How much are you really exercising?
October 06, 2008People struggling with obesity often underestimate how many calories they are actually consuming, which can hinder weight loss efforts. It should follow that the same person would overestimate the amount of exercise they're doing, right?
Maybe not, say Temple University researchers. In a study to be presented at The Obesity Society's annual meeting, lead author Tracy Oliver, MEd, RD, LDN, a Lead Health Services Specialist at Temple's Center for Obesity Research and Education, found that obese women reported their activity levels most accurately, when compared to overweight and normal weight women.
Oliver compared the amount of activity reported by the women to the actual amount of activity as measured by an accelerometer, which is a device that measures movement and acceleration over the course of a year.
At the first measurement, and a second three months later, obese women most accurately reported the amount of physical activity they were getting. But at 12 months, all three groups were reporting on their activity levels more accurately.
"The ability to estimate the amount of minutes engaged in physical activity is a difficult task for many, however the accuracy of this estimate can increase with education and participation in physical activity over time," said Oliver.

Physical Activity Current Events and Physical Activity News RSSHome-based diet and exercise intervention improves elderly cancer survivors' physical function
A home-based program to improve exercise and diet led to significant, clinically meaningful improvement in body weight and physical function among older long-term cancer survivors in preliminary findings from the RENEW (Reach-out to ENhancE Wellness) trial.
Physical activity after bariatric surgery improves weight loss, quality of life
A new study by researchers from The Miriam Hospital's Centers for Behavioral and Preventive Medicine suggests increased physical activity after bariatric surgery can yield better postoperative outcomes.
UNC study: text messaging may help children fight off obesity
A new study from the University of North Carolina at Chapel Hill suggests that cell phone text messaging could be used to reduce children's chances of becoming overweight or obese later in life, by helping them monitor and modify their own behaviors now.
Brisk walk could help chocoholics stop snacking
Researchers at the University of Exeter have found that a walk of just fifteen minutes can reduce chocolate cravings. The benefits of exercise in helping people manage dependencies on nicotine and other drugs have previously been recognised. Now, for the first time, newly-published research shows that the same may be true for food cravings.
New MU Study Indicates that Exercise Prevents Fatty Liver Disease
It's easy to go to the gym on a regular basis right after a person buys the gym membership. It's also easy to skip the gym one day, then the next day and the day after that. A new University of Missouri study indicates that the negative effects of skipping exercise can occur in a short period.
Green neighborhoods may reduce childhood obesity
Childhood obesity can lead to type 2 diabetes, asthma, hypertension, sleep apnea and emotional distress. Obese children and youth are likely to be obese as adults, experience more cardiovascular disease, high blood pressure and stroke and incur higher healthcare costs.
Neighborhood greenness has long term positive impact on kids' health
In the first study to look at the effect of neighborhood greenness on inner city children's weight over time, researchers from the Indiana University School of Medicine, Indiana University-Purdue University Indianapolis and the University of Washington report that higher neighborhood greenness is associated with slower increases in children's body mass over a two year period, regardless of residential density.
Study: Elderly Women Can Increase Strength But Still Risk Falls
Elderly women can increase muscle strength as much as young women can, a new study from the University of New Hampshire finds, indicating that decline in muscle function is less a natural part of the aging process than due to a decline in physical activity.
Different psychosocial factors predict adoption, maintenance of physical activity program
The health benefits of regular physical activity are well documented, yet only 32 percent of adults in the United States engage in regular exercise. Now a new study by researchers at The Miriam Hospital offers some new insight into the role of social and environmental influences on physical activity behaviors.
Association found between severe obstructive sleep apnea
A study in the October 15 issue of the Journal of Clinical Sleep Medicine shows that unrelated to obesity, people with severe SDBs consume a more unhealthy diet, which may be a factor contributing to greater cardiovascular morbidity and mortality. These findings were most evident among women.
