When you’re in pain, any relief is welcome. The good news is that researchers have found pain can be managed and alleviated, to a degree, by employing strategies that have you put your focus elsewhere. Meditation is one such strategy. A recent small study examined the experience of pain from fourteen experienced meditators and fourteen inexperienced participants. It turns out that the old adage is true: Practice makes perfect. The experienced meditators experienced pain to a lesser degree and got used to the pain more quickly. They also registered less anxiety than the unpracticed participants. The message? Practicing meditation regularly may improve how your brain handles pain.

In October 2012, students at the Uniformed Services University of the Health Sciences participated in Operation Bushmaster at Fort Indiantown Gap, PA. The exercise involved a simulated combat environment to test the limits of their physical fitness as well as mental resilience. Military medical students were tasked with managing patient flow in an operational environment, such as tactical relocation over uneven terrain and dealing with changes in environmental conditions.
From a human performance optimization (HPO) standpoint, take-home points for the practical exercise included the importance of being physically fit, especially following guidelines for the prevention of back injuries, and implementing mental strategies for coping in high stress situations.
The Functional Movement Screen (FMS) is a tool used to evaluate how people move and identify patterns that could increase the risk of being injured. In a 2011 study conducted by the Consortium for Health and Military Performance (CHAMP), researchers found that FMS scores indicated an individual’s risk for injury. A summary of the most current information published on functional movement assessment demonstrates that the FMS is a reliable tool but that more research is needed. The upcoming CHAMP/HPRC conference will explore the role of functional movement assessment in preventing injury and enabling Warfighters to return to duty quickly, and will highlight areas for future research. Topics focus on the Warrior Athlete and civilian athletic communities, and include the epidemiology of musculoskeletal injuries, functional fitness and movement patterns, and current concepts in, as well as future research considerations for functional assessment tools.
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.
There are several risk factors for stress fracture development, but a 2011 article in Medicine and Science in Sports and Exercise found that maintaining adequate muscle strength and flexibility in the hips, legs, knees, ankles, and feet is of great importance, especially for women. Here are some exercises from the American Council on Exercise that can help you build strength and flexibility:
Before beginning any exercise program, however, make sure to consult with a medical professional, especially if you are more than 45 years old.
The American Academy of Orthopaedic Surgeons defines a stress fracture as a tiny crack in a bone that occurs when fatigued muscles lose their ability to absorb shock and then transfer stresses to the bone. Most stress fractures occur in the lower extremities, and more than half occur in the lower leg and foot.
A stress fracture is an overuse—sometimes referred to as chronic—injury, which means that it develops over a long period of time—from weeks to months. According to a 2011 systematic review published in Military Medicine, stress fracture incidence is high among U.S. military recruits, ranging anywhere from 3% for men to 9.2% for women.
Since it can take several weeks or months for a stress fracture to heal, the best approach is to avoid getting one. Here are some tips for prevention:
- Apply the progression principle of training—gradually increase your training intensity. Slowly incorporate higher-stress activities such as jumping and interval training into your workout. Setting incremental goals can be helpful in carrying out your training routine in a gradual way. And check out HPRC’s Physical Fitness Resources for more information on training and ways to avoid injury.
- Check your footwear and make sure it matches your training. Replace footwear that is old or worn.
- Pay attention to the surface where you train, since some are easier on the bones and joints of the lower extremities. For example, it is better to jog on softer surfaces such as rubber track or grass rather than on concrete. Also, it’s better to begin training on a flat surface and then progress to hills.
- Monitor your diet, specifically calcium and vitamin D intake, and read the National Institute of Health’s Dietary Supplement Fact Sheet on calcium. To learn more about nutrition take a look at HPRC’s Nutrition Resources.
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.
A key concern for Warfighters and athletes alike is getting injured. Continuing to train through a minor injury can turn it into a major one. Even with minor injuries, it’s important to decrease inflammation and increase the range of motion at the affected joint. Two approaches to take are RICE and ISE. Start with RICE—rest, ice, compression, and elevation—to decrease inflammation. Once inflammation is minimized, ISE—ice, stretching, and exercise—helps to increase the range of motion. Using these techniques may reduce inflammation, stiffness, weakness, and/or loss of normal function. Once pain and swelling are reduced, the next step is reconditioning. Exercises that target the area of injury should promote flexibility, endurance, speed, strength, and power while progressing gradually. The main goal of reconditioning is to efficiently decrease pain and increase range of motion. Always check with your physician to rule out more serious injury before proceeding.
