背景情况:
- 生物衰老可能受到生活方式因素的影响,包括身体活动.
- 表观遗传衰老加速 (EAA) 作为生物衰老的生物标志物.
- 了解体育活动对EAA的长期影响对于促进健康衰老至关重要.
研究的目的:
- 调查12年身体活动 (PA) 轨迹与表观遗传年龄加速 (EAA) 之间的关系.
- 在中年和老年人中随着时间的推移识别体育活动的不同模式.
- 确定不同类型的体力活动 (剧烈,中度,轻度) 与EAA有不同的关联.
主要方法:

Aging

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

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...
