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.
Your heart rate varies with every heartbeat. When it varies more, it’s good for your health and performance. Heart rate variability (HRV)—a way to track how your heart rate rhythmically goes up and down—helps you objectively assess your mind-body optimization. HRV measures the time interval between one heartbeat and the next. It can be affected by many factors, including fitness, age, body position, and even the time of day. HRV also decreases during periods of stress. You’ll feel less stressed—and more resilient—when your HRV level is high. Your heart rate speeds up when you inhale and slows down when you exhale too. Breathing at certain paces impacts HRV and—in turn—the mind-body connection and performance. Since you can learn to control your breathing, you also can improve your HRV.

Dietary supplements don’t require approval by the Food and Drug Administration (FDA) before being put on the market. That means unless a product has been tested in a laboratory, there’s no way to know its true contents, including potentially problematic ingredients and possibly even ones not listed on the label. So how can you tell if a product really contains what it says on the Supplement Facts panel? Check the product label to see if it carries a seal from an independent, third-party organization. For more information and examples of third-party organizations, visit the OPSS FAQ about third-party certification.
Recent DoD policy changes now allow transgender persons to openly serve in the military. News about this and a greater presence of transgender people—at school and on TV—might prompt questions from your kids about what it means to be transgender and gender-nonconforming.
People typically are assigned a sex—based on their genital anatomy—at birth. Assigning individuals into 2 sex categories—male or female—also means there are expectations that one will behave in a way that aligns culturally with his or her assigned sex. For example, in the U.S. and most other western cultures, a girl is expected to play with dolls, while a boy is expected to play with toy cars. The behaviors and expressions of one’s sex make up his or her gender.
For some kids and adults, the sex identities they were assigned at birth don’t align with their internal genders, or “gender identities,” that they believe more accurately reflects their true selves. When your internal view of yourself is different from your external, assigned sex, then you come to consider yourself transgender or “trans.” Read more...
Healthcare providers commonly treat kids with attention-deficit hyperactivity disorder (ADHD) with medication and behavioral therapy, but proper nutrition can improve your child’s success in school and at home too.
Nutrient-dense foods boost kids’ overall health, especially for those with ADHD. They often consume poor diets consisting of mainly white flours and sugars because kids with ADHD crave these foods. However, these foods are missing valuable nutrients needed for muscle growth and brain development. Inadequate fuel can impact your child’s behavior, mood, sleep, and even lead to constipation. However, your child can grow and perform well when he or she eats a variety of foods: whole grains, protein, dairy, fruits and vegetables, and water. Read more...
While it’s good to “think positive” when setting lofty goals, think about what might prevent you from actually getting there too. Imagining success should (and can) inspire you to put in the hard work needed to do well. However, dreaming of how things could be down the road might make them feel so tangible that you don’t do what’s needed to get there.
That’s why it’s more realistic to picture where you want to go along with what might be in your way. Then you can either decide that the goal is out of reach or plan to deal with the obstacles in order to succeed.
Here are four steps to help you overcome obstacles and reach your goals:
- Identify an important goal that’s challenging and achievable. For instance, maybe you’re aiming to improve your PFT score by 20%.
- What will it mean to accomplish your fitness goal? Maybe you picture yourself being more active with your family at home and then performing well on a mission.
- Consider what stands between you and your goal. You can still keep your eyes on the prize. But you need to recognize the obstacles. Maybe exercising in the dark makes you nervous, or you’re less organized, or even tired, so it feels like an uphill battle.
- Strengthen your awareness and face obstacles with an “if…then” plan. Here’s an example: “IF my fear of nighttime running creeps up, THEN I’ll put on my high-visibility clothing and stick to well-lit streets.” Here’s another: “IF I find myself disorganized and grasping for time, THEN I’ll walk around the block while planning my day.” Or how about: “IF I feel tired when I come home this evening, THEN I’ll take a short walk or jog and go to sleep right after.” If…then plans help you face your fears instead of hiding from them.
Try this four-step method to shift from just dreaming about important goals to tackling the obstacles along the path to accomplishing them. And you might find this works even better if you combine it with setting SMART goals.
Drug testing can happen at any time in the military. If you’re taking or considering dietary supplements—especially ones considered “high risk”—you’ll want to make sure your product won’t affect your test results. High-risk supplements are among those marketed for bodybuilding, performance enhancement, sexual enhancement, and weight loss. They sometimes contain ingredients (listed on the label or not) that could cause a positive test result. If you have a product that you think might cause a problem with a drug test, contact one of the DoD Drug Testing Centers on the OPSS infosheet “Dietary supplements and drug testing.”
School’s back in session, and kids with attention-deficit hyperactivity disorder (ADHD) struggle with focus, hyperactivity, and schedules. It’s especially important for them to keep a consistent routine, limit screen time, and get a good night’s sleep.
Regular routines are important for all kids, especially those with ADHD because they’re more likely to get distracted. And some might have a harder time completing their tasks. A consistent routine helps them stay on track. Tip: Hang a “daily routine” chart on your refrigerator. Make sure it includes tasks your child must complete in the morning—such as brushing teeth and hair, washing his or her face, and changing clothes—before heading out the door. Add bedtime tasks such as packing his or her lunch and backpack to the chart too. Using the chart as a guide to repeat the same behaviors every day can help your child stick to successful morning and evening routines.
Children and teens with ADHD tend to spend more time in front of screens than other kids. Follow the American Academy of Pediatrics recommendation and limit your child’s screen time to 1–2 hours daily. And set up a “screen-free zone” in your house—where everyone agrees to avoid TVs, cell phones, tablets, game consoles, and laptops. Encourage your kids to move more instead: They can head outdoors or play team sports. Aerobic exercise also can help reduce inattention, impulsivity, and hyperactivity.
A bedtime routine can help kids with ADHD improve their sleeping patterns too. Make sure to establish and maintain a set bedtime. And consider removing all media and screens from your child’s bedroom. Kids also should avoid consuming caffeine before heading off to dreamland.
Your core is more than just your abs: It includes lots of other muscles that stabilize your shoulders, hips, and pelvis. Strengthening all of your core muscles can be difficult with traditional “ab routines” done on the ground. Crunches aren’t the only way to strengthen your core. So, get up off the floor and add something new to your core-workout routine.
HPRC offers a video series on vertical core training. These routines are not only good for your six-pack, but improve strength in your back, hips, legs, and shoulders—all critical components of core strength. Whether it’s lifting ammo cans or loading a truck, a strong core will help you move safely and efficiently.
Visit HPRC’s Muscular Fitness and Flexibility page to learn more. Use these videos to guide you through various exercises that will help improve total core strength, flexibility, and stability for everyday activities and optimal performance too.
Aim to eat five servings—about 2½ cups—of vegetables every day to boost your health and performance. Don’t like vegetables? Here are some tips to help even die-hard “veggie haters” work a few vegetables into their meal plans.
- Grill your vegetables! Grilling adds those familiar tastes that most people enjoy. Baste vegetables with your favorite low-fat marinade for flavor. Tip: Roasting vegetables in the oven makes even bitter-tasting ones taste sweeter. Try asparagus, onions, and summer squash.
- Add vegetables to foods you already love! Add pureed butternut squash to macaroni and cheese, chopped onions and peppers to pizza, grated zucchini or carrots to pasta sauce, or black beans to canned soup. Omelets are great vehicles for a variety of veggies: spinach, tomatoes, mushrooms, and more.
- Drink up! There are lots of tasty vegetable juices in grocery stores nowadays. Look for low-sodium versions or vegetable-fruit juice blends. Try custom-blending your own by mixing bottled carrot juice with your favorite fruit juice. Or whip up a nutritious smoothie instead!
- Challenge your taste buds. Do you truly not like broccoli, or have you just never had it prepared in a way you like? Change your cooking technique and try again. Try baking, roasting, grilling, sautéing, steaming, or eating vegetables raw for a different flavor and texture.
- Flavor it up. A little flavor goes a long way with vegetables. Prepare veggies using a pinch of sea salt, fresh or dried herbs or spices, a sprinkle of Parmesan cheese, or a swirl of balsamic vinegar to turn up the flavor.
- Get adventurous! Just because you hated something as a kid doesn’t mean you’ll feel the same way about it as an adult. Visit More Matters for other ideas and recipes for vegetables.
Boost your meals with powerful veggies! The recommended intake of vegetables varies depending on your age, weight, and calorie needs. This chart from the U.S. Department of Agriculture will guide you.
An adverse event from a dietary supplement is any undesirable health effect you might experience. It could be mild or life threatening. It’s important to know how to recognize symptoms that might impact readiness. To learn how, read the Operation Supplement Safety (OPSS) FAQ on adverse events, which also has a link to a form for reporting adverse events to the Natural Medicines Comprehensive Database. All forms are then sent to FDA. Documenting adverse events is an essential part of how the FDA evaluates potentially dangerous dietary supplements.
Manufacturers and distributors also are required to notify FDA of adverse events by calling the 800 telephone number located on product labels.
