Exercise-prone mice put in a good 5 to 8 miles per day (the equivalent of an average man running 40 to 50 miles a day) vs. 0.3 miles per day for inactive mice. While the exercise wheels of the activity-prone mice would turn all night, some of the sedentary mice devised ingenious ways to avoid activity. One stuffed wood shavings around the wheel and turned it into a bed; one used it as an, ahem, toilet; and one climbed on top of her wheel only to get a better look at the overhead sensors tracking her movements...
This summer, part of the fund is being used to provide stipends to six Harvard undergraduates to provide six hours of individual tutoring per week to Allston-Brighton students...
...rule of thumb goes, the figures we got in our studies were that people using that standard earbud could listen at about 80% of maximum volume for 90 minutes per day or less without increasing their risk for noise-induced hearing loss. But the louder the volume, the shorter your duration should be. At maximum volume, you should listen for only about 5 minutes...
...through a two-year weight-loss program. The women were given free treadmills to use at home, regular group meetings and telephone pep talks to help keep them on track. Participants were also asked to restrict their food intake to between 1,200 and 1,500 calories per day, and were randomized to one of four physical activity intervention groups based on energy expenditure (either 1,000 calories or 2,000 calories burned per week) and exercise intensity (high vs. moderate). By the end of the 24-month intervention, the women who managed to lose at least 10% of their...
...beauty of this study is that we now have a target" - a better idea of how much exercise is needed for weight maintenance. There is, of course, some variation in how people respond. Some of the study participants fared well with less exercise than the additional 275 minutes per week (about 55 minutes per day, five days a week) that the study's author now recommends for weight maintenance. Others needed more. But the keys to success, according to Jakicic, were embracing the weight-loss program fully, and finding a way around the daily obstacles to exercising - that's something...
