Abstract
A group of apparently normal young volunteers were instructed to practice certain Asanas and Pranayama for six months in carefully controlled conditions. Before and after every three months of the course of Yoga practices these volunteers were subjected to a series of psychophysiological investigations to assess the influence of the Yoga practices ON physical health of the volunteers. The final assessment revealed a notable correction of body weight, an increase in vital capacity, reduction in the level of blood glucose and serum cholesterol besides certain evidences indicative of endocrine rehabilitation. Thus the regular practice of yoga induced notable beneficial effects on these volunteers in terms of important physiological, endocrine and metabolic functions. Simultaneously these practi¬ces. when assessed for their mental make-up revealed improvement in their performance Quotient (P. Q.), Memory Quotient (M. Q.), Health Index (H.I.), and Mental Fatigue Rate suggesting a significant improvement in their mental fitness.
