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.
Beets are often overlooked in the produce aisle, but they have been gaining popularity for their potential cardiovascular health and performance benefits. This is because beets contain a high amount of nitrate, which improves blood flow to your heart and muscles. While the performance-enhancing benefits of nitrates from beets have yet to be fully established, there are many other reasons to include beets in your lunch or dinner menu. Beets are a great source of fiber, antioxidants, potassium, magnesium, folic acid, and vitamin C—all important nutrients to keep you at the top of your game.
If beets aren’t your favorite food, there are plenty of other nitrate-rich (and nutrient-rich) vegetables, including arugula, rhubarb, lettuce, celery, radishes, and spinach. Try eating roasted beets or a salad with dark-green, leafy vegetables two to three hours before your next workout. Keep in mind that eating a variety of high-quality foods is key to optimal performance, so for more information on proper fueling, see HPRC’s “An Athlete’s Guide to Everyday Nutrient Timing.”
HPRC has often posted information about the U.S. Food and Drug Administration (FDA) and safety surrounding the topic of dietary supplements. But there’s another Federal agency watchdogging the supplements industry: the Federal Trade Commission (FTC). One of the primary missions of FTC is to protect consumers from unfair or deceptive business practices. That includes misleading or false advertising and claims. FTC advertising law states that all claims by dietary supplement manufacturers and distributors must be substantiated before they are made. So far in 2014 alone, FTC has issued press releases regarding unsatisfactory practices by dietary supplement companies. Most recently, one marketer admitted to wrongfully marketing weight-loss benefits of green coffee beans through appearances on television talk shows. Please see the FTC press release for more information.
Just as FDA has a reporting system for adverse effects associated with dietary supplements, FTC has a consumer complaint process that you can use. For this and other consumer information related to dietary supplements, visit this FTC web page.
If you’ve ever worn a cast, you know that the muscles in that area are weak when your cast comes off. Or maybe you’ve experienced this feeling after being bedridden with other injuries. Muscles lose strength from not being used, but there’s more to it than that: Your brain also “forgets” how to send the signals needed to move parts of your body.
Mental imagery helps your brain “remember” how to move your body. When you use imagery that focuses on the physical (not just visual) sensations associated with moving specific muscles, your brain sends the same kinds of signals actually used to move those muscles. Doing imagery while you’re injured may reduce strength loss.
Does this mean that if your elbow is in a cast, or if you simply prefer couch time to working out, you can get bigger biceps just by thinking about doing curls? No, but it does mean that during any stage of recovery from an injury, even before you are able to move, you can play an active role in making rehab go more smoothly. And it reinforces what earlier research tells us: Mental imagery can augment physical practice, helping your body to learn physical skills.
You may know that calcium and vitamin D are important for healthy bones, but do you know that magnesium plays an important role too? People who eat enough magnesium in their diet tend to have higher bone mineral density (a measure of bone strength) than those who do not. Not getting enough magnesium can put you at risk for osteoporosis (weak, fragile bones).
So make sure you get at least the Recommended Dietary Allowance (RDA) for magnesium, which is 400–420 mg for men and 310–320 mg for women. According to the Institute of Medicine’s Committee on Military Nutrition Research, only 30% of military personnel meet or exceed the recommendations. However, this doesn’t mean you need to start taking magnesium supplements. You can easily get enough magnesium from eating a variety of magnesium-rich foods in each food group:
- Vegetables—dark green, leafy vegetables such as spinach
- Fruits—bananas, avocados
- Protein—beans, legumes, nuts, and seeds, as well as fish and seafood
- Grains—fortified cereals and whole-grain bread, rice, and pasta
- Dairy—milk, yogurt, and soymilk
As an added benefit, many of these foods are also rich in other nutrients, such as calcium, that help keep your bones strong. For additional information, see the Magnesium Fact Sheet from the Office of Dietary Supplements. And for information on other nutrients related to bone health, see HPRC’s Eating for healthy joints and bones.
Drinking a lot of alcohol in a short amount of time—“binge drinking”—can lead to alcohol poisoning. It’s very serious and can even be deadly. Binge drinking involves more than four drinks for women and more than five for men over a relatively short period. The Centers for Disease Control (CDC) reports that an average of six people die from alcohol poisoning every day, with the majority being men between 35 and 64 years of age. Life-threatening signs of alcohol poisoning include seizures, not being able to wake up, fewer than eight breaths per minute, 10 seconds or more between breaths, and low body temperature. If you’re with someone who shows any of these signs, seek help immediately. That Guy, an alcohol education campaign from the Department of Defense, recommends that if you’re ever worried about someone’s alcohol intake, never let them “sleep it off.” To learn more, visit this web page from CDC on “Alcohol Poisoning Deaths.” Not sure how much is too much? Read HPRC’s article, “Had enough to drink?”
With New Year’s resolutions upon us, weight loss is often at the top of the list for many. However, before you consider a dietary supplement to help your weight-loss goals, be aware of the Food and Drug Administration (FDA) warnings that these products don’t live up to their claims. Even worse, some can result in serious harm.
Many dietary supplement products marketed for weight loss have been found to contain hidden prescription drugs or compounds that have not been adequately studied in humans. FDA continues to identify “tainted” products and warns consumers to stay away from these tainted products. You can read more about this in FDA’s consumer-health article “Beware of Products Promising Miracle Weight Loss” and watch their video. Also, be sure to check out the Operation Supplement Safety (OPSS) FAQs about Weight Loss for additional information on weight loss and dietary supplements.
As your children head to college, it’s hard to know how much to let go and still support them as they tackle new challenges. It’s a major milestone for both kids and parents, and the milestone is especially relevant for Department of Defense parents (80% of whose children go to college, compared to 66% of graduating high school students in the U.S. with non-DoD parents).
During this transition, “helicopter parents” (so-called because they hover) frequently text or call, continue to make decisions for their children, and directly intervene when problems arise between their kids and other people. It makes sense to let go and give your children “space” as they transition into adulthood. After all, how else is your emerging adult supposed to learn self-reliance and financial independence? But protective parenting instincts can overcome what might otherwise make sense.
Helicopter parenting can essentially be an overdose of previously good instincts. To your kids, it can feel as though you’re trying to control how they act or feel. Even though you have good intentions, your behavior may feel intrusive to them, and it might not be obvious that “solving” your kids’ interpersonal, school, or work crises actually causes problems. In fact, helicopter parenting usually leads kids to feel less engaged with college, more anxious and depressed, and less pro-active.
Here are some tips for less-direct ways to help that also keep you grounded instead of “flying away” as a helicopter parent:
- Resist the urge to make decisions for your kid. Instead, ask open-ended questions to get him or her thinking.
- Ask your kid to set his/her own boundaries for how much he or she wants you to intrude (such as how often to text or call), and accept them!
- Encourage your kid to have direct conversations with other important people such as professors.
- Give tips on how to do things such as grocery shopping (rather than just doing it yourself).
- Avoid tracking grades; encourage your kid to set his or her own goals and sub-goals.
If you are a helicopter parent, you don’t have to change radically overnight. But make sure you talk to your kids about the changes you’re planning, and then gradually make them happen. Give your kids more power and autonomy, such that you become a trusted advisor rather than a dictator. The milestone of college isn’t a time for parents to withdraw completely, but it is a time to trust that some of what you taught your children actually sunk in.
Returning to duty after a mild traumatic brain injury (mTBI; also referred to as acute concussion) requires a special recovery process. Until now, procedures used by military healthcare professionals were largely based on sports-related mTBI practices, which are not always appropriate for returning Warfighters to military activities and demands. Medical and military experts worked together to develop new recommendations for returning service members to military activity after mild traumatic brain injury. The six-step process includes progressing from rest through light to moderate activity and exercise and eventually to unrestricted activity. Patients cannot progress until they are symptom free at any given stage in the process. Almost 84% of military brain injuries in 2014 were from mTBI/concussions. Some of the most common causes of concussions occur in non-deployed setting. While not all mTBI/concussions are preventable, there are things that you can do to reduce your risk in your day-to-day life:
- Always wear a seat belt when driving or riding in a vehicle.
- Wear a helmet when suitable (for example, on a bicycle or motorcycle).
- Create safe living spaces to reduce falls. Remove or secure potentially hazardous items from floors and overhead.
- Be aware of your surroundings. Try these Mind Tactics Performance Strategies to improve your ability to control your attention.
You’re watching what you eat. You’re exercising regularly. You’re doing everything right. But for some reason, your weight-loss goal is just out of reach. It seems those “last 10 pounds” are often the hardest ones to shake! Fortunately, with continued effort and persistence, you likely can achieve your weight-loss goals.
If you haven’t done so already, be sure to speak with your healthcare provider or a registered dietitian to make sure the goals you’ve set for yourself are realistic, healthy, and sustainable. After that, it’s time to get to work.
Go back to square one. That is, make sure you’re as careful about what you choose to eat now as when you first started on your weight-loss journey. Sometimes we lapse into old habits over time and start “allowing” unhealthy choices to creep back into our diet patterns. Keeping a food diary will help you keep track of what you’re really eating. And don’t forget to watch your portion sizes.
Be a weekend warrior. Many people find it harder to make healthy choices on the weekend—tailgate parties, family celebrations, and road trips all offer opportunities to “slip.” But eating healthy is a full-time job, so it’s important to plan ahead: Take a low-fat dish that you’ve prepared and choose restaurants where you know you’ll have healthy options available.
Stand up for yourself. Literally. Standing, rather than sitting, can burn as many as 200 to 300 calories per day and can help prevent many types of disease. Find as many opportunities in your day to stand, walk, and move as much as you can. Check out HPRC’s blog about “sitting disease” for more information about the risks of sitting too much.
Shake things up. Varying the type and intensity of your exercise is a great way to challenge yourself and prevent boredom—and can make a big difference toward achieving your goals.
Whatever you do, don’t give up. Achieving and maintaining a healthy weight is important not only in the short term (for your performance as well as your career) but also in the long term, reducing your risk of many diseases including diabetes, heart disease, and certain types of cancer.
You probably realize that learning from your mistakes can enhance your performance. But do you know it can also enhance your relationships? Acknowledging mistakes can be easier said than done. Before you can learn from your mistakes, you have to admit to them.
Admitting mistakes can be powerful. When you own up to your mistakes in relationships with other people, it makes it easier for the other person to really forgive you, allowing both of you to move forward. Whether in your interactions with others or in learning skills such as SOPs for handling a weapon, fully acknowledging your mistakes enables you to learn from them.
But sometimes you may have difficulty admitting that you screwed up. If you’re a perfectionist, for example, your identity can get wrapped up in being the person who always does things right. Admitting you screwed up can open the door to intense feelings such as shame and doubt. However, hiding from those feelings won’t work; they’ll eat at you in some way. Instead of hiding from them, try facing them.
Here are some tips for owning up to your mistakes and moving forward:
- Face shame and doubt by simply being mindful of those feelings, letting them come and go.
- Recognize when you’re falling into a thinking trap such as “I must be perfect,” and experiment with more helpful thoughts such as “I strive for excellence.”
- Forgive yourself and others when mistakes happen, trusting that people really do learn from their mistakes.
Mistakes happen. Give yourself (and others) permission to label mistakes as changeable behaviors rather than reflections of who you are.
