Summary

The decreases of physiological capacities which take place with senescence include diminishing respiratory capacity as well as a reduction of heart rate variability and baroreflex sensibility. Altogether, these alterations increase elderly people's frailty and have a negative impact over quality of life. Since Yoga (Indian auto-discipline) has a wide range of respiratory exercises already investigated as components for non-pharmacological treatments for hypertension (situation in which heart rate variability is also diminished), the investigators hypothesis is that the training of respiratory exercises of Yoga may have a significant positive effect on heart rate variability and baroreflex of health elderly subjects, increasing quality of life and reducing frailty.

We included 30 health elderly subjects (both sexes, from 60 years-old onwards) divided into 2 randomized experimental groups: control (C) and respiration (R). Each group underwent an entry evaluation, followed by a 4-months training period, after which they were re-evaluated. Control consisted of 2 stretching classes per week, and respiration consisted of 2 respiratory exercises classes a week. Both groups were instructed to perform the exercises at home twice a day, and to keep a record of each session in a log sheet. Evaluations were: WHOQOL-OLD questionnaire for quality of life, 20 minutes of seated rest with heart rate, respiration and blood pressure acquired continuously for further spectral analysis.
