Why Your Brain Hates Exercise
Can You Exercise Too Much?
Each week on TestTubePlus, we pick one topic and cover it from multiple angles. This week's subject is health and fitness. Why is it so hard to stay fit? What motivates some of us? How much does genetics play a part in athletic ability? Is there a limit to human's abilities? In the first episode, Trace talked about some of the reasons why our brain hates exercise. Yesterday, Trace was joined by guest host Amy Shira Teitel to discuss supplements and if it's possible to exercise too much. Today, Trace and Amy go over the social science of staying fit.
According to HowStuffWorks.com, improved muscle tone can increase sexual gratification since orgasms depend on multiple muscle activity. In the case of the more mature man, improved cardiovascular fitness can be critical for maximum sexual function. Staying fit seems to cause an increased libido and can counteract the decrease in testosterone levels which often occur with age. University of California, San Diego, tracked 78 middle-aged men on an aerobic exercise program. The subjects exercised at moderate intensity for 60 minutes a day, three or four days a week. After nine months of continuous exercise, these subjects reported that their sex life was more satisfying as far as stamina and orgasms.
But exercise can also have benefits on the brain, too. Studies on the structure of the brain show that exercise promotes growth of neurons in the ventral hippocampus, which is the area of the brain that regulates anxiety. Young neurons are usually more easily excitable than old ones so in theory exercise should give you more anxiety. But it doesn't: Exercise is one of the most-often recommended method of reducing stress, and it has to do with the release of the neurotransmitter GABA.
