Take it to the MAX!
 
Submaximal exercise tests are sometimes performed on children by physicians in order to determine if a child has exercise-induced asthma (EIA). The physician would then base exercise recommendations on the findings. In adults, submaximal tests can be used in lieu of maximal tests such as the Bruce Treadmill Test, or Bruce Protocol, for individuals limited by pain and fatigue. Physical therapists, for example, may rely more heavily on these tests to assess their patient`s aerobic capacity. But for those who are seemingly healthy, the standard max tests can be used to interpret aerobic health.  
 
In regard to training, what is the maximum level at which one should train? It was commonly thought that it was best to train within a range below lactate threshold to avoid the accumulation of too much lactic acid. But new findings dispute the notion that lactic acid is bad for you. Muscles use carbohydrates, fats and proteins to produce energy. Most of the energy produced, however, is lost as heat. Lactic acid accumulates in muscles when intense activity is performed to make up for those times when there is not enough oxygen present to break down food into energy. When you are training at a higher intensity your body will begin to use alternate fuel sources, or make a shift from the aerobic metabolic pathway to anaerobic metabolism. During this phase, pyruvate is converted to lactate. Lactate is then converted to glucose in the liver to be used as a source of energy. 
   
The New York Times published an article some time ago that highlights research completed by George A. Brooks, a professor in the department of integrative biology at the University of California, Berkeley. Dr. Brooks believes that lactic acid is an essential fuel. During activity, working muscles need a fuel source. Training at more intense levels has been found to increase muscle mitochondria, therefore allowing the muscles to work harder and longer and, in turn, burning more lactic acid. The mitochondria will use the lactic acid as fuel. Your muscles will burn due to the acidity of lactic acid, but it will be gone from the muscles within an hour of exercise.
