概括
中度至强度的体力活动 (MVPA) 与老年人中较高的相角 (PhA) 有关. 每天MVPA为19.7分钟可能有助于预测这个人群的高PhA.
科学领域:
- 老年学是指老年学的学科.
- 人体生理学 人体生理学
- 生物统计学 生物统计学
背景情况:
- 阶段角 (PhA) 是细胞完整性和营养状况的标志物.
- 身体活动对于保持老年人的健康至关重要.
- 在老年人群中,体力活动强度和PhA之间的关系需要进一步研究.
研究的目的:
- 为了研究相角 (PhA) 与社区居住的日本老年人体育活动强度之间的关联.
- 确定预测高PhA的体力活动的强度和持续时间.
- 探讨光强度体力活动 (LPA) 和中度至强度体力活动 (MVPA) 与PhA相关的作用.
主要方法:
- 这是一项涉及67名社区老年人的横截面研究 (平均年龄为78.3岁).
- 使用三轴加速度计来量化LPA和MVPA评估的体力活动.
- 使用Inbody S10测量身体组成和PhA,从右侧的身体测量计算PhA.
- 使用贝叶斯统计建模和接收器操作员特征曲线 (ROC) 分析.
主要成果:
- 在PhA和MVPA之间发现了显著的正相关性 (β = 0.256,p = 0.022).
- 在PhA和LPA之间没有观察到任何显著的关联 (β = -0.113,p = 0.341).
- 预测高PhA的最佳切断值为19.7分钟/天 (灵敏度=0.906,特异性=0.429).

01:17Factors Affecting Activity Coefficient
800
The extended Debye-Hückel equation indicates that the activity coefficient of an ion in an aqueous solution at 25°C depends on three partially interdependent properties: the ionic strength of the solution, the charge of the ion, and the ion size.
The activity coefficient value for an ion is close to one when the solution has almost zero ionic strength, i.e., when the solution shows close to ideal behavior. As the ionic strength of the solution increases from 0 to 0.1 mol/L, a...
