Effects of yoga versus walking on mood, anxiety, and brain GABA levels: A randomized controlled MRS Study
Yoga and exercise have beneficial effects on mood and anxiety. g-Aminobutyric acid (GABA)-ergic activity is reduced in mood and anxiety disorders. The practice of yoga postures is associated with increased brain GABA levels. This study addresses the question of whether changes in mood, anxiety, and GABA levels are specific to yoga or related to physical activity.
