The Claim
In obese older adults undergoing weight loss, aerobic exercise does not significantly reduce the loss of hip bone mineral density compared to weight loss without aerobic exercise.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In obese older adults losing weight, doing aerobic exercise does not prevent the loss of bone density in the hip compared to losing weight without exercise.
See the scientific wording
Aerobic exercise during weight loss in obese older adults does not significantly protect hip bone mineral density compared to no exercise, with hip BMD loss similar to that observed in weight loss alone, suggesting aerobic activity alone is insufficient to mitigate bone loss.
When an obese older adult loses weight, fat tissue shrinks and releases less leptin. Lower leptin causes bone cells to produce less protective protein that blocks bone breakdown, so bone-eating cells become more active and remove more bone. Aerobic exercise does not provide enough force on the hip bones to activate bone-building signals, so the bone loss from increased breakdown continues unchecked.
What the research says
1 studyThe study directly compared aerobic exercise to a control group and found no significant difference in hip BMD loss, and explicitly noted similarity to prior weight-loss-alone data. This supports the conclusion that aerobic exercise alone does not mitigate bone loss.
