預防骨質疏鬆的關鍵在於刺激骨骼進行重塑(Remodeling),這需要透過「負重運動」(Weight-bearing exercise)來達成。當肌肉收縮與地心引力作用於骨骼時,能刺激骨細胞(Osteoblasts)活動,增加骨密度。快走(Walking)是簡單且有效的負重運動。游泳與水中有氧雖對關節負擔小,但因水的浮力抵消了體重,對骨密度的刺激效果有限,不屬於預防骨質疏鬆的負重運動。
Weight-bearing exercises like walking apply stress to bones, stimulating osteoblasts to increase bone density and prevent osteoporosis. Non-weight-bearing activities such as swimming do not provide sufficient mechanical loading because water buoyancy supports body weight.
