What factors determine the ratio of carbohydrate to fat use during exercise? Intensity of the exercise (how hard) Duration of the exercise (how long) Gender (hormones) Environmental conditions Diet/supplements 2. What happens to CHO use and fat use as exercise intensity goes up? As exercise gets harder the percentage of energy from the oxidation of CHO goes up sharply while the percentage of energy from the FAT goes down . 3. What happens to CHO use and fat use as exercise duration goes up? As exercise gets longer, the percentage of energy from FAT goes up while the percentage of energy from CHO goes down . The percentage of energy from CHO goes down as the duration gets
