With Exercise, Length Doesn’t Matter
Can you really keep in shape with ten minutes of exercise a day? Researchers at Boston University think so, especially if you throw in a lot of housework, done vigorously. BU Today reports on the research, for which scientists attached accelerometers (motion detectors) to more than 2,000 people for eight days. The researchers found that 56 percent of the men and 47 percent of the women met their exercise quota of a 150 minutes per week. Some met the quota with the prescribed 10-or-more-minute exercise sessions, and the average subject met the quota with significant amounts of activities that were shorter than 10 minutes. Their exercise ranged from the vigorous (hiking, jogging, sports, shoveling, and farm work) to the moderate (brisk walks, heavy cleaning, and sports like badminton and golf). The bottom line: the length of workouts didn’t matter, but all of those who exercised 150 minutes a week had smaller waists, lower body mass index, better cholesterol, and lower triglycerides than subjects who didn’t complete the weekly exercise quota.
