Can You Exercise Too Much?
Are Elite Athletes Born or Made?
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. For the last two episodes, Trace was joined by guest host Amy Shira Teitel to discuss exercise supplements and how working out can help you have better sex. Yesterday, Trace tried to answer if elite athletes born or if anyone train to be an olympian. Today, for the final episode, he asks: when will humans become the perfect athletes?
Records for the fastest a person can run, swim, and jump are frequently being broken. Take olympians: they keep breaking records. But it's widely agreed that this is due to improvements in technology: for example, we have lighter bikes, deeper swimming pools,
lighter and stronger pole-vaulting poles, and synthetic tracks. Even the clothing olympians wear can make a big difference. In 2008, many swimmers, said they couldn't win a gold unless they were wearing a certain kind of swimsuit (Speedo's LZR bodysuit, which was a spinoff of NASA technology). As a result, Nike allowed their sponsored swimmers to wear the competitor product.
What was so special about this suit? It reduces skin friction drag 24 percent more the previous Speedo racing suit fabric, and it compresses the body, improving efficiency 5 percent. The more skin covered by this suit, the more potential it has to reduce skin friction drag: it's literally slicker than human skin. It's no surprise that swimmers wearing these suits are breaking records. When you compare these suits to the ones that swimmers in the 1950s wore, it's no competition. So technology definitely plays a big role in athletics, and Trace explains where this might be taking us in this episode of Test Tube Plus.

"Although extolling all the benefits of exercise seems impressive, it is apparent
that this approach by itself does not assure consistent exercise compliance for most
individuals. Regular exercise is a complex, multi-factorial behavior that exercise
