概括

年龄较大的成年人.

科学领域:

老年学是指老年学的学科.
行为科学行为科学
公共卫生公共卫生

背景情况:

对于老年人来说,体育活动 (PA) 干预措施通常具有有限的效果.
改变健康行为干预措施经常忽视时间变化的行为决定因素.
了解时间依赖因素对于开发动态的PA干预措施至关重要.

研究的目的:

调查能力,机会,动机和行为 (COM-B) 的决定因素之间的个人内部关联.
检查这些关联与老年人客观测量的体力活动 (PA).
通过生态瞬间评估 (EMA) 来评估决定因素和PA之间的时间关系.

主要方法:

64名健康的老年人 (平均年龄为72.1岁) 参加.
生态瞬间评估 (EMA) 调查问卷每天进行6次,以捕捉情绪,疲劳,意图和自我效能.
手腕加速度计 (Axivity AX3) 客观测量了PA;进行了多级回归分析.

主要成果:

在刺激,丧,意图和自我效能之间发现了积极的关联,随后轻度至中度至强度的PA.
随着随后的PA,观察到放松,满意度和疲劳的负面关联.
这些关联在EMA触发后15分,30分,60分和120分钟显而易见.

Longitudinal Research

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Factors Influencing Heart Rate

Factors Influencing Heart Rate

The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

Factors Affecting Activity Coefficient

Factors Affecting Activity Coefficient

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...
