Breaks Cognition

The aim of this study was to analyze the acute effects of sitting breaks on cognition in healthy adults. Twelve sedentary healthy adults randomly completed three 3-hour conditions: 2-min isometric leg extension exercise sitting breaks at 30% of maximal voluntary contraction every 30-min; 2-min light-intensity walking sitting breaks every 30-min; Sitting without breaks. Stroop and Eriksen-Flanker tests were used to measure cognition before and after conditions. Generalized estimated equations were used to analyze cognition responses. Stroop congruent phase decreased for all conditions. There were no significant effects on Stroop incongruent phase, Stroop effect, or Eriksen-Flanker. In conclusion, walking or isometric exercise sitting breaks do not improve cognition in healthy adults.
