Comprehensive Soldier Fitness adds to the roster of total force fitness programs

HPRC Fitness Arena:
The Army’s CSF program—now adapted for the Air Force, Navy, Marines, DoD civilians, and families—provides another avenue to total force fitness.

True total force fitness and overall well-being are crucial to Warfighter readiness and success, and awareness of this is now spreading like wildfire. Admiral Mullen’s Total Force Fitness Initiatives center on the importance of mind, body, family, and environment for overall Warfighter resilience.

There are numerous programs within the military designed to support and enhance Warfighter resilience – some unit specific and some branch or joint-service specific. The HPRC is in the process of gathering information on these myriad programs and highlighting those that are clearly evidence-based, that highlight the importance of mind-body integration, and that teach Warfighter-relevant skills and strategies for performance optimization.

Last week we added a section in our Total Force Fitness domain on the Comprehensive Soldier Fitness (CSF) program. We describe the program, give step-by-step information about  its components, and highlight where to go for more information and program participation.

To give you a brief overview, CSF is an integrated Total Force Fitness (TFF) resilience-building program developed by the Army in collaboration with researchers in positive psychology and resilience building. CSF is designed to give Warfighters, their families, and their communities the knowledge, skills, and behaviors to “thrive in their lives” and successfully adapt to life’s challenges. Consistent with some of the components of Total Force Fitness identified by the DoD, CSF has five basic sectors: physical, social, emotional, spiritual, and family.

CSF was initially developed for the Army community, but it has now been adapted for use by the Air Force, Navy, and Marines. In addition, CSF provides training tools specifically designed for family members. Most of the training materials require AKO/DKO access, but the main exception is the family member materials, which are available for immediate download (with registration).

We hope that this new area of our website will be useful, help foster resilience in all, and provide a one-stop shop for previewing some resilience programs ongoing within the military.

Get 7-8 hours of sleep to perform daily tasks efficiently

HPRC Fitness Arena:
More than one-third of adults in the U.S. Don't get enough sleep, and getting less than 7 hours will impact even your everyday tasks.

According to a recent article in the Morbidity and Mortality Weekly Report, the National Sleep Foundation reported that more than one-third of adults in the United States are not sleeping enough, and inadequate sleep impairs daily tasks. Compared to those who reported sleeping 7-8 hours regularly, those who slept less than 7 hours reported significantly more trouble performing the daily tasks such as:

  • Ability to concentrate
  • Memory
  • Working on a hobby
  • Driving or taking public transport
  • Taking care of financial matters
  • Performing at work.

Sources of dark green vegetables

HPRC Fitness Arena:
“Dark green vegetables” are an important component of a healthy diet, but what vegetables other than broccoli are in this class?

We’re supposed to eat a lot of dark green vegetables, but beyond broccoli, what are some good options? For starters, pick a salad that has romaine or dark green leafy lettuce. Bok choy, collard greens, kale, mustard greens, spinach, turnip greens, and watercress are all good dark green vegetables that contain lots of nutrients. Variety is the key to an overall healthy diet, so don’t forget to include some dark green vegetables in your daily diet.

Monitor your physical performance using your heart rate

HPRC Fitness Arena:
Your heart is the key to effective training. Learn how to monitor it during exercise to achieve the optimum results from your training program.

Monitor your heart rate to ensure that you are training in the appropriate range for your performance needs. This simple practice will help you track the way your body responds to training to effectively optimize your physical performance. The American Council on Exercise (ACE) has information on how to monitor your exercise intensity using your heart rate, as well as an online tool for calculating your target heart rate. A similar online calculator is available from the Army’s Hooah 4 Health website.

Navy fitness through NOFFS

HPRC Fitness Arena:
This Navy fitness program focuses on basic and performance nutrition alongside physical training exercises designed to target operational tasks and reduce injuries.

The Navy Operational Fitness and Fueling Series (NOFFS) provides the Navy with "best in class" physical fitness and nutrition performance information for both Sailors and Navy health and fitness professionals. NOFFS instructs individuals on how to train effectively and safely and how to make healthy nutrition choices in both shore-based and operational environments.

Based on worldwide mission requirements, which require the Navy to intensity its operational tempo, it’s imperative for Sailors to be physically fit. Physical fitness is an essential component of operational readiness and the ability to meet deployment schedules. Sailor resiliency and durability are the primary goals of the development and distribution of NOFFS.

The purpose of NOFFS is to provide a complete physical training program that will eliminate the guesswork for:

  • The individual Sailor who is participating in his/her personal physical training program
  • The Navy health and fitness professional who is interested in obtaining a ready-made comprehensive and biomechanically balanced individual or group physical training program.

    The goals of NOFFS are to:

    • Improve operational performance
    • Provide basic and performance nutrition guidance.
    • Decrease the incidence and severity of musculoskeletal injuries associated with physical training.

      NOFFS provides Sailors with an evidence-based performance tool that will address injury prevention by physically training the movement patterns of operational tasks. Rather than focusing specifically on the physical readiness test (PRT), NOFFS emphasizes how to specifically improve the functional performance of a Sailor during daily operations. This includes lifting, pushing, pulling, carrying, aerobic/anaerobic demands, and body movement skills requiring balance, agility, and coordination. The focus of the project is to optimize operational physical performance and fueling for Sailors while preserving Navy combat power.

      Food dyes and hyperactivity: Is there a link?

      HPRC Fitness Arena:
      In the debate over food dyes and hyperactivity in children, the FDA feels there is not enough evidence to support any action.

      Red 40, Yellow 5, Yellow 6, and other dyes are artificial colorings allowed in foods in the U.S., yet there is a long-standing debate over whether food dyes contribute to hyperactivity in children. The Food and Drug Administration’s (FDA) Food Advisory Committee met the last week of March and determined that there is not enough evidence to support the link between food dyes and hyperactivity in children. For now, there will be no warning labels on food products containing dyes.
