You just might be able to talk yourself into being fitter and having more endurance.

Let’s start with the simple things first, lactic acid build up and the lactate threshold are not the same thing. The real term for what is euphemistically called lactic acid build up, what’s supposed to make it hard to push through an intense workout becuase of “the burn,” is lactic acidosis.

Lactic acid is always produced in some quantity, along with another intermediate by-product called pyruvate, in the long sequence of reactions that take place in the breakdown of glucose during exercise.

If you are not working out too intensely the lactic acid will break down and get released as energy in the presence of oxygen. If you work out really intensely, you body looks to use more glycogen for fuel because it can get a hold of it quickly but you then get a build of lactic acid, you breathe heavier to get more air to oxidize the pyruvate.

At some point, you can’t get enough oxygen in to meet the demand and lactic acid builds up, which is when you can get the proverbial burn as the concentration of acid ions goes up.

The rise in intensity of activity correlates to a rise in blood lactate levels and the lactate threshold is the point at which you move from the efficient oxygen in, burning fuel, aerobic capacity for work to the gulping for air, change in energy creation, air be damned just keep me going anaerobic capacity part of your workout.

In general terms, the concentration point for blood lactate of 4 mmol/L is used as a threshold transition point, the point at which it becomes difficult to maintain a steady heart rate and amount of power output.

As Coach Mike Tromello says in his Instagram post above, CrossFit athletes need buy Injectable Steroids online in Australia to be training their lactic acid to achieve peak performance, too. Runners need to work on their threshold in a single domain whereas CrossFit athletes need to work across multiple domains, maybe within the same workout.
