- AYoga瑜伽
- BSwimming游泳
- CBrisk walking or weight-bearing exercises✓ 正解快走或負重運動
- DStationary bicycling固定式腳踏車
— Explanation · 中文詳解 —
骨密度增加需靠「負重運動」（Weight-bearing exercise）。步行、爬樓梯或舉重能給予骨骼機械性壓力，刺激骨細胞增生（C）。游泳（B）與單車（D）屬於非負重運動，對心肺好但對骨密度增加效果有限。瑜伽（A）對柔軟度好但負重強度不足。
Increasing bone density requires weight-bearing exercise. Walking, stair climbing, or weight training provides mechanical stress to the skeleton and stimulates osteoblast proliferation (option C). Swimming (B) and stationary cycling (D) are non-weight-bearing exercises; they are beneficial for cardiopulmonary fitness but have limited effect on increasing bone density. Yoga (A) is good for flexibility but does not provide sufficient mechanical loading.
✦ 台美臨床差異
兩地復健科皆推廣負重運動，但美國臨床護理師常直接開立運動處方（Exercise Rx）。
