Efeitos da intensidade relativa do exercício aeróbio sobre a função cognitiva em idosas

Abstract

Objective: The purpose of present study was to investigate the acute effect of aerobic exercise in different relative intensities to the anaerobic threshold on the cognitive performance in older women . Methods: We use an experimental design with pre-tests and post-tests. Measures of alert and of executive functions were evaluated in 48 older women physically active divided in 03 experimental groups that if had exercised to the 60, 90 and 110% of OBLA (3,5 w mmol. L-1) and 01 control group. Results: We verify that the intensities of 90% and 110% of OBLA were more appropriated to the optimizing of the abilities assigned as such in the measures of executive functions as to in the simple reaction time. Conclusions: Moderate and intense exercise, realized at 90 and 110% of the anaerobic threshold improvement the cognitive performance in older women in activities that demand as much as the processing of pre-frontal regions as of the systems atentional of alert.
