Document Summary
Only operate at low intensities or very high using fat and pcr systems. Indirect is your breathing air (o2 and co2) *** is the standard international unit for energy is kj. = 1. 23 kcal/min x 60 min (1 hour) and then x by 24 hours (for the whole day) *** for every l of o2 consumed, we expend 5 kcal. My trick of 1kcal/kg = 70 x 24 =1680. To solve resting vo2 of individual, must be provided weight (kg) then must know 3. 5ml and 5kcal/o2. *** when rer is 0. 7 or low, we are predominantly burning fat. *** when rer is 1. 0 or high, we are predominantly using carbohydrate. *** 0. 85 is the crossover point from fat to carbs. As it increase we are producing carbon dioxide at a given value. Several factors interact to affect lipids vs. cho. As exercise intensity gradually increases hormonal stimulation activates ffa and cho use.
