HPRC Fitness Arena: Physical Fitness
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.
Brazilian Jiu-Jitsu—or BJJ—focuses on ground fighting techniques, also known as grappling. You can start your training at a level appropriate to your physical fitness, but ultimately you will find that your endurance increases as your opponent also learns the techniques designed to dominate. Although BJJ requires little to no physical strength—mainly technique and balance—you will find that your muscle tone and mass increase gradually without requiring weight training.
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.
When training, an athlete should be specific about methods of training that meet the needs of the activity he or she is training for. To achieve an optimal performance level, a sprinter will train in a different way than, for example, an endurance athlete such as a marathon runner. Make sure that you “stress the physiological systems” right for your type of activity. In other words, if you are going to compete in a race, you need to run to become a better runner. Likewise, if you are going to compete in a cycling or swimming event, you must perform those exercises to become better. Wanna be a better tennis player? Play tennis! Although a well rounded program that includes strength training, aerobic conditioning, and flexibility exercises will improve your general fitness, to improve at a specific activity or sport you must perform that particular exercise.
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.

Overuse injuries are a common risk associated with the rigors of physical training. A healthy tip to implement into your training program is to gradually increase your training workload by just 10% each week. This will help—but not guarantee—to reduce the risk of muscle or joint injury such as tendonitis or stress fractures caused by repetitive trauma. In essence, keep the progressive changes in your activity levels gradual, listen to your body, and make incremental adjustments in time and intensity until you reach your new fitness goals.
The future of Warfighter technology may someday include a high-tech “performance underwear” bodysuit that will protect soldiers from injuries, monitor vitals, and help soldiers maintain body energy while on the battlefield. This, according to an article in Wired.com, is what DARPA (Defense Advanced Research Projects Agency) hopes to one day accomplish. DARPA describes this so-called performance underwear concept as being an “adaptive, compliant, nearly transparent, quasi-active joint support suit,” which can “mitigate musculoskeletal injury caused by discrete dynamic events while maintaining soldier performance.” According to the official solicitation notice, the “DARPA Warrior Web program…will develop the technologies required to prevent and reduce musculoskeletal injuries caused by dynamic events typically found in the Warfighter's environment. This will be accomplished by a system (or web) of structures, in the form of a skin-suit, that are compliant and transparent until injury-causing conditions activate appropriate changes in the web structure.”
Sounds good…except there is one catch: Right now, military technology of this caliber doesn’t exist. The Wired article indicates that DARPA plans to introduce its future performance tool this month to a meeting of potential researchers. Their goal? To find a company that might be able to create a compliant, Warfighter-wearable, quasi-passive, adaptive suit system that can reduce injuries and retain optimal warrior performance.
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.
If you exercise in the cold, consider these tips from the American Council of Exercise (ACE; Exercising in the Cold) to stay safe. Check how cold it is before you go out, and do not exercise if the conditions are too extreme. Be sure to dress warmly (keep your head, hands, and feet warm) and dress in layers that can trap insulating dry air near your skin. In addition, avoid blowing air into your gloves and mittens because it will add moisture, which will cause your hands to be colder. For more detailed information, you can read the original American College of Sports Medicine position stand: prevention of cold injuries during exercise.
In order to optimize your health and physical fitness, you should consume a balanced diet as recommended by the U.S. Department of Agriculture. According to the USDA, you should limit consumption of sodas and trans-fat foods; replace solid fats with oils such as olive, canola, and safflower oils; reduce intake of added sugars and sodium; replace refined grains with whole grains; limit your alcohol intake; increase your intake of vegetables, fruits, and fat-free or low-fat milk; and replace some of the meat or poultry in your diet with seafood. More details and guidelines can be found on HPRC’s Nutrition domain, especially the recent articles on the new USDA MyPlate program and online availability of the 2010 Dietary Guidelines for Americans.
