BIPN 108 Lecture Notes - Lecture 8: Stroke Volume, Indirect Calorimetry, Exercise Intensity
Document Summary
Resting metabolic rate: larger person will burn more calories. Rdee and bmr from age, wt, and height. Rdee: amount of calories burned by sitting around. 665: how regression lines fit (no physical meaning) Rdee= (factor based on weight and height) - age factor. For 20 year old male= 6. 8 x 20 = 136 cal. For 64 year old male= 6. 8 - 62 = 435 cal. Liver and brain are active organs (high demand of o2) Work done relative to the amount of energy expended to do work. Economy: measure of performance as a function of energy expended. Compare the amount of oxygen to run that speed. Efficiency is a good predictor of the race time. The more economical runners can preform better in a race. Can do more with out using as much o2. There"s some point where running becomes for efficient. Answer: can be very different between two people using the same o2 consumption.
