Limitations include self-reported recreational physical activity and
weight. However, the physical activity questionnaire used has shown good
reliability and validity,18,19 and physical activity in the present study has
shown expected associations with chronic disease outcomes.33-35 Selfreported
body weight also is highly correlated (r=0.96) with directly measured
weight in health professionals.21 We did not have detailed information
on other measures of body composition nor on medications potentially
affecting weight. Furthermore, participants are not representative of the US
population; however, their rate of weight gain was similar to that of comparably
aged women in the general population.8 Although we adjusted
for baseline diet, we did not have repeated measures of diet over time.
We also did not examine activity levels needed for weight management
among women restricting caloric intake because our intent was to investigate
women consuming a usual diet.
In conclusion, in this large prospective study of women consuming a usual
diet, sustained moderate-intensity physical activity for approximately 60
minutes per day was needed to maintain normal weight and prevent weight
gain. These data suggest that the 2008 federal recommendation for 150 minutes
per week, while clearly sufficient to lower the risks of chronic diseases,
is insufficient for weight gain prevention absent caloric restriction. Physical
activity was inversely related to weight gain only among normalweight
women; among heavier women, there was no relation, emphasizing the
importance of controlling caloric intake for weight maintenance in this
group.

Re: Physical Activity and Weight Gain Prevention
Running is a good exercise choice. If you want to reduce weight fast by releasing more sweat, do the running instead of walking.

Re: Physical Activity and Weight Gain Prevention
But a very poor choice for heavy people, if you are really oeverweight don't run, you will injure yourself and one thing that is very important in loosing weight or keeping a healthy weight is being able to stay active. So try to prevent getting injured at all costs.MarcellusBurright wrote:Running is a good exercise choice. If you want to reduce weight fast by releasing more sweat, do the running instead of walking.

Re: Physical Activity and Weight Gain Prevention
Wouldn't this study actually suggest that a "usual diet" is unusually abundant? What if the sample was regulars at an Old Country Buffet ... would the authors conclude that they should be exercising for 600 minutes per day to sustain a normal weight?
