Effect of Yogic Exercises on Physiological and Antioxidant System in Man

Principal Investigator: Dr. U. S. Ray,

Objective : 1. To study the cardiovascular dynamics, neurophysiological parameters and oxygen consumption during the actualpractice of Yogic Asanas, Pranayama and Meditation.

2. To observe any improvement in antioxidant system to counter act stress induced free radicals especially after vigorous exercise.

2. To correlate the level of biomarkers of stress induced free radicals with other physiological parameters related to exercise like aerobic capacity, anaerobic capacity, anaerobic threshold or onset of blood lactate of particular concentration and heart rate dynamics.

3. To indicate most specific biomarkers suitable to study the antioxidant related changes due to yogic practices in man.Methodology: Forty soldiers from the Indian army were taken as subjects for this study. They were randomly divided in to two equal groups. One group was imparted training in various Hatha Yogic practices (Yoga Group) for 12 months (with occasional interruption for duties outside the unit or due to other exigencies). Another group was treated as control (PT Group).

All the subjects were free from any clinical disorder and had no prior experience of practicing yogic exercises. Subjects being from the army, had uniform pattern of daily routine activity schedule and used to have diet supplying 3700 Kcal (approx.) from a common mess. They gave their informed consent to participate in the study.Before the commencement of the study all the subjects returned from their annual leave of 2 months.

Yoga group was given training in selected Hatha Yogic exercises daily (six days in a week) in the morining for 12 months under the supervision of a qualified yoga instructor. Yogic practice schedule (total for one- hour period) consisted of Hatha Yogic asanas, pranayama and meditation. HathaYogic exercises were administered according to the standard procedure.

PT group performed regular exercises according to the physical training program (PT) in the army daily in the morning during this period. PT schedule (total one hour) consisted of slow running upto 4-Km (30-mn.), body flexibility exercises (10 mm.), pull up (5 mm.) and games (15 mm.).

Both the groups used to participate in various games for one hour in the afternoon. Various physiological recordings were taken at the initial stage (Initial Phase), at the 4th month (Phase 1), 7th month (Phase 2), and 11th12th month (Phase 3) of yogic training. Another group of 20 male yoga instructors (Yoga proficient, who were practicing Yoga for not less than 4 years) also participated in this study.

The Yoga proficient group performed various hatha Yogic practices in the laboratory like the yoga trainees and various physiological parameters were recorded.

Observation/ The study concluded that:
Conclusion: 1. Yogic practices along with other kinds of exercise / games may help to improve maximal oxygen uptake capacity and to reduce exercise induced perceived exertion. It may have applications in sports and general fitness program.

2. Supplementing Yogic practices with other modes of therapy may counter act the deleterious effects of oxidative stress or it may be used as prophylactic measure.

3. Sensory neural processing in the auditory evoked potential improves by yogic practice. In Bhramari and Bhastrika pranayama and Omkar meditation effects are prominent. These practices may be helpful in this respect.
