We've been talking quite a bit lately about exercise and it's impact on hormone production in men.
The evidence continues to mount demonstrating that short and intense bouts of exercise leads to anabolism in the body.
Long duration exercise has an entirely different impact.
Longer sessions place a man in a catabolic state, leading to lower levels of muscle mass and anabolic hormones.
I've watched this play out in real life during the 2012 London Olympics.
Sprinters across the board clearly have the most impressive physiques of all the Olympic athletes.
Let's take a peek at some images now to demonstrate.
Here are the top 3 finishers in the long distance 10,000 meter final.
Gold medalist, Mohamed Farah

Bronze medalist, Tariku Bekele
Now let's see what happens when you reduce your race distance by a factor of 100.Here are the top three finishers in the mens 100 meter final.
Gold medal winner, Usain Bolt
Runner up, Yohan Blake
Bronze medalist, Justin Gatlin
Pretty convincing evidence that short and intense routines push the body to increase production of anabolic hormones.
This increased production takes place because your body needs muscle to perform these intense movements, so it adapts accordingly.
Something to think about the next time you head outdoors to exercise.
