Good question. More oxygenated blood, more blood, circulates more blood. Lymph cleans the toxins out, it stimulates the production of ATP, increases cell metabolism, increased activity of the mitochondria.
Exercise impacts cellular respiration by increasing the demand for energy in the body. During exercise, cells require more oxygen to produce energy through aerobic respiration. This process involves breaking down glucose and other nutrients to create ATP, the energy currency of cells. As a result, exercise can enhance the efficiency of cellular respiration and improve overall energy production in the body.
Exercise requires energy, and some of that energy comes from stored body fat. Regular exercise then, combined with a sensible diet, will lead to reduced body fat.
mechanical energy
Your body consumes energy all day and all night, whether you exercise or not, until you are dead. When you exercise, and for a short while thereafter, your body burns more energy than normal.
Carbohydrates give you lots of energy to do exercise.
Oxygen and energy.
During exercise, your body uses energy. This process requires oxygen. So, if you exercise you pant, or breathe harder, in order for your body to draw in more oxygen.
As you exercise your body uses stored fuel and turn it into energy to power mechanical movement. In this process, energy in the form of heat is released in to the surroundings. Therefore this is an exothermic process.
The Human body needs to overcome gravity, and other external forces in order to move. In order to do this work, every cell involved must produce energy. This energy is produced by converting molecules in the body to other substances though the breaking of high energy bonds. In order to create the high energy bonds in the first place each cell must use what is called the Electron transport chain. This requires Oxygen, and so as your body needs to create energy at a faster rate as you use it up during exercise you must breath quicker in order to meet the demand
The body primarily utilizes fat for energy during periods of low intensity exercise or when fasting.
by doing works or tasks it is using energy by moving your body exercise works
It gives off thermal energy.
