Background: Physical activity is an important part of daily life, which emphasize the importance of a healthy motive among people of various cultures and traditions. Physical inactivity and a sedentary lifestyle contribute significantly to cardiovascular risk. Maintaining cardiorespiratory fitness through physical activity necessitates working out in the recommended target heart rate zones. In this study, we investigated the significance of target heart rate zones during aerobic exercise using wearable fitness devices among both active and sedentary individuals. The primary goal of this study is to use wearable fitness devices to monitor target heart rate zones and to improve aerobic exercise level in order to promote cardiac health.

Method: In this study, Participants were divided based on Global Physical Activity Questionnaire (GPAQ) Proposed by World Health organization (WHO) into active and sedentary individuals. In accordance with the American Heart association (AHA) and American college of sports medicine (ACSM) recommendation, all the participants were asked to do aerobic physical activity for at least 30 minutes five days a week using wearable fitness device and aerobic exercises were monitored. Parameters like BMI, Rating of perceived index (RPE), resting heart rate, Average heart rate, Maximum heart rate and Target heart rate zones were observed and assessed.

Results: Participants in active group (0.69±0.12) achieved recommended target heart rate zones whereas in sedentary group (0.54±0.1) could not achieve with a P-Value of <0.001. Statistically significant results were also seen in average heart rate during exercise among active (133±24) bpm and sedentary (102±19) bpm. The maximum heart rate during exercise in active (160±21) bpm and sedentary (131±17) bpm was observed.

Conclusion: Sedentary people can improve their aerobic exercise by monitoring target heart rate zones. These individuals were unable to reach their target heart rate zones, but this wearable technology will assist them in significantly improving better cardiac health.
