Brief, but intensive bouts of exercise equally effective for losing weight
Washington: A new research has revealed that for preventing weight gain, the intensity of the activity matters more than duration.
University of Utah researchers found that even brief episodes of physical activity that exceed a certain level of intensity can have as positive an effect on weight as does the current recommendation of 10 or more minutes at a time.
It was suggested that taking the stairs, parking at the far end of the lot, and walking to the store or between errands are choices that can add up and can make a positive health difference.
Subjects for the study were drawn from the National Health and Nutrition Examination Survey, NHANES, and participants from 18 to 64 years of age were drawn from the database.
Researchers compared measurements of physical activity based on length of time and intensity. Four categories were created: higher-intensity bouts (greater than 10 minutes exertion at greater than 2,020 counts per minutes, or CPM), higher-intensity short bouts (less than 10 minutes at greater than 2,020 CPM), lower-intensity long bouts (greater than 10 minutes and less than 2,019 CPM), and lower-intensity short bouts (less than 10 minutes and less than 2,019 CPM).
The study used body mass index, BMI, to measure weight status.
Results showed that when women each 5-feet-5-inches tall were compared, the woman who regularly adds a minute of brisk activity to her day will weigh nearly a half-pound less. Results were similar for men.
Importantly for both, each daily minute of higher-intensity activity lowered the odds of obesity - 5 percent for women, and 2 percent for men.
In a new study was published in the American Journal of Health Promotion.
