Contrary to popular opinion, lactate or, as it is often called, lactic acid buildup is not responsible for the muscle soreness felt in the days following strenuous exercise.
Rather, the production of lactate and other metabolites during extreme exertion results in the burning sensation often felt in active muscles, though which exact metabolites are involved remains unclear. This often painful sensation also gets us to stop overworking the body, thus forcing a recovery period in which the body clears the lactate and other metabolites. Researchers who have examined lactate levels right after exercise found little correlation with the level of muscle soreness felt a few days later.
This delayed-onset muscle soreness, or DOMS as it is called by exercise physiologists, is characterized by sometimes severe muscle tenderness as well as loss of strength and range of motion, usually reaching a peak 24 to 72 hours after the extreme exercise event. Though the precise cause of DOMS is still unknown, most research points to actual muscle cell damage and an elevated release of various metabolites into the tissue surrounding the muscle cells. These responses to extreme exercise result in an inflammatory-repair response, leading to swelling and soreness that peaks a day or two after the event and resolves a few days later, depending on the severity of the damage.
In fact, the type of muscle contraction appears to be a key factor in the development of DOMS. When a muscle lengthens against a load—imagine your flexed arms attempting to catch a thousand pound weight—the muscle contraction is said to be eccentric.
In other words, the muscle is actively contracting, attempting to shorten its length, but it is failing. The result is that sort of cherubic glow you can only achieve after a facial. Lactic acid doesn't have to be reserved for the skin on your face and body. It's also excellent for the scalp, where it may exfoliate flakiness and strengthen the hair follicle. We love this particular shampoo for its invigorating scent and powerful clean.
Touted as "the Hollywood two-minute facial," this pore-unclogging treatment uses lactic acid and fruit enzymes to vacuum out congestion, leaving behind a smooth, bright complexion you'd think were only achievable by the hands of an esthetician. For those who aren't familiar, squalane is a super-nourishing and incredibly clean oil that Biossance works into all their products. This is particularly helpful when paired with exfoliators, which take a bit of a toll on the skin.

Keeping the body hydrated during exercise gives it the best chance of breaking down any excess lactic acid. People can ensure they stay hydrated by drinking plenty of water. The body starts to produce lactic acid when it is low in the oxygen necessary to convert glucose into energy. Breathing deeply will help deliver oxygen to the muscles, thereby slowing the production of lactic acid. When a person feels the effects of lactic acid buildup, they can slow down and reduce the intensity of their workout.
This will allow blood oxygen levels to recover. Lightly stretching the muscles after a workout can help to alleviate any burning sensations or cramps that lactic acid buildup may cause. In most cases, lactic acid buildup is a harmless response to strenuous exercise and will go away on its own. Once the body has used the resulting lactate for energy, the liver breaks down any excess in the blood.
For a long time, experts thought that lactic acid was responsible for delayed onset muscle soreness DOMS following exercise. However, experts no longer believe this is the case. Instead, they now say that DOMS pain and stiffness is the result of microscopic damage to muscle fibers. Certain health conditions can lower blood oxygen levels, resulting in increased lactate production. These conditions include:. This can result in high blood lactate levels, which doctors call hyperlactatemia. In some cases, hyperlactatemia can progress to lactic acidosis.
This alteration can result in severe health complications. Lactic acidosis is also a rare side effect of some HIV medications. Weight Loss. Type keyword s to search. Today's Top Stories.
