HPRC Fitness Arena: Total Force Fitness
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.
Both deer velvet and IGF-1 have been in the news lately, and HPRC has received many questions about what these are and whether they improve athletic performance. Does deer velvet contain IGF-1? Read this OPSS FAQ about deer velvet to find out. To learn what IGF-1 is and whether it is banned in the military, read more in the OPSS FAQ about IGF-1. Be sure to check back often, as we add answers to other questions about ingredients in performance and weight-loss supplements and how to choose supplements safely.
We all know that falling in love with your significant other is a key feature of a romantic relationship—but did you know liking goes hand in hand with loving? The results of numerous studies found that those who both love and like their significant other are more likely to be happier and have more stable long-term relationships. Without both, couples are more likely to be dissatisfied or dissolve the relationship. Couples who both like and love each other are also more likely to assure each other of their feelings, be open with each other, and share tasks together—all behaviors that maintain happy relationships. Liking as well as loving your partner is the most fundamental characteristic of a good relationship.

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.
Everyone experiences anger—it’s normal. It’s also normal that the people you love will make you angry at some point. The trick is figuring out how to manage your anger—an essential skill for yourself and your relationships. Not dealing with anger just makes the situation worse. Afterdeployment.org has handouts on different aspects of Anger and Anger Management to get you started, including Anger Cues and Measuring Anger, Myths About Anger, how to manage anger with Time-Outs, and how to create an Anger Control Plan.
Hiking is a great form of exercise and a great way to get outdoors and enjoy some scenery—especially when getting ready for deployment to challenging terrain. If the weather outside is less than ideal, however, or the winter temperatures become too frigid, you may need to move your hiking indoors to a treadmill. Keep in mind that you might not be working as hard on a treadmill as you would be hiking outside at your regular pace. Hiking requires different, often heavier footwear and involves a more diverse, varied terrain, both of which require more energy than walking in sneakers on a treadmill. If you want the same benefits, your treadmill needs to be set to at least a 3% incline for any speed up to 3.1 miles per hour to be comparable to what you expend hiking outside. You can still train for that mountain trek in bad weather—you’ll just need to make some slight adjustments. Happy trails…or treadmilling!
Motion sickness can affect even the strongest Warfighters. Nausea, vomiting, dizziness, and sweating are some of the telltale signs of kinetosis, or motion sickness. The potential impact on individual and force readiness make it a concern in military medicine.
Motion sickness may affect individuals differently, but generally it follows a pattern. The earliest symptom typically is abdominal discomfort. If the motion continues, discomfort is usually followed by overly warm sensations, nausea, and wanting cool air.
Motion sickness can be alleviated to a degree by following these simple tips:
- Pick a seat where motion is less likely to be felt, such as an aisle seat on a plane, a central cabin on a ship, or a car toward the front of a train.
- Avoid sudden movements of the head, which can aggravate motion sickness.
- Avoid tasks that involve prolonged close-up eye movement or focus (such as reading a book). Focus instead on the road in front of you or on a distant object so that your senses can confirm that you’re on the move.
- Avoid alcoholic beverages before and during a trip, as alcohol can worsen motion sickness.
- If possible, expose yourself to the motion in gradually and in stages until you adapt to the movement.
Jerome Greer Chandler, a former combat medic, describes the severity of motion sickness among U.S. service members in an article to The American Legion Magazine [PDF]. For a detailed reading on motion sickness and its effect among military personnel, see the Textbooks of Military Medicine (volume 2).
Caring enough to really listen when someone needs it—also known as being someone’s “wingman”—can make a big difference in a Warfighter’s life. Being a wingman means showing care and concern for a buddy consistently—if you’re separated, for example, it means staying in touch and checking in regularly to make sure you’re both okay. When a buddy is thinking of hurting himself or herself, a great wingman skill to use is ACE—the acronym for “Ask, Care, Escort.”
Ask. If you are concerned, ask directly, “Are you thinking of killing yourself?”
Care. Next, as wingman, care for your buddy by staying with him or her, actively listening, staying calm, and removing anything he or she could use to hurt him/herself.
Escort. Finally, take your buddy to someone who is trained to help, such as a primary care provider, chaplain, or health professional, and call the National Suicide Prevention Lifeline or 911 for additional support.
Coconut oil has a sweet taste that lends distinct flavor to foods, and it contains several saturated fats—something the 2010 Dietary Guidelines for Americans suggest we eat less of. That is because eating saturated fats has been linked to atherosclerosis (“hardening of the arteries”) and increased risk of heart disease.
Although coconut oil is highly saturated, it has different types of saturated fats. One of these—lauric acid—is regularly touted as having performance benefits. Lauric acid is referred to as a “medium chain fatty acid” (MCFA), and the body processes MCFAs differently than it does “long chain” fatty acids (LCFAs). Importantly, MCFAs are digested more rapidly than long chain fatty acids, so they are quickly absorbed and available as an energy source. Some research suggests MCFAs might help to optimize and maintain glycogen stores, thus extending endurance performance. Not only that, MCFAs are less likely than other fats to be stored as fat—a plus if you’re concerned about weight control. The performance claims surrounding MCFAs and coconut oil have not held up, and claims about their weight loss benefits need more research.
The American College of Sports Medicine and the Academy of Nutrition and Dietetics joint guidelines for Nutrition and Athletic Performance indicate that MCFAs do not provide any performance benefit. To date, only two studies have shown improvements in performance. On the other hand, MCFAs have been shown to increase the body’s use of “fats” as fuels, reducing food intake, so such products may promote weight loss. There just isn’t enough information available to make any scientific conclusions.
If you choose to eat coconut oil, do so in moderation for its unique flavor and texture, because its health and performance benefits are still open for consideration.
