The New York Times reports in its “Well” blog on exercises that are helpful to reduce osteoporosis. The post says that “activities that involve impacts with the earth, such as running and jumping, are the most effective way to improve bone health,” specifically “sprinting and hopping.”
The post cites a study finding that “women ages 25 to 50 who leaped like fleas at least 10 times in a row, twice per day for four months, significantly increased the density of their hipbones.”
Meanwhile, other studies indicate that “weight training on its own does not seem to be an effective way to improve bone density,” though it appears to be more beneficial that “the no-impact sports of bicycling and swimming.”
The Nurses’ Health Study indicates that among “more than 60,000 postmenopausal women,” walking “briskly at least four times per week” appeared to reduce the risk of hip fractures.
