Have you ever felt great after a hard workout, only to find yourself incredibly sore a day or two later? Muscle pain a day or so after exercise is common among recreational athletes. Known as delayed onset muscle soreness (DOMS), this condition can be treated at home—and possibly even prevented—with simple techniques. Strategies to prevent or reduce DOMS include stretching, protein/carbohydrate recovery drinks, and cold-water immersion. Over-the-counter medications can also help with pain but should be used infrequently and at the lowest effective dose. For more detailed information about DOMS and how to prevent and recover from it, read HPRC’s Answer, “Delayed Onset Muscle Soreness.”
The saying goes that “less is more,” but when it comes to exercise intensity, that might not be the case. We know that some exercise is better than no exercise, but is more-intense exercise better than moderate exercise? How hard should you push? And what are the benefits? With the growing popularity of high-intensity workouts, it’s important to consider both the risks and the benefits.
The role of intensity during exercise has been studied before. For example, the risk of death in older adults is lower for those who walk at a faster pace than for those who walk at a more leisurely pace. However, new research demonstrates that pushing yourself during a workout not only helps make you mentally tough but may also release chemicals into your body that help you develop bigger, stronger muscles.
During “stressful” or high-intensity exercise, your body kicks into “fight or flight” mode and releases hormones such as adrenaline and dopamine to push your system into high gear: increased heart rate, increased breathing rate, and increased oxygen to muscles. A recent study found that these hormones, when released during stressful exercise, sent messages to muscle cells to develop larger and more efficient muscles—at least in mice. The body only releases these chemicals when it feels stressed (for example, during intense exercise). If the body doesn’t feel stressed (as during light exercise), it doesn’t release these chemicals, so it can’t send signals to the muscles.
The good news is that exercise intensity is relative, so anyone should be able to exercise at a level that releases these hormones. Whether you’re just starting out or you’re a seasoned athlete, you can exercise to a level that is intense for you. Shooting for your target heart rate is a good start to gauging intensity. Not every workout needs to top out the intensity scale. In fact, doing too much too often can lead to overtraining and potential injury. Remember to listen to your body and incorporate rest or light days into your workout regimen.
Activity monitors have become increasingly popular tools to help people get and stay on track with their fitness (and dietary) goals. But, researchers from Iowa State University wanted to see just how accurate some of the popular monitors really are when it comes to reporting how many calories you burn during exercise. It turns out that the majority of the devices they tested gave pretty accurate estimates (within 10-15% error). The BodyMedia FIT was the most accurate one tested, with only a 9.3% error rating, which is close to some more expensive devices used for research purposes. Other monitors such as the FitBit Zip, FitBit One, Jawbone Up, and Nike Fuel Band all fell below 15%. Since many people tend to overestimate their activity levels on their own, an accurate activity monitor is an important tool to help people keep better track of their exercise habits. Check out our comparison chart to find out more about these monitors.
Have you heard of Total Force Fitness, but you aren’t sure what it is? It’s a framework for building and maintaining health, readiness, and performance in the Department of Defense. It views health, wellness, and resilience as a holistic concept that recognizes “total fitness” as a “state in which the individual, family and organization can sustain optimal well-being and performance under all conditions”—a connection between mind, body, spirit, and family/social relationships. Total fitness shifts the perspective from treatment to wellness and focuses on prevention and strengths.
The Defense Centers of Excellence for Psychological Health and Traumatic Brain Injury created a slide presentation for units and groups on Total Force Fitness: A Brief Overview that describes what TFF is, its core components, and each of its eight “domains” (behavioral, social, physical, environmental, medical and dental, spiritual, nutritional, and psychological). For more in-depth reading, check out the original Military Medicine Supplement that started it all, including a scholarly chapter for each domain.
In recognition of National Physical Fitness and Sports month, Army garrisons across the globe are teaming up for the 4th Annual Strong B.A.N.D.S (Balance, Activity, Nutrition, Determination, and Strength) campaign under the Army MWR program. The campaign hopes to enhance community resilience through awareness of the health and fitness opportunities available to Warfighters and their families. Participating garrisons will host events such as volleyball games, swimming events, and golf tournaments. The Human Performance Resource Center has teamed up with Strong B.A.N.D.S to provide information cards on topics such as diet, injury prevention, and supplement safety to help you stay strong, ready, and resilient!
Check out the Strong B.A.N.D.S video montage from past years to get an idea what to expect!
Do you exercise to music? If you do, you might have noticed that you run faster when a fast-paced, upbeat tune comes on.
Exercise scientists noticed the relationship between exercise and music some time ago. For those of us who aren’t trained athletes, music can have a huge effect on our performance and mood during exercise. Without realizing it, people push themselves harder during exercise when listening to fast-tempo music, which increases heart rate as well as speed, endurance, and in some cases the rate of perceived exertion. Exercisers also feel an improved sense of well-being when working out to music.
So why is it you prefer certain songs when you’re exercising? One explanation suggests that a part of your brain tries to match the movement of your body to the beat of the music. In fact, scientists have found that when you listen to music with about 125–140 beats per minute, both your heartbeat and your movements synchronize to work at the most energy-efficient, optimal level for exercise. In essence, music works with your brain to coordinate your bodily functions and optimize your workout.
The best workout songs seem to share certain characteristics:
- 125-140 beats per minute during exercise; slower for warm-ups, cool-downs, and for some endurance-type exercises
- A motivational or upbeat message
- Familiar tunes or a preferred style of music
- A tempo that matches the rhythm of your exercise
Ask your buddies about their workout playlists too. They might have something totally different to offer—a new beat to stay fit with.

The Performance Triad is well underway, and the Army has been closely monitoring the progress of soldiers at the three test sites (Joint Base Lewis-McChord, Fort Bliss, and Fort Bragg). Soldiers will be assessed on their knowledge, beliefs, and attitudes about the parts of the triad—sleep, activity, and nutrition. Triad staff is currently performing injury-risk assessments for the Military Power, Performance, and Prevention (or “MP3”) program as part of an ongoing process that helps get soldiers into physical therapy and strength-training programs to help reduce the number of “medically not ready soldiers.” You can read more about the Performance Triad in HPRC’s Total Force Fitness domain.
Wanting some holistic strategies to enhance your performance? Check out the “One Shot One Kill (OSOK) Performance Enhancement Program” that shows Warfighters how to set up and manage their own performance-enhancement system. OSOK is designed not only to enhance performance but also to jumpstart Warfighter resilience. It builds on the skills that Warfighters already possess and then teaches new ones as needed.
There are two ways you can use OSOK: as an individual through “OSOK Solo” and as a unit/group through “OSOK-IP Unit.” Both highlight “10 Rules of Engagement” and provide seven core modules: Controlled Response, Mind Tactics, Performance-Based Nutrition, Primal Fitness, Purpose, Code, and Recharge. OSOK also provides self-assessment forms so you can track your progress over time.

You can also find these videos and other training resources online in HPRC’s Physical Fitness domain.
You’ve been training, and now you’re in pain. It could be you’re having a painful introduction to one of your tendons. Strong tendons connect your muscles to the bones in your body and help you move by pulling on the bones when your muscles contract. Damage to tendons can occur from repetitive activities (including running and firing your weapon repeatedly over an extended period of time) or from sudden movements that put too much stress on a tendon. If you can’t avoid these activities, then pay attention to the warning signs that a tendon could be reaching its breaking point: pain, especially when moving the affected area; swelling over the area of pain; and, possibly, loss of motion in the joint.
The best way to avoid having to get treatment for tendonitis is to prevent it from happening in the first place! Follow these tips:
- Overall health: Maintain a healthy diet and weight, and check out HPRC’s Nutrition domain.
- Posture and body mechanics: Pay attention to your posture and make sure that you use correct body mechanics, especially when lifting and moving heavy objects.
- Maintain adequate muscle strength so your body can react to stresses you place on it.
- Maintain adequate flexibility.
- Consider proper workout gear, especially footwear; check out this HPRC article for more information.
- Activity modification: Rest the affected area. This could mean taking some time off from activities that cause pain and further damage. For example, if you’re a runner with Achilles tendonitis, try biking instead until the tendon has healed enough.
- Ice: Cold can help to decrease pain and swelling.
- Physical therapy: Gentle stretching and strengthening exercises, as well as massage, might help but should be done under the supervision of a healthcare provider.
- Anti-inflammatory medications: Ask your physician about medications that can help your condition.
- Bracing or casting might be needed in severe cases.
You should see your doctor right away if you experience fever, redness, and warmth in the affected area, or multiple sites of pain. For more information on injury prevention, check out HPRC’s “Preventing common injuries,” which covers six specific areas of injury: wrist and hand, knee, ankle, rotator cuff, back, and IT band.
