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.
When training, an athlete should be specific about methods of training that meet the needs of the activity he or she is training for. To achieve an optimal performance level, a sprinter will train in a different way than, for example, an endurance athlete such as a marathon runner. Make sure that you “stress the physiological systems” right for your type of activity. In other words, if you are going to compete in a race, you need to run to become a better runner. Likewise, if you are going to compete in a cycling or swimming event, you must perform those exercises to become better. Wanna be a better tennis player? Play tennis! Although a well rounded program that includes strength training, aerobic conditioning, and flexibility exercises will improve your general fitness, to improve at a specific activity or sport you must perform that particular exercise.
Last week we started a series on survival tips for couples during the holiday season and discussed how many positive interactions couples need to do to make up for one negative interaction. This week, we're focusing on the “Four Horsemen of the Apocalypse”—a term coined by researchers for four features of communication that can destroy a relationship over time. Try to avoid these when communicating with your loved one:
- Criticism: Don’t made global negative statements about each other.
- Contempt: Don’t be sarcastic (in a mean way) or mocking towards your loved one.
- Defensiveness: Don’t respond to defend your behavior without first listening.
- Stonewalling: Don’t withdraw or ignore your loved one.
Too much of these characteristics has been linked to unhappy relationships over the long term. As stress and tensions rise throughout this holiday season, remember to be vigilant about avoiding these four kinds of behavior.

Eating disorders affect more women than men, and usually there is no single cause. Risks of developing an eating disorder can stem from genetics; biologic, emotional, and personality disorders, as well as family situations. Warfighters are not immune to these disorders and may even have a higher percentage than the general population. Having an eating disorder can significantly impact your performance. Not getting enough food or not eating healthy, consistent amounts of food means that your body is not being fueled optimally for performance. The University of Maryland Medical Center has put together a report on risk factors, causes, symptoms, diagnosis, and treatment for eating disorders as well as links to other helpful resources.
The Los Angeles Times is reporting on how the Marine Corps has hired 27 certified athletic trainers—most with experience tending professional and college athletes—to oversee training for enlisted recruits and officer candidates at sites throughout the United States. According to the article, this is a new direction for the Corps: Not that long ago, the drill instructors might have dismissed recruits who complained of being injured and ordered them back into action.

The holidays can sometimes be a difficult time for relationships. Through this holiday season, remember to compliment your loved ones and show them on a daily basis that you care for them. are thinking of them, and love them. Couples who do five positive actions for every negative one are more likely to have long, happy, successful marriages. Contrastingly, unhappy couples are more likely to have one positive interaction—or even less—for every negative interaction.

Do you really know what’s in that energy drink? There are different forms of stimulants in energy drinks, many of which are prohibited. The United States Anti-Doping Agency (USADA) has put together an information sheet on these “stimulant drinks,” including a helpful example of an ingredient label.
The Office of Dietary Supplements has released new fact sheets on multivitamin/mineral supplements. The QuickFacts version was designed for consumers; health professionals and those who want to know more can get additional detailed information from the Fact Sheet.
Overuse injuries are a common risk associated with the rigors of physical training. A healthy tip to implement into your training program is to gradually increase your training workload by just 10% each week. This will help—but not guarantee—to reduce the risk of muscle or joint injury such as tendonitis or stress fractures caused by repetitive trauma. In essence, keep the progressive changes in your activity levels gradual, listen to your body, and make incremental adjustments in time and intensity until you reach your new fitness goals.
