Tips for Outsmarting Your Fat Cells
An active cell is a fat-burning cell. That's why cardiovascular exercise has been touted as a fast and efficient way of losing excess body fat.
The question of the superiority of low intensity/extended duration over high intensity/short duration exercise has been Vigorously debated. Current exercise literature uses the questionable term "intensity." "High density/low density" or high/low work rate would be more suitable terms. To keep things simple, I'll be using the term "high/low density" throughout this article.
On one side of the debate you have aerobic instructors and the so-called exercise 'gurus' of our times spewing forth propaganda which claims that jumping up-and-down for 30-60 minutes to the sound of Richard Simmons is more efficient than leaving that small reservoir of perspiration on the floor and equipment following a high density work-out.
To understand the difference between the two methods we must first distinguish between the way they work.
Low Density/Long Duration (LD/LD) workouts are typically performed in the range of 50-65% of one's max heart rate ( 220-age = Max Heart Rate).
Part of the reason fat is used as a primary source of fuel during LD/LD is because fat molecules contain large quantities of energy per unit of weight.
High Density/Short Duration (HD/SD) workouts are usually performed in the range of 70-90% of one's max heart rate, so they can also be labeled as interval and anaerobic training methods. The HD/SD method derives its source of energy primarily from the phosphagen and glycolitic systems.
So, the verdict is in. It has been proven that LD/LD exercise metabolizes fat more efficiently than HD/SD exercise. On the other hand, HD/SD exercise has, over an extended period of time, shown a greater decreases in fat stores. Each method is useful depending upon individual circumstances, and factors such as time, current fitness level and the presence of potential cardiovascular problems
