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.
Think of a goal that you’ve been working for lately or that you’re about to go after. How about all those New Year’s resolutions? Do you know why you want it? In other words, what’s your motivation? Do you simply love what you’re doing, or is there a reward you are pursuing?
Being clear about what motivates you can help fuel your motivation with intention. For example, if you’re a runner, maybe you love the feeling of pushing yourself hard with training runs. On the other hand, maybe it’s the end result—the accomplishment—associated with completing another marathon that’s the fuel to keep you going or even push you to the next level.
There isn’t one right form of motivation, and your motivators might be a mix of little steps and big outcomes. Remember to enjoy the steps along the way; they can make the experience more enjoyable. But sometimes remembering your ultimate goal can help you persist on days when you’re just not feeling it.
Often when you’re pursuing a goal, you’re part of a larger community, and you may find that just being involved is motivation itself because of the people you meet, the places you see, or the experiences you have along the way! It’s true what they say: The journey matters.
Have you ever wondered how different people’s perceptions of the same thing can be so drastically different? Take exercise, for example. You know it’s good for you, and most people should be doing more of it. Yet when asked, some people will say they love to exercise, while others see it as an overwhelming and impossible task. Our perceptions say a lot about what we value, how we’re feeling, and what we desire, which in turn affects motivations, actions, and even physical performance.
You probably find that the goals that seem more in reach are more desirable (for example, money, food, or a finish line) than the ones that seem further away. For example, when you’re at the end of a race, and you can see the finish line in front of you, you’ll probably estimate that the finish line is closer to you than it really is. Whether or not the goal is actually closer, believing that it is triggers excitement and effort towards achieving these goals.
That’s all well and good if you’re already out running that race, but sometimes getting off the couch is the hardest thing to do when you’re out of shape. Runners who are less fit and less motivated estimate distance to a finish line as being farther than do runners who are fit and more highly motivated. So even if you want to get in shape, sometimes your poor fitness can affect your perception of being able to achieve your fitness goals.
While negative perceptions might make it harder to get in shape, this doesn’t mean you can’t get in shape just because you’re less fit. Keep your eye on the prize! Exercisers who focus on an end goal and ignore the distractions around them perceive their goal as being nearer and actually perform better; most importantly, they don’t consider the exercise as difficult.
So, if you see your goals as being closer to you in your mind, you will have something to look forward to. This “prize” could be anything. It could literally be the finish line; it could be the next milestone on your route, such as the building at the end of the block; or it could even be a post-race reward, such as a healthy post-workout smoothie. Remember, some goals are harder to achieve than others, but you can stay the course by imagining what is coming and keeping the self-talk positive. This will help keep your motivation high and the prize within reach.
It’s officially “holiday season,” and maintaining your fitness can be a challenge. You might find yourself socializing and eating more, with less time (and motivation) to exercise. Get your workout routine into the holiday spirit too—without having to sacrifice a lot of time.
- Take the Guard Your Health Fitmas Challenge! Each day for twelve days, commit to doing one of these exercises.

Is it safe to exercise when I’m sick? This is a common question, especially from people who have strict workout schedules and aren’t likely to let the sniffles get in the way of their physical fitness. Benefits of exercise include weight control, improved mood, more energy, and better sleep. What’s more, just 30 minutes of regular exercise three or four times per week can boost your immune system and improve overall health, helping to keep those colds at bay.
Moderate exercise while you’re sick can be safe and in certain cases may actually improve symptoms (such as relieving congestion and increasing energy). But first you need to determine “how sick is sick.” You can figure this out by using the “neck rule.” If you have symptoms above the neck—including sore throat, nasal congestion, sneezing, or watery eyes—then moderate workouts can continue. If symptoms are below the neck—including cough, fever, fatigue, or body aches—then rest is in order until the symptoms are gone. You can also use your temperature to determine whether exercising is okay. If you have a temperature of 101°F or higher, moderate or vigorous exercise is not wise because of the risk of heat-related illnesses and dehydration.
Ultimately, the decision to exercise when you’re sick is up to you. If you’re too weak and fatigued to get out of bed, exercising may not be the best thing to do at that time. However, if you have symptoms of a cold and your temperature is below 101°F, light to moderate exercise may be beneficial. You should consider seeing a doctor if your symptoms don’t improve or get worse.
Look around you. How many people do you see looking down at their smartphones? Are you reading this article on your phone or tablet? Most people look down at their phones while reading or texting. The problem with this posture it can be a major pain in the neck—literally. Doctors and researchers are calling it “text neck,” and they’re saying that this poor posture while looking at your phone is causing early wear and tear to the spine. The human head weighs about 10 to 12 pounds. Looking straight ahead doesn’t add any strain to your spine, but as you tilt your head forward, the weight of your head begins to increase the strain on your neck and spine. Even a slight, 15-degree angle increases the weight on your spine to 27 pounds. Looking down at 60 degrees? That’s about 60 pounds. Think about carrying a couple of 30-pound ammo cans around your neck for several hours a day.
To limit your risk for text neck, look down at your device with your eyes, not your head. Better yet, hold your device up to eye level. Be aware of your posture and try adding daily exercises that strengthen your back, neck, and shoulders.
Training on a treadmill versus running outside – is there a difference, besides the scenery? Is one better than the other? These are frequently asked questions in the running world, especially when the weather makes outdoor running a challenge. Researchers provide a short answer: Training on the treadmill and “overground” running are not the same.
If you’ve experienced treadmill running and find yourself more tired afterwards than you would on an outdoor run, you’re not alone. Studies have found that athletes actually run slower on a treadmill than their normal pace outside, although they perceive treadmill running as being more exhausting. In other words, even though it feels more difficult, treadmill running is usually less intense and less physically challenging than running outdoors.
However, running indoors can be helpful if you’re recovering from an injury since running on a treadmill is easier on your joints than running outside on concrete or even grass.
Bottom line up front, you do run differently on a treadmill than you do outside, even if you don’t realize it. If you’re training for an outdoor race, ideally you should run most of your training miles outside. When you want to or need to run indoors on a treadmill, set the incline at 1–2% to increase your exertion level to more closely replicate your outdoor runs.
If you do decide to run outside during a cold spell, take a look at our article with tips for staying safe and the many resources where you can find more ways to keep warm and hydrated even in frigid weather. Remember: Whether you stay in or venture out, any exercise is better than none!
The Female Athlete Triad is a condition that commonly affects physically active girls and women, especially those involved in activities such as dance or gymnastics that have a heavy emphasis on weight and physical appearance. The Triad is characterized by energy deficiency, amenorrhea (menstrual disturbances), and osteoporosis (bone loss). Poor eating habits combined with high-intensity exercise can cause energy deficiency, although energy deficiency can occur even without disordered eating. Over time, estrogen decreases and causes menstrual cycles to become irregular or stop completely. However, estrogen is also important for building strong bones, so when estrogen levels drop, bones become weaker and osteoporosis can develop.
Female Warfighters can be at risk for developing the Triad if they don’t get enough calories and if training is too intense. In the short term, lack of energy will lead to fatigue and difficulty concentrating—an equation for poor performance. Continued energy deficiency, though, can lead to muscle loss and decreased strength, putting you at higher risk for injury. Then, even when you’re training hard, your performance may fail to improve or actually worsen.
You can prevent the Female Athlete Triad easily by focusing on your overall health and nutrition rather than your weight. Food is the fuel that helps you to perform at your best.
It seems that just about everyone is a runner these days, and it’s an essential part of being a Warfighter. Since 1990, the number of road race finishers in the U.S. has more than quadrupled. Participation in the largest road races has increased 77% in 14 years! More runners means more who need to learn about running injuries.
