Too cold for exercise?

Don’t let cold weather deter you from your fitness goals.

As winter approaches here in the northern hemisphere, staying active requires more planning to be safe and comfortable. Here are some tips for exercising in cold weather conditions:

  • Since medical conditions such as Raynaud’s, cardiovascular disease, and asthma can be exacerbated by climate changes, be sure to check with your doctor before exercising in the cold.
  • Check out these tips from the Mayo Clinic, which include dressing in layers that include a synthetic material such as polyester or polypropylene close to the skin (avoid cotton, since it soaks up the sweat!) and paying close attention to your extremities, especially your fingers and toes, since the circulation to these areas decreases in cold weather.
  • The American College of Sports Medicine also has a Position Stand on preventing cold-weather injuries during exercise that emphasizes being able to recognize the signs and symptoms of hypothermia and frostbite, as well as monitoring wind-chill temperature. The signs and symptoms of hypothermia can vary, but in general watch for feeling cold, shivering, apathy, and social withdrawal. Also watch for the early stages of frostbite (which precede the deep frostbite that can cause major tissue damage) in which you’ll feel burning, numbness, tingling, itching, or cold sensations.

If you pay attention to these guidelines, you can continue to stay fit all winter long.

Operation Bushmaster

Operation Bushmaster, a field training exercise for medical students, reminds us that both physical and mental performance are key aspects of success for military healthcare practitioners.

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.

Training Warfighters for optimal mental performance

Stress as part of combat preparation—can you take the heat?

Understanding how stress affects you both mentally and physically in high-stress situations is important for optimal performance—which is why training under stress is a central part of combat preparation. Knowing what your reactions are, when to pause and take a deep breath, how to use positive self-talk, when to recalibrate one’s physical responses, and how to recharge (sleep and proper nutrition) after a stressful event are key for being at your peak mental performance. Getting support from comrades and using appropriate humor also can help relieve stress.

One-Rep-Max calculator

Use this easy tool to determine your one-repetition maximum before you begin a strength-training program.

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.

Suspension training: Put some suspense in your workout

Suspension training is a popular way to get a good workout wherever you are with very little equipment, using just your body weight for resistance.

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.

MHS highlights Total Force Fitness

July was the Military Health System’s “Total Fitness Month.” HPRC offers lots of resources to follow up on their recommendations for healthy living.

This past July, the Military Health System focused on promoting Total Force Fitness, giving priority to seven top areas: tobacco-free living, drug-abuse prevention, healthy eating, active living, injury-free and violence-free living, reproductive and sexual health, and mental and emotional well-being. They suggest managing your own health and wellness by making healthy choices between doctor’s visits. For inspirations and ideas that can help, check out HPRC’s ways to:

When it comes to performance—you booze, you lose

Going out for a drink to celebrate after a long race or a tough workout may be good for the soul, but it’s bad for performance.

Before you reach for a cold one, consider that drinking alcohol before, during, or after exercise can be detrimental to your performance, especially when consumed in excess. The effect of alcohol on skeletal muscles has been found to decrease strength output and can cause muscle cramps, pain, and loss of proprioception. Alcohol can also negatively affect your metabolism during exercise and contribute to dehydration. There is a shortage of data on the effects of alcohol on a recovering athlete, but some studies have shown that alcohol slows the recovery process by impacting muscle growth and repair systems. While current research has shown that alcohol in moderation can have other health benefits, it may be better to save that drink for when your physical performance is not on the line. There is also a growing body of research investigating the effects of combining alcohol with energy drinks. Many energy drinks contain substances and supplements that can interfere with normal alcohol metabolism and impair judgment. Be a conscious consumer and know what kinds of ingredients may be risky for your health.

U.S. Army reinstates basic fitness requirement to take PME courses

If you want to earn credit for PME courses, first you must pass the APFT and meet weight requirements.

Beginning on November 1st the U.S. Army will bring back the requirement to pass the Army Physical Fitness Test, including weight standards, in order to enroll in professional military education courses. Initially this requirement was waived due to the great demand for soldiers during OIF and OEF. Sgt. Todd McCaffrey states, "Reestablishing the Army physical fitness test and height/weight standards into our professional military education programs reinforces the efforts the Army's senior leaders have been emphasizing on standards based training and education." For information on how to meet these requirements, visit HPRC’s Fighting Weight Strategies, service-specific Physical Fitness Guides, and Policies, Standards, Reports, and Guidelines.
