Active Voice: Children Spend Most of their Time in Sedentary Behavior
By Jonathan A. Mitchell, Ph.D.    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.

Jonathan A. Mitchell, Ph.D., is a Postdoctoral Fellow at the University of Pennsylvania. He is funded on a Ruth L. Kirschstein National Research Service Award. His research focus includes sedentary behavior epidemiology. He is particularly interested in studying the amounts of time youth spend in sedentary behavior and if high levels of sedentary behavior are independently associated with health outcomes. In the June issue of Medicine & Science in Sports & Exercise® (MSSE), he and his co-investigators presented findings of a prospective study of sedentary behavior patterns and socioeconomic correlates in children ages 12-16.

Being physically active is beneficial to children’s health and development, and children are recommended to spend at least one hour per day in moderate-to-vigorous-intensity physical activity (MVPA). However, consider a hypothetical child who meets this guideline and sleeps for nine hours per day. This child has 14 waking hours remaining in his/her day that could be spent in either light-intensity physical activity or sedentary behavior. Few research studies have quantified the time children spend in sedentary behavior during their waking hours and this served as motivation for our recent study, published in MSSE, which describes levels of sedentary behavior in a cohort of children at ages 12, 14 and 16. The children wore activity monitors at each age for one week, except when they were asleep or when they were participating in water activities (bathing or swimming). We found that the children at age 12 spent approximately 54% of their monitored time in sedentary behavior, and this increased to approximately 65% of their monitored time at age 16. We also found that the children experienced fewer breaks in their sedentary behavior from age 12 to 16. To accommodate the increase in sedentary behavior, we found that time spent in light-intensity physical activity decreased from age 12 to 16 (with little to no change in MVPA).

Actiheart - Ambulatory Energy Expenditure Monitor

The Actiheart is the gold standard for ambulatory measurement of energy expenditure, having been validated against DLW. Combining activity and heart rate measurement in one discreet unit, it is possible to measure AEE in daily living for up to 21 days. The Actiheart can also record HRV data.

Q&A with Olympic Torchbearer Steve Blair

Prominent scientist carries the flame, explains ‘The Kiss’

Steven Blair, P.E.D., FACSM, long has illuminated the connections between physical activity and health. On July 11th, he literally took up the torch for the cause, serving as an official torchbearer for the London Olympics as James Pivarnik, Ph.D., FACSM, had done for the 2008 games. SMB caught up with Dr. Blair after his service as a Torchbearer.

SMB: What did you find surprising or unexpected about the experience?

BLAIR: I was really impressed with the number of people and the enthusiasm they exhibited. There must have been thousands of people on the street over the ~5 km course that was the route of the group of which I was a part. The crowd consisted of infants in arms to very elderly people in wheelchairs. There were many school groups, from elementary to high school students. Many of the kids had Olympic Torches they had made.

SMB: How does carrying the torch relate to your lifelong study of physical inactivity?

BLAIR: I think I was given the opportunity to participate in the Torch Relay because of my research on physical activity and health. I am grateful that work in this area was recognized.

Policy Corner: UNICEF Begins to Tackle NCDs in Children and Adolescents
   Share    Share on FacebookTwitterShare on LinkedinE-mail article
The historic Side Event on Physical Activity and Non-Communicable Diseases, which ACSM convened last fall before the UN High-level Meeting on NCDs, brought into sharp focus the significance of physical inactivity as a global health risk.

Advocates continue to draw attention to the connection between active lifestyles and health. According to a recent post on the Dialogue4Health blog sponsored by the Public Health Institute, UNICEF—the UN agency devoted to children’s health and welfare—will add information on non-communicable diseases in the upcoming revision of its “Facts for Life” handbook.

ACSM Joins the Olympics Buzz—What's Your Role?
Share   Share on FacebookTwitterShare on LinkedinE-mail article
The London Olympics are just around the corner, and ACSM is gearing up to play its part. The Olympic Games take place July 27-August 12, and the Paralympic Games run Aug. 29-Sept. 9. We anticipate a surge of media inquiries and lots of interest from the general public in topics relating to athlete health, sports performance, fitness and conditioning.

These games have been dubbed the Social Media Games or "socialympics” and are anticipated to be the most liked, tweeted, and tagged sporting event in history. ACSM’s Olympics communication program will embrace the momentum of the social media movement—and there are multiple ways you can have a role:
  • If you are an ACSM Fellow, have expertise in an area related to the Olympics, and are great at explaining science in a clear, simple manner, we'd love to discuss how you can share your insights with the media. Perhaps you can augment (and eventually join) the ACSM Media Referral Network, a volunteer panel of physicians, researchers, educators and certified professionals who are available for the interview requests and inquiries we receive from the media. Please contact publicinfo@acsm.org to learn more.
  • Are you a diehard Olympics fan? Please help us identify hot topics, intriguing controversies and expert insights to highlight on the ACSM website and across our social media platforms. Share your ideas on our Facebook page or contact Annie Bell at abell@acsm.org.
  • Join the conversation! We will be tweeting and posting right alongside Olympians, fans and everyone else. Please Follow us on Twitter and Like us on Facebook to participate in the discussions and share your thoughts. We especially encourage students to join in.

Importance of Exercise In Health plans upheld by Supreme Court decision
Medical News Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
According to scientists and medical experts, even though the U.S. Supreme Court's decision on the Affordable Care Act (ACA) anticipated much speculation while putting plans into effect, it still does not change one important thing they are sure of. Leaders of the American College of Sports Medicine (ACSM) strongly believe physical activity and exercise to be the most powerful tool in helping aid the sick people in the U.S.There is widespread support in Congress for a plan to help prevent disease instead of helping people pay for treatment after they get sick, including promotion healthy lifestyles and physical activity.

Janet Walberg Rankin, Ph.D., ACSM president and an associate dean at Virginia Tech, quoted a U.S. Department of Health and Human Services announcement that physical inactivity will have caused about 7 million premature deaths in the country just in this decade.

Bouncing back from fitness injuries
Today's Diet and Nutrition    Share    Share on FacebookTwitterShare on LinkedinE-mail article
You think you’re pretty fit. You exercise regularly, eat right, and make sure your body is getting the vitamins and minerals it needs to perform at its best. But that doesn’t make you immune to injury. Trained athletes suffer fitness injuries all the time. You could be susceptible, too, and perhaps you’ve already suffered back pain or a sprained ankle during the course of your exercise program.

So what do you do to bounce back? Doctors and physical therapists agree that you need to give yourself time to heal. But that doesn’t mean giving up exercise in the meantime. It does mean taking care of yourself, however, and sometimes the best thing you can do for an injury is evaluate how it happened in the first place.
