Document Summary
Talking about ee and pa because it"s a major modifiable risk factor for chronic. Any bodily movement produced by skeletal muscle that results in energy expenditure: important biological implication allows us to reach our peak/optimum level. Assessment components include: mechanical force/velocity/acceleration, physiological o2 uptake/metabolic energy/mets (metabolic equivalents, behavioural - type/environmental and social influence (opportunity) Total body energy expenditures (tee: made up of the resting energy expenditure (bmr), diet-induced energy expenditure and activity/exercise induced ee, adaptive to climatic stress (exposure to heat/cold/altitude) More ee in cold environment: can only measure accurately for short periods of time, eee is only estimated. Diee: energy required for mechanical and chemical processing, absorption and storage. Increase ree by 10-15: measured 3-4 hours postprandial (post-meal) Eee: most variable component of total ee, results in a short term increase 10 to 20 x the ree, over 24 hours, it may be up to 50% of the total ee, met.
