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.
One review of studies on the effects of plyometric (explosive jump) training, or PT, suggested that plyometric training can enhance vertical jump ability and leg power for healthy individuals. This training can be as simple as drop jumps, counter-movement jumps, alternate leg bounding, and hopping. And there are PT exercises for the upper body, too! The purpose of PT is to improve your athletic performance by increasing the speed or force of muscle contraction that enables you to jump higher, run faster, throw farther, or hit harder during a game. The full article is available online from the British Journal of Sports Medicine.
As a non-deployed parent, taking care of yourself is important. Taking time just for you has been linked to better parenting, healthier lifestyles, and greater satisfaction with life overall. Also, parental can model healthy ways to manage and cope with stress that effectively decrease children's worry, as they sometimes express concern over their parents’ health and support. Real Warriors suggests scheduling time to relax with a book, do gardening, or practice yoga. Volunteering at a local charity is also a great way to provide both personal satisfaction and connection to community.
Although regular exercise can improve sleep (see this HPRC article), your workout time may be putting you in a less-than-ideal state for a good night’s rest. Exercise not only makes you more alert but also raises your body temperature, both of which can make falling and staying asleep more difficult. To create healthy sleep habits, the National Sleep Foundation (NSF) recommends that you finish your workout at least three hours before you go to bed. View more healthy sleep tips on the NSF website.
Everyone remembers where they were on September 11 ten years ago when the terrorist attacks on the World Trade Center and Pentagon occurred. Retired Navy Capt. Stephen Frost—now Director of the Human Performance Resource Center—was at the Pentagon when the building was hit, and he was one of the first medical personnel to arrive at the disaster. Read this DoD article to learn more about his life-changing experience.
In order to improve your athletic performance, you need to include strength training in your workout routine. Having a solid strength-training program can help you meet your sports and performance goals more easily by improving overall strength and delaying fatigue. Including this type of training will help you get bigger, faster, and stronger to stay a step ahead of your competitors. Your program should focus on the major muscle groups: chest, back, thighs, calves, biceps, triceps, and shoulders. Training these areas will help you become a better athlete while also improving your physique. For more about how to incorporate strength training into your routine, read the Strength Training Section of the Sports Fitness Advisor website.
“Capitalization” refers to the process by which people share good news with one another. Studies have shown that responding to good news with support and enthusiasm helps build a stronger relationship between two individuals. Using capitalization with your loved ones can not only strengthen your relationship, but also can ease the transition for returning Warfighters and their loved ones.
The last excuse a trainer wants to hear from a client is that they don’t have enough space—or the right space—to exercise. The truth is that with a little effort and imagination, you can find a whole world of places and practices to improve your strength and endurance. Just think about all the free equipment outside at the park, on your way to work, or at your child’s school playground. You can make use of just about anything. Want to gain upper body strength? Start climbing the monkey bars and don’t stop ‘til you drop. Or try push-ups—a great way to get moving without standing in line at the gym. All you need for walking or running is a good pair of shoes and any path, road, or bike trail—the same places work for a bicycle, too, and they don’t cost a dime. By now you should be getting the picture. Just get rid of that mental block about needing a special place or equipment that is keeping you from getting a healthy, fit body. Just think of all the new forms of exercise waiting for you the minute you walk out the door! Here are five simple exercises to get you started.
Young children need consistency and predictability in the environment in which they grow up. Maintaining consistent expectations with regards to education, work, and family responsibilities is crucial in a child’s healthy development, as well as for family relations. A great way to achieve a sense of consistency is to create family rituals. MilitaryOneSource suggests rituals such as reading letters aloud during dinner and eating together as a family.

HPRC recently wrote about “The Lure of Jack3d” and answered a “Question from the Field” about . Jack3d is marketed as a pre-workout supplement and OxyElite Pro is marketed as a fat-burner product. Both contain the ingredient 1,3-dimethylamylamine (DMAA). Since we last wrote about both products, there have been new reports about DMAA.
Makers of Jack3d and OxyElite Pro claim that DMAA is a “natural constituent” of the geranium plant. DMAA was originally patented as a drug in the U.S. by Lilly in the 1940s. Since then, it has been identified on many product labels (especially on sport, energy, and weight-loss products) as being derived from geranium oil, stem, or extract, but review of the scientific literature has not substantiated this claim. To date, there is no credible scientific data that establishes the presence of methylhexanamine in geranium. Recently, the American Herbal Products Association announced that products containing DMAA (which can also be seen on labels as 1,3-dimethlypentlyamine, methylhexaneamine, or MHA, in addition to 1,3-dimethylamylamine) should be labeled as such and not as geranium oil or any part of the geranium plant. Health Canada has clarified that DMAA is a drug and must go through appropriate drug approval processes before it is used in any product. The United States Anti-Doping Agency (USADA) has long warned athletes about dietary supplements and more recently about the inclusion of methylhexaneamine in products under the guise of “geranium”; USADA has recently issued an advisory to athletes. There are questions about whether DMAA may be legally included in dietary supplements, since there is no credible evidence that it is present in geranium and it has not gone through the New Dietary Ingredient notification process with the Food and Drug Administration. Therefore, caution is advised when considering whether to use a product that contains this ingredient. Please be aware that such products may be sold in large retail nutrition outlets and on the Internet.
