Fitlist Page at MSNBC


I just ran across a great page at MSNBC with a bunch of celebrity fitness tips. Most of the info is pretty basic but it is also really interesting to have so much in one place

Also there are links at the bottom of the page to news stories on Fitness and Health that MSNBC is covering

AntiOxidants for sports and fitness


Here is information from eVitamins on the value of Antioxidants for sports

Why do athletes use it?*
Some athletes say that antioxidants help protect the body from free radicals.
What do the advocates say?*
Antioxidants such as vitamin C, vitamin E, CoQ10, glutathione, and alpha lipoic acid are important supplements for everyone, but especially for those who exercise on a regular basis. The rational is that exercise is a highly oxidative process and, as a consequence, produces free radicals from aerobic metabolism. Antioxidant compounds help alleviate this process.

There is conflicting evidence whether the best time to supplement with an antioxidant is before or after a workout.

How much is usually taken by athletes?
Most research has demonstrated that strenuous exercise increases production of harmful substances called free radicals, which can damage muscle tissue and result in inflammation and muscle soreness. Exercising in cities or smoggy areas also increases exposure to free radicals. Antioxidants, including vitamin C and vitamin E, neutralize free radicals before they can damage the body, so antioxidants may aid in exercise recovery. Regular exercise increases the efficiency of the antioxidant defense system, potentially reducing the amount of supplemental antioxidants that might otherwise be needed for protection. However, at least theoretically, supplements of antioxidant vitamins may be beneficial for older or untrained people or athletes who are undertaking an especially vigorous training protocol or athletic event.

Placebo-controlled research, some of it double-blind, has shown that taking 400 to 3,000 mg of vitamin C per day for several days before and after intense exercise may reduce pain and speed up muscle strength recovery.3 4 5 However, taking vitamin C only after such exercise was not effective in another double-blind study.6 While some research has reported that vitamin E supplementation in the amount of 800 to 1,200 IU per day reduces biochemical measures of free-radical activity and muscle damage caused by strenuous exercise,7 8 9 several studies have not found such benefits,and no research has investigated the effect of vitamin E on performance-related measures of strenuous exercise recovery. A combination of 90 mg per day of coenzyme Q10 and a very small amount of vitamin E did not produce any protective effects for marathon runners in one double-blind trial,14 while in another double-blind trial a combination of 50 mg per day of zinc and 3 mg per day of copper significantly reduced evidence of post-exercise free radical activity.15

In most well-controlled studies, exercise performance has not been shown to improve following supplementation with vitamin C, unless a deficiency exists, as might occur in athletes with unhealthy or irrational eating patterns.16 17 Similarly, vitamin E has not benefited exercise performance,18 19 except possibly at high altitudes.

Carbohydrates for Energy


There are essentially three types of diets these days. There is the Atkins diet which stresses low to zero carbs. There is the low fat diet which stresses no fats and there is a vegetarian diet which stresses low fat and low protein but allows higher carbohydrates.

Today I would like to demystify the need for carbs. And then in the future we can deal with fats and protein as well as what diet is best.

Where to find Carbohydrates

Carbohydrates are the main component of grains, rice, fruits and vegetables. You essentially need carbohydrates for energy and fibre. When your body is looking for a source of energy it tends to use the simplest form available. The very simplest form of energy is glucose and although this is pure table sugar its next closest form is found in fruits as sucrose. These carbohydrates are called simple carbs because they are easy for your body to break down into energy.

If your body can not find one of these sources of sugar for energy it will move down the food chain and try one of the next most easily available carbs next would be grain based or what we look at as ‘white’ carbohydrates such as bread, potatoes, or rice. (Chocolate bars although not an official food group are closer to sugar than veggies or other carbs). Your body will use any of the complex carbs as well as vegetables for fuel before moving to fats or proteins.

Now that we can see where our carbs site in the energy chain it is a good idea to see what happens when we eat one and what happens to our energy from them. When you eat a sugar it immediately increases your blood sugar otherwise known as your insulin level.

What happens when you rely on sugar?

When you blood sugar spikes from sugar, chocolate, or pop you will get a bit of a euphoric feeling from this extra unneeded energy but because it is quick pickup it is also a quick drop for energy and thus you will get a sugar crash 30-45 minutes after the initial energy peak, this is very bad and bad for your body. If on the other hand you only had potatoes or bread or rice for your carbs you would have no nice spikes but no crashes either and would feel after a couple days on a very more even keel, you would feel like you energy is pretty good all the time but never to low or to high. This is the key that we are looking for.

Tomorrow I will write more about bad foods just for a nice way to start minimizing them not to scare people away from them. But now you know energy wise why you would rather get you energy from more complex carbs than simple carbs.
