Effect of Yoga on Pulse rate and Oxygen Saturation: Analysis of Psychophysiological Parameters
Palavras-chave:Pulse oximeter, pulse rate, oxygen saturation, Yoga, Asana, psychophysiological Parameters.
Introduction Pranayamic breathing is a process of continuous, regularity of inhalation, holding of breath and exhalation. All venous blood is converted to oxygenated blood . However, does deep breathing in which oxygen is inhaled in large amounts increase oxygen saturation or does the saturation decrease due to anaerobic metabolism associated with yoga? Does the psycho-physiological parameters of stress index, power, vegetative index & regulation, neurohumoral regulation, psycho-emotional state, energy resources, complex index, harmonization, biological age and energies in the spine get affected a"er a yogic intervention? Methods 52 subjects of age range from 15-70 years performed “Yoga module for the Healthy Heart” for 45 minutes at AYUSH, AIIMS, Bhopal. Pulse rate and oxygen saturation was measured by pulse oximeter a"er initial rest of ten minutes and a"er 45 minutes of yoga. A pilot study was conducted using the DINAMIKA HRV for ten yogic practitioner who were regular in their practice for last 10-15 years. #eir psycho-physiological parameters were measured before and a"er their yogicroutine of 35 to 40 minutes by Dinamika Heart rate variability (HRV) instrument. Results #e readings were analysed using paired t test. #epulse rate dropped from 81.98 ± 13.05 to is 74.98 ± 11.64 at p value <0.0001 indicating a shi" towards parasympathetic dominance. Oxygen saturation dropped from 97.40 +/- 1.11 to 97.21 +/- 1.30 at p value of 0.2736, indicating a shi" to anaerobic metabolism during yoga practice #e psychophysiological parameters of pulse rate, stress index, power, vegetative index & regulation, neurohumoral regulation, psycho-emotional state, energy resources, complex index, harmonization, biological age and energies in the spine were statistically significant post yogic intervention. By the power of will the yogic practitioner is able to draw cosmic energy in the spine which helps to renew it. #e mind is able to overcome strong physical distractions, the body is relaxed and calm. Relaxation is achieved by stilling of muscles, calming and slowing down the activity of heart, respiration and circulation.
