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.
The dietary supplement and fitness industries are filled with sport drinks, powders, bars, pills, gels, footwear, clothing, and an array of devices all claiming to provide you with a competitive advantage, whether it be improved performance or enhanced recovery. With the ever-growing popularity of team and individual sports, professional and recreational athletes of all ages are an easy target for these claims. But how many of these claims are backed by evidence-based research?
A recent report now reviews the quality of evidence behind the claims of improved sports performance made by advertisers for a wide range of sports-related products, including sport drinks, supplements, footwear, and clothing. The team identified 431 performance-enhancing claims for 104 products advertised in more than 100 general, sport, and fitness magazines in the UK and U.S. for a single month in 2012. They found that more than half of the advertisements and their associated websites provided no evidence to support the claims of enhanced sports performance. Only 146 references were found, and only 74 of these met basic criteria for research quality and almost all of the 74 were found likely to be biased or lacking scientific objectivity. Only three studies were rated as “high” quality and probably unbiased. Such lack of evidence makes it very difficult for consumers to make well-informed decisions about using performance-enhancing sports products.
This review makes it clear that many of the claims made for sports and fitness products lack reliable evidence to support them and that more and better studies are needed to help inform consumers. In the meantime, consumers should be cautious when reading claims of enhanced performance and recovery and always remember that “true” evidence-based results mean that a substantial number of independent research studies have been performed, with findings that clearly support the claims made by advertisers. Presently, there is still no substitute for sound physical conditioning and nutrition practices.

Giant hogweed—no, it’s not an ingredient in one of Harry Potter’s potions; it’s a large poisonous plant that started to bloom in the northeast and northwest areas of the U.S. and parts of Canada earlier this month. If you’re out for a ruck march through the woods and you come across this plant, do not touch it. The sap can cause irritation and burns to your skin and perhaps blindness if it gets into your eyes. If you do happen to come in contact with it, be sure to wash your skin with soap and water and keep the area out of the sunlight for 48 hours. Giant hogweed can grow 14 feet or higher. It’s characterized by large leaves and white, umbrella-shaped flower clusters at the top of the plant. It may be difficult to distinguish from other non-poisonous plants such as cow parsnip, so err on the side of safety if you’re not sure. You can read more about identifying invasive species in your area from the U.S. Department of Agriculture.

Pre-deployment can mean a number of things to a Warfighter, from intense training or drills to saying farewell to family and friends. Preparation for deployment can be over months or at a moment’s notice with little or no time to settle your affairs. It’s important to have a checklist and contact list ready to use prior to your departure so you’re ready, whatever the scenario.
Having your personal finances in order should be a high priority. Options for being ready might include contacting a financial advisor, setting up automatic deposits and withdrawals, creating a monthly budget, checking into over-withdrawal options, adding a close friend or family member to your account to act in your absence, and reviewing your financial information and account numbers with a responsible person. Once all your financial ducks are in a row, your finances will be easy to maintain.
Your checklist should also include items such as legal documents, personal property review, auto and home insurance and maintenance, medical information, and international phone coverage.

Lyme disease is a serious concern for those who spend a lot of time in heavily wooded areas and a especially for the DoD. It’s common in the United States and around the world and is caught from the bite of two different species of ticks—the deer tick and the western blacklegged tick.
After spending time in wooded or grassy areas, check yourself all over, including your back (enlist a friend or a mirror to help). The early removal of a tick that’s attached to you is key in preventing Lyme, since the tick must be attached for 24-48 hours in order to transmit the bacteria that cause this disease. Ohio State University conducted a study using different tick-removal tools and concluded that all three tools were effective—and confirmed that early removal is more important than the type of tool that is used. The Centers for Disease Control provides easy-to-follow tips on tick removal using just tweezers.
If you know you’ve been bitten by a tick, or begin to notice symptoms such as a bullseye rash (an early sign of Lyme infection) at a bite location, fatigue, chills, fever, muscle aches, or swollen lymph nodes, you should to see your doctor. Blood tests can be used to confirm whether the symptoms are from Lyme disease. If left untreated, more severe symptoms can occur, such as loss of muscle tone in the face (called Bell’s palsy), severe or shooting pain, and heart palpitations. A typical successful treatment includes a course of antibiotics, but there can still be lingering symptoms, called chronic or post-treatment Lyme disease syndrome. When it comes to Lyme disease, the best offense is a good defense. Some tips for prevention:
- Wear your military uniform properly. This can help to prevent tick bites since long pants, long sleeves, and pants that are tucked into boots minimize exposed skin.
- Use insect repellents such as DEET or Permethrin.
- If you are in a wooded area, avoid tall grasses and brush. If this isn’t possible then be sure to follow tips #4–7 below as you are able.
- Perform a thorough skin check—especially of the hair and base of the skull at the hairline.
- Shower within two hours of being outside. This can help wash off ticks that are still crawling on the skin.
- Examine gear and pets for hitchhiking ticks.
- If you have access to a dryer, put your clothes in it for an hour on high heat to kill any ticks.

Do you know that many kinds of chewing gum—including the gum in MREs—contains a sugar sweetener called “xylitol”? This natural sweetener can be good for your teeth and gums! Xylitol has been found to offer preventive dental benefits, including reduced bacteria and acids that cause cavities and significant decreases in plaque. Most studies have shown that the use of chewing gum or mints with xylitol three to five times a day, especially after eating, result in the greatest benefits. Other sugar-free sweeteners used in gum and mints offer some oral health benefits, but for maximal benefits use products with xylitol. For more information, read this health fact sheet xylitol and how it can protect your teeth. Although chewing gum or mints with xylitol helps reduce cavities, they do not replace the benefits of regular brushing and flossing.
One of the top personal sources of stress for Warfighters (according to a 2011 DoD survey) is money. Not enough money, not enough savings, or a bad credit history—all contribute to financial stress. For information and ideas on budgeting and saving money, check out this recent HPRC article. Another tool in your financial arsenal is the credit report. But first: What is a credit report?
A credit report is simply a record of your credit history. It includes your name, social security number, home address, credit cards, loans, collections, open amounts (how much you owe), and whether you have paid your bills on time (if late, it shows how late: 31-45 days past due, 46-60 days past due, etc.). In fact, you have more than one credit report; there are three major ones, so you need to pay attention to them all.
It’s important to have good credit reports—they have the information businesses look at to determine if they want to do business with you. This means if you apply for a credit card or loan, (1) are you worthy to get credit; (2) if you qualify, then what would the interest rate be; and (3) for an interest-free credit card or loan, what would the payback period be.
A number of businesses look at your credit reports: credit card companies, banks, mortgage lenders, cell phone companies, and even your insurance company. Employers can look at your credit history as well, but they must ask for your permission first.
It’s important to look at your credit reports for accuracy, especially with identity thefts, and to review the list of open credits that you may no longer use. Open credit is open credit—it can limit you in the long run because creditors know you have open lines of credit to use. The great news is that you can ask for a free credit report every 12 months from each of the three major companies, thanks to the Fair Credit Reporting Act (FCRA). Visit the Federal Trade Commission’s (FTC) website to see how to get your free credit reports.
