Recently, there is a growing interest in training effect
of working memory. It has been demonstrated that
training induced improvement in working memory was shown
in several domains such as updating, shifting, and
inhibition. Furthermore, some studies suggest transfer
effects of working memory training to cognitive
reasoning and fluid intelligence. These findings could
be attributable to improvements in general working
memory capacity by training program. To the best of our
knowledge, the plastic changes in neural networks
associated with visuospatial working memory after sports
training have been seldom studied. In the present study,
we are aimed to investigate the dynamic neural changes
in neural activation related to transfer effects of
shooting training on visuospatial working memory, using
fMRI. We used the difficult version of the judgment of
line orientation (JLO) task, which is a well-established
visuospatial task to assess angular orientation of
lines. Overall, our finding of greater activations in
fronto-parietal networks and basal ganglia during the
JLO after training suggest not only dynamic neural
changes in relation to training but also transfer
effects of training to visuospatial working memory.
Transfer effects of training to non-trained tasks might
be explained by the underlying similarities neural
networks as well as neurotransmitter. Thus, higher
activity of fronto-parietal networks in this study might
provide the basis for transfer effects of shooting
training to the JLO task and increased activity of
striatum together with increased release of dopamine
might also provide a more general mechanism that
mediates transfer effects of shooting training to the
JLO task.
