This pilot study was carried out to determine cardiovascular effects of a single session of an integrated "silver yoga" program in senior citizens of Serene Pelican Township, Pondicherry.
Heart rate (HR) and blood pressure (BP) measurements were recorded in 124 senior citizens (75 female, 49 male) with mean age of 67.19 ± 10.61 year who attended an integrated "Silver Yoga" program at Centre for Yoga Therapy, Education and Research from August to October 2014. Participants practiced the protocol that was specially designed for senior citizens, keeping in mind their health status and physical limitations. This included simple warm-ups (jathis), breath body movement coordination practices (kriyas), static stretching postures (asanas), breathing techniques (pranayamas), relaxation and simple chanting. Non-invasive BP apparatus was used to record the HR, systolic (SP) and diastolic pressure (DP) before and after the 60 min sessions. Pulse pressure (PP), mean pressure (MP), rate-pressure product (RPP) and double product (DoP) indices were derived from the recorded parameters. Student's paired t-test was used to compare data that passed normality testing by Kolmogorov-Smirnov Test and Wilcoxon matched-pairs signed-ranks test for those that did not. P < 0.05 were accepted as indicating significant differences for pre-post comparisons.
All parameters witnessed a reduction following the single session. This was statistically more significant (P < 0. 0001) in HR, RPP and DoP while it was also significant (P < 0.01 and P < 0.05) in SP and PP, respectively. The decrease in MP just missed significance (P = 0.054) while it was not significant in DP.
There is a healthy reduction in HR, BP and derived cardiovascular indices following a single yoga session in geriatric subjects. These changes may be attributed to enhanced harmony of cardiac autonomic function as a result of coordinated breath-body work and mind-body relaxation due to an integrated "Silver Yoga" program.
本试点研究旨在确定在本地治里宁静鹈鹕镇的老年人中进行单次综合“银色瑜伽”课程对心血管系统的影响。
对124名老年人（75名女性，49名男性）进行心率（HR）和血压（BP）测量，这些老年人平均年龄为67.19±10.61岁，于2014年8月至10月在瑜伽治疗、教育与研究中心参加了综合“银色瑜伽”课程。参与者遵循专门为老年人设计的方案，同时考虑到他们的健康状况和身体限制。这包括简单的热身（jathis）、呼吸与身体运动协调练习（kriyas）、静态伸展姿势（asanas）、呼吸技巧（pranayamas）、放松和简单的唱诵。使用无创血压设备记录60分钟课程前后的HR、收缩压（SP）和舒张压（DP）。从记录的参数中得出脉压（PP）、平均压（MP）、率压积（RPP）和双乘积（DoP）指数。对于通过Kolmogorov-Smirnov检验的正态性检验的数据，使用学生配对t检验进行比较；对于未通过的，则使用Wilcoxon配对符号秩检验。前后比较中，P<0.05被认为表明存在显著差异。
单次课程后所有参数均有所降低。HR、RPP和DoP的降低在统计学上更显著（P<0.0001），而SP和PP的降低也分别具有显著性（P<0.01和P<0.05）。MP的降低刚刚未达到显著性（P=0.054），而DP的降低不显著。
老年受试者单次瑜伽课程后，HR、BP及相关心血管指数出现有益降低。这些变化可能归因于综合“银色瑜伽”课程中协调的呼吸-身体练习和身心放松，从而增强了心脏自主功能的协调性。
