Lactic Acid

What is lactic acid?

As our bodies perform strenuous exercise, we begin to breathe faster as we attempt to shuttle more oxygen to our working muscles.

The body prefers to generate most of its energy using aerobic methods (meaning with oxygen). However, some activities such as lifting heavy weights require energy production faster than what our bodies can deliver oxygen. In these cases, the working muscles generate energy anaerobically (muscles producing energy without oxygen). Therefore, the body has to produce energy via carbohydrate and ultimately Glucose (sugar). Glucose is produced through a process called Glycolysis. Glycolysis allows increased glucose breakdown-and thus energy production-to continue. However, the working muscle cells can only continue this type of anaerobic energy production at high rates for 1—3 minutes, during which time the body produces a muscular by product called Lactic Acid.

Lactic Acid increases acidity levels in the working muscle cells and gives individuals a burning sensation in the muscles as they begin to fatigue. On the surface, it seems counterproductive that a working muscle would produce something that would slow its capacity for more work. In reality, this is a natural defense mechanism for the body; it prevents permanent damage during extreme exertion by slowing the key systems needed to maintain muscle contraction. Once the body slows down, oxygen becomes available and the body recovers from the strenuous event.

Ways to avoid Lactic acid

• Remain well-hydrated at all times. 

• Workout in intervals - Mix high intensity periods with moderate intensity periods.

• Workout frequently. While it might seem counterproductive what you need to do is effectively ‘teach’ your muscles to handle lactic acid in a more effective way.
