During excessive exercise, the body can accumulate lactic acid. This build-up of lactic acid occurs when the body doesn't have enough oxygen to break down glucose and glycogen for energy, leading to a temporary increase in acidity levels in the muscles and blood.

Lactic acid is produced as a byproduct of anaerobic metabolism, which is the process that provides energy to muscles when oxygen levels are low. While lactic acid can cause muscle fatigue and soreness, it is typically cleared from the body within a few hours after exercise.

It's important to note that lactic acid is not solely responsible for the muscle soreness experienced after a tough workout. Delayed onset muscle soreness (DOMS) is a separate phenomenon that occurs due to micro-tears in the muscle fibers, which can lead to inflammation and discomfort in the days following intense exercise.

To help reduce the build-up of lactic acid during exercise, it's important to maintain proper hydration, warm up before workouts, and gradually increase the intensity of your workouts to allow your body to adapt to the demands being placed on it.

By understanding how lactic acid builds up in the body during excessive exercise, you can take steps to optimize your workouts and minimize the discomfort associated with intense physical activity. Remember to listen to your body, rest when needed, and consult with a healthcare professional if you have any concerns about your exercise routine.
