Welcome to the HPRC Blog. We've got lots of information here, from quick tips to in-depth posts about detailed human performance optimization topics.
The Army has been working to make sure that the small first-aid kits that soldiers carry are equipped with the proper equipment they might need in an emergency. Here’s the lowdown on the additions to the IFAK II.
The new design is compatible with the Improved Outer Tactical Vest, where it can be mounted on the back, out of the way but still easy to reach. The creators of the IFAK II made individual tabs that “feel” different for each of the kit’s contents—so that when a soldier is trying to reach for something quickly, he/she can easily distinguish between products without actually looking at each pouch. This design is critical for rapid access to first-aid materials.
Other upgrades to the kit include the addition of a second tourniquet, a strap cutter, and a rubber-seal device to treat a sucking chest wound (when a bullet penetrates the lung and interferes with proper air flow). The addition of an eye patch to the kit also can help reduce damage to injured eyes.
Some soldiers in Afghanistan are already carrying the kits to test their functionality and provide feedback that can help lead to even more improvements.
In 2013, the Research Institute of Chicago (RIC) presented the first mind-controlled bionic leg, thanks to support from the U.S. Army Medical Research and Material Command's (USAMRMC) Telemedicine and Advanced Technology Research Center (TATRC). Until now, this technology was only available for prosthetic arms. These brainy bionic legs are still being studied and perfected, but it’s hoped that they will be available in the next few years. This life-changing technology will be able to help the more than 1,600 service members who have returned from Iraq and Afghanistan with amputations. Bionic limbs will make the transition to active duty or civilian life smoother for wounded warriors.
In one case study, a civilian who lost his lower leg in a motorcycle accident underwent a procedure called “Targeted Muscle Re-innervation”. This procedure redirects nerves that originally went to muscles in the amputated limb to still-healthy muscles in the limb above the amputation. As these healthy muscles contract, they generate signals that are detected by sensors within the prosthetic and analyzed by a specially-designed computer chip and program The program rapidly decodes the type of movement the individual is preparing to do, such as bending the knee, and then sends those commands to the leg. This allows the person to walk up and down ramps and stairs and transition between activities without stopping. The user also can move (reposition) the bionic leg just by thinking about it, which is not possible with current motorized prosthetics.
The bionic leg is also showing a decreased rate of falling and quicker response time. Stay tuned for availability of this groundbreaking technology.

Recently, several dietary supplement manufacturers have promoted products for helping with recovery from concussions and traumatic brain injuries (TBIs). The Food and Drug Administration (FDA) is monitoring this issue and is contacting specific companies that are making claims that their products can prevent, treat, or cure concussions.
FDA is warning consumers to avoid using products that claim to treat a concussion or TBI. For more information about the claims and FDA’s response, see this Consumer Update.
Over the last seven weeks, HPRC has run a series on tips for keeping the happy in holidays this season for you and your family.

Activity monitors, also known as “activity trackers” or “accelerometers,” provide an easy way to track how much exercise and sleep you get each day, and some even track your diet. Most are small enough to be a convenient, easy way to keep you accountable and on track for getting the recommended amount of exercise each day. They also offer computer and/or smartphone apps for on-the-go tracking. Check out our comparison chart of some of the more popular trackers to find the right one for you and your budget.
Last week we highlighted stretching your mind and body while taking a break from the holiday season. This week’s tip—with New Year’s Eve upon us—is to check your drinking.
It’s easy to overindulge during the holidays. Celebrating usually causes us to both eat and drink too much. This holiday season, be careful that you don’t drink too much. According to the American Psychological Association, a “moderate” amount is no more than two drinks a day for men and one for women and older people. One drink is defined as 12 ounces of beer, five ounces of wine, or 1.5 ounces of spirits. Also, remember this important acronym: “HALT: Never drink if Hungry, Angry, Lonely, or Tired.” To learn more about what to look for or how to cut back, check out the factsheet “Do you drink too much?”

In April, FDA announced that the substance was illegal for use as an ingredient in dietary supplements, after which the number of products that contained it rapidly declined.
Only 19 products were added to the list over the past 12 months; none were actually new to the market, but just ones that came to our attention as other products with DMAA became unavailable. By comparison, 46 products were discontinued/reformulated, and 86 DMAA-containing products (or versions of products) appear to have disappeared completely from online retail availability. Only 61 products remain on the “active” list, and many of these are from non-U.S. sources; some still on the list may have eliminated (or are about to eliminate) DMAA, but their manufacturer/distributor websites are unclear as to their status.
HPRC will continue to update its list and report of “Dietary Supplement Products Containing DMAA,” with the most recent version dated 12 December 2013, but updates will appear less often than in the last two years.
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.
Happy New Year! HPRC wishes you and your loved ones a happy and healthy 2014.
The New Year is a perfect time to reflect on where you are in your life and where you want to be in the coming months. When you set your resolutions, think about setting one around your primary relationships. Is there something that you could focus on this year that would make your relationships stronger? For example, what about taking a romantic getaway with just your partner at least once this year? Or how about staying in closer contact with your parents or best friend? Also, think about incorporating other areas of Total Force Fitness in your resolutions, such as physical fitness, nutrition, mental resilience, and your environment.
