Exercise Prescription for Optimal Health Benefits

Introduction

Physical inactivity is now identified as the fourth leading risk factor for death globally, accounting for about 6% of the total deaths worldwide. Physical inactivity levels are rising globally, spanning all economic, educational and age strata. This has major implications for the general health of the people worldwide and for the prevalence of lifestyle diseases such as cardiovascular diseases (coronary heart disease and stroke), diabetes and cancer, and their risk factors such as raised blood pressure, raised blood sugar and overweight. Physical inactivity, i.e. lack of exercise, is estimated as the principal cause for approximately 21-25% of breast and colon cancer burden, 27% of diabetes and approximately 30% of coronary artery diseases (which can ultimately lead to heart attack). As per WHO, of the 56.9 million deaths globally in 2016, 40.5 million or 71% were due to lifestyle diseases.
