If you sweat a lot during exercise drink lots of fluids, but do not exceed 1.5 L/hour. Sip frequently rather than gulp; drinking small amounts of fluids at a time are more effective than drinking large amounts occasionally. Also, start drinking before you become thirsty.
As stated in the Warfighter Nutrition Guide (chapter 5) , certain foods raise blood sugar, or glucose, levels better than others. Ultimately, blood glucose from foods you eat are stored in the muscles and liver, in the form of glycogen, to supply energy for future physical activity.
The term glycemic index (GI) is used to describe how high a particular food will raise blood glucose. A high GI food is more effective for replenishing muscle and liver stores of glycogen than one with a low GI. Immediately after a moderate/high intensity mission or exercise, eat foods and beverages that have a moderate to high GI to replenish the glucose used up.

The New York Times Well blog features an article on research that studies the differences of men and women sweat.

It’s important to eat something after a strenuous workout to replenish muscle stores of carbohydrate and have plenty of protein available to repair the body. Try a peanut butter and jelly (PBJ) sandwich for a great post workout meal! It’s cheap and packed with nutrition if you use natural peanut butter without added sugar and fats, and whole-grain bread.

In the 10/18 In the Crosshairs, we linked to a story on from CNN.com that reported on military medical researchers that have developed a blood test that can detect if someone has suffered a concussion or a mild traumatic brain injury.
In response, Wired.com has an article in their Danger Room section that calls into question the research that has been done by the Army.
CNN.com is reporting that military medical researchers have developed a blood test that can detect if someone has suffered a concussion or a mild traumatic brain injury.
Traumatic brain injury (TBI) is a big concern for the military, particularly milder forms, because unlike TBI, milder injuries cannot be seen on X-rays, CT scans or MRIs. Having this test would be useful not only for the military but for civilians as well.
Rather than sitting during the day, stand when possible. During your next phone conversation, stand up. Standing burns more calories by engaging more muscles and prevents inactivation of fat burning enzymes. It uses more blood glucose which may prevent adult onset diabetes. According to this article, simply standing can improve your cholesterol and overall health – an amazingly simple strategy to improve fitness!
KENS Channel 5 in San Antonio, TX has posted an article on their website that reports that, according to the military, the number of prospective recruits are just too fat to enlist, which is making it difficult to fill their ranks.
The article cites a non-profit group called Mission Readiness, made up of retired senior military leaders, who feel there is a solution to the problem.
The group has a three-point approach that would solve the obesity problem for prospective recruits:
- Get the junk food and high-calorie beverages out of our schools.
- Increase funding for the school lunch program.
- Support the development, testing and deployment of proven public-health interventions.
