Conclusions drawn from this systematic review suggest that physical activity and cardiorespiratory fitness are associated with P3b modulation during cognitive control and attention tasks .
Acute and chronic physical activity interventions modulate the P3b component , suggesting short- and long-term functional adaptations occurring in the brain to support cognitive processes .
These summary findings suggest physical activity and cardiorespiratory fitness are beneficial to brain function and that P3b may serve as a biomarker of covert attentional processes to better underst and the relationship of physical activity and cognition
Given accumulating evidence indicating that acute and chronic physical activity and cardiorespiratory fitness are related to modulation of the P3b-ERP component , this systematic review provides an overview of the field across the last 30 + years and discusses future directions as the field continues to develop .
Effect of strength and endurance training on cognition in older people.
The purpose of this study was to investigate the effect of moderate strength and endurance training on cognition evaluated by event-related potentials ( ERP ) in older people . Thirty-six adults , aged 60 - 85 years , were r and omly divided into three groups : sedentary control ( C ) , strength training ( ST ) , and endurance training ( ET ) . Participants performed functional fitness tests and ERP data were recorded before and after nine weeks of training . Training involved three sessions per week . Functional fitness test performance improved significantly in the ST and ET groups . The latencies of the N1 , N2 , and P2 components and the amplitudes of the N1P2 , P2N2 , and N2P3 components differed significantly between groups ( p < 0.05 ) . After training , the latencies of the P2 and N2 components at the Fz and Cz sites , decreased significantly , and the amplitudes of the N1P2 , P2N2 , and N2P3 components at the Fz site and the N1P2 and N2P3 components at the Cz site , increased significantly in the ST group compared with the ET group . After training , the latencies of N1 , N2 , and P2 components shortened significantly , and the amplitudes of the N1P2 , P2N2 , and N2P3 components increased significantly in the ST group compared with the C group . The latencies of the N2 and P2 components shortened significantly in the ET group compared with the C group , although the amplitudes of the ERP recordings did not differ significantly between groups . These data suggest that strength training might facilitate early sensory processing and cognitive functioning in older individuals . Key PointsStrength training may have facilitating effects on early information processing and cognition in older people . It is interesting that only small improvements in functional fitness affected cognitive performance . More research is needed to determine how the different exercise regimens contribute to discrete changes in CNS functioning and how such changes affect the P3 component of the ERP
