Document Summary
Definition: any waking behaviour that is characterized by an energy expenditure 1. 5 metabolic equivalent (mets) while in a sitting or reclining position. The movement continuum, illustrating the different focus of sedentary physiology and exercise physiology. Mets, metabolic equivalent tasks more skills and qualifications for a job= increased likeliness of being sedentary. First evidence that inactivity is bad for you. Included in their seminal work was an ecologic study of heart disease mortality and occupational physical activity: gradual inverse relationship: sedentary living and occupation- die earlier. Compromises: bronze mineral density, vascular health. Risk factor for: obesity, some cancers. Study: sedentary time in adults and the association with diabetes, cardio-vascular disease and death. Those who spent the most time sitting were more than 2x more likely to develop diabetes. Sedentary were nearly 2x as likely of getting cardio-vascular disease. Sedentary were 1. 5x more likely to die over the course of the study. Negative effects are seen amongst all ages.
