Understanding VO2 Max and the Altitude Challenge

When embarking on a new exercise program, there are many factors to keep in mind. One must decide on the frequency of workouts, their duration, and most importantly, their intensity. For more seasoned athletes, these factors are often broken down into much more specific areas; one such area is the consideration of VO2 max.


Understanding Hypertrophy: Why Do Muscles Get Bigger?

We know that muscle will grow when properly trained and when proper nutrients are supplied. But what biological system is responsible for this growth stimulus? Is it one or is it all of them? Is growth caused by the forces applied to the muscles through weight training , or on a more cerebral level, is resistance exercise merely a means by which we expose, through recruitment, as many muscle fibers as possible to some other stimulus responsible for growth?


Bioenergetics: Aerobic versus Anaerobic Energy Production

While we are all familiar with aerobic activity, defined in the early 1970s by Dr. Kenneth Cooper as activity during which the cardiorespiratory system provides enough oxygen for muscular effort, most of us associate anaerobic activity with that very hard effort we do during intervals. The fact is that each non-sequential muscular effort, such as turning your head, entails some measure of energy production in the absence of oxygen, qualifying it as anaerobic.
