From Wikipedia, the free encyclopedia. Climate ethics is an area of research that focuses on the ethical dimensions of climate change (also known as global warming), and concepts such as climate justice.
After you do a vigorous or long workout, your blood and muscle glucose will be much lower than before you started. Low glucose stores signal the body to burn fat preferentially. So after hard exercise that uses a lot of glucose, the body switches to burning fat. That's why all energy expenditure is important, not just fat burning during exercise.
Gas Exchange During Exercise. During exercise, your body needs more energy, which means your tissues consume more oxygen than they do at rest. Consuming more oxygen means you will also produce more carbon dioxide because your metabolic rate is elevated. The ratio of carbon dioxide produced per oxygen consumed also increases during exercise because a shift from fat to carbohydrate utilization takes place. At the most challenging work rates, you burn carbohydrates exclusively and produce 1.0 liter of carbon dioxide for every liter of oxygen you consume.
