There’s an unpleasant situation that runners sometimes experience called “runners’ trots” or diarrhea. While short lasting and generally harmless, they can be annoying and cost you time during training or a race.
Certain activities such as high-intensity or long-duration exercise and vertical-impact sports (e.g., running vs. biking) increase your risk of gastrointestinal (GI) discomfort. Dehydration, poor conditioning, medication, and eating habits can cause GI irritation too. Despite the lack of hard evidence as to what causes these GI issues, there are things you can do to help settle your stomach:
- Avoid trying new foods or sports drinks during a race.
- Increase the time between eating and activity. Wait at least 3 hours after eating a large meal, or eat a smaller meal or snack closer to training time.
- Plan out your meals, especially for endurance events.
- Pay attention to what you eat to help identify foods that increase your discomfort during running. It’s best to avoid these until after you finish your race.
- Limit your intake of gas-forming or fiber-rich foods (e.g., broccoli, onions, and beans).
- If you’re sensitive, avoid coffee and other forms of caffeine before a run.
- Hydrate before and during endurance activities; it will help blood flow to the GI area.
- If you use sports gels or chews for endurance events, drink enough water (three to eight ounces every 15–20 minutes) to stay hydrated.
- Give yourself time to use the bathroom before an endurance exercise.
- Increase distance and intensity gradually.
If symptoms persist for more than a few days, even at rest, seek medical attention. Enjoy your run!
Whatever your goals are, keep in mind that they’re easier to accomplish when they’re SMART goals:
It’s a well-established method for fitness-oriented goals—to lift a certain weight, cycle a century, or run a marathon in a certain amount of time—and it works equally well in other areas of life. Maybe you want to reach a specific rank at your job or finish college by a certain date. Goals aren’t just for dreaming big; they’re for achieving.
- think through exactly what you’re aiming for;
- determine if this goal is a good fit for you;
- measure and track your progress;
- use success-oriented language to think and talk about your goal; and
- break down the end goal into manageable steps.
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.
Being overweight puts you at risk for a whole host of health issues, but most people don’t think about the risk posed to their knees. The anterior cruciate ligament, or ACL, is one of the major ligaments of the knee and one of the most susceptible to injury. Injury information on more than 1,600 men and women at the U.S. Naval Academy showed that those with a higher body mass index (BMI) had a greater incidence of ACL tears. A difference in BMI of only 1.2 (25.6 versus 24.4) made the difference between having and not having this kind of injury. (To learn more about BMI, read HPRC's explanation.)
Like the adage “You don’t know what you’ve got until it’s gone,” knees are something we generally take for granted. To stay on top of your game, you need your knees. An easy way to protect them is to drop the extra weight you’re asking them to carry around.
Warfighters and family members looking to track their food choices now can use the United States Department of Agriculture’s Agricultural Research Service (USDA-ARS) National Nutrient Database for Standard Reference (called The Standard Reference or SR). This nutrient data is widely used and has been incorporated into many smart phone “apps” and interactive websites. Of particular interest is the USDA’s SuperTracker, where users can customize their dietary plan and physical activity. For more information, read how to access this nutritional data.
In October 2012, students at the Uniformed Services University of the Health Sciences participated in Operation Bushmaster at Fort Indiantown Gap, PA. The exercise involved a simulated combat environment to test the limits of their physical fitness as well as mental resilience. Military medical students were tasked with managing patient flow in an operational environment, such as tactical relocation over uneven terrain and dealing with changes in environmental conditions.
From a human performance optimization (HPO) standpoint, take-home points for the practical exercise included the importance of being physically fit, especially following guidelines for the prevention of back injuries, and implementing mental strategies for coping in high stress situations.
Part of a comprehensive fitness program involves improving your muscular strength and endurance. One way to figure out how much weight you should be lifting is to determine your one-repetition maximum (1RM). The American College of Sports Medicine recommends lifting 8–12 repetitions of 60-80% of a person’s 1RM to improve muscular strength and endurance. However, doing a 1RM test isn’t always feasible or safe if you don’t have someone to spot you. Instead, try using this this quick-and-easy calculator to estimate what your 1RM should be for a given exercise.
Lugging around heavy weights and other exercise equipment while traveling or on deployment isn’t the most practical idea. Pack a couple of suspension-training straps, however, and you’ve got part of a well-rounded training routine covered. Suspension training has gained a lot of popularity among both civilians and service members alike, and more and more gyms are now offering suspension-training classes. Once the straps are securely anchored to something that won’t move and is sturdy enough to hold your weight, place your hands or feet into the loops, and your body weight enhances the effectiveness of exercises such as push-ups, lunges, core strengthening, and more. While there are various ways to adjust and adapt the exercises for less experienced exercisers, this type of workout requires some initial joint and core stability. There is also potential risk of injury, especially for beginners. Before you try this for the first time, it’s a good idea to get some advice and guidance from a suspension-training professional.
The Army has several resources to help you train for the Physical Fitness Test (APFT) and to build and maintain your fitness levels throughout the year. HPRC has issued a series of documents to help you increase aerobic fitness as well as muscular strength and endurance. Under the Army PRT tab in our Physical Fitness Program Guides section you will find links to videos that demonstrate specific preparation, conditioning, and recovery drills found in TC 3-22.20, Army Physical Readiness Training, as well as other sources of information to guide you in developing and carrying through on your training commitment.
In the war against childhood obesity, senior military leaders are taking a stand in the name of national security. The retired generals and admirals of “Mission: Readiness” are doing their part to combat childhood obesity by calling on Congress to remove junk food and high-calorie drinks from schools by adopting the Institute of Medicine standards for what can be served in schools, increasing funding for more nutritious meals, and supporting the development of public health interventions. The group is concerned that current school policies and lack of high nutritional standards are leading to unhealthy food choices in the form of vending machine snacks and sugary drinks. As much as 40% of children’s caloric intake occurs at school, so clearly schools have an important role to play. Retired U.S. Army General Johnnie E. Wilson points out that “We need America’s service members to be in excellent physical condition because they have such an important job to do.” The most recent report by the Mission: Readiness organization estimates that 27% of young Americans are still too fat to fight and not healthy enough to serve their country. In an analysis of military standards, being overweight was the leading medical reason for being rejected from the military between 1995 and 2008. While these military leaders may be fighting for your kids, the real battle begins at home. Encourage healthy eating and lifestyle behaviors by staying fit as a family.
