Effect of 12 Weeks of Yogic Training on Neurocognitive Variables: A Quasi-Experimental Study.

Abstract

Background:Neurocognitive abilities are the brain-mind skills needed to initiate any task from the simplest to the most complex, decreases with advancing age. Attention, alertness, and memory are the basic neurocognitive functions most affected by age. There are potential benefits of yoga on neurocognitive functions because this ancient Indian technique positively nurtures the mind-body systems.Aim of the Study:The present study was aimed to evaluate the effect of 12 weeks of yogic training on neurocognitive abilities in a middle-aged group.Methods:A total of 86 volunteers (46 male and 40 females, age group of 35–55 years), with no prior experience of yoga were participated in this study. Five male and 4 female participants were excluded from the study. All participants divided into yoga training group (male = 21 and female = 18) and control group (male = 20 and female = 18). The yoga training group underwent yoga practices, including kriya, surya namaskar, asana, pranayama, and dhyana daily in the morning, for 6 days/week, for 12 weeks. Standing height, body weight, body mass index, visual reaction time (RT), auditory RT (attention and alertness), and short-term memory were assessed day 1 (pre), 6th week (mid), and 12th weeks (post) of intervention.Results:Repeated-measures analysis of variance showed that a statistically significant increased (P < 0.05) in attention-alertness and short-term memory after 12 weeks of yogic practices.Conclusion:Integrated approach of yogic intervention may have promising effect on neurocognitive abilities that concomitantly promote successful aging.
