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.
Coconut water, the flavorful liquid found in young green coconuts, has become a popular drink. It is often promoted for a variety of ailments—from curing bad skin to resolving hangovers. But coconut water is also touted as a fluid replacement alternative. For this reason, some Warfighters choose coconut water over sports beverages because coconut water is “natural” and contains carbohydrates and key electrolytes such as sodium and potassium. However, not all brands of coconut water are created equal. In fact, they can vary considerably in terms of their nutrient content, so read product labels to be sure you’re getting the right amounts of nutrients you need for optimal performance. In addition, many kinds of coconut water contain fruit juice for flavor, which can increase the sugar and calorie content of the drink.
One of the biggest appeals of coconut water is its naturally high potassium content. While the potassium content is high, the amounts of carbohydrate and sodium in coconut water are sometimes very low, and individuals who participate in prolonged, vigorous exercise (longer than an hour) may need more carbohydrate and sodium for proper hydration. For more information about hydration needs, see HPRC’s article on fluids and exercise.
For periods of exercise less than one hour, water is always your best choice—about 3–8 ounces every 15–20 minutes. But for longer periods of exercise, sports beverages are a good choice because they are specially formulated to replenish carbohydrate, sodium, and potassium lost during extended and/or vigorous physical activity. If you choose sports beverages, drink 3–8 ounces every 15–20 minutes to stay hydrated. Again, be sure to read the product label to make sure your drink has what you need, and nothing more. For more information about proper fueling, read An Athlete’s Guide to Nutrient Timing.
And what about that coconut water? There simply isn’t enough evidence to support the use of coconut water as a remedy for any condition. And although it’s a tasty beverage, know what’s in it so you can replenish what your body needs—no more, no less.
Phentermine, a prescription drug used for weight loss, is similar to amphetamine. So, will it cause you to pop positive on your military drug test? Is it ok to use as long as you have a prescription? Read the OPSS FAQ to find out answers to these questions.
OPSS has other FAQs to help answer questions about the safe use of dietary supplements. And the OPSS High-Risk Supplement List will be available soon, so check the OPSS homepage often for up-to-date information.
Many of us have seen foods labeled as organic, but most people don’t know what that means. In order to be considered organic, foods must be certified by the United States Department of Agriculture (USDA) and meet certain standards. Generally, organic foods must be produced without the use of any artificial fertilizers, pesticides, growth hormones, antibiotics, sewage sludge, or genetically modified organisms. As a result, organic foods have become quite popular.
Because of the differences in production, organic foods tend to be more expensive than conventional foods. For example, the average price of a gallon of regular milk is $2.89, but the average price of a gallon of organic milk is $5.99. That’s more than double the cost, which may not be affordable for many people. For military families who prefer to buy organic foods, discounted prices may be available at their local commissary. Ask grocery stores and wholesale stores about military discounts and coupons. For those who qualify, the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) allows organic fruits and vegetables to be purchased with cash-value vouchers. The eligibility of other foods is state-dependent, and each state’s approved food list can be found on USDA's WIC page.
The price difference between organic and conventional foods is clear, but the benefits of choosing organic are not as obvious. Organic foods are thought to be better for the environment and our bodies. However, from a nutritional standpoint, there is not enough evidence to suggest a clear benefit to purchasing organic foods over conventional foods. If pesticides are your concern, visit the Environmental Working Group website to learn more.
So, the next time you’re trying to decide between organic and non-organic, remember that nutritional differences don’t need to be a major factor in your decision because there don’t appear to be any. A diet rich in fruits, vegetables, and whole grains is beneficial no matter which option you choose.

Whether on the playing field or on a mission, of course you want to succeed. Dreaming of positive outcomes can drive you to train hard. But you may have noticed that when you only focus on the outcome, you’re distracted from the important ingredients for success. Your successes will unfold more easily if you develop goals centered on what’s in your control rather than how you compare to others. Learn more about setting different kinds of goals in this HPRC article on sport psychology goals.
It’s almost time for the Warrior Games in Colorado Springs! Athletes and teams from each branch of service have already qualified in their respective trials and are set to compete from 28 September through 6 October at the U.S. Olympic Training Center in Colorado. The Warrior Games give wounded service members and veterans an opportunity to compete in adaptive sports. For some, this is a continuation of their competitive careers; for others, it’s a new experience and part of the healing process. If you’re in the neighborhood, stop by to cheer on the athletes—admission is free! Semper Citius, Altius, Fortius!
“Sport psychology” uses the principles of psychology to help optimize performance in athletics. These concepts can be applied to just about anybody (including Warfighters) in any setting where performance matters, so sport psychology often gets dubbed “performance psychology.” Regardless of the name, this focus on the mental aspect of performance fits into a holistic approach to Human Performance Optimization (HPO).
A major focus of sport or performance psychology is mental skills training, building a “toolbox” of mental skills based on sport science and clinical/counseling psychology techniques. These scientifically based methods can be applied to Warfighter performance too. Some basic tenets of performance enhancement within military and sport settings include maintaining high awareness, motivation, and self-control, either by reducing how “amped up” you get or by learning to interpret these feelings as either meaningless or helpful to performance. A well-trained Warfighter can either calm down and think, “I’ve got butterflies, but no big deal,” or “I am psyched up and ready!”
Mental skills are important, but they’re only part of a performance psychology package. Performance psychology looks to fix or improve performance by: 1) training skills to proactively address problems, 2) improving resilience to avoid problems in the first place, 3) enhancing performance, and 4) reducing stigma around getting help with problems after they’ve appeared. In applying performance psychology to Warfighters, training is customized to meet the needs of specific groups, focused on real-life applications, and taught in a way such that skills are learned for optimal functioning both at work and at home. HPRC endorses holistic training programs that include performance psychology, such as One Shot One Kill (OSOK), a platform that helps Warfighters to customize their own systematic training.
Roughly one in three children in the United States is considered to be overweight or obese. Children who are obese are more likely to be obese as adults, which can put them at risk for diabetes and other health conditions. The month of September is devoted to raising awareness about childhood obesity, with a focus on prevention.
We Can!® (Ways to Enhance Children’s Activity & Nutrition) is a national movement sponsored by four National Institutes of Health organizations to help children from ages 8 to 13 remain at a healthy weight. The website has specific information and educational resources geared toward the individual, family, and organizations. See HPRC’s Family Nutrition resources for more information and this HPRC card for easy reminders. For more about the exercise aspect of overcoming obesity, check out the Family & Relationships article from earlier this month.
The United States Air Force will be 67 years old on September 18th. It is the youngest branch of the United States Armed Forces, owing its existence as a separate branch to World War II’s demonstration of the significance of aviation. In 1947, President Truman signed the National Security Act that created USAF. Before that, military aviation was under a division of the Army, which—remarkably—formed the Aeronautical Section of the Signal Corps in 1907, only seven years after the first piloted aircraft took flight. The Army procured its first powered aircraft in 1909 and deployed its first aviation unit in 1913.
True to its roots, USAF has always embraced the leading technology of air, space, and cyberspace. Its X-37B space plane, currently in the news, is USAF’s latest step in going “where no one has gone before.”
For some people, eating certain foods can cause serious allergic reactions, even death! The most common food allergens are milk, eggs, fish and shellfish, tree nuts (such as almonds, walnuts, and pecans), peanuts, wheat, and soy. Other food allergies are possible, so it’s important to read food labels for ingredient information if you are at risk. Click here for more information.
