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. For more ideas on getting fit as a family check out Let’s Move, a comprehensive initiative by the First Lady. For military-specific resources, check out HPRC’s Family & Relationships domain.
Getting enough exercise is important to everyone’s mental and physical health in order to achieve optimal performance. Active-duty Warfighters usually get enough exercise in the course of their mission, but for the rest of us in the sphere of the military—family members, desk warriors, and the like—it can take more effort, so sometimes it’s helpful to review.
The Physical Activity Guidelines for Americans recommend that:
Aerobic exercise: For health benefits, adults should do at least 2.5 hours (or 150 minutes) a week of moderate-intensity exercise, or 75 minutes a week of vigorous-intensity aerobic physical activity, or an equivalent combination of moderate- and vigorous-intensity exercise.
- For the greatest health benefits, adults should do aerobic exercise of moderate intensity for five hours, or 300 minutes, weekly, or 2.5 hours or 150 minutes of vigorous-intensity aerobic exercise, or an equivalent combination of both.
- Do aerobic activity for at least 10 minutes at a time, preferably spread throughout the week.
- Don’t know how to gauge your exercise intensity? Check out ACSM’s video on aerobic intensity or the description from the Centers for Disease Control and Prevention (CDC). Examples of moderate-intensity activities include walking at three miles an hour, water aerobics, biking less than 10 mph, and gardening; vigorous-intensity activities include jogging or running, swimming laps, singles tennis, biking more than 10 mph, jumping rope, and hiking. Another method for determining exercise intensity is to keep track of your heart rate; use this explanation from CDC for how to determine your target heart rate for various activity levels.
- A general guideline for time spent exercising is that two minutes of moderate-intensity activity is equal to one minute of vigorous-intensity activity.
- For exercise ideas, check out ACSM’s video on types of aerobic exercise and/or HPRC’s Performance Strategies on Rebuilding Cardiovascular Fitness.
Strength training: Do muscle-strengthening exercises (resistance of moderate or high intensity) that involve all major muscle groups at least twice a week.
- For muscle strengthening, try doing 8–12 repetitions for each type of exercise. Do at least one set, but try for two or three sets for more benefits, at least twice a week!
- Be sure to work out your major muscle groups, including legs, hips, back, abdomen, chest, shoulders, and arms.
- For some muscle strengthening ideas, check out ACSM’s handout on basic strength-training exercises to do with just your bodyweight or their video of some basic moves you can do at home. Or try ACE’s step-by-step workouts for a total body workout, a30-minute lunch workout, total body conditioning for parents, and many more. Also, check out HPRC’s Performance Strategies on improving your Muscle Strength as well as your Core Strength!
Finally, remember to stretch after your workouts. For some basic ideas on stretching, check out ACSM’s pictorial sheet, their video on stretching basics, or HPRC’s Performance Strategies to “Improve your flexibility.”
Do you see physical education classes decreasing in your children’s schools compared to the PE you had when you were younger? Do you want to help your children be active and eat healthier, but you don’t know where to start? Tell your children’s school about the American Council on Exercise (ACE) program called Operation Fit Kids, which consists of two curricula for educators (free to download after completing a survey): one for 3rd to 5th graders and another for 6th to 8th graders. They provide seven lessons with lesson plans, worksheets, and activities a group can do to learn and practice being healthy. After all, practice makes perfect!

Water/pool workouts and swimming are great ways to give aching joints a break or recover from an injury and still get in a good workout. Exercising in the water provides the same aerobic fitness benefits as exercising on land. In fact, exercising in water may be less work for your heart; it pumps out more blood per beat, and heart rates are slightly slower. What’s more, pressure from the water speeds blood flow back to your heart, where your blood gets the oxygen that your muscles need during exercise.
Aquatic exercise is great for most people, including older and younger folks. Consider jumping in a pool to reduce stress and the risk for overuse injuries and as an alternative to your usual exercise routine.
Military servicewomen are exempt from physical fitness tests for a minimum of six months after giving birth. For many, though, this may not be enough time to get back to pre-pregnancy fitness levels. To date, studies have found that after pregnancy many active-duty women had slower run times, were not able to do as many push-ups, and had lower overall fitness scores compared to their pre-pregnancy fitness tests. One Air Force study found that sit-ups were the only component of the fitness test that didn’t change after pregnancy, despite increases in abdominal circumference. While exercise is generally recommended for women during pregnancy, there are many reasons why a lot of women stop, decrease, or are unable to do physical training during this time—having a baby is exhausting! Lack of sleep and sleep disturbances, quality and quantity of family support systems, breastfeeding needs, hormonal changes, and the physical stress of childbirth all impact recovery and performance. Getting back into an exercise routine takes time and patience. Discuss any possible restrictions with your doctor before starting. Begin slowly and at lower intensities until you feel stronger. Brisk walking, especially with your baby, is good exercise and good bonding time.
Attention, sailors! The first cycle of PFAs in 2013 is just around the corner. Don’t wait until the last minute to begin your training—postponing conditioning can lead to poor performance and even injury. Spring PFAs are typically conducted in May, so there’s still time to prepare for peak physical fitness. There are several resources you can refer to in case you’re not sure where to start. For more information on the Navy’s Physical Readiness Program—including guidelines, failure process, and assessment tables—refer to OPNAVINST 6110.1J. The Navy also provides sample workouts and the NOFFS app to help you with your training plan.
Approximately 300 million people around the world have sickle cell trait (SCT), including approximately 9% of African Americans. It is a hereditary condition in which red blood cells are affected, but most people who have it never experience symptoms. (It is important to note that SCT is not the same as sickle cell disease [SCD]. Sickle cell disease [or sickle cell anemia] can lead to other serious clinical risks and can cause severe symptoms. Those with the SCD usually have a shorter lifespan.)
Individuals with SCT usually can participate in normal physical activity and sports, as SCT doesn’t seem to adversely affect performance. In fact, some studies have found that those with SCT excel in short-distance power activities such as sprinting and jumping.
While SCT is largely a benign condition, there have been related complications such as exertional rhabdomyolysis and exercise-related sudden death. They have been found in non-SCT individuals as well, but they occur at higher rates in those with SCT and are a “hot topic” in military, and civilian communities; the National Collegiate Athletic Association even requires screening for all its Division I and II athletes.
It has been suggested that those with SCT may be more prone to sudden death from dehydration, heat illness, and high-intensity exercise; however, these factors and the role of prevention standards, medications, and the use of dietary supplements are still being studied. In both military and civilian SCT populations, collapsing during exercise is most commonly observed during times runs and sprints within the first few weeks of conditioning. SCT Recruits who have difficulty passing the Physical Readiness Test are also at higher risk for collapse. Military leaders should be aware of safe training guidelines and take universal precautions. Effective prevention tactics include heat acclimatization, hydration, gradual physical conditioning, and addressing progressively worse symptoms early on.
All newborns in the United States are screened for both SCT and SCD as part of a public health imperative. Each military branch has its own policies regarding SCT. The Army does not screen for SCT but promotes universal precautions for all soldiers, whereas the Air Force, Navy, and Marines all screen for SCT after accession. Further testing and counseling may be done for those who are positive for SCT. If you are unsure about SCT and exercise, consult with your physician, especially if you are starting a new exercise routine.
