PHTY203 Lecture Notes - Lecture 2: Resting Metabolic Rate, Weight-Bearing, Exercise Intensity
Document Summary
Define the following terms: metabolism, the chemical reactions that occur in the body in order to produce energy and maintain homeostasis. Involves the synthesis, breakdown, and maintenance of substances: energy expenditure, the cost of all metabolic processes in the body, thermic effect of food, energy expended during the digestion, transport, and absorption of exogenous. In healthy individuals makes only a small contribution to total daily energy expenditure: exercise augments diet-induced thermogenesis do encourage calorific expenditure for weight control, climate, rmr influenced by environment - warmer climate - higher rmr. Exercise in warmer environment: increased metabolic load related to extra activity for thermoregulation. Is also related to body fat and clothing note shivering increases rmr: exercise in extreme cold - increased metabolic load, pregnancy, likely to be related to increased weight bearing loads, body mass: Terrain and walking surface ie sand 2 time more than hard surface.
