Lactate is constantly produced by the body.  At rest and in light exercise, the level of lactate produced is small enough that it is buffered or oxidized. As intensity increases, lactate production increases and reaches levels that are reflective of a loss of aerobic efficiency. In general, low levels of lactate are the sign of an efficient aerobic system.  High lactate levels at easy workloads are a sign of an underdeveloped aerobic system while high lactate levels at maximal workloads are a sign of a well developed anaerobic system. Over time and with correct training, lactate levels at given workloads will decrease, indicating an improvement in aerobic conditioning.   For each athlete and sport there is an optimal balance of aerobic and anaerobic qualities.

During an exercise test, blood lactate samples are taken along with other key data while you exercise at gradually increasing intensities. This data is then analyzed and an easy to use, practical prescription is provided based on your goals.  Training zones are based on heart rate, power, pace or a combination of each to suit your needs.  The test results transfer perfectly from the lab to the road enabling you to train with precision wherever you are.  Click here for an informative article from Actice.com, “Every Cyclist's Enemy: Exploring Lactic Acid.”
