Aerobic and Resistance Exercise

January 27, 2009 Written by JP       [Font too small?]

Do you exercise? Are you planning on starting an exercise program? In either case, you’ll want to exercise in the most efficient way possible. In today’s blog, I’ll provide some new research that may help you construct a more effective exercise regime.

Use It to Lose It

A report was just released in the Archives of Internal Medicine that attempted to determine the best form(s) of exercise for sedentary, overweight seniors.

The researchers focused on senior citizens for several reasons: 1) Seniors tend be less active than the younger population. 2) They are more likely to suffer from insulin resistance. Insulin resistance is a precursor to diabetes and can play a role in many serious health conditions like cardiovascular disease. 3) Seniors often have “functional limitations”. In other words, it’s more likely for them to have a difficult time moving around and participating in everyday physical challenges.

A total of 136 men and women participated in this study. They were all classified as having “abdominal obesity”, meaning that they were “fat” in the stomach region. The researchers classified men with a waist of more than 40 inches and women with a waist of over 35 inches as acceptable candidates for the study.

The group of 136 was divided into four segments:

  • One segment engaged in resistance exercises. They performed nine different strength training exercising for a total of 20 minutes, three times a week.
  • The second segment performed 30 minutes of aerobic exercise (walking on a treadmill) five times a week.
  • The third group did both aerobic and resistance exercises. This group did 30 minutes on the treadmill and 20 minutes of strength training three times a week.
  • The final group didn’t engage in any form of exercise.

After six months had passed, several key points emerged. Here’s what the researchers found:

  • The combination of aerobic and strength training lead to positive changes with regard to “functional limitations”.
  • Insulin resistance improved by 43% in the combination group. It improved by 31% in the aerobic exercisers and didn’t improve at all in the resistance alone exercisers.
  • Those performing the aerobic and strength training also found an 18% improvement in  “cardiorespiratory fitness”. They were able to breathe more efficiently and didn’t “lose their breath” as easily as they used to.
  • The amount of calories burned was comparable in the combination and aerobic exercisers. Both groups also lost a significant amount of body fat, especially in the abdominal region.

Overall, the combination exercise program was deemed the most advantageous. The researchers commented that, “It is difficult to imagine a more effective strategy for improving overall health  in the elderly”.

Seniors Exercise But Wait, There’s More!

There’s no replacement for exercise. And the information presented above is very encouraging. Having said that, some brand new research published in the February 2009 issue of the Journal of Nutrition may add a little something extra to the mix.

The title of the study pretty much sums it up: “Green Tea (Catechin) Consumption Enhances Exercise Induced Abdominal Fat Loss in Overweight and Obese Adults”.

What the title doesn’t tell you is that the researchers also discovered that the weight loss apparently had nothing to do with the caffeine content in the green tea. That’s a theory that some people have about why green tea aids weight loss. The green tea users also managed to lower their triglycerides significantly during the course of the 12 week study – a serious boost for heart health.

I love learning about practical information, and when it comes to health, I love it even more. So often, in medicine and nutrition, we’re left to guess about what’s best for us.

Today I’ve shared some information that you could conceivably use to improve your state of health and the quality of your life. Please consider putting it to use. Talk to your doctor about it. Go to your local senior center and see if they offer such exercise programs. Search out the resources that will help to keep you well and, possibly, even regain a greater sense of wellness.

PS – For my younger readers, please grab hold of your mid-section. Can you squeeze a good handful (or two) of a soft, squishy substance? If so, you can very well benefit from this same type of exercise routine.

Fat in the abdominal area is sometimes an indication of insulin resistance. Nobody, at any age, needs or wants that. Please do your best to address this potential health risk sooner rather than later.

Be well!

    Thanks a lot for sharing this useful information. Nice research done. Exercise is a must for everyone, might be kids, adults or seniors. Aerobic is one of the best exercise. There are different exercise you can practice daily. The latest is Parkour.

  4. JP Says:

    You’re welcome, Glenn.

    Thanks for the heads up about Parkour exercises.

    Be well!

    The study is flawed. The differences could be due to the fact that the group with best results excercised longer e.i. 30+20 minutes, instead of 30 and 20 rescpectively.

  9. JP Says:

    Michal,

    The take home message, IMO, is that the respective forms of exercise contribute different health benefits and the combination is more effective than either by itself.

    Be well!

    Sorry, but you don´t understand the point. The resarchers concluded that “the combination exercise program was deemed the most advantageous”. However, they overlooked that combined excercises lasted longer and this is not advantage. They compared apples with prunes. Such a conclusion can be done only if the same differnces were observed if all excercise forms had the same duration, e.i. 50 minutes. And it cannot be excluded that the 50 min. duration of non-combined excercises may have the same or even better effect.

  11. JP Says:

    I understand your point, Michal. Thank you for making it. The study could have been designed in a better way to be sure.

    Be well!
