Document Summary

This lecture focuses on total daily energy expenditure(tdee) and how physical activity affects it. Firstly, bmr (basal metabolic rate), which is the energy needed to maintain the body at rest must be understood as an important component of tdee. The thermic effect of food (tef) is another component influencing tdee, and it is the energy required to digest food. The physical activity component however, has the most variability and is influenced by the fitt principle (frequency, intensity, time, and type). These principles can be used to make recommendations to populations. Intensities of movement are defined by mets: sedentary: 0-1. 5, light pa: 1. 5-3, moderate pa: 3-6. 5, vigorous pa: 6-7. The movement behavior intensity continuum consists of sleep duration, sedentary time, physical activity, and are three co-dependent behaviors that fall on the movement intensity continuum. There exist several guidelines for many populations and comprise of pa guidelines and 24-hour movement behavior guidelines.
