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 is a structured technique to setting goals called “SMART.” It stands for “Specific, Measurable, Action-oriented, Relevant, and Time-sensitive.” Using the SMART technique can help you to jump in to a goal now, fuel your motivation, and help you follow through. Check out HPRC’s Answer “Set SMART goals” to learn how you can put this method to work for you.
HPRC’s Performance Strategies “For single Warfighters coming home” gives you helpful tips for returning home after deployment if you are single. It highlights suggestions that manage your expectations (as well as those of your family and friends), as well as ideas for easing back into “normal” life, establishing an at-home schedule, increasing your support system, and other important aspects to consider.
You’ve heard it all before: You need to get at least 30 minutes of moderate to intense exercise each day to help prevent chronic disease and improve your health. But what do you do for the other 23½ hours? If the answer is sitting (or sleeping), then you might have what is known as “sitting disease.”
It sounds like a joke. Unfortunately, it’s not. If your typical day is spent sitting at a desk, sitting while commuting, sitting down for dinner and TV afterwards, and then going to bed, you’re putting yourself at a greater risk for chronic diseases such as heart disease, diabetes, high blood pressure, and even cancer. Studies consistently show that the more time you spend sitting or lying down, the greater your risk for chronic disease and early death. The simple act of standing up has even more physiological benefits when compared to sitting. The “active couch potato” phenomenon shows that even people who are relatively fit and meet the minimum requirements for daily exercise still exhibit risk factors for metabolic syndrome and other chronic diseases as sitting time increases. Sure, you might take the dog out for his morning walk, or maybe you even did PT before work; but the truth is that the more time you spend sitting the rest of the day, the greater the risk for disease.
You can see from the infographic below (from the American Institute for Cancer Research) that even those who engage in moderate amounts of exercise and physical activity are still at risk for cancer if 12 or more hours in the rest of their day is spent seated or lying down. The risk gets lower as people move more and sit less during the day.
Time is often a major reason that people say they don’t get enough exercise or physical activity during their day. It’s true that work can get busy, but it might just take a little creativity to turn it into a productive work AND physically active day. Here are some tips to help get you up and out of your fancy ergonomic chair.
- Bike or walk to work if possible.
- Take the stairs instead of the elevator (or at least partway if you work on a high-up floor).
- Turn your meeting into a walking meeting.
- Walk down the hall to give someone a message rather than email or call them.
- Stand up while talking on the phone.
- Don’t eat lunch at your desk; walk to the cafeteria or a nearby park, even if you packed your lunch.
- Find out if you can get a standing or walking desk at work.
- Buy a pedometer to track how many steps you take per day.
Doing what you can to increase the amount of time you spend standing, exercising and being physically active will improve your chances of a longer and healthier life,
Food and health are hot topics these days. Just turn on the TV, pick up a magazine, or glance at the margins of your social networking site and you’ll hear and read about the supposed health benefits of dietary supplements containing this or that food component and the promises that they will “burn belly fat” or some similar claim.
Many of these promising food components belong to a group of compounds referred to as phytochemicals—chemicals produced by plants as a means of protecting the plants from various diseases.
Interestingly, when you eat plants (such as fruits and vegetables), the phytochemicals they contain might protect you from disease too. Researchers have found that people who eat a lot of fruits and vegetables have lower rates of heart disease, cancer, diabetes, and many other diseases. Scientists haven’t discovered exactly how these compounds work to protect us, but they have discovered that they seem to have a synergistic effect. That is, the compounds seem to work better in combination, especially when they are supplied in their natural form—whole foods. Consuming isolated single compounds, as in dietary supplements, rarely has the same beneficial effect as eating the whole food. See these resources about fruits and vegetables and how they may impact your overall health.
Focusing on single nutrients (in pill form) is not only expensive, it just doesn’t offer the promise that a balanced, varied diet can. Focus on food, instead. For more information about the benefits of food versus dietary supplements, check out this OPSS brochure, “Nutrition: Fueled for Fitness.”
Achieving and maintaining a healthy weight can be a challenge, especially when trying to juggle the demands of active-duty service, deployments, family, and life in general. Knowing that the next weigh-in is looming can be stressful and can sometimes lead to eating behaviors that spin out of control to become a life-threatening eating disorder. But even if you don’t have a classic eating disorder, you might have what is called “disordered eating.”
“Disordered eating” refers to eating foods or having eating patterns that can lead to serious nutritional consequences such as deficiencies in key nutrients and electrolytes. It can compromise a person’s strength and/or stamina and lead to more frequent illness or injury. This could happen to a Warfighter, spouse, child, or other family member.
Examples of disordered eating include emotional eating, binge eating, night eating, highly restrictive dietary patterns, and avoiding foods considered “bad.” Some individuals use over-the counter products such as weight-loss supplements or laxatives; others participate in excessive exercise as a means to control weight. What starts out as a way to lose a few pounds or tone up could become a serious problem.
If you’re wondering if you practice disordered eating, ask yourself these questions:
- Do you eat in secret?
- Are you terrified of gaining weight?
- Are you always counting calories/carbs/fat grams or some other component of food?
- Do you think your identity and self-worth depend upon your weight and body shape?
- Do you exercise a lot (maybe too much) to maintain your weight or appearance?
If you answered "yes" to any of these questions, you might have disordered eating. It’s important to get help before your problem becomes more serious than you can handle. Nutritional and emotional counseling from professionals—registered dietitians, counselors, and therapists—can help. Support from friends and family is important too. See the Academy of Nutrition and Dietetics for more information on disordered eating.
The state in which athletes perform at their best is often referred to as “the zone,” but researchers refer to it as “flow.” This experience of being completely immersed in an activity involves:
- Clear goals and immediate understanding of whether actions are helping or hurting progress towards goals.
- Intense and focused concentration on the present moment.
- Merging of action and awareness.
- Absence of self-consciousness and anxiety.
- Time seems distorted (slow in the moment and fast retrospectively).
- Targeting of your attention where it is most needed.
- Challenges or opportunities feel like a stretch but still match your skill level.
- Feeling in control and prepared to face whatever happens next.
You can experience flow in myriad ways, whether you’re engaged in combat, playing competitive sports, or raising children. Flow can’t be forced, but you can set the stage for it by learning good stress management and practicing key skills through repetition.
At the Warrior Resilience Conference V in August 2013, representatives of the Comprehensive Soldier & Family Fitness (CSF2) program discussed one of the resilience-promoting skills that they teach for strengthening relationships: Active Constructive Responding.
Active Constructive Responding shows “authentic interest” where sharing creates a deeper experience for both individuals. For example, when someone shares a positive event with you, the best response is to show interest or excitement about what he or she is telling you, followed by a positive conversation about it. By doing this you can be a “Joy Multiplier.” By comparison, it’s important not to do any of these:
- Kill the joy by focusing on possible negatives about the event (being a “Joy Thief”).
- Bring up something that happened to you, turning the attention away from the other person, or completely ignore what you were told (being a “Conversation Hijacker”).
- Respond to the other person as if distracted and/or with limited interest (being a “Conversation Killer”).
Compression garments are becoming more and more popular in the sports world. Back in 2001, NBA All-Star Allen Iverson began wearing a sleeve on his arm to help with bursitis in his elbow, helping to increase blood circulation and reduce swelling in his arm. Similar sleeves are used for clinical conditions such as lymphedema, where blood circulation is poor, or to prevent blood clots.
You can find compression garments as sleeves, socks, shorts, or even full-body suits. There are various levels of compression for garments, but they all have gradient pressure, which means they’re a little tighter at the bottom of the garment and a little looser at the top to help push blood toward your heart and prevent blood from ‘pooling’ or remaining in the compressed areas. Most garments need simple measurements around your arms or legs to make sure you have the correct size.
But can these garments also impact your performance and recovery? It’s been found that compression garments do actually help with blood flow and increase oxygen to working muscles. But whether that translates into improved performance is another question altogether.
Most performance-related studies have looked at the effects of compression sleeves or socks on running. Some participants said they didn’t feel they were working as hard when wearing compression garments on their legs. While the relationship between compression garments and performance is still not clear, some researchers have suggested that this psychological benefit of lower perceived exertion might help athletes train at higher intensity. However, more research is needed to show if this ultimately leads to actual performance improvements.
In terms of recovery, more research is needed too. The effects of compression garments on muscle soreness after exercise have been mixed, but there have been no studies on the use of compression socks or sleeves for shin splints and other leg pain. They are sometimes effective at reducing the muscle soreness that occurs 24-48 hours after exercise. Relief of symptoms from wearing these garments varies from person to person, sometimes with no benefit. And it isn’t clear whether wearing these garments during recovery will improve your performance next time.
Eating disorders require psychiatric, medical, and nutritional treatments and can have serious nutrition-related health consequences for a Warfighter, spouse, child, or an entire family. The cause of eating disorders is not well understood, but military members may be particularly susceptible due to the unique stressors associated with military life, and many military members with eating disorders may go undiagnosed. Treatment of eating disorders is complex and challenging. For more information, read HPRC’s InfoReveal on eating disorders.
That “slow to wake up” feeling of grogginess in the morning has a name: sleep inertia. HPRC asked a sleep expert whether sleep inertia is a real threat to performance, and the answer may surprise you: While sleep inertia is a real phenomenon, the threat it poses to performance has never been seriously studied but probably isn’t as bad as you might think.
However, sleep inertia can be a serious issue when cognitive performance—such as problem solving and decision making—is called for immediately on waking. For example, physicians who are awakened by calls from nursing staff have been known to make serious errors. For most situations, though, it’s better to sleep (and pay down any “sleep debt”) rather than stay awake with the intent of being alert just in case you’ll be called on, our expert concluded.
If your head does need to be in the game quickly after awakening, call on some caffeine to help; it can give you the boost you need to get out of your sleep inertia. Popping in some caffeine gum when you wake up (but only when essential) can produce near-normal cognitive performance within about five minutes.
