Active Voice: Responding to a NY Times Article That Missed the Point - "To Lose Weight, Eating Less is Far More Important Than Exercising More"
By John M. Jakicic, Ph.D., FACSM
Viewpoints presented in SMB commentaries reflect opinions of the authors and do not necessarily reflect positions or policies of ACSM.

John M. Jakicic, Ph.D., FACSM, is a professor and chair of the Department of Health and Physical Activity at the University of Pittsburgh in Pennsylvania. He also is director of the Physical Activity and Weight Management Research Center at the university. Extensively published and well-funded by NIH research grants, Dr. Jakicic’s specialization relates to health effectiveness of long- term strategies for successful weight loss in overweight populations. A particular focus in his work has been the role of physical activity in these interventions. Dr. Jakicic has served in numerous appointed and elected volunteer positions with ACSM. He currently is the chair of ACSM’s Strategic Health Initiative on Obesity. In the last few years, he also served on the American College of Cardiology/American Heart Association (ACC/AHA) Task Force on Practice Guidelines – a group of leading health scientists charged with developing and publishing four special reports in 2014 that address lifestyle management of risks for cardiovascular disease and overweight and obesity in adults.

Dr. Jakicic presents this invited commentary in response to an article recently published in the New York Times (NY Times). That article, by Aaron E. Carroll, M.D., was entitled
To Lose Weight, Eating Less is Far More Important Than Exercising More”. The NY Times is one of the foremost news sources in the world, having the largest circulation of any print newspaper in the US and having won more Pulitzer Prizes than any other news source. Therefore, the opinions expressed in the article by Dr, Carroll may influence understandings of a great many. For this reason, SMB is grateful to Dr. Jakicic for sharing an alternative viewpoint in this Active Voice commentary.More

USA Hosting 2015 World Medical Football Championships

The U.S. Medical Soccer Team (USMST) is currently hosting the 2015 World Medical Football Championships (WMFC) and Global Congress on Medicine and Health in Sport in Long Beach, California. The World Medical Football Championships is a week-long World Cup style soccer tournament comprised of physician teams from around the world brought together for friendly competition. The U.S. Medical Soccer Team is a partner of the Exercise is Medicine® program, a global health initiative of the American College of Sports Medicine.

In addition to the tournament, the Global Congress on Medicine and Health in Sport (GCMHS) will be held in conjunction with the WMFC. The goal of the congress is to bring physicians and other medical luminaries together to educate, innovate and improve the quality of care delivered to communities around the world. This year's congress will culminate in the first ever World Health Systems Symposium, which will be devoted to the global obesity epidemic.

Additionally, as part of this year's WMFC, a large event will be held to spotlight USMST's outreach program "Healthy, Fit and Smart" with more than 200 children from the local Boys and Girls Clubs located in and around Long Beach. The program is geared toward underserved youth and focuses on nutrition, fitness and education.

Screen Time Linked to Weaker Bones in Teen Boys
Teenaged boys who spend too many hours in front of the computer or television without participating in enough weight-bearing exercise could develop weaker bones as they age, a small Norwegian study suggests.

Childhood and the teen years are critical periods for growing bones and establishing a bone density level that can affect osteoporosis risk much later in life.

"We found a relationship between higher screen time and lower bone mineral density in boys," said Anne Winther, a physiotherapist at University Hospital of North Norway in Tromso and the study’s first author. "We are not able to detect causality with this study design, but it is likely that screen time is an indicator of a lifestyle that has negative impact on bone mass acquisition."

Among the 316 boys and 372 girls aged 15 to 19 years old, those who spent two to four hours, or more than six hours, in front of the screen every day tended to be slightly heavier than their peers who spent less time in front of screens. And boys overall spent more time in front of the computer and television than girls (five hours a day versus four).More

Bicycles Aren't Just for Kids
"Cycling is the new golf," The New York Times, CNN Money and The Economist have each declared while describing how bike rides are replacing tee times as a favorite pastime for business networking. And there's growing evidence that the group most strongly associated with golf — older adults and retirees — may be gripping handlebars as much as putters in the years to come.

Bicyclists age 50 and over pedaled an estimated 2.6 billion miles on 830 million rides in 2009 (the latest figures available), according to the U.S. Department of Transportation's National Household Travel Survey. That's way up from 1995 when people in that age group covered less than 400 million miles on 175 million rides. Bicycle riders age 70 to 79 alone made 147 million trips in 2009; those 80 and over took 13 million trips by bike.

Strong community connections have been shown to improve people's health and happiness, and cycling provides opportunities to meet fellow riders informally, or through cycling clubs. In Minnesota alone, there are more than 50 registered cycling clubs, some of them specially focused on older riders.

"The biggest jump we are seeing in biking is among older people," says Martha Roskowski, of the national organization PeopleForBikes. More
