When we exercise, our bodies go through some amazing changes that help keep us energized and working well. Let’s explain this in a simple way.
First, when you start to exercise, your muscles need energy. This energy comes from a process called cellular respiration.
During this process, sugar from the food we eat combines with oxygen in our cells.
The reaction looks like this:
Glucose (sugar) + Oxygen → Carbon Dioxide + Water + Energy (ATP)
The energy we get from this is stored in a special molecule called ATP. This ATP helps power our muscles.
Next, when you start working out harder, your body sometimes can’t get enough oxygen to keep up. When this happens, another process takes over called anaerobic respiration.
In this process, glucose is broken down without oxygen. Though this helps produce energy, it's not as effective. It also creates lactic acid, which can make your muscles feel tired.
Also, your body makes quick changes to supply energy faster. For example, it releases adrenaline, which speeds up your heart rate and helps your body react more quickly.
Finally, after you finish exercising, your body needs to recover. The chemical reactions continue to help with this.
Lactic acid is changed back into glucose in a process called gluconeogenesis. This is also when your muscles repair and get stronger.
In short, every time you exercise, your body acts like a busy factory filled with chemical reactions. These reactions help you move and then recover afterward.
