Physical activity when young provides lifelong benefits to cortical bone size and strength in men

Abstract

Significance: Bones adapt to mechanical forces in youth to increase their size and strength but are more at risk for breaking later in life. Do the skeletal benefits of physical activity in youth persist with aging? Here we show at an upper extremity site that half of the benefit in bone size and one-third of the benefit in bone strength obtained from physical activity during youth are maintained throughout life, even though the bone mass benefits are lost. When physical activity was continued during aging, some mass and more strength benefits were preserved. These data suggest that physical activity during youth should be encouraged for lifelong bone health, with the focus being optimization of bone size rather than increasing mass.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
