Asana, pranayama, and meditation are three main techniques of yoga practiced in India over thousands of years to attain functional harmony between the body and mind. Recent studies on long-term yogic practices have shown improvements in cardiovascular functions.
The present study was conducted to ascertain if a short-term practice of pranayama and meditation had improvements in cardiovascular functions in healthy individuals with respect to age, gender, and body mass index (BMI).
This interventional study was conducted in the Department of physiology of S.N. Medical College, Bagalkot.
Fifty healthy subjects (24 males and 26 females) of 20-60 years age group, fulfilling the inclusion and exclusion criteria underwent two hours daily yoga program for 15 days taught by a certified yoga teacher. Pre and post yoga cardiovascular functions were assessed by recording pulse rate, systolic blood pressure, diastolic blood pressure, and mean blood pressure.
The parameters were analyzed by Student's t test.
There was significant reduction in resting pulse rate, systolic blood pressure, diastolic blood pressure, and mean arterial blood pressure after practicing pranayama and meditation for 15 days. The response was similar in both the genders, both the age groups, <40 yrs and >40 yrs and both the groups with BMI, <25 kg/m(2) and >25 kg/m(2).
This study showed beneficial effects of short term (15 days) regular pranayama and meditation practice on cardiovascular functions irrespective of age, gender, and BMI in normal healthy individuals.
体式、呼吸控制法和冥想是印度数千年来一直练习的三种主要瑜伽技巧,用于实现身心功能的和谐。近期关于长期瑜伽练习的研究表明,心血管功能有所改善。
本研究旨在确定短期的呼吸控制法和冥想练习对不同年龄、性别和体重指数(BMI)的健康个体的心血管功能是否有改善作用。
本干预性研究在巴加尔科特市S.N.医学院生理学系进行。
50名年龄在20至60岁之间、符合纳入和排除标准的健康受试者(24名男性和26名女性),在一名认证瑜伽教师的指导下,每天进行两小时的瑜伽课程,持续15天。通过记录脉搏率、收缩压、舒张压和平均血压来评估瑜伽前后的心血管功能。
采用学生t检验对各项参数进行分析。
进行15天的呼吸控制法和冥想练习后,静息脉搏率、收缩压、舒张压和平均动脉血压均显著降低。不同性别、年龄组(<40岁和>40岁)以及BMI组(<25kg/m²和>25kg/m²)的反应相似。
本研究表明,短期(15天)有规律地练习呼吸控制法和冥想对正常健康个体的心血管功能具有有益影响,且不受年龄、性别和BMI的影响。
