The article How to reduce lactic acid build up in your muscles during exercise - and why it is important by Ava English describes the process of lactic acid buildup and how it affects us when we are exercising. Lactic acid is a byproduct of high intensity exercise which creates a burning sensation in the muscles that are being worked. A buildup of lactic acid occurs when your muscles require more oxygen than you can breathe in. This is called anaerobic respiration. Lactic acid is a byproduct of anaerobic respiration. English also says, "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." Since lactic acid proves to be a problem that can cause a burning sensation and it is very likely to occur during intense exercise, how to we remedy it? English covers this with two points: rest or reduction of exercise intensity. By choosing to rest, one is letting their body take in oxygen that is to be supplied to the muscles without maintaining a usage of oxygen through intense exercise. The other way, choosing to reduce the exercise intensity, will help prevent the buildup of lactic acid because it is allowing your muscles to use the amount of oxygen that it is taken in through respiration. Exercising this way is called aerobic respiration, where the oxygen required for exercise is the amount of oxygen being taken in through respiration.
Another topic that English covers is the difference between lactic acid and delayed onset muscle soreness. Delayed onset muscle soreness, or DOMS, is the muscle pain that occurs one to three days after strenuous exercise. According to English, "The soreness you feel is inflammation caused by normal damage to your muscle fibers during a hard workout." The main differences between lactic acid build-up and DOMS is the symptoms and the treatment. Lactic acid build-up will occur towards the middle or end of your workout and can be treated by decreasing workout intensity or resting. On the contrary, DOMS will generally occur within 24 to 72 hours after exercise and can be treated by foam rolling, massage, or applying ice/heat to the affected area.
