Objective: To investigate the effect of exercise on improving heart rate variability, which is a parameter to assesÂ’ autonomic control?.
Methodology: It was a control trial conducted at Islamic International Medical College and CMH Kharian Medical College from May to December 2018. Participants were labelled as stressed and controls on the basis of DASS questionnaire Performa. Study included 40 stressed participants for recording of heart rate variability. Participants were subjected to cycling exercise, five days a week for a period of six consecutive weeks after which heart rate variability was recorded again.
Results: There was significant reduction in LFms2 and LFnu and LF/HF post exercise (p=0.004, 0.001, and 0.001, respectively). HFnu after exercise significantly increased in stressed subjects (p
Key words: Stress, heart rate variability, frequency domain methods, low vs high frequency, low frequency to high frequency ratio, moderate exercise.
