Impact of Yoga as an Add-On Intervention on Neurocognitive Functions Among Adult Athletes: A Pilot Study.

Abstract

Athletes are vulnerable to musculoskeletal injuries and psychiatric conditions. Previous studies have reported the benefits of yoga on cognitive functions among healthy children, adults, and the elderly. This pilot study aimed to test the neurocognitive functions among athletes with/without yoga intervention. A non-randomized, two-armed parallel-group, single-blind comparative trial was used. The participants were grouped into (i) yoga with sports activity (YSA, n = 15) and (ii) sports activity alone (SA, n = 14). The subjects were assessed at the baseline and after a one-month intervention using digit span forward (DSF), digit span backward (DSB), Trail Making Test(TMT) A & B, and Rey Auditory Verbal Learning Test (RAVLT).A comprehensive one-hour yoga training three days a week for two months constitutes selected asanas (postures), pranayama (breathing techniques), relaxation techniques, and meditation techniques. The control group constitutes the routine sports activity for the same period. A paired sample t-test showed a significant improvement in cognitive performance on TMTA & B duration and RAVLT total score in the YSA group comparedwith the SA group. However, asignificant trend was observed for DSF, DSB, and RAVLT immediate recall. Independent sample t-test (pre-post change scores) showed no significant group difference in cognitive performance, except there was a significant trend observed related to DSF (p = 0.053) and RAVLT distraction (p = 0.09), where the yoga group showed better performance in cognitive functions. The results suggest that yoga may be integrated with sports to enhance neurocognitive functions.
