Document Summary

If we are going to burn cho, the ratio is going to be close to 1. When burning fat, you need to add more o2 so the ration is going to be lower. What the graph is telling us is low intensity exercise burn mostly fat, as exercise intensity increases we"re going to burn more and more cho rer is going to become closer to 1. Basal metabolic rate (bmr)- the minimal energy needed to maintain body function (maintain 37 decrees c) Represented by a metabolic equivalent (met)= 3. 5 ml/kg/ min o2. Women have less haemoglobin (can deliver less o2- lower vo2 max) Women have lower blood volume (deliver less o2) When compared on a per kg muscle basis the differences appear. As exercise intensity increases, la production and > la use, and muscle and blood la increases. Point at which increase begins is called la threshold.
