How am I doing? Ask my computer…

Technology can help us be more aware of how we think and even how we feel. It is all still evolving, but these advances are promising for optimal Warfighter training and health.

Good decision-making is crucial to mission success for any Warfighter. Advancements in technology can help build awareness of how people think (that is, how they remember and evaluate information) and even how they feel (recognizing “gut feelings” and what drives them). “Affective computing” and “wearable sensing” are no longer science fiction. Special bracelets or other articles of clothing can sense one’s needs in terms of exercise, diet, and sleep and can even be programmed to communicate physical or emotional needs to others. Optimal training can occur when emotions facilitate learning rather than impede it. And it doesn’t stop with training; “e-health” applications for mental health, delivered via smart phones or other small mobile devices, are promising, especially as the technology continues to advance.

Sleep and the Warfighter

Sleep is essential for optimal performance. Especially Warfighters, though, it can be hard to come by. Lack of adequate sleep, called “sleep debt,” can result in reduced mental and physical performance (see HPRC's "The impact of sleep loss on total fitness"). Use HPRC’s “Sleep & Warfighters” infographic to learn how sleep impacts your health and performance, as well as tips to get your best rest.

A holistic approach to performance

Check out the customizable “One Shot One Kill” (OSOK) performance enhancement program to jumpstart your performance.

Wanting some holistic strategies to enhance your performance? Check out the “One Shot One Kill (OSOK) Performance Enhancement Program” that shows Warfighters how to set up and manage their own performance-enhancement system. OSOK is designed not only to enhance performance but also to jumpstart Warfighter resilience. It builds on the skills that Warfighters already possess and then teaches new ones as needed.

There are two ways you can use OSOK: as an individual through “OSOK Solo” and as a unit/group through “OSOK-IP Unit.” Both highlight “10 Rules of Engagement” and provide seven core modules: Controlled Response, Mind Tactics, Performance-Based Nutrition, Primal Fitness, Purpose, Code, and Recharge. OSOK also provides self-assessment forms so you can track your progress over time.

Marine Corps Embassy Security: New year, new requirements

If your goal is to serve in the Marine Corps Embassy Security Group, then you should know about the new requirements and fitness standards.

On January 14, 2014 the Marine Corps released MARADMIN 010/14, which details the new requirements for the Marine Corps Embassy Security Group. Marines who want to travel the globe and provide security services for U.S. embassies and consulates now have to meet new, revised standards. Among other things, Marines must be at least 64 inches tall so they can adequately view all areas from Post One (point of entry control at diplomatic posts). In addition, physical fitness standards have changed: Marines will have to achieve 1st Class PFT scores. If you haven’t yet achieved this level of fitness, we have some tips. First and foremost, for optimal fitness, be sure to train smarter, not harder.

Garbage in, garbage out

HPRC Fitness Arena: Nutrition, Total Force Fitness
When it comes to optimizing your performance through nutrition, it’s important to choose high-quality fuels and nutrients.

The phrase “Garbage in, garbage out” was coined first by computer experts back in the 1960s. Since then, the phrase has gained a wider usage—even to the world of performance nutrition. Providing your body with high-quality fuels and nutrients is crucial to optimizing your performance. Like the poorly fueled runner in HPRC’s video, you’re likely to find that a diet of high-fat or sugary foods and drinks (“garbage in”) produces less than optimal results (“garbage out”). Instead, choose wholesome foods such as lean meats and fish, fresh fruits and vegetables, whole grains, and low-fat dairy products, which provide high-quality fuels and nutrients.

“Amped up” the right amount to perform your best?

Filed under: Mind, Performance, Stress
For some tasks, you can optimize your performance by being “amped up” just enough but not too much.

Whether you’re falling asleep or too “amped up,” you probably aren’t performing your best. Depending on who you are and what the task is, some middle ground is generally going to be best.

With simple tasks that require little conscious thinking, your reaction time is probably at its best around 60-70% of maximum heart rate (see HPRC’s article on aerobic conditioning), but response times for bigger bursts of movement improve if you’re more amped up. For example, you may be able to pull the trigger of your weapon fastest when you’re at 60-70%, but reaching for your weapon in the first place may be quickest if you’re at 90%. Keep in mind that this may not apply to more complicated tasks that involve rapid thinking, such as distinguishing a “friendly” from a “non-friendly” when someone is disguised.

There are two basic ways to get yourself amped up: physical activity and anxiety. Physical activity can happen through an intentional warm-up or even on its own because of the demands you are facing. If anything, you might find yourself needing to calm your body down. The same goes for anxiety. There’s the “butterflies-in-your-stomach” kind of anxiety and the more panicky “Darn! What do I do now?” kind. A little bit of the butterflies kind can be helpful, but again, it’s good to learn how to calm down and find middle ground!

Performance Strategies for injury prevention

An ounce of prevention is worth a pound of cure. Check out our performance strategies for preventing common military injuries.

Injury prevention is critical in maintaining optimal performance and operational readiness. Ankle sprains, knee pain, and back pain are very common injuries in the military. Take the time now to protect yourself from injury, and you’ll be glad you did later. Read our performance  strategies to help fend off common military and athletic injuries, compiled from our recent injury prevention series of posts.

A big name for a common knee problem

One very common cause of knee pain has a fancy name, but avoiding it can be quite simple if you follow some important advice.

Chondromalacia is a knee problem that can have a number of different symptoms, including pain. It can your ability to exercise, but even more problematic is that it can interfere with your ability to meet the demands of your military duties.

Here’s the basic rundown on chondromalacia: In a healthy state, the kneecap has soft cartilage beneath that allows the bone to glide smoothly against the other bones of your knee joint. When the smooth surface wears away, the back of the kneecap becomes rough and rubs the other bone surfaces, causing pain. The key to avoiding this condition is maintaining that smooth surface.

According to the American Academy of Orthopaedic Surgeons, muscle weakness, imbalance, or tightness in the thigh muscles can contribute to chondromalacia. It’s important to maintain strength in your quadriceps and hamstring muscles; follow a strength-training program to develop and maintain strong muscles. Also, make sure that you have enough flexibility in your quads; if the muscles and tendons are too tight, they can force the kneecap to move or “track” incorrectly in the natural groove of your knee joint. If you do a lot of running, make sure your footwear isn’t old and worn, because the shock-absorption of shoes decreases as they age. When it comes to knee pain, an ounce of prevention is worth a pound of cure. Strengthen and stretch your muscles, and you’ll be on your way to keeping your knees ready for action.

Get into a state of flow

HPRC Fitness Arena: Total Force Fitness
You’ve heard of being “in the zone,” but do you really know what it is? Find out what is involved in getting yourself into this optimal state of flow.

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.

For more information you can use to help you get in the zone, check out HPRC’s Stress Management and Mind-Body Skills sections.

Don’t let your performance suffer from grogginess

Learn about whether sleep inertia impacts your performance.

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.
