High Common Daily Activity Levels Reduce Risk Of Death

Wed, 12 Jul 2006 18:11:00 PST

Older adults who expend more energy through any daily activity, including non-exercise activity, have a lower rate of death than adults who are less active, according to a study in the July 12 issue of JAMA. Observational studies have shown that older adults who report low physical activity levels are at a higher risk of death compared with those who report moderate or high levels of activity. These findings have been based on questionnaires asking about physical activity levels, which may not be recalled accurately and are unable to account for many types of daily activity, according to background information in the article. Self-reported physical activity does not provide accurate estimates of absolute amounts of activity (kilocalories per day) and thus is less precise in determining whether higher levels of total activity-induced energy expenditure offer survival advantages.

STRRIDE trial: Exercise reverses unhealthy effects of inactivity

Sat, 03 Jun 2006 09:58:00 PST

Many of the detrimental effects of physical inactivity can be reversed, and in some cases improved, by a similar period of moderate exercise, Duke University Medical Center researchers have found in a new analysis of data from the first randomized clinical trial to evaluate the effects of exercise in sedentary overweight men and women. Just as important, the trial participants who exhibited the greatest decline in physical status during inactivity benefited the most from exercise training, according to the researchers. These findings linking the ability of exercise training to reverse the negative effects of inactivity can be attributed to the exercise alone, because the participants did not alter their diets during the trial, the researchers said.

Each Extra Hour of TV Translates Into 167 Extra Calories in Diet

The study results appear in the April 2006 issue of the Archives of Pediatric and Adolescent Medicine.
