Resumo

Nosso estudo teve como objetivo identificar os mecanismos de ação/remoção do lactato em situação de exercício exaustivo e acompanhar como a dor muscular tardia (DMT) progride em decorrência do processo de fadiga metabólica instalada. Exercícios em esteira computadorizada e cicloergômetro foram realizados durante uma aula de Bioquímica do Exercício, havendo coleta de lactato em vários tempos após o exercício. Para avaliação da DMT, utilizou-se uma escala de percepção subjetiva de DMT. Houve aumento significativo (p<0.001) em concentração de lactato imediatamente após o esforçopara os dois modelos de exercício, com retorno próximo a níveis normais em 1 hora após a exaustão. A manifestação de dor teve seu pico entre 24-72 horas após o exercício, o que levou os alunos a compreenderem que existem estratégias metabólicas distintas de recuperação após a execução de exercício exaustivo.
