I have a question regarding lactic acid buildup in muscles?

It goes away: They say "pain is just weakness leaving the body". But it's really lactic acidosis building up in the muscles. This occurs as part of the normal metabolism of glucose by your muscle in the absence of oxygen (called anaerobic metabolism). The Lactic Acid clears from the muscles (and your body) with rest, plenty of fluids and appropriate nutrition. ...Read more

Muscle (Definition)

It is a body tissue that has the ability to contract. It shortens and generates force. It relaxes and returns to its original length. Muscles move joints, stabilize the body, move air and food through the organs, act as valves for bladder, bowel and other organs. They control movement of the eyes. They help us express ourselves by changing the shape of our ...Read more

Can you explain to me how athletes can feel less pain of lactic acid, I mean how in detail their muscle adapts to it?

Can you explain to me how athletes can feel less pain of lactic acid, I mean how in detail their muscle adapts to it?

Increased blood flow: Lactic acid comes from anaerobic metabolism (metabolism in the absence of oxygen). Over time, athletes increase their blood supply to muscles thus delivering more oxygen to muscle the decreasing the amount of Lactic Acid build up. Also, the body rids itself of Lactic Acid via the lungs. As they train, athletes become more efficient at "breathing out" lactic acid. ...Read more

Is there any effects of ssri on lactic acid build up in the muscle during swimming practice?

No: Lactic acid is a byproduct of anaerobic exercise, that is, vigorous exercise that outpaces the body's ability to supply oxygen to the tissues. It's not dangerous but can be painful; it helps to work the muscles to a gradual stop instead of stopping suddenly. To the best of my knowledge, ssris have no effect on this process. ...Read more

Contraction (Definition)
