More evidence that there are health benefits from physical activity, even minimal amounts. Ohio State University researchers found that physical activity, even 10 minute at a time physical activity or exercise, adds up and is associated with lower amounts of cardiovascular (heart) disease in the next ten years - even for obese and overweight persons.
Being overweight or obese are risk factors for cardiovascular disease, type 2 diabetes, hypertension, and cancer. About 40% of Americans are obese and 32% are overweight, so having a way to simply and cheaply lower rates of cardiovascular disease is wonderful. Overweight is body mass index (BMI) of 25.0 to 29.9, obesity is BMI 30 or higher, and normal BMI is 18.5 to 24.8 (see CDC guidelines)
The researchers found that physical activity is more important than weight of a person in determining the risk of cardiovascular disease over the next 10 years. Unfortunately 43% of the overweight participants and 53% of the obese participants reported being sedentary (did not engage in at least 10 minutes of continuous physical activity each week) - and these groups had the highest risk of cardiovascular disease.
What counts as exercise or physical activity? Physical activity should be at least 10 continuous minutes or more, and ideally add up to 150 minutes or more each week. All moderate (e.g. brisk walking, light yard work, vacuuming, dancing) and vigorous (e.g. jogging, swimming laps, aerobics, heavy yard work) recreation activities count. The study found that engaging in less than 150 minutes a week also lowered the risk for cardiovascular disease, just not as much as for those with 150 minutes or more each week.
Government guidelines: The Physical Activity Guidelines from the US Department of Health and Human Services recommends that adults do at least 150 to 300 minutes of moderate-intensity physical activity a week, or 75 to 150 minutes of vigorous-intensity activity, or an equivalent combination of moderate- and vigorous-intensity activity.
Bottom line: Try to move, move, move as much as possible! Yes, a nice 20 minute (1 mile) walk counts!
From Medical Xpress: Not much exercise needed to lower heart disease risk for overweight people
A new study suggests, for obese or overweight adults, that any amount of exercise might lower the risk of developing cardiovascular disease in the next 10 years. ...continue reading "Any Amount of Physical Activity Is Good For Overweight Adults"
