Africa-Press – Mauritius. <\/strong><\/span>As many of us hit the gym or go for a run to recover from the silly season, you might notice a bit of extra muscle soreness. This is especially true if it has been a while between workouts.<\/p>\n

A common misunderstanding is that such soreness is due to lactic acid build-up in the muscles. Research, however, shows lactic acid has nothing to do with it.<\/p>\n

The truth is far more interesting, but also a bit more complex. It\u2019s not lactic acidWe\u2019ve known for decades that lactic acid has nothing to do with muscle soreness after exercise.<\/p>\n

In fact, as one of us (Robert Andrew Robergs) has long argued, cells produce lactate, not lactic acid. This process actually opposes not causes the build-up of acid in the muscles and bloodstream.<\/p>\n

Unfortunately, historical inertia means people still use the term \u201clactic acid\u201d in relation to exercise. Lactate doesn\u2019t cause major problems for the muscles you use when you exercise.<\/p>\n

You\u2019d probably be worse off without it due to other benefits to your working muscles. Lactate isn\u2019t the reason you\u2019re sore a few days after upping your weights or exercising after a long break.<\/p>\n

So, if it\u2019s not lactic acid and it\u2019s not lactate, what is causing all that muscle soreness? Muscle pain during and after exercise When you exercise, a lot of chemical reactions occur in your muscle cells.<\/p>\n

All these chemical reactions accumulate products and by-products which cause water to enter into the cells. That causes the pressure inside and between muscle cells to increase.<\/p>\n

This pressure, combined with the movement of molecules from the muscle cells can stimulate nerve endings and cause discomfort during exercise. The pain and discomfort you sometimes feel hours to days after an unfamiliar type or amount of exercise has a different list of causes.<\/p>\n

If you exercise beyond your usual level or routine, you can cause microscopic damage to your muscles and their connections to tendons. Such damage causes the release of ions and other molecules from the muscles, causing localised swelling and stimulation of nerve endings.<\/p>\n

This is sometimes known as \u201cdelayed onset muscle soreness\u201d or DOMS. While the damage occurs during the exercise, the resulting response to the injury builds over the next one to two days (longer if the damage is severe).<\/p>\n

This can sometimes cause pain and difficulty with normal movement. The upshot Research is clear; the discomfort from delayed onset muscle soreness has nothing to do with lactate or lactic acid.<\/p>\n

The good news, though, is that your muscles adapt rapidly to the activity that would initially cause delayed onset muscle soreness. So, assuming you don\u2019t wait too long (more than roughly two weeks) before being active again, the next time you do the same activity there will be much less damage and discomfort.<\/p>\n

If you have an exercise goal (such as doing a particular hike or completing a half-marathon), ensure it is realistic and that you can work up to it by training over several months.<\/p>\n

Such training will gradually build the muscle adaptations necessary to prevent delayed onset muscle soreness. And being less wrecked by exercise makes it more enjoyable and more easy to stick to a routine or habit. Finally, remove \u201clactic acid\u201d from your exercise vocabulary. Its supposed role in muscle soreness is a myth that\u2019s hung around far too long already.<\/p>\n
