Perfil de aptidão cardiorrespiratória e metabólica em bailarinos profissionais
Palavras-chave:
Capacidade Aeróbia, Balé, Respostas FisiológicasResumo
O principal objetivo deste estudo foi analisar aspectos cardiorrespiratórios e metabólicos e as alterações provocadas pelo treinamento específico de dança em umgrupo de 16 bailarinos de balé profissional, modalidade clássico, sendo 8 mulheres e 8 homens, com média de idade de 18,2 ± 3,8 anos e 26,2 ± 4,5 anos, respectivamente. Todos foram submetidos a teste máximo em esteira rolante, utilizando-se o protocolo de Bruce. Foi utilizado, na análise das respostas respiratórias e metabólicas, um sistema computadorizado Metabolic Measurement Cart da Beckman. Os seguintes resultados foram obtidos entre o grupo de balé vs o grupo-controle (masculino): VO2 max. (46 ± 4 vs 43 ± 6 mLO2. kg-1. min-1). FC máx.(194 ± 12 vs 202 ± 11 bpm); VE máx. (112 ± 16 vs 123 ± 181.min-1); VO2-LA (35 ± 4 vs 26 ± 4 mLO2.kg-1.min-1 [p < 0,01]); FC-LA (169 ± 18 vs 163 ± 15 bpm). Grupo de balé vs grupo-controle (feminino): VO2 máx. (39 ± 6 vs 35 ± 6 mLO2. kg-1-.min-1); FC máx. (197 ± 10 vs 201 ± 6 bpm); VE máx. (72 ± 9 vs 81 ± 61.min-1); VO2 -LA (26 ± 4 vs 27 ± 4 mLO2.kg-1.min-1); FC-LA (164 ± 10 vs 176 ± 17 bpm). Conclusões: 1) a rotina específica de dança parece não gerar estímulo suficiente para aprimorar a aptidão cardiorrespiratória e metabólica dos bailarinos, e 2) sugere-se condicionamento físico adicional ao treinamento de balé.
