Reduced glutamine levels were previously found in the prefrontal white matter of female varsity rugby athletes after a season of play potentially induced by exercise or caused by sub-concussive hits. The current study examined a group of non-contact female varsity athletes and found no changes in glutamine levels, ruling out an exercise effect. Additionally, differences in absolute N-acetyl aspartate, creatine, myo-inositol, glutamate and glutamine were found between rugby players and non-contact athletes. With the future addition of a sedentary group, these data have the potential to elucidate the beneficial and negative effects of exercise and contact play.
