Design outcomes

Primary

MeasureTime frame
Desfecho esperado 1: Expected to find improvement in attentional inhibitory control performance, verified through the Eriksen Flanker test, with lower reaction times in milliseconds and higher response accuracy in percentage in the low glycemic load breakfast condition associated with an acute aerobic exercise session, compared to the high glycemic load breakfast and fasting conditions

Secondary

MeasureTime frame
Desfecho esperado 2: Expected to find lower blood glucose values in the incremental area under the curve at 20 and 50 minutes after ingestion of the low glycemic load breakfast compared to the high glycemic load breakfast, verified through digital puncture with the Accu-Chek Active system.
