Add some water to your workout

Try changing up your exercise routine; give your body a break with a challenging pool workout.

Water/pool workouts and swimming are great ways to give aching joints a break or recover from an injury and still get in a good workout. Exercising in the water provides the same aerobic fitness benefits as exercising on land. In fact, exercising in water may be less work for your heart; it pumps out more blood per beat, and heart rates are slightly slower. What’s more, pressure from the water speeds blood flow back to your heart, where your blood gets the oxygen that your muscles need during exercise.

Aquatic exercise is great for most people, including older and younger folks. Consider jumping in a pool to reduce stress and the risk for overuse injuries and as an alternative to your usual exercise routine.

Meditation can improve pain tolerance

HPRC Fitness Arena: Mind Tactics, Total Force Fitness
Recent research indicates that meditation may help you deal with pain and related anxiety.

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.

For more information see the write-up on the University of Wisconsin's news page or the research article.

Operation Bushmaster

Operation Bushmaster, a field training exercise for medical students, reminds us that both physical and mental performance are key aspects of success for military healthcare practitioners.

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.

CHAMP and HPRC host a conference on functional movement assessment

CHAMP and HPRC are hosting a conference in conjunction with ACSM and NASM on September 10–11, 2012, on “Preventing Injury through Functional Movement Assessment: What We Know, What We Don’t Know, and Where We Go From Here.”

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.

Back in action: Regaining peak fitness

Getting back into shape takes dedication and persistence, and doing so safely and correctly may help prevent injuries.

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.

Stress Fracture Prevention: Strengthening the Lower Extremity Muscles

Maintaining strength and flexibility in the lower extremities is one of the many important steps toward decreasing the likelihood of developing the small cracks in a bone commonly known as stress fractures.

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:

Ankle Flexion

Single Leg Push-off

Forward Hurdle Run

Seated Calf Stretch

Standing Dorsi-Flexion (Calf Stretch)

Supine Hamstrings Stretch

Barbell Calf Raises

Jump and Reach

Agility Ladder: Lateral Shuffle

Alternate Leg Push-off

Barbell Jammers

Before beginning any exercise program, however, make sure to consult with a medical professional, especially if you are more than 45 years old.

The lowdown on stress fractures—and how to prevent them

Stress fractures are chronic injuries that occur most often in the lower extremities. Prevention is key and can be helped through adequate attention to nutrition, training surfaces, and footwear, as well as gradual progression in training.

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:

  1. 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.
  2. Check your footwear and make sure it matches your training. Replace footwear that is old or worn.
  3. 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.
  4. 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.

It is important to recognize a stress fracture and seek medical advice early, as discussed in Clinics in Sports Medicine. The Mayo Clinic provides information on the symptoms of a stress fracture.

Marines address boot camp injuries

Reducing injuries during boot camp is a priority for the Marine Corps; athletic trainers keep watch over recruits to ensure the 13-week training is as injury-free as possible.

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.

Progressive overload injuries

Don’t get injured by trying to do too much too soon. Ramp up your exercise regimen slowly and steadily to avoid getting hurt—and having to start over.

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.

Future Trends: DARPA looking to develop “performance underwear” for warriors

DARPA researchers envision a future of soldier technology that will improve Warfighter effectiveness by employing high-tech underwear.

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.
