ABSTRACT
The Electrodermal activity (EDA) covers updated information on brain imaging techniques, which provide further
insight into the brain mechanisms facilitating autonomic function, emotional balance, cognitive processing etc.
The present investigation aims at assessment of electrodermal activity of the teacher trainees of yoga and physical
education that can predict the cognitive states, arousal, emotion and attention level. The EDA (unit: microsiemns)
on sixty teacher trainees (n=60; yoga trainees: 30 and physical education trainees: 30) were assessed by Biopac
machine (invented by Jean Charcot in the Russian scientific research Laboratory, validity: 0.95 and reliability:
0.98). The yoga teacher-trainees were from Kaivalyadhama yoga research institute (Lonavla, India), whereas the
physical education teacher-trainees were from Bharati Vidyapeeth University’s College of Physical Education
(Pune, India). The EDA scores of yoga trainees and physical education trainees were compared employing t-test.
The result revealed that the peripheral skin resistance of yoga group was lower and it was found higher in the
physical education group (t=12.372, p<0.01). This, in turn suggests that yoga is better than physical education in
dealing with psychophysiological relaxation that might have lowered peripheral skin resistance in attributing a
balanced state of cognitive aspects, arousal, emotion and attention level that are important for human to live a
peaceful life.
Keywords: electrodermal activities, yoga, physical education.
