A. Muscular-Articular Responses
Electromyographic studies have been conducted by Karam belkar et al., and by Gopal which showed the performance of Asanas involve less muscular work. Studies by Dhanaraj, R. Moses and by Gharote showed considerable changes in flexibility as a result of Yogic training programme.
B. Circulatory Responses
Ganguly and Gharote measured scores on Harvard Step Test on normal individuals before and after 8 months of Yoga training. There was found an increase of 7.6 in the test score which was statistically significant. Plethysmographic studies by Gopal and Wenger concerning finger blood flow in various practices of Hathayoga showed that the biood flow in the toe was less and blood flow in the finger was greater during the head-stand than during either the horizonal supine position or the erect standing position. S. Rao measured the forehead temperature and top of the foot temperature during head-stand and found that the forehead skin temperature increased and the skin temperature of the foot decreased during head-stand as compared to other body positions.
C, Respiratory Responses
A number of studies have found the basal respiratory rate to be lower in subjects who have practised a Yogic routine for some time. Measurements by Wenger, Datey et al., and Dhanaraj reported breath rate decreased during and after Shavasana, Increase in Breath holding time as a result of Yoga training has been reported by Bhole et al., Gopal et al., Udupa, and Moses. Increase in tidal volume has been observed by S. Rao in subjects practising Shirshasana. The head-stand tidal volume was also found greater than erect standing volume which resulted in minute ventilation. The normal movement of air whether in basal state after a regimen of Yoga practices or in non-basal states in particular yogasanas or pranayamas has been studied by Bhole et al., Udupa et al., Dhanaraj and Gopal et al. In general, the respiratory efficiency was improved as a result of Yogic training. The oxygen consumption during and after various Yogic practices was seen low. D. Endocrine Responses
Dhanaraj reported Thyroxine increase after 6 weeks of Yogic training. Udupa et al., found increased catecholamines in urine and plasma, increase in blood histaminase, increase in plasma cortisol, and decrease in acetylcholine and cholinesterase. Karambelkar et al., observed decrease in Uropepsin secretion after the training in Asanas.
