The study I cited was published in the Journal of Applied Physiology. A summary of the study is published on-line and titled How training affects hormone to different modes of exercise

An excerpt from the highlights of the study findings includes the following:

- Total Testosterone: There was an increase in total testosterone after exercise, particularly after resistance exercise. There was a significant session by time interaction due to the pronounced decline in total testosterone during recovery from resistance exercise. Area under the curve results indicated that the SED subjects had significantly greater total testosterone concentrations compared to END or RES subjects.

Note: SED refers to sedentary test subjects, END are endurance-trained subjects, and RES are resistance-trained subjects (i.e. weight training)

Is there a thread about that?

Just so it doesn't become a forum ;-)

60 years of liberal pussywhipping takes its toll.

If this trend continues, we may elect a democrat as president in 2008. We came dangerously close in 2004.

My guess is that men are not as physically active these days...

Is this study some kind of joke? They are basing their studies on tests of men in their sixties; what idiots. Of course their testosterone levels are decreasing you twits of science. Geez.

from about 1,500 men in the greater Boston area

That just about explains it.

Thanks for posting that. I never wanted to exactly ask anyone, but have been wondering at certain..err...Changes..since I took up trail biking three years ago. Honestly like rolling back the odometer to half my age. My wife laughs out loud every time those Viagra ads show up on TV.

I kept reading about bike riding causing certain types of damage-They do not seem to though.

So I think the person who posted that men are simply more lethargic or idle lately might be onto something.

I asked my wife and she told me to tell you that this study is lame.

"So I think the person who posted that men are simply more lethargic or idle lately might be onto something."

I have no doubt that the great exercise of trail biking has yielded benefits to your body that both you and your wife can appreciate, but don't credit those benefits necessarily to any effect involving testosterone.

Read Post #101 again carefully, noting the last sentence of the excerpted results of the study cited.

There is an inverse relationship between total testosterone concentrations in male subjects versus physical conditioning of the subjects. Men who have a sedentary lifestyle are found to have a higher baseline concentration of total testosterone than men who engage in regular endurance or resistance physical training. It's counterintuitive, but several studies yield this result.

There is a spike upward in testosterone during and immediately after exercise for men, especially when lifting weights, but a sharp decline occurs during recovery phase after exercise and it returns to baseline levels.

Exercise yields numerous benefits for men, including improved muscle mass and strength, joint flexibility and motion, improved blood circulation, stamina, and improved self image. All of these benefits contribute greatly to virility and far outweigh the slightly lower total testosterone baseline concentration typically found in physically conditioned men.

Oh, OK, thanks.

As long as this effect is not a "Going Out Of Business" surge!

Interesting. You are correct, it is counterintuitive. You are also correct when you note the side effects of exercise outweigh the difference in horomone levels!
