Staying in the physical condition you need for demanding duties and missions means that you are at risk for specific types of injuries, and rotator cuff injuries are common among service members. The rotator cuff is actually a group of muscles key to shoulder movement, including the ability to perform overhead activities. For those who are preparing for the CFT, this includes performing the Ammo Lift.
Warning signs of a shoulder injury can include not only pain and abnormal sounds during shoulder movement but also a decrease in strength and mobility/motion. What can you do about it? First, check with your healthcare provider to make sure that your injury does not require medical treatment. Then:
- Rest your injured shoulder! It is important to allow adequate time for healing.
- Use the RICE and ISE methods.
- Strengthen the muscles that control shoulder movement.
- Make sure that you have adequate flexibility of the rotator cuff muscles.
Of course, it’s always better to prevent injuries in the first place. To help reduce your risk of rotator cuff injury, it’s important to develop the strength and flexibility of the related muscles. For specific information on rotator-cuff exercises and self-care, check out these suggestions from MedLine Plus (a service of the National Institutes of Health) and this conditioning program from the American Academy of Orthopaedic Surgeons.
The Department of Defense (DoD) Safety Review Panel published their findings on DMAA in a recent report now available through HPRC. The Assistant Secretary of Defense for Health Affairs asked the Safety Review Panel to evaluate the safety of DMAA-containing dietary supplement products. The Panel has recommended that the sale of DMAA-containing products be prohibited in all military exchanges.
HPRC maintains a list of dietary supplement products containing DMAA and periodically updates this list. The most recent version can be found on HPRC’s website. Note that, as of the FDA announcement in April 2013, DMAA is illegal in the U.S. as an ingredient in dietary supplements. For more information, visit the OPSS FAQ about DMAA. Operation Supplement Safety (OPSS) can provide service members and their families with information to make informed decisions about dietary supplement use. For the full DoD Safety Review Panel report, see the link on HPRC's Dietary Supplements web page.
The Food and Drug Administration (FDA) has issued warning letters to 15 companies regarding illegally marketed diabetes products that are in violation of federal law. These products are either dietary supplement products or unapproved prescription drugs with claims that they “prevent and treat diabetes” and “can replace medicine in the treatment of diabetes.”
FDA is warning consumers to stop using these products since they may harmful, and their use may interfere with receiving the necessary medical treatment for diabetes. More information is provided in FDA’s “Illegally Sold Diabetes Treatments,” which includes the news release, warning letters issued, and a consumer update.
The physical demands of military life are challenging, and if you’re not prepared, they can lead to injuries. The injury prevention series we’ll be running over the next several weeks will provide you with information and strategies for preventing some of the most common injuries: those to the knee, ankle, rotator cuff, back, iliotibial band and wrist/hand. Prevention is key: Taking time for the small stuff may have big payoff down the road. Much of what the exercises done for recovery after an injury can actually be done to prevent the injury in the first place. Stay injury-free for optimal performance!

Your sunscreen has an expiration date—have you checked it lately? It’s meant to last up to about three years; after that, the active ingredients start to deteriorate, making it less effective and leaving you vulnerable to sunburn and sun damage. Ideally, you should be using your sunscreen often enough that a bottle doesn’t last through the summer. If that’s not the case, check the bottle you’re currently using—if it’s old, throw it out. If you buy sunscreen that has the expiration printed only on the box or wrapper, write the date somewhere on the bottle itself with a permanent marker. Practice safe sun this summer to keep you and your family healthy and happy!
Lyme disease is a serious concern for those who spend a lot of time in heavily wooded areas and a especially for the DoD. It’s common in the United States and around the world and is caught from the bite of two different species of ticks—the deer tick and the western blacklegged tick.
After spending time in wooded or grassy areas, check yourself all over, including your back (enlist a friend or a mirror to help). The early removal of a tick that’s attached to you is key in preventing Lyme, since the tick must be attached for 24-48 hours in order to transmit the bacteria that cause this disease. Ohio State University conducted a study using different tick-removal tools and concluded that all three tools were effective—and confirmed that early removal is more important than the type of tool that is used. The Centers for Disease Control provides easy-to-follow tips on tick removal using just tweezers.
If you know you’ve been bitten by a tick, or begin to notice symptoms such as a bullseye rash (an early sign of Lyme infection) at a bite location, fatigue, chills, fever, muscle aches, or swollen lymph nodes, you should to see your doctor. Blood tests can be used to confirm whether the symptoms are from Lyme disease. If left untreated, more severe symptoms can occur, such as loss of muscle tone in the face (called Bell’s palsy), severe or shooting pain, and heart palpitations. A typical successful treatment includes a course of antibiotics, but there can still be lingering symptoms, called chronic or post-treatment Lyme disease syndrome. When it comes to Lyme disease, the best offense is a good defense. Some tips for prevention:
- Wear your military uniform properly. This can help to prevent tick bites since long pants, long sleeves, and pants that are tucked into boots minimize exposed skin.
- Use insect repellents such as DEET or Permethrin.
- If you are in a wooded area, avoid tall grasses and brush. If this isn’t possible then be sure to follow tips #4–7 below as you are able.
- Perform a thorough skin check—especially of the hair and base of the skull at the hairline.
- Shower within two hours of being outside. This can help wash off ticks that are still crawling on the skin.
- Examine gear and pets for hitchhiking ticks.
- If you have access to a dryer, put your clothes in it for an hour on high heat to kill any ticks.

Barefoot-style, or minimalist, running shoes are still growing in popularity in the military, and the debate continues over whether this style of running prevents injuries or just causes different injuries. There is new research on minimalist running shoes (MRS) and their impact on lower leg and foot injury. After a 10-week study, runners who transitioned to Vibram FiveFinger minimalist running shoes showed signs of injury to their foot bones, while the runners who used traditional running shoes showed none. The types of injuries the MRS runners demonstrated were early signs of inflammation, which may or may not be associated with pain or joint dysfunction. If they are, it might be difficult for the runner to know he/she is actually injured until it is too late and the injury has progressed. More research is needed to determine if other factors (weight, running form/style, mileage, running surface) contribute to injuries associated with barefoot-style running. At least one recent study suggests running style may be a factor. For more in-depth information, read
Increasing the strength of your respiratory muscles (the ones that help you breathe: your diaphragm and the muscles between your ribs) will improve aerobic fitness, especially for long-duration tasks. Respiratory muscle training (RMT) can be achieved through whole-body aerobic exercise, upper-body strength conditioning, and some commercial RMT devices. However, using your military Pro Mask or other commercial mask device as a method of RMT is not going to prepare you for higher elevations. Studies have also found that RMT only slightly improves performance in those who are already aerobically fit, (i.e., military personnel); it has somewhat more benefit for those less fit or with chronic conditions. Your Pro Mask was made to protect your lungs, eyes, and face from chemical and biological agents, radioactive particles, and battlefield contaminants. It does not create enough airflow resistance to help improve aerobic capacity, and it wasn’t designed to be exercise equipment. In addition, there is no scientific evidence to show that using commercial masks at normal altitudes will improve your performance at high altitudes. You can read more from USARIEM about using Pro Masks and commercial products for exercise training, as well an overview of current information and recommendations.
