Defined Fitness Wexford Tip of the Week #45

This past month MSN released at study headlined "Jogging Beats Weight Lifting for Losing Belly Fat: Study" the findings claimed that 196 participants were placed in one of two groups jogging or weight lifting and participants did this for 8 months. The jogging group did 12 miles per week at 80% heart rate. The weight training group did 3 sets of 8-12 reps 3 times per week (they did not mention how many exercises or what type of exercise, but we dug deeper and found the actually research and what was used!) The results found that the jogging group burned 67% more calories than the resistance training group.

But, here's the rest of the story!

1. This was a machine based weight training program that placed participants seated on a machine doing isolated single-joint exercises. Not what we espouse here at Defined Fitness, which is a multi-joint total body approach and nothing is done seated.

2. It's not because of resistance training that participants showed no results in 8 months, it's a sign that a machine based program does not work.

3. The jogging group burned 67% more calories than the resistance training group. What has been overlooked by most in the industry here, researchers and trainers alike, is that current caloric expenditure is only measured from the standpoint of the aerobic system, not from the standpoint of the anaerobic system, which is the system used when weight lifting. Basically, it's like comparing apples to oranges.

In 2005 research Christopher Scott published his study, Misconceptions about Aerobic and Anaerobic  Expenditure. J Int Soc Sports Nutr. 2005 Dec 9;2:32-7. He found that when caloric expenditure was measured using the anaerobic system it was much, much greater than the calorie burn measured by using the aerobic system. If both energy systems caloric burn was measured for each activity the jogging group would be no where near 67% higher than the resistance training group. In addition the jogging group was doing pretty intense exercise (12 miles at 80% heart rate), much more intense than the machine based weight training program. Intensity has always been shown to correlate with fat loss.

In addition, EPOC (the number of calories burned after exercise) was not measured either. 2002 research has shown that after a workout similar to what we do here at Defined Fitness resulted in an elevated metabolism for 38 hours. And no elevated rate after was found after the completion of aerobic exercise. So after resistance training participants continued to burn calories from their workout for the next day and a half, while after completing aerobic exercise the calories burned from exercise stopped. Also, a 1999 study found that this type of specific resistance training program increased fat loss by 35% over diet and aerobic training.

The take away from the MSN study is that hard intense cardio at 80% max is better than easy, poorly designed machine based resistance training.

However, that is not what we do here at Defined Fitness. Our clients are put on a challenging program that involves total body movements with heavy weight and appropriate, but limited rest. In our current files we have close to 100 studies showing resistance training to be more effective than aerobic training. This is the first study to show the opposite.

What Our Members Say!!
"Before coming to Defined Fitness I had tried other gyms, but never received much attention or direction from their personal trainers. When I first joined Defined Fitness I was skeptical because of my past experiences. However, after working with one of the fitness coaches at Defined Fitness I've lost 15 pounds and can finally do push-ups! Also, I had never worked up a sweat before when working out and honestly believed that I just couldn't sweat. Thanks!" - Maggie L.
