Abstract

Background: Sedentary life has emerged as a risk factor for various negative health. Abdominal obesity plays a major role in the pathogenesis of several metabolic and cardiovascular medical problems. The myocardial blood flow can be easily measured by knowing hemodynamic predictors the heart rate and systolic blood pressure which correlate better with the myocardial oxygen consumption. Method: In this cross sectional study 70 sedentary and 70 non-sedentary (30-40 years) age matched male workers were selected. Their waist circumference, waist hip ratio, heart rate and systolic blood pressure were measured at rest. The rate pressure product was calculated to assess the myocardial blood flow. Results: The waist circumference and waist hip ratio and the systolic blood pressure were significantly (P< 0.05) lower in non-sedentary group compared to sedentary group. The heart rate and rate pressure product both showed very highly significant (P< 0.0001) reduction in non-sedentary group compared to sedentary group. Conclusion: This study shows that the sedentary workers’ myocardial oxygen consumption is much high at rest and they are more prone to ischemia due to stress and exercise.

Highlights

Prolonged sitting time is a health risk.The workplace is a key setting for prolonged sedentary time
In particular abdominal obesity, plays a major role in the pathogenesis of several metabolic and cardiovascular medical problems including type 2 diabetes, hypertension, atherosclerosis and coronary artery disease(CAD)[7,8].Waist hip ratio and waist circumference can be measured and are frequently used in large-scale epidemiologic studies to find out the health hazards caused by obesity
Another important determinant of myocardial oxygen consumption is the peak systolic blood pressure (SBP) or the peak systolic tension developed by the left ventricle[18]

Summary

Introduction

Prolonged sitting time is a health risk.The workplace is a key setting for prolonged sedentary time. Prolonged sitting time (as a specific instance of sedentary behavior), independent of physical activity, has emerged as a risk factor for various negative health. In particular abdominal obesity, plays a major role in the pathogenesis of several metabolic and cardiovascular medical problems including type 2 diabetes, hypertension, atherosclerosis and coronary artery disease(CAD)[7,8].Waist hip ratio and waist circumference can be measured and are frequently used in large-scale epidemiologic studies to find out the health hazards caused by obesity. Method: In this cross sectional study 70 sedentary and 70 non-sedentary (30-40 years) age matched male workers were selected. Their waist circumference, waist hip ratio, heart rate and systolic blood pressure were measured at rest.
