Even wonder why HPRC refers to the sections of its website as “domains”? They came from an initiative within the Department of Defense that’s outlined in a special issue of Military Medicine titled “Total Force Fitness for the 20th Century: A New Paradigm.” Experts identified eight “domains” of fitness that contribute to the optimal, overall fitness and preparedness of U.S. military forces. With some reorganization (and one exception – medical), these domains are represented on HPRC’s website—Physical Fitness, Environment, Nutrition, Dietary Supplements (originally part of nutrition), Mind Tactics (psychological, behavioral, and spiritual fitness), and Family and Relationships (family and social fitness)—along with a section on Total Force Fitness that addresses how these domains come together to create Human Performance Optimization (HPO) for our military service members.
Armed Forces Day was created in 1949 to honor Americans serving in the military. In 1962 President Kennedy established it as an official holiday on the third Saturday in May. Why should Armed Forces Day get attention on a DoD human performance optimization website? As director of HPRC, I think this holiday has the potential not just to honor the Armed Forces but for the Armed Forces to do what it has done many times in the past: respond to a crisis for the United States. The Armed Forces go to war to support a political strategy, and no national strategy at the present time is more critical than the war on obesity and tobacco. DoD has chosen these as part of the National Prevention Strategy. So how do we fight this war? We the military can start by setting the example for the rest of the country by bringing into our homes the practices of physical fitness and good nutrition as well as a smoke-free environment. We can make fitness and nutrition a priority for our spouses and children. We can make fitness and nutrition family activities that can promote good health, form stronger families, and make family members happier, closer together, and more productive. The military family can be the model for the civilian community to copy—a family working together toward a common goal of health and fitness. The payoff is tremendous in the present and the future. The military can be the beginning of a movement across the country to fight and win the war on obesity and tobacco use. The HPRC website has lots of helpful information in this war on obesity and tobacco. Check out the site (www.hprconline.org) and look under Physical Fitness, Nutrition, tobacco (under Mind Tactics Performance Degraders), and Family & Relationships. There is much that can be done. Join the war on obesity and tobacco. Set an example in your community for healthy living. Oorah! Hooah!
In a recent study investigating risk factors for discharge from Army Basic Combat Training (BCT), researchers concluded that increased risk for both men and women was associated with failure on the initial two-mile run test. The current Physical Fitness Tests (PFT) or Physical Readiness Test (PRT) use a one and a half to two-mile run test to assess cardiovascular, or aerobic, fitness.
When mapping out a fitness program, learn the components of the FITT principle and apply them for each type of training. FITT stands for “frequency,” or how often; “intensity,” or how hard; “type,” or the kind of activity; and “time,” or how long. Progression (see below) is also an important part of an exercise plan. Using the FITT Principle, here are some guidelines to help optimize your cardiovascular fitness.
Frequency. The U.S. Surgeon General and other U.S. government agencies recommend physical activity on three or more days a week.
Intensity. According to updated guidelines The American College of Sports Medicine (ACSM) recommends adults engage in moderate-intensity exercise (i.e., at 40-60% Heart Rate Reserve (HRR)) five days a week or vigorous-intensity exercise training (i.e., at ≥ 60% HRR) three or more days a week. They also recommend a combination of moderate- and vigorous-intensity exercise. You can use this calculator from Kirtland AFB to determine your HRR.
Type. ACSM defines aerobic activities as being continuous, rhythmic, and using large muscle groups, such as your lower and upper body muscles. Examples of these kinds of activities are running, biking, swimming, rowing, and jump roping.
Time. The Surgeon General, ACSM, and American Heart Association recommend expending at least 1,000 calories per week through exercise (i.e., in addition to calories burned through normal everyday activities). This can be achieved through moderate-intensity exercise, as described above, and should last about ≥ 30 minutes per day for a total of ≥ 150 minutes per week; or with vigorous-intensity exercise for ≥20 minutes per day for a total of ≥75 minutes per week. The maximum safe duration is unknown, but exercise lasting more than an hour and a half increases risk of overtraining and/or overuse injuries such as stress fractures.
Progression. During the initial phase of an exercise program, ACSM recommends increasing duration (minutes per session) gradually. Increasing 5-10 minutes every one or two weeks over the first four to six weeks of an exercise program is reasonable for healthy adults. After an exercise routine has been maintained for one month or longer, it is reasonable to gradually increase frequency, intensity, and/or time over the next four to eight months. As a general rule of thumb, though not scientifically backed, increasing your workloads or volume by 10% will also help you gradually progress your exercise program.
Due to the repetitive and rhythmic nature of aerobic exercise, overuse injuries can occur as a result of your training. Cross training—training with a variety of aerobic exercises—is recommended. Examples of this would be alternating running, swimming, and rowing exercise sessions.
Part two of this series (upcoming) will address the muscular strength component of PFT/PRT.
For whatever reason, sometimes we get off track with our fitness regimens—maybe it was an injury, a move, or just life that intervened. Getting back to a peak level of fitness after time away should be done gradually. Injuries such as tendonitis—which could become a long term issue—can occur as a result of doing too much, too fast. The American College of Sports Medicine (ACSM) recommends increasing duration (minutes of exercise) 5-10 minutes every one or two weeks over the first four to six weeks of an exercise program.
With the holiday season upon us, finding time for our usual workouts can sometimes be difficult. Two great physical fitness resources are the American College of Sports Medicine (ACSM) and the American Council on Exercise (ACE). Each has online workouts that you can try for free.
For a total body workout that you can do at home with free weights, try this total body workout from ACE that includes videos of the warm-up, the workout, and the cool-down. For a total body workout without additional equipment, try this at-home workout.
If you have less time, try this Basic Bodyweight Strength Training Program from ACSM.
Fit in these workouts in at home through the holiday season to keep you on track.
Swimming is an excellent way to reduce the risk of disease. It works your entire body and activates all the major muscle groups; contributes to muscle strength, flexibility, posture, and endurance; promotes weight loss and stress reduction; and improves cardiovascular conditioning by lowering your resting heart and respiratory rates and making blood flow to the heart and lungs more efficient. Swimming is also very low risk for injury because it places stress on your bones, joints, and connective tissues, thanks to the buoyancy of the water. Swimming 15 to 30 minutes each day can have a very positive effect on your overall health.
The Los Angeles Times is reporting on how the Marine Corps has hired 27 certified athletic trainers—most with experience tending professional and college athletes—to oversee training for enlisted recruits and officer candidates at sites throughout the United States. According to the article, this is a new direction for the Corps: Not that long ago, the drill instructors might have dismissed recruits who complained of being injured and ordered them back into action.

Many who suffer from a lot of stress also have high blood pressure and do not exercise. People who practice some form of activity or exercise benefit from less stress associated with personal, family, and work situations. Reducing stress will improve your health. Exercise helps improve your stress tolerance and also can strengthen your cardiovascular system, increase endorphin levels, and keep you mentally focused. Bike rides, power walking, and yoga are some of the many inexpensive, time-efficient ways to improve your general fitness and reduce stress. The Mayo Clinic has more good advice on how and why to reduce stress.
Continuing to work out is important because you do not want to lose the strength and endurance you have built up. Reversibility occurs when training stops or decreases. To ensure that you don’t lose your progress, you must “use it,” or else you will “lose it."
In any training program, you should follow a day of hard, intense exercise with one or even two days of “easy” training. This gives the body and mind time to recover before the next “hard” day. In addition, this helps prevent overtraining and encourages variation in your workouts.
