TLDR
It is suggested that physical activity facilitates working memory by allocating more attentional resources and increasing the efficiency of evaluating the stimulus during the retrieval phase as well as engaging more Attentional resources for the early discriminative processes during the encoding phase of a working memory task.Abstract:
This study examined the effects of physical activity on working memory in older adults using both behavioral and neuroelectric measures. Older adults were assigned to either a higher or lower physical activity group, and event-related potentials were recorded during assessments of a modified Sternberg task. The results indicated that older adults in the higher physical activity group exhibited shorter response times, independent of the working memory load. Enhanced P3 and N1 amplitudes and a decreased P3 latency were observed in the higher physical activity group. These findings suggested that physical activity facilitates working memory by allocating more attentional resources and increasing the efficiency of evaluating the stimulus during the retrieval phase as well as engaging more attentional resources for the early discriminative processes during the encoding phase of a working memory task.read more

Socioeconomic differences in lack of recreational walking among older adults : the role of neighbourhood and individual factors

TL;DR: In this paper, the authors investigate socioeconomic differences in recreational walking among older adults and examine to what extent neighbourhood perceptions and individual cognitions regarding regular physical activity can explain these differences. And they find that people with a low socioeconomic status are more likely to be physically inactive than their higher status counterparts, but the mechanisms underlying this socioeconomic gradient in physical inactivity remain largely unknown.
The Effect of Physical Activity onExecutive Function: A Brief Commentaryon Definitions, Measurement Issues, andthe Current State of the Literature
Jennifer L. Etnier,Yu Kai Chang +1 more
TL;DR: Researchers in this field are encouraged to provide a clear definition of executive function, to carefully consider the relevance of published effect sizes to their own research questions, and to consider either providing a logical rationale for their selection of particular executive function measures or to use multiple measures ofExecutive function when exploring relationships between physical activity and executive function.

TL;DR: An integrated approach articulating together the classical biomechanical factors and EMG and the high-density EEG and ERP signals to allow finer mathematical analysis to optimize sport performance, such as microstates, coherency/directionality analysis and neural generators is suggested.

Beyond the “Bereitschaftspotential”: Action preparation behind cognitive functions

TL;DR: Evidences from electrophysiological and neuroimaging recording indicate that in addition to the motor areas, the prefrontal, parietal and sensory cortices may be active during action preparation to anticipate future events and calibrate responses.

TL;DR: A limited body of evidence supports a positive effect of PA on CF in young to middle-aged adults, and further research into this relationship at this age stage is warranted.
