If you’ve ever had a back injury, you know that the recovery process can take weeks, months, or even years—this is referred to as a chronic condition. Preventing injuries to the back can save you from going down this long road to recovery. Check out our new article on back injuries that includes tips on lifting heavy objects, strengthening the muscles of the back, and maintaining adequate flexibility in the muscles, tendons, and ligaments.
Your knees are major weight-bearing joints and require some ongoing care to keep them functioning well, regardless of your MOS or sport activities. A new HPRC article on knee injuries provides information on knee-injury prevention. We focused on the anterior cruciate ligament (ACL) because this injury is quite common in the military and can put a soldier on profile for six months or even more. ACL injuries typically require surgery, so it’s an injury you want to avoid, if possible. Scientists and researchers have discovered some specific information that can be useful to decrease your risk of ACL injuries.
Ankle injuries are quite common in the military, and you put yourself at a greater risk for sprains and strains if your ankles are weak. There are some simple tips you can use to keep your ankles healthy, including choosing the proper footwear and maintaining adequate strength in the muscles that control movement of your ankles. Check our new information on ankle injuries.
HPRC continues its series on Pain Management with an article on epidural steroid injections (ESIs), which involve injections of pain medication around the spinal nerve roots. They are done by qualified healthcare providers for short-term relief of back and neck pain. They also can help doctors diagnose some types of pain. Learn more in HPRC’s “Epidural Steroid Injections for Pain."
Many military jobs require that you have strong and healthy shoulders. So whether it’s performing well on your push-up test during the PRT or moving the ammunition can during the CFT, you need your shoulders to function well. HPRC has rolled out a new Injury Prevention Strategies series, which includes tips on preventing shoulder injuries. Check out the information on strengthening and flexibility exercises and get started today!
A staggering number of Americans (approximately 36 million) have hearing loss, and one-third of those probably could have been prevented. Hearing loss continues to be a safety hazard for Warfighters at home and in the field. So how do we combat this not-so-silent epidemic? Here are a few tips to help you protect your hearing.
- Wear a hearing protective device (HPD). HPDs should be worn for noise levels at or above 85dB. Not sure what 85dB really means? Check out this guide to occupational noise levels. Also check out “How Loud is Too Loud?,” a graphic designed to inform Warfighters about how and when to choose the proper HPD for their jobs.
- Learn how to wear your HPD correctly. Even if you have the correct protection, it may not be effective if you’re not wearing it correctly.
- Always have disposable HPDs handy. Disposable HPDs are lightweight and easily portable. Make them a part of your everyday gear.
For more information about how to protect yourself against or to seek help for hearing loss check out the DoD Hearing Center of Excellence website or make an appointment with your local hearing loss treatment center.
HPRC previously ran an Injury Prevention series with some general information to help keep you off profile. A new addition to the series is Injury Prevention Strategies, which will include information for the knees (specifically the anterior cruciate ligament or ACL), ankles, shoulders, and back. Check back often for the next in the series, and keep your body functioning at the top of its game!
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.
Not only is exercise good for the body, it’s good for the mind. The expert consensus from the International Society of Sport Psychology is that exercise can increase your sense of well-being and help reduce anxiety, tension, and depression.
For veterans coping with depression, PTSD, or other mental-health issues, sports and exercise may be a great way to relieve stress. Scientists have shown the positive benefits of physical activity on symptoms of depression in veterans. What’s more, Veterans’ Administration studies have found that physical activity—especially vigorous activity—can decrease the risk of PTSD among Warfighters. The opposite is also true: Veterans who do not engage in physical activity are more likely to experience PTSD. Several organizations specialize in physical activity and exercise for warriors and their families, but you can always try a yoga class, a family bike ride, or other fitness opportunities in your community.
Getting motivated to exercise and stay active can be especially difficult for those suffering from PTSD and depression. Here are some tips to help you get up and get out the door.
- Make a date with yourself. Put it on your calendar or set a daily alarm—whatever you need to do to remind yourself that you’ve set aside some time for you to exercise. And don’t stand yourself up!
- Set a SMART goal and write it down. Post it on your bathroom mirror, your fridge, your car dashboard—wherever you’ll see it daily to remind yourself of what you want to accomplish.
- Recruit friends or family members to help. Telling people what your goals are is a great way to stay accountable. An exercise partner is especially helpful when you need that extra nudge to get off the couch and start moving.
- Keep a journal. Record your exercise activities and how you felt afterwards. While you may not feel better after every workout, you probably will most of the time. Being able to go back and read/remember how good exercise made you feel may motivate you for the next workout.
