Relação entre Percepção e Ação durante os Movimentos de Sentar e Levantar em Indivíduos Idosos
Palavras-chave:
Psicofísica, Controle motor, Idosos, Sentar, LevantarResumo
A proposta deste estudo foi analisar o efeito do envelhecimento nos aspectos perceptivos e motores envolvidos com as ações de sentar e levantar de uma cadeira. Indivíduos jovens e idosos foram filmados enquanto sentavam/levantavam de uma cadeira em sete alturas diferentes do assento. Eles julgaram a dificuldade/facilidade encontrada para sentar e levantar em cada altura do assento. Os idosos exibiram mudanças na estratégia de controle usada para sentar na altura mais baixa do assento e superestimaram o nível de dificuldade/facilidade para realizar as tarefas de sentar e levantar. Em síntese, a percepção de execução fácil da tarefa de sentar pelos idosos não concorda com o grau de dificuldade exibido no desempenho motor na altura mais baixa do assento.
