New OPSS FAQs about DMAA

FDA recently announced that DMAA is not a legal ingredient for dietary supplements and is advising consumers not to purchase or use DMAA-containing products. Read the updated FAQs in OPSS for more.

DMAA, which the Food and Drug Administration (FDA) announced illegal in dietary supplements on 11 April 2013, has been used in many weight-loss, bodybuilding, and performance-enhancement products. HPRC has received many questions about it use by military personnel. To help answer questions about DMAA in general, we put together an Operation Supplement Safety (OPSS) FAQ. OPSS also has FAQs about Jack3d and OxyElite Pro, two popular dietary supplement products. Be sure to check back often as we add answers to other questions about ingredients in performance-enhancing and weight-loss supplements and how to choose supplements safely.

Be flexible in your approach to fitness

It’s good to be strong, but don’t forget about flexibility. Improving it can boost your performance and reduce your risk for injury if done correctly.

Increasing your flexibility with a regular stretching routine can help improve your performance by allowing your joints to move with greater range of motion (ROM) with each step, swing, or turn. Stretching also is a great way to increase the blood flow to your muscles, so it can be helpful prior to PT or sporting events. You can start increasing your flexibility with simple stretching and foam rolling exercises; check out our Performance Strategies for tips on how to begin.

Learning 101: Does your learning strategy measure up?

Many methods can be used to learn information, but some are more effective than others.

Two techniques continue to be found to be effective no matter the age of the learner:

  • Spread out your learning. When you need to learn something new, don’t cram it in right before you need it. Instead, distribute it over time in order to learn the most—and it’ll help you remember more of what you learn as time passes. So start ahead of time and diligently work towards your deadline. Then when you need the information, you may be able to remember it.
  • Be put to the test! Testing allows you to evaluate your knowledge on a subject. Practice tests help you sharpen your skills through direct questioning or applying knowledge or skills in a similar task. So don’t be afraid to put yourself to the test: Use practice tests, flashcards, and/or practice problems to help yourself learn as much as you can and retain what you learn.

Some beloved techniques, such as highlighting and summarizing, may not be as effective as widely thought. Although this research focused on academic learning environments, the same information may be able to benefit military personnel as they learn new topics and skills throughout their career.
There is no one method that is the best for everyone and every task. In fact, combinations of learning methods have yet to be studied. Ultimately, you should judge these techniques according to your specific learning goals and determine what works best for you.

FDA warns: DMAA in dietary supplements now illegal

FDA urges consumers to check all dietary supplement product labels to ensure they do not contain the illegal stimulant DMAA.

The Food and Drug Administration (FDA) has issued a Consumer Update warning of the potential dangers of DMAA, which was announced illegal in dietary supplements on 11 April 2013. DMAA is also referred to as dimethylamylamine and other names. This dietary supplement product ingredient has been used in many weight-loss, bodybuilding, and performance-enhancement products. FDA received numerous reports of illnesses and death from the use of products containing DMAA; commonly reported reactions include heart and nervous system problems as well as psychiatric disorders. DMAA has been the focus of conflicting information regarding whether or not it is a natural extract from geranium. FDA has now found “the information insufficient to defend the use of DMAA as an ingredient in dietary supplements.” Online, FDA also stated, "Dietary supplements containing DMAA are illegal and FDA is doing everything within its authority to remove these products from the market."

Biofeedback for pain

HPRC Fitness Arena: Total Force Fitness
Harness the power of your mind with biofeedback and take control of pain.

Biofeedback teaches you how to control your body’s nervous system in order to reduce pain and stress and promote relaxation. Biofeedback can sometimes relieve musculoskeletal pain such as neck, back, and shoulder pain. It also may work for migraines and stress- and tension-induced headaches. For more in-depth information, read HPRC’s InfoReveal on biofeedback for pain management.

Moms-to-be: Keep the “active” in active duty

Pregnancy is a special time for most women, but it can be especially challenging for women in the military. Exercise before, during, and after pregnancy to help keep you and your baby healthy.

There are more than 200,000 women in the military today—almost 15% of active duty members. Not surprisingly then, pregnancy in the military has become a hot health topic as more and more women choose to serve. Even though most women should exercise during pregnancy, pregnant women still engage in less physical activity than their non-pregnant counterparts. Being active during pregnancy has a lot of health benefits, including maintaining a healthy weight and reducing risk of gestational diabetes and preeclampsia, stress, operative or assisted deliveries, and labor time. Remember this very important message – Don’t ignore pain or fatigue; listen to your body and consult your healthcare provider if you have concerns!

The U.S. Department of Health and Human Services (HHS) recommends that healthy pregnant women engage in moderate-intensity aerobic exercise at least 150 minutes a week, which comes out to around 20-30 minutes a day. Women who already engage in vigorous-intensity exercise can continue physical activity at this level as long as they remain healthy and check with their healthcare provider about when to adjust activity levels (and what limits they should keep in mind). A healthy fetus is not adversely affected even by vigorous exercise, but be careful that you don’t overdo it. Remember that your body is changing with pregnancy—it may take more effort to do the same exercises you did before you were pregnant, and you may not realize when you’re pushing yourself too hard. Monitor your heart rate and use tools such as the talk test to gauge intensity. The American College of Sports Medicine (ACSM) has adopted the age-based heart rate ranges for pregnant women from the Society of Obstetricians and Gynecologists of Canada.

After giving birth, you may find that the “baby weight” gained during pregnancy is stubbornly hanging around.  Excess weight carries a whole host of adverse health risks, so keep moving—even walking for 45 minutes three to four times per week at low to moderate intensity can reduce risk of chronic disease. As with any exercise program, resuming activity after giving birth should be a gradual process (after consulting with your Doctor).

Certain general precautions should be taken with exercise during pregnancy. Avoid contact sports and exercises that increase the risk of falling. Avoid exercises that require stomach-down (supine) positions, with the exception of swimming during pregnancy, which doesn’t place stress on your joints like other forms of exercise do. Regular exercise before you get pregnant can help you prepare for the physical changes that occur during pregnancy and keep you ready and resilient for your family and your military service.

If you’re pregnant, keep in mind there isn’t any consensus about exercising at altitude, so it’s even more important to know the symptoms of acute mountain sickness (AMS). Take time to acclimatize if you travel to altitudes above 2500 meters and allow two or three days before exercising moderately. Wait for complete acclimatization before engaging in heavy exercise.

First and foremost, however, if you become pregnant, consult with your healthcare provider before starting or continuing any exercise routine. Also, each service branch has its own policies regarding pre- and post-natal exercise (available via HPRC’s pregnancy resources page).

Healing through scuba

HPRC Fitness Arena: Environment, Total Force Fitness
Scuba diving is being used to help wounded warriors get back in the swim of things and on with life.

Physical and mental rehab for wounded warriors can come in the form of an undersea adventure. A 2011 study at Johns Hopkins University looked at the effects of a four-day scuba certification class on a group of veterans with spinal injuries. The benefits noted included improved muscle movements, reduction of post-traumatic stress disorder symptoms, and improved sensitivity/sensation for those with certain spinal cord injuries.

Being in the water offers a zero-gravity environment that enables Warfighters to develop the confidence and ability to do activities they may not feel comfortable doing on land. There are organizations that provide scuba lessons and outings for wounded veterans and their families free of charge, such as Adaptive Heroes, Soldiers Undertaking Disabled Scuba (SUDS), and Divers4Heroes, to name a few. Check for programs in your area and explore the great unknown!

Acupuncture for pain

HPRC Fitness Arena: Total Force Fitness
Acupuncture is more commonly being used in the military as a method for pain treatment and management in conjunction with traditional practices.

Acupuncture is an ancient form of Chinese medicine. Thin needles are inserted into the skin at points of the body that are thought to regulate the body's flow of energy (also known as qi or chi). It often is used for common health concerns such as headaches and migraines, carpal tunnel syndrome, and back, joint, and chronic pain. For more in-depth information, read HPRC’s InfoReveal on acupuncture for pain management.
