Which of the following are benefits of regular physical activity for older adults? (Select all that apply.)
- AImproved balance and fall prevention✓ 正解改善平衡與預防跌倒
- BEnhanced cognitive function✓ 正解增強認知功能
- CIncreased bone density✓ 正解增加骨密度
- DHigher risk of cardiovascular complications較高的心血管併發症風險
- EBetter mood and reduced anxiety✓ 正解較佳的情緒與減少的焦慮
規律運動對於老年人的生理與心理健康至關重要。運動能強化肌肉力量與協調性，進而改善平衡，有效預防跌倒（Falls）。此外，運動能促進大腦血液循環，改善認知功能，並透過內啡肽（Endorphin）的分泌緩解焦慮與憂鬱情緒。承重運動（Weight-bearing exercise）如走路，能刺激骨細胞活性，增加骨密度，減緩骨質疏鬆的速度。運動本身是改善心血管健康的措施，而非增加併發症風險。
Regular exercise is essential for both the physical and mental health of older adults. Exercise strengthens muscle strength and coordination, which in turn improves balance and effectively prevents falls. In addition, exercise enhances cerebral blood circulation, improves cognitive function, and relieves anxiety and depression through the release of endorphins. Weight-bearing exercises such as walking stimulate osteoblast activity, increase bone density, and slow the progression of osteoporosis. Exercise itself is a measure that improves cardiovascular health rather than a source of additional complication risk.
