概括
身体活动 (PA) 的强度和持续时间等维度与老年人可能发生的肉类 (PSA) 的风险较低有关,但中年人却没有. 特定的PA截止值可以帮助识别患PSA风险较高的人.
科学领域:
- 老年学是一门学科.
- 运动生理学 运动生理学
- 公共卫生 公共卫生
背景情况:
- 标志着肌肉质量损失和肌肉衰弱的萨尔科佩尼亚是老年人群日益关注的问题.
- 身体活动 (PA) 被认为是影响肌肉健康的关键可修改因素.
- 了解与肉症风险相关的PA的具体维度对于有针对性的干预至关重要.
研究的目的:
- 调查身体活动的各种维度 (强度,频率,持续时间,体积) 与中老年和老年人可能发生的肉症 (PSA) 之间的关联.
- 为确定不同人口群体中PSA风险的身体活动截止值.
- 探索PA和PSA之间的关系中的潜在的性别和年龄差异.
主要方法:
- 利用了来自2015年中国健康与退休长度研究的7,957名45岁以上成年人的数据.
- 使用修改的国际体育活动问卷简单表格评估体育活动.
- 根据测量肌肉强度和体力表现指标,定义了可能的肉类 (PSA).
主要成果:
- 对于男性来说,强烈强度的PA (≥3天/周,>10分钟/时间) 或总的PA (≥933次MET/周) 与较低的PSA风险相关.
- 对于女性来说,中等强度的PA (≥3天/周,>30分钟/时间),低强度的PA (≥6天/周,>120分钟/时间) 或总的PA (≥933次MET/周) 显示PSA风险降低.
- 参与强烈强度PA (≥1天/周,>30分钟/时间) 或达到总PA目标 (≥933MET/周) 的老年人 (≥65岁) 的PSA风险降低;中年成人 (45-64岁) 没有发现显著的关联.
- 接收器操作特征分析确定了PSA预测的PA截止值,男性为每周695次MET,女性为每周693次MET.
结论:

Exercise and Cardiac Output
1.1K
Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Exercise and Muscle Performance
1.5K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

The Effect of Aging on Tissues
2.2K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Exercise and Cardiovascular Response
874
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Changes in the Appendicular Skeleton with Age
2.1K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
