Resumen

Este estudo foi delineado para analisar a habilidade de mulheres idosas ativas de interpretar instruções de esforço destinadas a produzir o respectivo nível de esforço por meio da comparação da velocidade média de caminhada (VC), frequência cardíaca relativa (%FCreserva), percepção subjetiva do esforço (PSE) e resposta afetiva (RA) em condições específicas de exercício e instrução, durante 20 minutos de caminhada. Dezesseis mulheres idosas (66,9±5,0 anos) desempenharam individualmente seis sessões experimentais de 20 min de caminhada. Participantes receberam instruções verbais padronizadas de esforço para cada condição de caminhada. Frequência cardíaca, PSE, RA e VC foram recordadas no final dos 20 min de caminhada. A distância total caminhada foi monitorada e posteriormente a velocidade média calculada. ANOVA de medidas repetidas revelaram um efeito principal significativo para as condições de exercício nas variáveis VC, %FCreserva e PSE (p<0.001, respectivamente); comparações pareadas indicaram que essas diferenças não foram significativas entre condições espontânea, auto selecionada e prescrita esforço moderado. Em cada condição prescrita a VC, %FCreserva e PSE demonstraram um efeito progressivo e positivo nas intensidades fácil-difícil de acordo com a instrução de esforço prévia. A análise demonstrou efeito principal não significativo para as condições de exercício na variável RA (p=0.378); essas respostas permaneceram estáveis e positiva em todas as condições. Idosas ativas foram capazes de discriminar instruções verbais de esforço associadas a intensidade baixa a vigorosa que acarretou uma resposta fisiológica (FC) correspondente, PSE concorrente e uma distinta velocidade de caminhada. A RA permaneceu estável e positiva independente da condição de caminhada. Esses resultados evidenciam a aplicabilidade de instruções de esforço prévias para orientar idosas em regularem sua intensidade de caminhada.
