If you are looking to exercise both your body and your mind, then you may be interested in some new research conducted at the University of Illinois at Urbana-Champaign . Neha Gothe, a graduate student at Illinois who is now a professor of kinesiology at Wayne State University , led a research team to uncover data that shows a 20-minute session of hatha yoga significantly improved participants’ speed and accuracy on tests of working memory and inhibitory control. Participants showed significantly better results on these tests of retention of new information after a yoga session than after completing a moderate to vigorous aerobic exercise. Participants underwent a 20-minute progression of seated, standing, and supine yoga postures, concluding with a meditative posture and deep breathing. They also completed a 20-minute aerobic exercise where they walked or jogged on a treadmill for 20 minutes, with each subject maintaining 60 to 70 percent of her maximum heart rate throughout the workout. All subjects in the study were female undergraduates. No significant improvements in working memory or inhibitory control were found after the aerobic exercise. Researchers believe that following a yoga practice, participants were better able to focus because the breathing and meditation exercises aim to calm the mind and body, possibly translating into better mental performance beyond the yoga practice. Furthermore, meditation and breathing exercises are known to reduce anxiety and stress, which may help improve scores on some cognitive tests.
