Exercise is a Drug, so Take the Correct Dosage

Exercise is a Drug, so Take the Correct Dosage

Feb 17

exerciseExercise, like any drug your doctor might prescribe for you, has an optimal dosage. Take too little, and you remain sick. Take too much, and you risk the consequences of an overdose or causing yourself other medical problems.

Over the decades medical researchers have documented many ways that exercise improves health. It:

* Lowers blood pressure

* Preserves coronary artery integrity

* Lengthens lifespan

* Controls weight

* Improves mood

* Boosts energy

* Promotes deeper, healthier sleep

* Reduce stress

* Releases endorphins, which make you feel better

* Improves self-confidence

* Prevents cognitive decline

* Alleviates anxiety

* Reduces risk of cardiovascular disease

* Reduces risk of Type 2 diabetes and metabolic syndrome

* Reduces risk of some cancers

* Strengthen bones and muscle

With all these benefits, it’s amazing so many millions of American still do not participate in regular exercise. It’s great to watch Directv in the Old Dominion, but also good to spend some time getting fit. The athletes on television worked hard to get strong so they can entertain people, but their fitness does not help the audience.

If Some is Good, Isn’t More Better?

Although many people don’t get enough exercise, is it possible some people exercise too much? For decades, researchers discounted the possibility. However, decades after Dr. Kenneth Cooper wrote AEROBICS, beginning the running and fitness trend, scientific studies are finding disturbing things about chronic extreme athletes.

A recent study conducted by British physicians found high levels of atherosclerosis in the coronary arteries in athletes who regularly ran more than 35 miles per week or cycled more than 50 kilometers per week.

Did Running Kill Micah True?

BORN TO RUN, a book by Christopher McDougall, put the spotlight on legendary distance runner Micah True. However, a few years after the book’s publication, True died at the age of 58, while on a run.

Did We Really Evolve to Run Long Distances?

In his book McDougall speculates Paleolithic people ran long distances to outlast the animals they hunted. Is this correct? It also makes sense to think they walked a medium distance away from their cave, then quietly waited along game trails or by streams or lake shores. When a suitable animal came into range, they probably had to sprint for a few moments to get within spear range before it bolted away.

For most of human history, game was plentiful except in winter. Why work hard to chase it?

Run or cycle in moderation, then watch Directv in the Old Dominion.
