers of both genders. This work aimed to verify the impact of anthropometric characteristics on sports performance in infant swimmers in the 50m and 400m freestyle events. There were differences between genders and / or between swimmers of the same gender but at different competitive levels (Children A and Children B). All participants were analyzed for their anthropometric characteristics (body mass, height, wingspan and the body mass index was subsequently calculated) and for their performance of 50m and 400m. 98 swimmers participated in this study, aged between 11 and 13 years (mean ± standard deviation: 12.63 ± 0.76 years of age, 1.59 ± 0.08m in height, 47.11 ± 7.82kg of body mass). All swimmers belonged to the children's category, 48 of which were female and 50 male. In the morning session they performed the performance evaluation in the 50m freestyle and during the afternoon 400m freestyle. Based on the results presented, we can conclude that the anthropometric characteristics seem to influence the swimmers 'performance, when we compare the different genders and the results of this study indicate that the efficiency of the swimmers' segmental movements seems to be related to the anthropometric characteristics, particularly associated with the length of the segments. The maturational state of the swimmers can play a major role in the results found. When comparing genders, the height and weight values of male swimmers tend to be higher and the differences observed in the 50m and 400m freestyle events seem to be related to the influence that anthropometric characteristics have on the biomechanical parameters of swimming for swimming performance.
