Daily 24-h accelerometer data, collected continuously for 10 years, were categorized into activity quartiles. Final lean mass was greater for the third activity quartile (men and women with respective mean counts of 7,800 and 7,700 steps/day or mean duration of exercise at >3 metabolic equivalents (METs) of 20 and 17 min/day) than for the first and second quartiles. A proportional hazards model predicted that, over the 10 years, men and women in the two lowest activity quartiles (<6,700 and <6,800 steps/day) were 2.3 and 3.0 times as likely, respectively, to be sarcopenic as those in the highest activity quartile (>9,000 and >8,400 steps/day). Likewise, men and women with <16 and <14 min/day, respectively, of activity >3 METs were 3.0 and 3.5 times as likely to develop sarcopenia as those with >28 and >22 min/day. The risk of developing sarcopenia was substantially lower in elderly people taking at least 7,000-8,000 steps/day or exercising for at least 15-20 min/day at >3 METs.

连续收集了10年的每日24小时加速度计数据被归类为活动四分位数。第三个活动四分位数(男性和女性的平均步数分别为7800和7700步/天，或代谢当量(MET；3)运动的平均持续时间分别为20和17分钟/天)的最终瘦身质量大于第一和第二个四分位数。一个风险比例模型预测，在这10年中，活动量最低的两个四分位数(每天6,700步和6,800步)的男性和女性产生骨肉的可能性分别是活动量最高的四分位数(每天9,000步和8,400步)的2.3倍和3.0倍。同样，每天运动16分钟和14分钟的男性和女性患骨质疏松症的可能性是每天运动28和22分钟的男性和女性的3.0倍和3.5倍。老年人每天至少步行7,000-8,000步或在大都会艺术博物馆锻炼至少15-20分钟，患骨质疏松症的风险要低得多。
