When it comes to understanding the results of a lactate test, you can need a graph which shows the relationship between the test data in watt (X-axis) and the amount of lactate (mmol of lactate on Y-axis) fabricating the max heart rate for every step. Observe any points in the graph whereby the amount of circulating lactate increases appreciably, as this suggests an upper limit over which the effort has increased into a different domain of exercise (moderate, heavy, severe). It can be useful to establish the endurance properties of the athlete and training zones. Further to this, it will be useful comparing several tests at intervals to understand how the athlete performed in relation to the training and growth over that period.
