Document Summary
Physical activity and energy expenditures: assessment, trends, and tracking. Heredity and hormones influence pa and performance. Why: major modifiable risk factor for chronic disease. Any bodily movement produced by skeletal muscle that results in energy expenditure: important biological implications, pa helps us reach our peaks. Important for coaches and measuring this: physiological. Metabolic equivalent for each type of pa (~3. 5 ml 02/kg/min: behavioural. Total body energy expenditure (tee: resting energy expenditure (basal metabolic rate) Basal is lowest possible point of metabolism and occurs at early morning after being asleep for a few hours. Difficult to measure: diet induced energy expenditure. Energy to digest food: activity/exercise-induced energy expenditure. Accurate with shorter period of time: adaptive energy expenditure. Cost of being active in a cold or warm environment. More during cold day because body needs to keep body warm (homeostasis) - use more calories. Adapt and when they back to lower altitude, work is easier.
