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.

Attention, all disabled service members and veterans! Staying active helps with recovery by rebuilding strength and endurance—and in so many other ways, as well. A positive mindset and a supportive community are as important as fitness, and getting involved sports such as snowboarding, cycling, wheelchair basketball, and others can build both physical fitness and mental resilience. Consider checking out the Warfighter Sports Program developed by Disabled Sports USA. It offers more than 30 winter and summer adaptive sports in more than 150 events nationwide. Instruction, equipment, and transportation are provided to Warfighters and their guests. Become a part of the team and find the events happening in your area today!
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.
If you want improve your PFT and/or CFT score then try performing a dynamic warm up before the test. While there is still much debate around a pre-exercise warm-up, a recent review of the literature specific to military testing found that dynamic warm-up and dynamic stretching might improve your fitness test performance. Overall, dynamic warm-ups appear to improve pull-ups, push-ups, power, flexibility, and aerobic performance. In addition, prior to the dynamic warm-up, an aerobic warm-up such as about five to 10 minutes of light jogging, swimming, or cycling sees to have an overall beneficial effect on cardiovascular assessments such as sprinting and running. On the other hand, static stretching (the kind you stretch and hold) appears to have a negative effect on exercise performance in trained populations. If range of motion is needed, then static stretching might be the most beneficial type of warm-up. Most services no longer test for the sit-and-reach, but there are some commands that continue with this testing modality. While nothing will help you more than properly training for your fitness assessments, doing the little things on testing day may help you achieve peak performance.
Deployments, injuries, transitions—just a few of the many things that can interfere with your normal exercise routine. Too long a break and your cardiovascular—or aerobic—fitness may suffer. For optimal performance, however, getting your heart and lungs back in action is critical. If you’ve been away from your routine for a while, start slowly and gradually increase intensity and duration. Be patient and stick with a routine, even on days you don’t feel like it. Mix up your routine when you’re able with different types of aerobic exercise such as biking, running, swimming, and rowing. For help planning your comeback, check out HPRC’s Performance Strategies for Rebuilding Cardiovascular Fitness. If you’d like to learn more about aerobic conditioning specifically for the PRT/PFT, read part 1of our training series.
Looking to define your glutes, hips, and thighs? Want a total body workout to help you improve your score on the next PFT? Not close to your unit? You can access workouts complete with warm-up, cool-down, and videos of each exercise all online. There is a variety of routines, so depending on what you are looking to get out of a workout, there may be one for you. This is a handy resource for all Warfighters, but reservists and National Guardsmen often can’t work out with their unit, so these videos could provide a new twist to an individual workout. If you are far from your unit and are not able to participate in unit physical training, try these workouts! Sport-specific workouts are also available for the cyclists or swimmers in the service.
May is National Physical Fitness and Sports month so get out and get moving—and include your family! There are lots of great reasons to add exercise to your daily routine: It decreases your risk for chronic health problems such as diabetes and cardiovascular disease and improves your mental health. Getting outside for a walk with your children can be great bonding time and may even help them (and you) sleep better at night! You can find ideas to incorporate physical activity into your life, including interactive tool kits and planners, at the Federal Occupational Health website. HPRC also provides resources (family friendly ones, too) to help you get started and stay on track!
The annual Army “Strong B.A.N.D.S.” campaign is set to launch for another year beginning in May. Strong B.A.N.D.S. promotes physical fitness, nutrition, optimal health, and resilience by focusing on Balance, Activity, Nutrition, Determination, and Strength—forming the acronym B.A.N.D.S. The campaign has activities at numerous garrisons to help educate soldiers, their families, and civilians. Strong B.A.N.D.S. is a campaign of the U.S. Army Installation Management Command Family and Morale, Welfare and Recreation directorate and is “designed to energize and inspire community members to live a healthy lifestyle.”
Check out the website for detailed information and to see if there is a Strong B.A.N.D.S. activity near you.
Previously HPRC reported on how much physical activity healthy adults need. This week, the spotlight’s on children and teenagers—and whether they’re getting the exercise they need.
According to the Physical Activity Guidelines for Americans, children and adolescents need at least 60 minutes of physical activity every day, including:
- Aerobic exercise for most of the 60 minutes. Most days can include either vigorous-intensity activities (such as running, swimming, and jumping rope) or moderate-intensity activities (such as walking or skateboarding), but at least three days a week it should include at least some vigorous-intensity exercise. Check out Let’s Move! for ideas on how to get active as a family.
- Muscle-strengthening activities such as playing tug of war, exercising with resistance bands, or climbing on playground equipment. Strengthening exercises should be done at least three times a week. For safety guidelines on strength training for children and teens, check out this article from HPRC.
- Bone-strengthening (impact) activities such running, jumping rope, basketball, tennis, and hopscotch. Impact activities strengthen bones and promote healthy growth and also should be done at least three times a week.
For more ideas on moderate- and vigorous-intensity aerobic activities, as well as muscle-strengthening and bone-strengthening physical activities, check out the table in Chapter 3: Active Children and Adolescents of the Physical Activity Guidelines.
