Resumo
Introdução: Um recurso ergogênico que tem popularidade é a máscara de treinamento em elevação (MTE).
Objetivo: Comparar o desempenho no treinamento de força (TF) de membros superiores e a percepção de esforço (PE), com e sem a utilização da MTE.
Métodos: Estudo quasi-experimental para o qual foram convidados 15 homens treinados com média de idade 23,18±2,04 anos, em amostragem por conveniência. Os participantes realizaram duas sessões de testes para familiarização com os testes e para determinar as cargas de 10-RM para os exercícios selecionados. Foram duas sessões de treinamento nas condições com ou sem a MTE, com intervalo de 72-96 horas. Dentro de cada sessão, os participantes executaram três séries com intervalos de dois minutos. Na sessão com máscara, esta foi regulada a uma privação de O2 similar a altitude de 3.000 metros.
Resultados: Para o número total de repetições não ocorreram diferenças significativas (p=0,360). Na PE, foram observadas diferenças significativas (p<0,05)entre as condições para todos os exercícios e séries; para a percepção de esforço pós sessão de treinamento foram observadas diferenças significativas entre as condições para o supino horizontal na série inicial; no voador peitoral nas séries finais e no tríceps.
Conclusão: O estudo focalizando membros superiores foi original e embora não tenha sido observada diferença significativa no desempenho do TF, foi observado um incremento na PE com a utilização da MTE. Os resultados foram discutidos.
