Fitness 2.0: Can social media help you get fit?

HPRC Fitness Arena:
More and more apps are supporting the goals of getting health and staying fit. Join them!

In 2008, the Journal of Medical Internet Research published an article titled Medicine 2.0: Social Networking,Collaboration, Participation, Apomediation, and Openness, in which the term “Web 2.0” is used. Web 2.0 refers to web applications that support collaboration and interactive information sharing online, a large part of which are the social media applications for blogging, wikis, and video streaming. The Journal article talks about the idea of a “Medicine 2.0” for web-based health and medical information, geared towards healthcare consumers, caregivers, patients, health professionals, and researchers.

Interestingly, all of this has given rise to a “Fitness 2.0” trend, allowing users to go beyond just the factual, static health information that exists and find more interactive information. It turns out that the internet can be a great resource for boosting one’s fitness level! YouTube, for example, has thousands of clips on exercise – proper techniques, expert advice – everything from the proper dead-lift technique to nutrition tips for weight loss.

These types of social media can also track fitness levels and goals of users by allowing them to enter in numbers and monitor their progress. Applications like Virtual Weight Loss, health networks like FitDay, and iPhone apps like “My Weight Loss Coach” are great ways to accomplish this. For an even simpler tracking method, use Twitter updates with a hash tag (i.e. #weightloss and #twit2fit) – a great way to get support while keeping a daily or weekly report of progress.

Another area where social media provides a bridge for exchanging health/medical information are online support/social communities. The sharing of experiences and struggles can help when things get tough or when motivation lags. With this level of personal interaction, users don't have to get healthy their own. Sites like Google Groups or DailyBurn, are easy ways to compare and discuss results with a community. When researching a health-related topic, however, keep in mind that blogs, videos, and social networks should not be primary sources of information. Look up multiple sources – no one source of information is ever perfect, so reduce the risk of bad information.

Social media is about creating connections and information, and healthy living is about consistency and knowledge. Together, they can be a great match. Social media can bring a lot of useful information and support to people looking to improve their health or fitness levels, and provides many innovative ways to stay motivated and well-informed.

Army revises training program to deal with overweight and unfit recruits

HPRC Fitness Arena:
The New York Times presents a look at the Army’s new physical-training program to deal with recruits who reach basic training having less strength and endurance than those privates in the past.

The New York Times August 31 edition presents a look at the Army’s new physical-training program to deal with  recruits who reach basic training having less strength and endurance than those in the past.  According to a Lt. Gen. who oversees basic training for the Army, “What we were finding was that the soldiers we’re getting in today’s Army are not in as good shape as they used to be”.  The cause of this decline, according to the article is a "legacy of junk food and video games, compounded by a reduction in gym classes in many high schools".

The article also cites the percentage of male recruits who failed the most basic fitness test at one training center rose to more than one in five in 2006, up from just 4 percent in 2000. Additionally, the article notes that the percentages were higher for women.

The new fitness regime tries to solve the problems of unfit soldiers by incorporating more stretching, more exercises for the abdomen and lower back, instead of the traditional sit ups, and more agility and balance training.

A strong country stays fit

HPRC Fitness Arena:
Why aren't there more of us out there exercising?

Research from the Harvard School of Public Health showed many years ago that individuals who exercise regularly die less from all causes. Although vigorous exercise, like running, produces greater gains, all that’s needed for good health is regular exercise. Regular physical activity has a positive effect on all of your body systems – it improves your mood and decreases anxiety, improves cognitive function, makes you stronger, and reduces your risk for many diseases like stroke, cardiovascular disease, many types of cancer, and adult onset diabetes. Even so, public health data from the Centers for Disease Control still shows that obesity and physical inactivity among adults in our country is high.

We at the Human Performance Resource Center are not only concerned with the total fitness of our Warfighters, but of all Americans. And like in many offices across the country, we work at desks, and fitness is something we have to carve out time for. But still, we do, as one of our staff members reports.

A few weeks ago, I went running with my super-tough Airborne Army son, a jumpmaster and SSG who’s been deployed many months over the last four years. When we last ran several years ago prior to his initial boot camp experience, I could outdistance him. Fortunately, that didn’t last long – six years and many runs later, this is no longer the case. The stories abound, and are hilarious. Like when he returned from his first 15-month deployment to Iraq: I had been running a lot and wanted to impress him with what good shape I was in. We hadn’t even made it out of my neighborhood, or hit the hills yet, and I was sucking wind. At that point he looked over and said, “Hey, Ma…we walkin’ or runnin’ today?” Fast forward to our five-mile run a few weeks ago in the midday July heat. I straggled back, having taken only a couple of one-minute walk breaks to catch my breath. Of course, he beat me back, and his greeting was, “Ma, you can do better than that!” But I know that underneath the teasing, he’s proud that his 50-year old mother is out that running with him, eating his dust. My response is, “Why aren’t there more mothers, sisters, brothers, fathers, sons, and daughters out here running with their Warfighter?”

So I challenge you: if we expect our Warfighters to be in optimal condition because their role, protecting our country, demands it – don’t we also have a responsibility to ourselves, our loved ones, and our country, to improve our health and reduce our healthcare costs? It doesn’t matter what you do to stay fit, only that you do something. Walk the dog, play outside with the kids, join an adult sports league, or go for a run – the possibilities are endless.

Sitting can be harmful for your health

HPRC Fitness Arena:
Couch potatoes – read on!

An American Cancer Society study found that individuals who sit more during their leisure hours and are less active, died sooner than those who sat less and were more active. According to researchers, "sit more, die more." If you are a couch potato, stand up and walk around! Get out and walk the dog, plant some flowers, or play ball with the kids… your own or the neighbor's!

Runners: To strech or not to stretch?

HPRC Fitness Arena:
The USA Track and Field (USATF), the National Governing Body for track and field, long-distance running and race walking in the United States has just released a study to determine the effect of pre-run stretching on running injuries.

The USA Track and Field (USATF), the National Governing Body for track and field, long-distance running and race walking in the United States has released a study to determine the effect of pre-run stretching on running injuries. The purpose of the study was to determine specifically if pre-run stretching of the three major leg muscle groups is beneficial for overall injury prevention or reduction.

According to the study, this was a clinical trial that involved close to 3,000 runners and the results confirm there is no difference in the risk of injury for those who stretched before running and those who did not. The study randomly assigned people to perform a specified pre-run stretching routine or to perform no pre-run stretching for a period of 3 months.

The findings of the stretch study can be viewed as a PDF here.

The power of muscle memory

HPRC Fitness Arena:
The number of hours a person spends pumping iron may make it easier to get back into shape and could also stave off weakness and decline in muscle function in old age. That's according to findings recently published in Proceedings of the National Academy of Sciences.

The number of hours a person spends pumping iron may make it easier to get back into shape and could also stave off weakness and decline of muscle function in old age.  That's according to findings recently published in Proceedings of the National Academy of Sciences.

In an interview with National Public Radio (NPR), Kristian Gundersen , one of the researchers of this study explains that muscles actually have a memory of their former strength — and that memory may last indefinitely. The article can be accessed here.

How do you find reliable health information online?

HPRC Fitness Arena:
Searching the internet for reliable health information.

Despite widespread access to internet-based healthcare information, there’s almost a complete lack of evidence showing any effects all this information may have on health outcomes. According to a study published in Health Expectations, this indicates that there’s a disparity between the health information we find online and our ability to use it properly.

So, with as much information as there is on the internet, how can we, as consumers, find reputable sources for our health questions? The internet can be a great resource when you want to learn about a specific disease or health condition. You can also find tips on staying healthy. But among the millions of websites that offer health-related information, many present myths and half-truths as if they are facts.

To avoid unreliable health information when you’re surfing the internet, use these tips to find reliable information:

  1. Keep in mind that anyone can publish anything they want on the internet, regardless of the facts. Ultimately, it’s up to the consumer to determine which information source is credible.
  2. In order to determine a trusted, verified source for credible and objective information, stick with well-respected health websites. A good starting point is healthfinder.gov, which provides a “Health A to Z” topic listing (http://www.healthfinder.gov/HealthAtoZ/ ) of over 1,600 health topics from the most trusted sources.
  3. Newspapers always use more than one source for verifying factual information. The same should hold true for health information. When searching a topic, it’s important to find at least a second reference to confirm your findings. Find a third reference, too, if possible. When several sources report similar information on a topic, it’s more likely to be accurate and up-to-date. In general, if you can't find the information duplicated in more than two or three references, then the information is questionable at best.
  4. Become skilled at separating facts from opinions. This can sometimes be difficult, as the evidence that exists may be minimal. It's important that you know the difference between fact and opinion, especially when you're researching treatment alternatives.
  5. Testimonials and personal stories tend to focus on a patient’s subjective point of view. If you find a website that quotes patients about the effectiveness of a treatment or therapy, this information is biased and cannot be trusted as a reliable source. However, there is information to be learned from the experiences of patients by using other sources (for example, through blogs and wikis, and support group message board forums). In those situations, refer back to point 1 (above) as your first line of review.
  6. Make sure the information you find is the most current available. Often, you will find that research and studies conflict with one another, or that newer information trumps older information.

Finally, information that you find on a website does not replace your doctor's advice. Your doctor is the best person to answer questions about your personal health. If you read something on the internet that doesn't concur with what your doctor has told you, make a point to speak with him or her about it.
