Combined Effects of Alternate Nostril Breathing and Aerobic Interval Training on Blood Pressure and Heart Rate Products in Patients With Hypertension

The interventional group will perform aerobic training (stationary cycling) 3 days a week for 5 weeks, starting with 40-60% heart rate reserve (HRR) for 20-30 minutes, with thein the first week and increasing to 40-85% HRR, maintaining a target heart rate of 40-60% HRR at the lower end and 75-85% HRR at the upper end, following a 1:4 work-to-rest ratio for 30-40 minutes in subsequent weeks, with the warm up of 5 mins before the session and a cool down of 5-7 mins after every seasion. Exercise heart rate will be calculated using the Karvonen formula for the base line week and the following weeks.Following each aerobic session, they'll practice Alternate Nostril Breathing (ANB), beginning with 5 minutes in the first week and progressing to 10 minutes thereafter. ANB involves specific hand positioning and breathing techniques to promote relaxation and balance. All sessions will be supervised by a physiotherapist.

In interventional group 'A' participants will perform aerobic training for 3 days a week for 30-40 minutes a day for 5 consecutive weeks. Exercise heart rate will be calculated using the Karvonen formula. For the first base line week the aerobic session begins with a 5-minute warm-up. The primary cardiovascular component involves using a cycle ergometer (stationary cycling) at an intensity of 40-60% heart rate reserve (HRR) for 20-30 minutes. Finally, the workout will concludes with a cool-down phase lasting 5-7 minutes, allowing the heart rate to gradually return to baseline and preventing post-exercise hypotension. From the second week onwards, the aerobic training session will begin with a 5-minute warm-up to prepare the body and gradually increase heart rate. The main workout involves a cycle ergometer, maintaining a target heart rate of 40-60% HRR at the lower end and 75-85% HRR at the upper end, following a 1:4 work-to-rest ratio for 30-40 minutes. The session ends with a 5-7 min
