Effect Of 12 Weeks Yoga Training And 12 Weeks Detraining on Blood Pressure Subjects with Hypertension

Abstract

Background: Hypertension, an early predictor of cardiovascular disease can be prevented by healthy lifestyle modification. Stress-induced disorders such as hypertension can be effectively managed with the holistic science of yoga. Objective: In hypertensive individuals who are receiving routine treatment, we investigated the effects of yoga training for 12 weeks and compare as well as analyze these parameters at the end of yoga training (12th week) and after 12 weeks of follow-up with hypertensive on regular treatment (non-yoga group). Materials and methods: The study involved randomly assigned 124 hypertensive subjects to either experimental or control groups where N=65, and the yoga groups where n=61 between age of 25 to 45 years were included. In both the yoga group and the control group, heart rates (HR), Systolic Blood Pressures (SBP), Diastolic Blood Pressures (DBP), Pulse Pressures (PP), Mean Arterial Pressures (MAPs), and mean arterial pressure products were recorded before, after, and during the study period. Results: The means of RPP, HR, PP, SBP, MAP and DBP of pre-post, and follow-up values of the control group were compared by RM ANOVA and also there was no significant difference were found that exists among the groups. The mean values in the test group of post-training and follow-up show a significant decrease when compared with pre-training values. There are a significant decrease in test group follow-up values and post-training compared with follow-up values of control group and post-training respectively. In test group follow-up values the significant increase is found when compared with the test group post-training. Conclusion: Yoga reduced HR, SBP, DBP, PP, MAP, and RPP in essential hypertension under resting conditions. Reduced Sympathetic Activity, Enhanced Vagal Modulation and the increased sensitivity of baroreflex might be responsible for the harmonization of autonomic cardiovascular rhythms. Detraining from yoga, on the other hand, did not result in an increase in blood pressure. In conclusion, the present study shows that regular practice in yoga is helpful in reducing the hypertension, and that deep rest keeps the body healthy.
