Concussions are a common issue in sports, and they can have lasting effects on an athlete's performance.  This is especially true when it comes to balance and coordination.  Researchers wanted to see how a history of concussions affects an athlete's ability to maintain balance while performing upper limb movements.

        They looked at two groups of male athletes.  One group had never had a concussion, and the other group had experienced two or more concussions.  The athletes were asked to reach for visual targets with their dominant hand while standing.  Sometimes, their arm would be perturbed, or pushed off course, and sometimes they had to press a button with their non-dominant hand at the same time.  This was to see how well they could multitask while maintaining their balance.

        The athletes with a history of concussions showed larger movements in their center of pressure, which is a measure of balance.  This means that their balance was more affected by the perturbations.  When the athletes had to perform two tasks at once, both groups showed signs of increased cognitive processing and divided attention.  This was shown by slower reaction times and changes in hand movement.  It seems that athletes with a history of concussions may have worse balance control.  This could be due to issues with sensorimotor processing or increased neural time delays, which can lead to a reduction in motor activation.

        When the athletes had to perform two tasks at once, their balance control was maintained, but their upper limb performance suffered.  This suggests that their attentional resources were focused on maintaining balance, rather than on performing the upper limb task.  This is an important finding, as it shows that athletes with a history of concussions may need to be more careful when performing tasks that require both balance and upper limb movement.

        Concussions can have serious effects on an athlete's performance, and it's important for coaches and trainers to be aware of these effects.  By understanding how concussions affect balance and coordination, they can help athletes to train more effectively and safely.  It's also important for athletes to be aware of the effects of concussions, so that they can take steps to protect themselves and their teammates.  Concussions are a serious issue in sports, and it's important for everyone involved to take them seriously.
