Study Shows Interval Training Burns More Fat
Interval training burns fat and improves fitness more quickly than constant but moderately intensive physical activity, according to research by a University of Guelph researcher.
The study by Jason Talanian, a PhD student in the Department of Human Health and Nutritional Sciences, was published in the Journal of Applied Physiology. It found that after interval training, the amount of fat burned in an hour of continuous moderate cycling increased by 36 percent and cardiovascular fitness increased by 13 percent.

Paying Your Oxygen Debt!
Why do some people breath more deeply and more rapid than others during and after exercise performance? Why does the heart rate increase? The answers to these questions lie in how much oxygen you owe your muscles and how much oxygen you possess. If the balance of your debt is greater than the balance of your reserves, the muscles must first demand these reserves as a down payment. It is only through increased respiration and accelerated heart rate that your oxygen payment in full is transacted. Let’s take a closer look at the variables that dictate supply and demand of oxygen to working, or in some cases ‘already worked’, muscles.
HDL Cholesterol
How many of you consider yourself a skeptic? I know I do. When an expert or authority makes a pronouncement that Cause A leads to Effect B, I’m a lot more likely to accept his or her ideas if this expert can explain how or why Cause A leads to Effect B or in some way describe the mechanism of its action. I have a hard time going on faith alone, especially since our playing field is littered with “experts”, many of whom disagree with each other. So when our experts tell us that aerobic exercise causes an increase in the amount of HDL cholesterol in our bloodstream, I would like to know how it happens.

Understanding why and how our body changes with the influence of diet and exercise can make all the difference in the world and one can tune and sharpen it for fast, precise results.

Exchanging Fat for Muscle
Resistance exercise obviously has more to offer than just size and strength increase. The National Federation of Professional Trainers in cooperation with the Fitness Clinic, a subsidiary research facility conducted a (2) year, limited independent research study. The study involved 40 subjects between the ages of 18 and 35. Among these subjects were resistance and aerobic athletes, general fitness enthusiasts, and overweight housewives and businessmen.
