The influence of physical activity on motor and
cognitive performance has been approved in several studies. However, it is
still unclear which functions are affected, and why. It also remains unknown
what type of physical training is best suitable. The present study focuses on
special movement aspects based on the Brain Gym® program. Four groups of
subjects (n = 64) participated in two experiments with pre-post intervention
design. In experiment 1, two groups of subjects were exposed to a sensorimotor
adaptation study design by executing center out pointing movements under
distorted visual feedback conditions with their dominant and non-dominant arm
to test for intermanual transfer (IMT) as pre- and posttest. The intervention
in both groups consisted of specified movement exercises with the right and left
extremities: participants of Experimental group executed movements crossing the
body midline and participants of Control group movements without crossing the
body midline. Results showed a decreased retention of adaptation but larger IMT
for Experimental group during posttest. We conclude that movements crossing the
body midline impede retention but enhance IMT of sensorimotor adaptation. A
potential relationship to an improvement of communication between the cerebral
hemispheres evoked by the movement exercises crossing the body midline is
rather speculative. In experiment 2, two groups were exposed to the d2-test
measuring concentration and attention and a dice-test testing for
visual-spatial abilities as pre- and posttest. The interventions were similar
to experiment 1. Results yielded no differences between groups such that
different effects of both interventions could not have been shown.
