Effect of Deep Breathing Exercise on Heart Rate Variability of Different Age Groups

Breathing affects our respiratory, cardiovascular, neurological, gastrointestinal, muscular, and psychological wellbeing. Breathing also has a general effect on our sleep, memory, and ability to concentrate and plays an important role in improving our energy level. To study the effect of deep breathing exercise on heart rate variability of different age group. Pranayama, most known as deep breathing exercises, is a compound word with Pran and Ayama. The increase in HRV may be since the reduction in breathing frequency caused by the breathing training allows the respiration to modulate the sympathetic cardiac outflow along with the vagal outflow which result in increased HRV. Compare the heart rate variability and autonomic function test between two groups before practicing deep breathing exercise. Compare the heart rate variability and autonomic function test between two groups after practicing deep breathing exercise. To find out the effect of regular practice of slow deep breathing exercise in two groups.
