Self-myofascial release, commonly known as “foam rolling,” has caught on in gyms and physical therapy clinics—and for good reason. It can help loosen tight muscles, tendons, ligaments, and fascia (the covering of the muscles), increasing your range of motion (that is, how much your muscles and joints can move). Foam rolling can also reduce the muscle soreness that results from working out too hard or too long. One recent study found yet another benefit: If you foam roll before a workout, it can possibly reduce the fatigue you feel during the actual session, thus increasing the length of time that you can exercise or even how hard you work out. How does foam rolling work? More research is needed to understand all its effects, but it is known that muscles have specialized receptors called Golgi Tendon Organs (GTOs) that are sensitive to changes in muscle tension, so when you roll over them, the muscles relax.
How do you get started? First, check with your doctor to make sure that it’s safe for you to do, and then follow these guidelines:
- Don’t foam roll over recently injured areas.
- More density = more pressure, so choose a low-density foam roller if you are just starting, and then progress to one that’s more dense.
- Foam roll over tension spots you feel in your muscles, or use continuous rolling over a muscle to loosen it.
- Gradually increase the amount of time you roll over each muscle. Generally, one or two minutes per muscle group is recommended if you are just starting.
It’s time to get up off the floor and add something new your core-workout routine. Crunches aren’t the only way to strengthen your core. The Human Performance Resource Center now offers a six-video YouTube series on Vertical Core Training. Your core is more than just your abs; it includes other muscles that stabilize your shoulders, hips, and pelvis. Whether it’s lifting ammo cans or loading a truck, a strong core will help you move safely and efficiently. Use these videos to guide you through various exercises that will help improve total core strength and stability for everyday activities and optimal performance. You can also find these videos and other training resources online in HPRC’s Physical Fitness domain.
Many Warfighters exposed to bomb blasts in the field walk away unscathed—or so it would seem. However, there could be some damage they’re not “seeing.”
Many Warfighters survive bomb blasts without obvious injuries, but the high-pressure shockwaves from explosive blasts can cause serious physical damage to a Warfighter’s eyes. In fact, up to 10% of all blast survivors experience significant eye injuries, either from projectiles thrown into their eyes, eye perforations caused by the high-pressure blast waves, or effects on the eyes associated with traumatic brain injury (TBI). If you were exposed to a blast while in the field but were not otherwise injured, don’t wait to set up an appointment with your eye doctor. Your vision is extremely important! Don’t let potential eye injury go untreated. For more information on how blast waves can affect your vision, visit the Vision Center of Excellence.
You’ve been training, and now you’re in pain. It could be you’re having a painful introduction to one of your tendons. Strong tendons connect your muscles to the bones in your body and help you move by pulling on the bones when your muscles contract. Damage to tendons can occur from repetitive activities (including running and firing your weapon repeatedly over an extended period of time) or from sudden movements that put too much stress on a tendon. If you can’t avoid these activities, then pay attention to the warning signs that a tendon could be reaching its breaking point: pain, especially when moving the affected area; swelling over the area of pain; and, possibly, loss of motion in the joint.
The best way to avoid having to get treatment for tendonitis is to prevent it from happening in the first place! Follow these tips:
- Overall health: Maintain a healthy diet and weight, and check out HPRC’s Nutrition domain.
- Posture and body mechanics: Pay attention to your posture and make sure that you use correct body mechanics, especially when lifting and moving heavy objects.
- Maintain adequate muscle strength so your body can react to stresses you place on it.
- Maintain adequate flexibility.
- Consider proper workout gear, especially footwear; check out this HPRC article for more information.
- Activity modification: Rest the affected area. This could mean taking some time off from activities that cause pain and further damage. For example, if you’re a runner with Achilles tendonitis, try biking instead until the tendon has healed enough.
- Ice: Cold can help to decrease pain and swelling.
- Physical therapy: Gentle stretching and strengthening exercises, as well as massage, might help but should be done under the supervision of a healthcare provider.
- Anti-inflammatory medications: Ask your physician about medications that can help your condition.
- Bracing or casting might be needed in severe cases.
You should see your doctor right away if you experience fever, redness, and warmth in the affected area, or multiple sites of pain. For more information on injury prevention, check out HPRC’s “Preventing common injuries,” which covers six specific areas of injury: wrist and hand, knee, ankle, rotator cuff, back, and IT band.

Veterans who served in the U.S. and abroad between September 2001 and March 2010 were four times more likely than civilians to suffer from severe hearing loss. In fact, two of the most common disabilities affecting service members today are hearing loss and tinnitus, says the Hearing Center of Excellence (HCoE). Hearing loss and tinnitus seriously impact force readiness as well as the emotional and social well-being of those affected.
However, not all hearing loss results from the noise pollution Warfighters experience in the field. Many everyday exposures, such as your MP3 player or loud music in your car, can be just as damaging as firearms or helicopters. To maintain good hearing and operational readiness, Warfighters must use safe listening practices at all times. HCoE recommends these safe listening practices:
- Never listen to your MP3 player at maximum volume.
- Following the “60:60” rule: 60 percent maximum volume on your MP3 player for no more than 60 minutes a day.
- Take periodic breaks of 15–20 minutes when listening to loud music to allow your ears to recover.
- Select headphones or earbuds designed to remove background noise.
- Exercise caution when listening to music in the car. Listening in a confined space increases the risk of hearing damage.
- Wear hearing-protection devices such as earplugs at concerts, sporting events, parades, and other high-noise situations.
For more information on how to protect your hearing, as well as treatment and rehabilitation for hearing loss, please read this article from HPRC and visit HCoE.

Injury prevention is critical in maintaining optimal performance and operational readiness. Ankle sprains, knee pain, and back pain are very common injuries in the military. Take the time now to protect yourself from injury, and you’ll be glad you did later. Read our , compiled from our recent injury prevention series of posts.
Chondromalacia is a knee problem that can have a number of different symptoms, including pain. It can your ability to exercise, but even more problematic is that it can interfere with your ability to meet the demands of your military duties.
Here’s the basic rundown on chondromalacia: In a healthy state, the kneecap has soft cartilage beneath that allows the bone to glide smoothly against the other bones of your knee joint. When the smooth surface wears away, the back of the kneecap becomes rough and rubs the other bone surfaces, causing pain. The key to avoiding this condition is maintaining that smooth surface.
According to the American Academy of Orthopaedic Surgeons, muscle weakness, imbalance, or tightness in the thigh muscles can contribute to chondromalacia. It’s important to maintain strength in your quadriceps and hamstring muscles; follow a strength-training program to develop and maintain strong muscles. Also, make sure that you have enough flexibility in your quads; if the muscles and tendons are too tight, they can force the kneecap to move or “track” incorrectly in the natural groove of your knee joint. If you do a lot of running, make sure your footwear isn’t old and worn, because the shock-absorption of shoes decreases as they age. When it comes to knee pain, an ounce of prevention is worth a pound of cure. Strengthen and stretch your muscles, and you’ll be on your way to keeping your knees ready for action.
