New York Times: Money often buys higher-quality, but not always when it comes to running shoes

HPRC Fitness Arena:
Money often buys higher-quality goods, but not when it comes to running shoes, experts say.

The New York Times Health section has an article that looks at the cost of running shoes, and found that low- and mid-cost shoes within the same brand cushioned runners’ feet just as well as high-cost ones — sometimes even better.

In short, money often buys higher-quality goods, but not when it comes to running shoes, experts say.

Running a marathon can affect your heart

Businessweek.com is reporting on a new study that suggests that running a marathon can damage your heart, with more than half of the segments in the heart's main pumping chamber typically functioning a little under par during the race. The good news is that other parts of the heart pick up the slack and the changes reverse within three months or fewer after the run, the researchers found.

The end result is that the study shows that the more fit and trained a runner is, the less effect the strain of a marathon was found to have on the heart.

Fluid replacement during operations or exercise

HPRC Fitness Arena: Physical Fitness
Filed under: Hydration, Exercise
Staying hydrated is important, but is there a "best" way to hydrate?

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.

Not all carbohydrate foods are equally effective

HPRC Fitness Arena:
Certain foods raise blood sugar better than others. It's important to what to eat after a moderate to high intensity mission or exercise.

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.

Eat a PBJ post-workout

HPRC Fitness Arena:
Want a great post-workout meal?

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.

For other post-exercise snacks please visit the Warfighter Nutrition Guide.
