As many runners have done, I have been pouring over articles to assist with training, gear and nutrition as I get closer and closer to Grandma’s Marathon. While I have noticed many trends, there are a few items I want to add from my own experience. Since my farming operation is based on raising pigs, I will admit an obvious bias towards pork consumption, so bear that in mind as I ramble on.
Exercise of any sort involves the use of your muscles. Running requires extensive use of your largest muscles, and a day or two after exercise, soreness can set in (at least until your body acclimates). Exercising muscle breaks them down slightly (the soreness) and triggers a reaction for your body to start building more muscle fibers to accommodate future strain. In order for your body to do this, it needs protein, and more importantly, it needs the amino acid building blocks in the proper balance to create protein. (We balance our pigs’ feed rations based on amino acids, feed intake and location in the growth curve)
While in college, my nutrition professor mentioned that the amino acid proportion in eggs was 94% balanced for humans, meat (pork, beef, poultry, lamb) was in the 70-75% range and plant proteins ranged from 10-50%, depending on the source. Based on this, meat is a great source of protein for athletes, because we have used the animal’s biological system to take the raw products (usually corn, soybean meal, ethanol byproducts and a vitamin & mineral premix) and convert it into a flavorful and nutritious meal. It is interesting that the one meat commonly considered OK to eat by running publications is chicken. A 2006 USDA study found that six common cuts of pork contain 16% less total fat and 27% less saturated fat than they did 20 years go. It also found that pork contains NO artery-clogging trans fats, and it includes essential vitamins and minerals.
A serving of roast pork tenderloin, for example, is an excellent source of protein, thiamine, vitamin B6, phosphorous and niacin, and a good source of riboflavin, potassium and zinc. Pork is a lean, low-calorie, relatively low-cost source of high-quality protein – 1 3 ounce tenderloin has 2.98 grams of fat compared to 3.03 grams fat for the same-sized serving of skinless chicken breast.
When you do prepare pork, do your best not to overcook it. The best aid in doing this is a meat thermometer. When the interior of the cut reaches 150F, remove the pork from heat and cover, letting it rest for another 5 minutes. The heat near the surface of the meat will continue to penetrate inward, raising the temperature past 160F, but removing the pork from heat will keep the moisture inside and help retain tenderness.
As far as training goes, I have had my extensive long runs (20 and 22 miles) over the last two weekends. I was satisfied overall with how they went. I am looking forward to auditioning the Pork Power racing shirts at the Med City Half-Marathon starting in Byron, MN this Sunday. After that, one more large mileage week before the taper, then Grandma’s on June 19.
