Impact matters for bone health, but jumping is only one way to create it, and the research in postmenopausal women is not nearly as convincing as the social media trend suggests. In younger, premenopausal women, daily jumping has increased bone density at the hip. But when a similar protocol was studied in postmenopausal women, there was no increase in bone density after 12 months, even though the women followed the program more consistently and generated more force. That makes the risk-benefit equation important. Jumping requires you to repeatedly leave the ground and absorb the landing. That brings in landing mechanics, joint stress, balance and fall risk, all of which can become more relevant when someone already has low bone density, arthritis, reduced strength or concerns about fracture. In one study reviewed here, postmenopausal women actually generated greater ground-reaction forces than younger women, raising questions about how effectively that force was being absorbed. So if the bone-density benefit is uncertain, adding a movement with more joint and landing demands may not be the best place to start. Heel drops offer another way to create impact without leaving the ground. Force-plate studies have measured them at roughly 2.5 to 5× body weight, depending on the population and technique. And we have longer-term heel-drop data in postmenopausal women. Heel drops have been associated with maintaining bone density over 12 months, and in one 2-year study of women with osteopenia or osteoporosis, 75% maintained bone density and 45% of the group gained bone density. When traditional impact isn’t appropriate, whole body vibration at the right settings can provide a simulated impact stimulus without jumping or a hard landing. The takeaway: for osteoporosis and osteopenia, the goal is not to chase the hardest impact possible. It’s to create an appropriate mechanical stimulus while also considering joint health, balance, fall risk and fracture risk. You do not have to jump to load your bones. #bonehealth #osteoporosis #osteopenia #bonedensity #healthyaging
