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.
There’s an old adage you may have heard: “Eat after eight, put on weight.” And maybe you’ve experienced it first-hand: You noticed that eating those late night pizzas and ice cream really packed on the pounds. But was your weight gain due to timing or just the high calorie counts? According to research in the field of circadian rhythms (CRs)—the 24-hour cycle of your body’s biological, hormonal, and behavioral patterns—it seems that when you eat could be just as important to weight gain as what you eat.
Deep within your brain sits a small cluster of nerve cells—a “master clock” of sorts—that’s responsible for orchestrating your CRs. Each biological system in your body works on a different CR schedule, and the master clock keeps all the schedules in sync. For example, CRs influence your body’s production of the hormones that regulate hunger, as well as how your body uses and stores fats and sugar, ultimately influencing your body weight, performance, and overall health. Other hormones, such as the ones that tell you when you’re full, are switched on or off according to a variety of inputs.
The two greatest influences on how well your master clock is able to keep things in sync are light and food. Light tells your brain how much sleep you get (think: eyes closed, less light). Food (smell, taste, and consumption) tells your body to produce a myriad of chemicals. As a result, staying up late at night, working shifts, and eating at all hours of the day and night—whether voluntarily or due to the demands of overseas deployments, training demands, shift-work schedules, and even parenthood—can play havoc with your circadian rhythms.
In an interesting twist, not only do CRs influence hunger and body weight, but excess body fat and/or a high-fat diet may disrupt CRs. This can lead to further weight gain, culminating in a collection of health problems known as “metabolic syndrome.” In the U.S., regular loss of sleep closely parallels the occurrence of metabolic syndrome. In addition, researchers have found that people who sleep less or have poor-quality sleep are more likely to become obese.
What to do? Make a conscious effort to “normalize” your daily routines as much as possible to maintain regular mealtimes. Whether you choose to eat three regular-sized meals or four to six smaller meals a day, space them out through the daylight hours to take advantage of your body’s natural rhythms. Here are some suggestions to avoid eating late at night:
- Try to eat a balanced dinner at least two hours before you go to bed, and take a walk afterwards when possible.
- Sip on soothing herbal tea or flavored water (without sugar).
- Be aware that watching TV (especially food-related ads) can trigger your desire to eat.
- Sometimes it can help to create new nighttime rituals that don’t involve eating, such as light stretching or yoga, taking a warm bath, listening to soothing music, or reading (or listening to) a book.
But if you find yourself up late at night—whether it’s due to a hard day at work, regular shiftwork, or temporary shifts due to jet lag or an infant’s night feedings—resist the urge to snack out of boredom or to “keep your energy up.” Shift workers should pack or purchase a healthy meal to eat during their work hours—one that includes lean protein and complex carbohydrates such as whole grains, fruits, and vegetables. Eat early in the shift if possible, so you’ll have the energy you need to think and move efficiently. Travelers and parents should look for healthy snacks that follow a similar pattern. And try to limit coffee, tea, and other sources of caffeine to just two to four servings a day.
Of course, eating is just one half of the CR equation. Getting enough sleep is important too, so read HPRC’s overview for great tips on how Warfighters can improve their sleep.
Misinformation abounds regarding ideal nap lengths for optimal cognitive performance. You need sleep to function at your best. If you do not get the recommended seven to eight hours of sleep a night, then napping can help. Learn more in HPRC’s Answer, “Nap to be at Your Best Mentally.”
Are you or is a service member you know going through rehab for an injury? Well it should be a comfort to know that there are people out there working hard to make sure you/they receive the best and most advanced forms of therapy and technology during rehab. The Center for Rehabilitation Sciences Research (CRSR) is headquartered at the Uniformed Services University, in Bethesda, MD, and their goals are to find solutions for improving rehabilitative care for injured service members and promote successful return to duty and reintegration. Most of their research is focused in the areas of orthopedic trauma, limb loss, and neurological complications, but they’re not working alone. Their expert team of researchers is partnered with other military medical facilities across the country, and they are committed to educating and training future healthcare providers within the military healthcare system. Visit the CRSR website to learn more about their current research, publications, and events.
Calling all parents of deployed or soon-to-be deployed Warfighters! With your son or daughter’s deployment—particularly the first one—there are probably questions that need answering before your son or daughter heads out. Experts suggest some of the following may help prepare for your child’s deployment:
- Help your Warfighter figure out what responsibilities need to be covered while he or she is deployed and which ones can be managed from abroad. For example, how will the cell phone bill get paid? If he/she has a pet, who will care for it? Are there any bills that can be put on autopayment (such as a car payment)?
- Also, who will keep/store the car, motorcycle, or other belongings? Will anyone be allowed to drive or use them?
- Then there are the tough but necessary questions such as who will make medical decisions if your Warfighter becomes disabled and who will be the beneficiary of death benefits.
- Finally, if your Warfighter has a girlfriend/boyfriend/wife/husband, make sure you know them and have established open lines of communication, as they are often the ones with the most information about your son or daughter while deployed.
Planning for these kinds of details ahead of time can help make deployment(s) go smoothly. You can also encourage them to take advantage of their G.I. benefits for schooling while deployed.

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.

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.
