Here is an article from a friend of mine after having this discussion at a conference a few weeks ago on nutrition for military, police, fire fighters — our tactical athletes. The need for more carbs for highly active people but it goes deeper than that:
Nutrition and the Tactical Athlete
As a firefighter understands fire, the warrior must understand war. Maintaining combat effectiveness via proper training and nutrition is a big part of this.
Nutrition is the one factor affecting each person multiple times per day and therefore has the greatest impact on a person’s overall health and fitness level. Scientists agree that 70+% of diseases known to man are caused by lifestyle factors and many can be treated via lifestyle changes. Nutrition being the number one approach.
For the tactical / endurance athlete this fact does not change. Being fit does not mean being healthy and the level of proper nutrition should address both of these factors.
The level of combat readiness literally translates into life and death. This fact makes the tactical athlete an extreme endurance athlete. Long hours of high stress from limited sleep, MRE’s and massive physical demands provide very unique nutritional demands.
Combat is high stress. The modern day tactical athlete often operates night and day for months without rest. This massive amount of stress not only results in mental breakdown leading to PTSD but also physical breakdown leading to physical injury and less combat effectiveness. This high stress results in elevated cortisol levels. Elevated cortisol causes 3 main problems in the warrior. One, lowered immune functions thus making the warrior more susceptible to illness, two, protein breakdown from muscle to keep blood sugar steady which leads weakness and to number three, increased body fat.
The three issues can be offset with proper nutrition in the field. For years ultra-endurance athletes have developed techniques and products for maintaining endurance days on end during a race. Polysaccharide gels, powders and liquids aimed at keeping blood sugar levels steady along with hydration and electrolyte balance are the key. A tactical athlete must maintain steady blood sugar, water and electrolyte balance. MRE’s do not do this and often have the reverse effect of maintaining combat readiness.
How does a tactical athlete maintain steady blood sugar? First, start by figuring your personal caloric needs. Google is full of BMR calculators. Second, plan to eat 65–70% of your diet from a polysaccharide source. (whole grains, sweet potatoes, brown rice, beans). Third, calculate your caloric intake of starchy carbs. 1 gram of carbs is 4 calories. Finally, use an online resource to calculate the carbohydrate intake from your food.
Example: BMR = 2000cals per day. Add 600 calories per day for moderate activity levels = 2600 calories per day consumed. 2600 x .65% of carbohydrate = 1690 calories from starchy sources. Each gram is 4 calories, 1690 / 4 = 423 grams of carbohydrate consumed per day. Finally to calculate how much carbohydrate is in the food you eat I suggest the online resource myfitnesspal.com.
There is much more to understand regarding nutrition. But, much like a firefighter studies and understands fire those whom wish to become or are tactical athletes must study and understand nutrition. We will further expand on this topic in the next edition.
