Exercise in a Pill?

Timeless Health Tip

Scientists at the University of Texas Southwestern Medical Center (UTSMC) have identified a protein enzyme that, when overactive, produces the muscular effects of aerobic exercise - without the exercise. They think that someday they will be able to isolate the enzyme and put it in a pill.

Exercise in a Pill?

There are two different fibers in muscle - fast twitch and slow twitch. Slow twitch muscles contract slowly, but keep going for a long time, while fast twitch contract rapidly but quickly become tired. The enzyme, called calmodulin-dependent protein kinase (CaMK), transforms fast-twitch muscle fibers to slow-twitch muscle fibers, which are much less likely to fatigue and are necessary for endurance.

The enzyme has only been tested on mice so far, so we can't get too excited as yet, but a little hope isn't a bad idea! It could take some time - perhaps even decades - before it could be marketed and distributed.

When it does become available, it will likely be prescribed only to those who have congestive heart failure. What does make this good news for everyone is it shows how far research is coming in helping us with our problem of excess weight. With every little discovery we are one step closer to finding real solutions - which will not take decades. Maintain your hope - but also maintain good diet and exercise habits - with those you can never go wrong.
