負重運動（Weight-bearing exercise）如步行、慢跑、爬樓梯或舉重，能透過重力刺激造骨細胞增加骨密度。游泳雖為良好心肺運動，但因水浮力減輕體重，對骨質增加效果有限。年長者步行可同時促進平衡與骨骼健康，為最易推廣與執行的選項。
Weight-bearing exercises like brisk walking stimulate osteoblast activity, which helps increase bone density. Unlike non-weight-bearing activities such as swimming, walking applies necessary gravitational stress to the skeletal system, making it the most effective choice for promoting bone health in older adults.
✦ 台美臨床差異
美台皆強調肌力訓練與負重運動，台灣醫療體系較常鼓勵長者參與社區健走團體。
