Lactic acid builds up after you work out hard. Your muscles are exhausted and need to repair themselves. Check out the related link to find out tips on how to reduce muscle soreness after prolonged use.
The build up of lactic acid causes muscle to become sore. Remember: you do not grow in the gym. What you should do in the gym is actually tear down muscular fibers by training hard. If you eat and recover well from training, that is when muscular repair and growth occurs.
The rule to ensure systemic as well as localized recover is to wait 24 or 48 hours after all DOMS (delayed onset muscular soreness) has disappeared before training again. Do not worry about DOMS. Instead, think of it as a sign of progress!
It Builds up when you exersize and muscle cant get enough oxygen. its another way of creating energy.
the lactic acid builds up
because you are tearing them when you work them out.
When muscles are over-exerted, the muscle cells carry out anaerobic respiration to compensate for the oxygen deficit. Lactic acid produced as a result of this causes muscles to become sore or develop cramps.
Lactic acid. This chemical results in the ache from exercise as it builds up inside muscles, and is a component of yoghurt as it is produced from lactose.
Anger causes the release of hormonal signals that cause the muscles to tense up. When the muscles are tensed for too long, this causes fatigue and sore muscles.
Joint pains can be caused by starting a new workout routine. If your body is not used to exercising a lot and then you start and exercise program, you joints and muscles may become stiff and sore.
Lactic Acid forms in the muscles as a metabolic by-product of intense muscle use. The resultant lactic acid (CO2 Buildup) in the muscle causes a delayed onset muscle stiffness/soreness.
The muscles in the posterior can become sore due to overexertion. For instance, running or walking long distances can cause a great deal of soreness in the legs and buttocks.
Mumps
Lactic acid created during a process of "lactic acid fermentation."
your muscles will get smaller and you will be sore all the time, and your immune system will become weaker.
