If you are serious about getting better at something than you need to test yourself every now and again. For example, you can't claim to be a fast runner if all you do is go for runs but have never stepped up to the line in a race to measure yourself.

Not only does this approach never really tell you how good you are if never really tells you what your weak links are and what could be improved. Lactate Testing at UBCORecently I had the opportunity to go out to UBCO and do some testing. This was a test performed on a stationary bike to determine my VO2max, lactate threshold, max power and other interesting facts about what my body does when cycling. The first thing you notice when you do this test for the first time is that it's not comfortable. And I'm not talking about the physical discomfort. That comes later. Instead I'm talking about the unusual sensation of having your nose plugged and a snorkel type of mouth guard connected to tubing that can measure your expired air. In other words a computer can detect changes in the amount of oxygen and carbon dioxide in the air that is exhaled. So picture a halo type of apparatus sitting on top of your head, with a mouth guard and tubing attached to the computer beside you and a nose plug to ensure gas exchange only occurs through the mouth. And this is what is a little uncomfortable. Because once in a while in normal living we may have to take an irregular breath. Instead of the normal inhale-pause-exhale pattern of breathing sometimes we...
