When we get tired, our muscles go through some changes that can really affect how well we can perform. Here’s a simple breakdown of what happens:
Running Out of Energy: Our muscles use up a lot of energy quickly. This energy comes from a thing called ATP (adenosine triphosphate). When ATP runs low, our muscles don’t have enough energy.
Building Up Lactic Acid: During hard exercise, a substance called lactic acid builds up in our muscles. This is what causes that burning feeling in our muscles.
Changes in Electrolytes: Electrolytes, like potassium and calcium, help our muscles contract or move. When their levels change, it can mess with how well our muscles work.
Less Blood Flow: Our muscles need oxygen to keep going. When we’re tired, less oxygen gets to our muscles, which also slows down energy production.
All these things work together to make our muscles not work as well, leading to fatigue.
