Background: Blood pressure (BP) responses to exercise are different in individual with different body mass. In malnourished persons imbalance of autonomic nervous system is seen and this is responsible for poor cardiac health. The BP response to exercise is a useful to tool to evaluate cardiac health.
Aim and Objectives: This project was undertaken to check BP reactivity to submaximal treadmill exercise test in underweight and overweight Indian females.
Materials and Methods: A cross-sectional study was conducted in 90 healthy female participants (30 each in normal weight, underweight, and overweight categories) in age group of 1722 years after approval of Institutional Ethics Committee. Participants performed submaximal exercise on motorized treadmill machine at speed of 4 km/h for 6 min. BP and heart rate were recorded before the exercise, at 3 min of exercise and immediately after the exercise at 6 min and after the 3 min of recovery period.
Results: The resting BP was higher in overweight (112.33 ± 9.04) as compared to normal weight (104.76 ± 5.70) and underweight groups (101.5 ± 8.02). In overweight, ΔSBP was 22.46 ± 9.06 and in normal weight was 21.43 ± 8.77 and in underweight was 21.16 ± 9.33 (statistically not significant). Increased pressure response to steady exercise was seen in overweight due to elevated resting BP.
Conclusion: BP reactivity to submaximal treadmill exercise at fixed speed in female adolescents with different body mass remained same and there was no difference in BP reactivity in all three groups.
