Preventing exercise-induced hyperlactatemia. Share on Pinterest Drinking plenty of water can help the body to break down excess lactic acid.
Lactic acid and exercise. Nonexercise-induced lactic acidosis. Share on Pinterest A person with lactic acidosis may experience pain in the belly, nausea, and sweet smelling breath. Exposure to air pollutants may amplify risk for depression in healthy individuals. Costs associated with obesity may account for 3. Related Coverage. Should you do cardio or lift weights? What is the ideal heart rate when running? This happens during longer and more intense workouts because lactic acid is produced at a faster rate than your body is able to remove it.
As soon as you rest, or decrease your exercise intensity, your lactic acid levels will return to normal and the burning sensation should go away. However, some people may be at risk for lactic acidosis, a condition that causes lactic acid to build-up in the bloodstream.
Most lactic acid moves through the bloodstream to the liver where it is broken down — but people with liver problems are not able to do this as effectively when exercising. Symptoms of lactic acidosis include:. Other groups of people that are at risk for lactic acidosis include those with conditions that cause low blood pressure and too little oxygen flow to tissues.
These include:. Lactic acid is often blamed for soreness after a workout, when in fact, this is caused by delayed onset muscle soreness — also known as DOMS. DOMS refers to muscle pain that develops one to three days after strenuous exercise. The soreness you feel is inflammation caused by normal damage to your muscle fibers during a hard workout.
Lactic acid production is not unhealthy, but it can be uncomfortable. Here are some tips to help you prevent lactic acid buildup and reduce discomfort during a workout. Take more breaks. But the slide shows that after heavy exercise the lactic acid levels are back down to baseline within about an hour. It is true that it goes down faster with either walking or jogging, but it also goes down pretty fast if you do nothing.
The other thing to remember that in events lasting hours, such as most stages of the Tour de France, it is unlikely that the muscle are producing a whole lot of lactic acid after four or five hours of cycling.
George Brooks at Cal. He and other colleagues have also shown that the lactate part of lactic acid can actually be a fuel for muscles and the heart and that the acid part of lactic acid is not the cause of fatigue. It might be a contributor, but fatigue is multi-dimensional and caused by a number of factors. Here is a great summary by Dr.
Bruce Gladden :. Since the s, a 'lactate revolution' has occurred…… It now appears that increased lactate production and concentration as a result of anoxia or dysoxia hypoxia are often the exception rather than the rule. Lactic acidosis is being re-evaluated as a factor in muscle fatigue…. Blood lactic acid concentration and subjective sensations of muscular soreness were assessed at intervals for 72 hours after the runs.
Lactic acid concentration was significantly increased during running on the level, but subjects experienced no significant post exercise muscular soreness. 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. These eccentric contractions have been shown to result in more muscle cell damage than is seen with typical concentric contractions, in which a muscle successfully shortens during contraction against a load.
Thus, exercises that involve many eccentric contractions, such as downhill running, will result in the most severe DOMS, even without any noticeable burning sensations in the muscles during the event. Given that delayed-onset muscle soreness in response to extreme exercise is so common, exercise physiologists are actively researching the potential role for anti-inflammatory drugs and other supplements in the prevention and treatment of such muscle soreness, but no conclusive recommendations are currently available.
Although anti-inflammatory drugs do appear to reduce the muscle soreness—a good thing—they may slow the ability of the muscle to repair the damage, which may have negative consequences for muscle function in the weeks following the strenuous event. Already a subscriber?
