The idea that lactic acid accumulates in muscles and that massage can somehow “help remove it” has been a topic of discussion in the field of manual therapy and massage when it should be a non-issue to begin with.

There isn’t strong scientific evidence to support this specific theory. The concept of massaging out lactic acid buildup is considered somewhat outdated. Therapists who still reference this are regurgitating what they learned in massage school, more so if they learned about the “poison-laden tissue juices” from the book “The Art of Massage,” written by John Harvey Kellogg in 1895.

In “The Art of Massage,” Kellogg describes that, “By the alternate compression and relaxation (of the hands on the body), blood and lymph vessels are emptied, and fresh blood is drawn into the parts, thus… the old blood and poison-laden tissue juices are forced onward, and a new supply of pure and well-oxygenated blood is drawn in” (Kellogg, 268). Many therapists are trained that this was the antiquated term for lactic acid. It wasn’t until the mid-19th century that the French physiologist, Claude Bernard, understood and described the role of lactic acid in the human body.

Massage and lactic acid are often discussed in the context of exercise and muscle recovery. Lactic acid is a natural byproduct of anaerobic metabolism, which occurs when your muscles work vigorously without enough oxygen, thus justifying some of what Kellogg states. To find out how massage is related to lactic acid and how it can help in some situations, let’s look at the progression below.

How it Develops

During intense physical activity, the body produces lactic acid because of the breakdown of glucose for energy in the absence of sufficient oxygen. This buildup of lactic acid can contribute to muscle fatigue and discomfort.

How it Leaves the Body

Lactic acid is not a waste product but rather an energy source. The body has mechanisms to clear lactic acid from the muscles and bloodstream. It is typically removed within hours after exercise, depending on factors like individual fitness levels and the intensity of the exercise.

The Role of Massage and Lactic Acid

While massage can be beneficial for muscle recovery and reducing muscle soreness, it may not directly “get rid” of lactic acid. Instead, it can help in several ways:

• Massage can improve circulation by stimulating blood flow to the muscles, which can aid in the removal of metabolic waste products, including lactic acid.
• Massage can promote muscle relaxation and reduce muscle tension, which can alleviate soreness and discomfort associated with lactic acid buildup.
• By reducing muscle tension and improving circulation, massage can contribute to a faster recovery from strenuous exercise, allowing the body’s natural mechanisms to clear lactic acid more effectively.
• Massage can help relieve pain and discomfort associated with muscle soreness, making it easier to move and exercise again.

In summary, lactic acid naturally clears from the body over time, and massage can support this process indirectly by improving circulation, reducing muscle tension, and promoting relaxation, especially if performed following a workout. However, it’s essential to note that while massage can be a helpful part of a post-exercise recovery routine, it may not completely eliminate lactic acid, and the body’s natural processes play a significant role in its clearance.
