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 oil has a sweet taste that lends distinct flavor to foods, and it contains several saturated fats—something the 2010 Dietary Guidelines for Americans suggest we eat less of. That is because eating saturated fats has been linked to atherosclerosis (“hardening of the arteries”) and increased risk of heart disease.
Although coconut oil is highly saturated, it has different types of saturated fats. One of these—lauric acid—is regularly touted as having performance benefits. Lauric acid is referred to as a “medium chain fatty acid” (MCFA), and the body processes MCFAs differently than it does “long chain” fatty acids (LCFAs). Importantly, MCFAs are digested more rapidly than long chain fatty acids, so they are quickly absorbed and available as an energy source. Some research suggests MCFAs might help to optimize and maintain glycogen stores, thus extending endurance performance. Not only that, MCFAs are less likely than other fats to be stored as fat—a plus if you’re concerned about weight control. The performance claims surrounding MCFAs and coconut oil have not held up, and claims about their weight loss benefits need more research.
The American College of Sports Medicine and the Academy of Nutrition and Dietetics joint guidelines for Nutrition and Athletic Performance indicate that MCFAs do not provide any performance benefit. To date, only two studies have shown improvements in performance. On the other hand, MCFAs have been shown to increase the body’s use of “fats” as fuels, reducing food intake, so such products may promote weight loss. There just isn’t enough information available to make any scientific conclusions.
If you choose to eat coconut oil, do so in moderation for its unique flavor and texture, because its health and performance benefits are still open for consideration.
Approximately 300 million people around the world have sickle cell trait (SCT), including approximately 9% of African Americans. It is a hereditary condition in which red blood cells are affected, but most people who have it never experience symptoms. (It is important to note that SCT is not the same as sickle cell disease [SCD]. Sickle cell disease [or sickle cell anemia] can lead to other serious clinical risks and can cause severe symptoms. Those with the SCD usually have a shorter lifespan.)
Individuals with SCT usually can participate in normal physical activity and sports, as SCT doesn’t seem to adversely affect performance. In fact, some studies have found that those with SCT excel in short-distance power activities such as sprinting and jumping.
While SCT is largely a benign condition, there have been related complications such as exertional rhabdomyolysis and exercise-related sudden death. They have been found in non-SCT individuals as well, but they occur at higher rates in those with SCT and are a “hot topic” in military, and civilian communities; the National Collegiate Athletic Association even requires screening for all its Division I and II athletes.
It has been suggested that those with SCT may be more prone to sudden death from dehydration, heat illness, and high-intensity exercise; however, these factors and the role of prevention standards, medications, and the use of dietary supplements are still being studied. In both military and civilian SCT populations, collapsing during exercise is most commonly observed during times runs and sprints within the first few weeks of conditioning. SCT Recruits who have difficulty passing the Physical Readiness Test are also at higher risk for collapse. Military leaders should be aware of safe training guidelines and take universal precautions. Effective prevention tactics include heat acclimatization, hydration, gradual physical conditioning, and addressing progressively worse symptoms early on.
All newborns in the United States are screened for both SCT and SCD as part of a public health imperative. Each military branch has its own policies regarding SCT. The Army does not screen for SCT but promotes universal precautions for all soldiers, whereas the Air Force, Navy, and Marines all screen for SCT after accession. Further testing and counseling may be done for those who are positive for SCT. If you are unsure about SCT and exercise, consult with your physician, especially if you are starting a new exercise routine.
If you’re looking to get healthier, stronger, more energetic, or less injury-prone, setting goals can help you achieve this type of optimal performance. Use the American Psychological Association’s five tips for “Making your New Year's resolutions stick“ regardless of the time of the year.
- One at a time. Doing everything at once can lead to burnout. Tackle one issue at a time by breaking your goals into pieces to build on.
- Start small. Pace yourself to go the distance. You may be eager to get started on your performance goals, but start with manageable goals and build up to the more challenging ones.
- Share. Talk about your goals and progress with family and friends, as they can be your biggest supporters. It may also help them understand what you’re trying to accomplish and might interest them enough to join you.
- Ask your buddies. Getting help is a sign of strength. It can help reduce the stress of trying to achieve your goals. If you know you are struggling with one aspect of your goal, the best thing to do is seek out advice and support. Use resources such as HPRC's Mind Tactics to get accurate information that can help you progress towards your goals.
- Don’t strive for perfection. Perfection, if not impossible, is an ever-moving target. Don’t waste your time chasing it. Performance optimization is about being at your best, not achieving perfection. How you recover from mistakes matters—don’t abandon your goals. Learn from your mistakes instead and get back to your goals.

Optimism is a hallmark of resilience, and being optimistic can enhance your performance. Having a positive outlook can also help you harness your mental and physical strength to deliver your best performance, no matter the conditions. Whether you’re facing physical, mental, or emotional challenges, learn how to shift your thinking from negative (pessimistic) to positive (optimistic), and see how an optimistic perspective can help you achieve a greater outcome. For help on how to accomplish this, check out HPRC’s "Reframe your thoughts for peak performance."
Pentagon scientists are hoping to build special gear designed to turn divers into veritable Aquamen (and Aquawomen). Although it’s still in the research phase, the new system would protect divers from the adverse effects of diving too deep or surfacing too fast. Sensors would read and adjust to a diver’s physical signs as well as help control levels of nitric oxide to prevent the decompression sickness known as “the bends.” When a diver ascends too quickly, bubbles form inside the body, which can block the blood vessels in the spinal cord and disrupt the nervous system. It can be very painful and can lead to joint pain, paralysis, and even sudden death if a diver is not careful.
The new diving gear will be a portable and versatile system that can potentially serve for use in other special operations as well as for civilian divers. This system will have to be designed for the most extreme combat dive profiles, which sometimes require a 35,000-meter free-fall from an aircraft, diving 200 feet below the surface for at least two hours, surfacing, and immediately diving again, followed by continued protection after being picked up in an unpressurized aircraft. This is one of DARPA’s most recent Small Business Innovation research proposals for 2013.
Individuals who have incorporated the recommendation of 10,000 steps a day into their lives have seen positive changes in their health, including weight loss, lower blood pressure, decreased risk for diabetes, lower cholesterol, and better psychological health. Many organizations, including the American Heart Association, recommend walking 10,000 steps—or approximately five miles—a day for optimal health. Having a goal of 10,000 steps will get you, your family, and friends moving more every day, which reduces health risks.
A pedometer is an easy way to start counting your steps! Turn it into a fun, inexpensive challenge for your family or colleagues—see who can get the most steps in a day or week. It might be harder than you think. Here are some tips from the American Heart Association to help you get to 10,000.
Researchers have long been interested in meditation and its potential benefits. A recent study found that regular meditation practice of 20 minutes a day has a lasting effect on how your brain processes emotions. This suggests that meditation could potentially help your brain handle stress, anxiety, and depression, and possibly other feelings. For those individuals dealing with relocation, deployment after-effects, chronic stress overload, recent family changes, or new training assignments, having a strategy to improve your resilience and help process the expected extra doses of emotions can be helpful.
