In the last post we talked about why people may use a heart rate monitor. Click here if you missed that post. Besides the most common value people check when they use a heart rate monitor, which is calories burned there are a number of other benefits to using one. But first we should do a quick review so we're all on the same page as to what we're talking about. So here's a quick recap of some of the terms you may get thrown around on blogs and in training circles. Anaerobic Threshold - This is the intensity of exercise where energy demands cannot solely be supplied by oxygen and must be supplemented by anaerobic metabolism. Lactate Threshold - As the demands for energy produced anaerobically increase there is a lactate accumulation in the blood as well. Lactate accumulates because it is being produced faster than it can be cleared from the blood. The units for this measure may be expressed as mmol/L. VO2max - This is the highest rate of oxygen consumption at maximal intensity exercise. In other words when we are below our VO2max we can still consume more oxygen with increasing intensity. However once our VO2max has been achieved further increases with intensity will not result in increased oxygen consumption. In terms of units it is usually expressed as ml/kg/min. If I've worked with you before or you are familiar with our coaching style at Okanagan Peak Performance Inc you'll know we use a lot of analogies. So here's the analogy for lactate threshold and VO2max. Lactate Threshold is like the floor in your home. VO2max is like the ceiling. With my own training I would like to improve my lactate threshold. In other words I want to raise the floor up towards the ceiling. Let's throw...
