Spare your back when moving

Here’s a reminder about how to handle heavy objects properly and protect your back when loading your moving truck during PCS.

Service members and their families relocate a lot, and moving to a new home is hard enough without adding injury. Here are some tips on how to properly handle heavy objects such as moving boxes and furniture, and how to take care of yourself if you do sustain an injury:

  • Wear less-restrictive clothing such as looser-fitting pants or workout clothes.
  • Wear closed-toe shoes.
  • Take breaks when necessary. Stretching and reassessing your mechanics can help you maintain proper posture when lifting. HPRC has tips on how to maintain flexibility and remove tension in your body.
  • The U.S. Army has fact sheets on Lifting Techniques for handling heavy objects and How to Safely Perform Pushing and Pulling Tasks.
  • Remember to keep your core tight, and use your leg muscles rather than your back to lift heavy objects.

The best way to prevent back injury is to strengthen your back and core muscles. The National Institutes of Health (NIH) has suggestions and exercises to help build your back.

If you’re sore from all the lifting or think you may have pulled something, you can treat the pain with ice and rest—and perhaps an over-the-counter pain reliever—for the first 48 hours. Follow NIH guidelines on how to further treat your back pain if it’s acute. However, if the pain persists, consult your doctor to rule out a more serious back problem or injury before you do any more heavy lifting. If all seems well, consider core-strengthening exercises to support your back. Another option is a yoga class to relieve your pain, build your muscles, and return your back to normal function.

What should I look for in sports drinks?

Sports drinks are popular products for fueling and hydration during workouts. Learn about what your sports drink should contain and how they stack up to nutrient recommendations for performance.

Sports drinks that contain electrolytes and carbohydrates can be essential to performance by replenishing what is lost during activity, mostly through sweat. For activities less than 60 minutes, water is the best drink to replace lost fluids. If your exercise session or mission exceeds 60 minutes, then sports drinks can be helpful. Follow HPRC’s guidelines for maintaining important nutrients such as fluid, carbohydrates, sodium, and potassium during activity to keep well hydrated and on top of your game. Read more here.

Can meditation boost your immune system?

HPRC Fitness Arena: Mind Tactics, Total Force Fitness
Meditation may improve your immune system, help you feel better, and help you use fewer sick days.

Not only can meditation help with stress, it may even boost your immune system and reduce inflammation. In fact, research has found that people who have been in a structured mindfulness program actually had fewer sick days compared to those who didn’t meditate. Even when you’re sick, meditation may actually help you feel better (and happier) in spite of lingering symptoms. And although meditation doesn’t seem to help the elderly to the same extent, it can still help some.

Aviation and hypoxia

HPRC Fitness Arena: Environment, Total Force Fitness
Filed under: Aviation, Flight, Hypoxia
Hypoxia in aviation is a real threat. Learn the signs and symptoms to recognize it.

Hypoxia, or insufficient oxygen supply to the body, is a stress factor associated with high altitude in aviation. It’s caused by low oxygen levels and decreases in partial pressure. Flight above 10,000 feet is dangerous and restricted without supplemental oxygen, and even the best oxygen and pressurization systems fail sometimes. Above 10,000 feet, an aviator’s “Time of Useful Consciousness” (TUC) begins; this means that you’re going to start having problems focusing, reacting, and making decisions. At 15,000 feet your TUC is around 30 minutes, at which point you’re more likely to be unconscious than not. At 22,000 feet it’s only 5–10 minutes, and by 28,000 feet it can be as fast as 3 minutes! Look out for these signs (what you can see in somebody else) and symptoms (what you can notice in your own body):

  • Cyanosis (bluing of the fingertips or lips)
  • Headache
  • Decreased reaction time
  • Impaired judgment
  • Unexplained happiness/euphoria
  • Visual impairment
  • Drowsiness
  • Lightheaded or dizzy sensation
  • Tingling in fingers and toes
  • Numbness

If you notice any of these signs or symptoms, remember to find the emergency oxygen, use it, and land safely!

Get good: Practice like you mean it.

There’s no easy path to becoming skilled in work or play. You need deliberate practice to consistently perform your best.

To be good at something, you can’t avoid hard work. It often requires 10,000 hours of “deliberate practice” to become an expert in a profession, sport, game, or other skill. You can’t just go through the motions of practice sessions. You need to engage in “deliberate practice” in which you’re highly focused on mastering specific skills in complex conditions.

The most impressive performances require talent, but even the most talented people have to deliberately train skills to reach the highest level of capability and performance and then to maintain that level.

To develop and maintain your own talent, try the following:

  • Train your body, mind, and emotions with specific skills that are most related to what you want to achieve.
  • Have a sense that “I can do this.”
  • Cultivate the ability to cope with the emotions of disappointments and setbacks along the way.
  • Listen to feedback from others (a commanding officer, coach, or mentor) and put it into practice.

The video below (source) shows one example of where deliberate practice matters. Doctors who deal with a “Code Blue” heart failure situation hope for the best, but they consistently (and deliberately) prepare for the worst.

Got (chocolate) milk?

HPRC Fitness Arena: Nutrition, Total Force Fitness
It’s important to replenish your body after working out. Chocolate milk provides essential nutrients and is inexpensive, easy to find, and tasty.

Need a great post-workout beverage? Try drinking a glass of chocolate milk within 45 minutes after exercise to replenish glycogen stores and repair muscles.

Why chocolate milk? One 8-ounce glass of chocolate milk provides about 200 calories and the right ratio of carbohydrate to protein. It also provides electrolytes such as potassium and sodium, along with essential vitamins and minerals such as vitamin D and calcium in an easily digestible liquid form. And even better, it’s inexpensive, readily available, and tastes good! But be sure to choose heart-healthy low-fat versions.

For those who are lactose intolerant or allergic to dairy products, or for those who simply prefer a plant-based diet, fortified chocolate soymilk is a great alternative (but note that almond, cashew, and rice milk are not as high in protein).

Separating fact from fiction online

Filed under: Education, Nutrition
There are thousands of websites that report on nutrition topics, tips, and trends. Which ones are questionable, and how do you spot the reputable sources?

How do you tell the good from the bad online? The Internet can be a great resource when you want to learn about a health condition or nutrition topic. But some websites provide nutrition-related information backed by sound research, while others base their information on myths and half-truths. HPRC offers some tips on what to avoid and what to look for instead to help you find accurate health and nutrition information on the Internet. Read more here

The foundations of Total Force Fitness

Get back to basics with the foundations of Total Force Fitness: health, resilience, and performance optimization. What are they and how do they go together?

Have you heard the terms “resilience” and “Total Force Fitness,” but you’re not quite sure what they mean or where they fit into the health and performance picture? Read on.

Your health is the foundation. The 2010 article "Why Total Force Fitness?" states, “nothing works without health.” Health is not just physical and not just something to worry about when you’re sick. Health is a combination of physical, mental, spiritual, and social well-being and includes practices that promote wellness in addition to those that help you recover from sickness or injury.

Resilience is next. Resilience is the ability to bounce back—or even better, forward—and thrive after experiencing hardship. It is not the ability to completely withstand hardship but rather the ability to come back from it and grow stronger through the experience.

Next is human performance optimization (HPO). Unlike resilience, which typically requires the experience of hardship, HPO involves performing at your best for whatever goal or mission you have (whether that is your PT test, a combat mission, or raising children). It goes beyond simply resisting challenges; it means functioning at a new optimal level to face new challenges.

Health, resilience, and optimal performance are the foundations of Total Force Fitness, which is defined in the “Physical Fitness” chapter of “Total Force Fitness for the 21st Century” (see link above) as a “state in which the individual, family, and organization can sustain optimal well-being and performance under all conditions.” Being totally fit requires a holistic approach—that is, an approach that doesn’t focus on just one aspect alone such as nutrition or physical fitness, but on multiple domains of fitness. It means attending to your mind (including psychological, behavioral, spiritual, and social components) and your body (including physical, nutritional, medical and environmental components). In order to achieve Total Force Fitness, these factors come together to enhance your resilience and/or performance.

This is where HPRC can help you on your quest for total fitness. By visiting each of our domains—Physical Fitness, Environments, Nutrition, Dietary Supplements, Family & Relationships, and Mind Tactics—you can get evidence-based information on a variety of holistic topics to help you achieve and sustain total fitness. But remember that total fitness is a life-long process that will ebb and flow. And it isn’t just about you; your loved ones are an important piece of the picture, too.

The dirt on diatomaceous earth

Diatomaceous earth is promoted as a “cure-all,” but is there any truth behind the claims?

Diatomaceous earth (DE) is a powder composed of fossilized algae called “diatoms.” Diatoms are single-celled organisms found in bodies of water, and DE is used commonly for various reasons: 1) a natural insecticide; 2) an anti-caking agent; and 3) a clarifier for wine and beer. However, some people add food grade DE to their food and beverages because DE is a rich source of silicon dioxide. Silicon is a chemical element that occurs naturally as silicon dioxide in many foods, such as whole grains and vegetables.

Proponents of DE suggest that the high silicon dioxide content helps with weight loss, detoxification/cleansing, energy levels, joint pain, teeth and gums, cholesterol and blood pressure, and food absorption. Consumers and some retailers of DE supplements also claim that its abrasive (scratchy/rough) and absorptive properties improve digestive health by ridding the intestines of bacteria and parasites as well as regulating bowel movements.

There is not enough research to support these claims, and the biological role of silicon in humans is uncertain, so there is no recommended intake or DRI (Dietary Reference Intake). According to Natural Medicines Comprehensive Database, silicon is safe to consume in amounts commonly found in foods, but insufficient scientific evidence is available for its effectiveness and safety as a dietary supplement.
