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.

It’s how you react to stressful situations—not the causes of stress themselves—that can affect your future health. Research has shown that people who react more strongly and remain “stressed out” longer are more likely to develop chronic diseases such as heart conditions and arthritis.
Even if you can’t control the stressful situations you find yourself in, you can learn to control how you react to them. Simple mind-body strategies such as deep breathing and cognitive reframing can help. Try some of the relaxation strategies from the Navy & Marine Public Health Center website the next time you find yourself reacting to a stressful situation and see if they make a difference.
In October 2012, students at the Uniformed Services University of the Health Sciences participated in Operation Bushmaster at Fort Indiantown Gap, PA. The exercise involved a simulated combat environment to test the limits of their physical fitness as well as mental resilience. Military medical students were tasked with managing patient flow in an operational environment, such as tactical relocation over uneven terrain and dealing with changes in environmental conditions.
From a human performance optimization (HPO) standpoint, take-home points for the practical exercise included the importance of being physically fit, especially following guidelines for the prevention of back injuries, and implementing mental strategies for coping in high stress situations.
Understanding how stress affects you both mentally and physically in high-stress situations is important for optimal performance—which is why training under stress is a central part of combat preparation. Knowing what your reactions are, when to pause and take a deep breath, how to use positive self-talk, when to recalibrate one’s physical responses, and how to recharge (sleep and proper nutrition) after a stressful event are key for being at your peak mental performance. Getting support from comrades and using appropriate humor also can help relieve stress.
The holidays can be hard for families when a loved one is deployed. This blog entry from the Defense Centers of Excellence, “Preparing Your Family for the Holidays Apart,” has some tips for the holidays for the family at home, including:
- Continue gift exchanges even if family members are apart, as traditions are important.
- Socialize with your friends and family as usual; don’t isolate yourself.
Family members can even get creative with holiday traditions, such as making holiday ornaments with names of loved ones and/or writing letters to be opened during the holiday season.
Part of a comprehensive fitness program involves improving your muscular strength and endurance. One way to figure out how much weight you should be lifting is to determine your one-repetition maximum (1RM). The American College of Sports Medicine recommends lifting 8–12 repetitions of 60-80% of a person’s 1RM to improve muscular strength and endurance. However, doing a 1RM test isn’t always feasible or safe if you don’t have someone to spot you. Instead, try using this this quick-and-easy calculator to estimate what your 1RM should be for a given exercise.
The holidays can sometimes be a stressful time filled with loved ones and activities. This year, try practicing one of the healthy stress busters you can find on HPRC’s website—by yourself or with your family. For example, give brief meditation a try.
You can even try this as a family: Have someone lead the meditation and give occasional cues. Note that this generally works better with older children!

Lugging around heavy weights and other exercise equipment while traveling or on deployment isn’t the most practical idea. Pack a couple of suspension-training straps, however, and you’ve got part of a well-rounded training routine covered. Suspension training has gained a lot of popularity among both civilians and service members alike, and more and more gyms are now offering suspension-training classes. Once the straps are securely anchored to something that won’t move and is sturdy enough to hold your weight, place your hands or feet into the loops, and your body weight enhances the effectiveness of exercises such as push-ups, lunges, core strengthening, and more. While there are various ways to adjust and adapt the exercises for less experienced exercisers, this type of workout requires some initial joint and core stability. There is also potential risk of injury, especially for beginners. Before you try this for the first time, it’s a good idea to get some advice and guidance from a suspension-training professional.
The Centers for Disease Control and Prevention (CDC) has reported that the consumption of energy drinks by service members can lead to sleep deprivation and impaired performance. The report outlines a study of more than 1,200 service members deployed in Afghanistan that found roughly 45% of those surveyed consumed at least one energy drink daily. Those who consumed three or more energy drinks per day—about 14%—had sleep issues that disrupted their performance. While more research is needed to determine the full effects of energy drink consumption on sleep, service members should be aware of their daily caffeine consumption.
The Army has several resources to help you train for the Physical Fitness Test (APFT) and to build and maintain your fitness levels throughout the year. HPRC has issued a series of documents to help you increase aerobic fitness as well as muscular strength and endurance. Under the Army PRT tab in our Physical Fitness Program Guides section you will find links to videos that demonstrate specific preparation, conditioning, and recovery drills found in TC 3-22.20, Army Physical Readiness Training, as well as other sources of information to guide you in developing and carrying through on your training commitment.
Not being able to quiet your mind at night can be very frustrating— and it’s not just an “adult” problem. If your child has difficulty sleeping because of a restless mind, try setting aside some “worry time” during the day. Help your child create a “worry box” and personalize it through art. Children can write down their worries—each on a separate index card—and deposit the worry in the worry box. Doing this while getting ready for bedtime can be a good way to spend some quality time with your child every night. For more information on sleep strategies, visit HPRC’s Mind Tactics section.
