Physical fitness is important at any age, and it’s especially important that children begin leading healthy, active lifestyles early on. Regular exercise for kids can build strong muscles and bones and promote overall health. Exercise can also boost kids’ self-esteem, improve sleep, and stimulate learning in school. But do you know what kinds of exercise your children or teens should be doing? Check out HPRC’s Answer, “Put some fun in your children’s fitness,” to find out.
A 2011 study of musculoskeletal injuries in an Infantry Brigade Combat Team deployed to Afghanistan found that low back pain due to stress and strain on the back (not actual spinal cord injuries) was the most common complaint. Common causes of back injury include overuse, poor physical conditioning, and incorrect body movements when lifting and moving objects. Fortunately you can decrease your chances of injuring the muscles and ligaments of your back. The key is prevention: Stretching is one way to help prevent lower back pain, but it’s essential to use correct posture and body mechanics when you pick up and move objects such as heavy ammo cans! Daily back exercises (from the Mayo Clinic) and stretches can help strengthen your core and improve your posture, and the University of Maryland offers more valuable tips for prevention. If you’re experiencing back pain, however, you need to see a qualified healthcare professional for an accurate diagnosis and exercise program.
Staying in the physical condition you need for demanding duties and missions means that you are at risk for specific types of injuries, and rotator cuff injuries are common among service members. The rotator cuff is actually a group of muscles key to shoulder movement, including the ability to perform overhead activities. For those who are preparing for the CFT, this includes performing the Ammo Lift.
Warning signs of a shoulder injury can include not only pain and abnormal sounds during shoulder movement but also a decrease in strength and mobility/motion. What can you do about it? First, check with your healthcare provider to make sure that your injury does not require medical treatment. Then:
- Rest your injured shoulder! It is important to allow adequate time for healing.
- Use the RICE and ISE methods.
- Strengthen the muscles that control shoulder movement.
- Make sure that you have adequate flexibility of the rotator cuff muscles.
Of course, it’s always better to prevent injuries in the first place. To help reduce your risk of rotator cuff injury, it’s important to develop the strength and flexibility of the related muscles. For specific information on rotator-cuff exercises and self-care, check out these suggestions from MedLine Plus (a service of the National Institutes of Health) and this conditioning program from the American Academy of Orthopaedic Surgeons.
The Human Performance Resource Center is here to serve Warfighters and their families, commanders, and healthcare providers. If you’ve visited before, you probably know that we focus on “total force fitness.” But do you really know what that means—or how HPRC got started? If you’re curious, check out this PDF that describes HPRC, what we do, and the vast amount of information we cover. In addition, you may have noticed that we use the term “human performance optimization” throughout our site; this article also explains what that means.
The physical demands of military life are challenging, and if you’re not prepared, they can lead to injuries. The injury prevention series we’ll be running over the next several weeks will provide you with information and strategies for preventing some of the most common injuries: those to the knee, ankle, rotator cuff, back, iliotibial band and wrist/hand. Prevention is key: Taking time for the small stuff may have big payoff down the road. Much of what the exercises done for recovery after an injury can actually be done to prevent the injury in the first place. Stay injury-free for optimal performance! Check back soon for the first in this series.
Have you ever wondered why people who do the same resistance training workouts day after day aren’t getting the results they want? The goal of resistance training is to create an “adaptation response”—that is, to get your body to change in response to the demands. Once your body has adapted to a specific training program, you need to change the demands you place on it. If you don’t, you’ll find yourself eventually reaching a plateau where you don’t make any more gains—or sometimes even lose progress. One way to avoid this common training mistake is to implement “periodization”—the systematic shaking up of your routine (intensity and numbers of sets and reps). This method can optimize your training gains and minimize the risks of overtraining and injury. Implementing these training routines requires a strength training expert, so make sure you seek assistance. For example, the Army has implemented a new program for Master Fitness Trainers. And for more information on strength training, check out the HPRC’s Performance Strategies for Muscular Strength.
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.

For older men, it’s especially important to lead a healthy and physically active lifestyle since the risk for certain chronic diseases increases with age. Multiple studies have found that as little as 30 minutes a day of moderate- to vigorous-intensity exercise can significantly lower a man’s risk for heart disease and related risk factors such as diabetes, high cholesterol, and high blood pressure. Age is also a significant risk factor for developing prostate and colorectal cancers, which makes prevention and risk-factor management even more important for older men.
Exercise has been linked to lower risk and rates of death for prostate, lung, and colorectal cancers, the three most common cancers experienced by men. So get out there! Take a brisk walk, go for a jog, swim, bike, play tennis, even certain heavy outdoor yard work is acceptable for this purpose. If you need more structure, try a gym—many fitness centers offer military discounts on memberships and personal training sessions. Some military facilities also offer group and family recreational activities. The important thing is to find an exercise routine that you enjoy. If it’s not fun or motivating then it’s not likely to become part of your lifestyle.
The benefits of an active lifestyle are numerous, but prevention is one goal to keep your regular exercise program on the right track. Be sure to consult with your physician before starting an exercise routine, especially if exercise is new for you. Living a healthy lifestyle and getting screened for health complications are important ways to maintain readiness, resilience and optimal performance.
If you’re going TDY soon and your travel plans include an airport, read on. Don’t just step on to the people movers between concourses and then sit around while you wait. The American College of Sports Medicine (ACSM) wants you to turn your travel experience into an opportunity to get some exercise. ACSM’s “Exercise on the Fly” task force is promoting healthy air travel by getting people to think of airports as fitness centers: Every major airport is climate-controlled, with stairs and long stretches of walking areas. For layovers that last several hours, you might even have time to find a park or gym nearby outside the terminal. The task force is working with airport officials to post signs and other materials that promote walking while you wait. They also hope to publish a list of all physical activity opportunities at about 20 major hub airports in the United States. Remember that every little bit counts, even if it’s just a brisk 10-minute walk between terminals. So next time you head to the airport, be sure to throw a pair of sneakers in your carry-on for a workout on the go.
