概括
每周累积至少300分钟的中度至强度体力活动 (MVPA) 可以显著改善老年人的身体功能和行走性能. 超过最低推的MVPA可以改善日常生活活动,降低医疗保健成本.
科学领域:
- 老年学和运动科学
- 公共卫生与老龄化问题
背景情况:
- 在老年人中,超过每周推的最低体力活动的健康益处尚未完全理解.
- 目前的指导方针建议每周至少进行150分钟的中度至强度体力活动 (MVPA).
研究的目的:
- 为了比较老年人的身体功能指标,积累150-299分钟/周的MVPA与积累≥300分钟/周的人相比.
- 为了研究更高的MVPA体积对老龄化人口的身体功能的影响.
主要方法:
- 193名老年人 (67±2岁) 根据每周的MVPA分为两组:150-299分钟 (体力活跃) 或≥300分钟 (高度体力活跃).
- 用手握强度,5次坐立测试 (5-STS),式跳跃和6分钟步行测试 (6MWT) 来评估身体功能.
- 通过加速度计测量MVPA;还记录了肌肉强化活动 (MSA),蛋白质摄入量和其他共变量.
主要成果:
- 积累了≥300分钟/周的MVPA的老年人表现显著改善了6分钟步行测试 (6MWT) 的表现和整体身体功能 (p<0.05).
- 在对MSA,性别,腰围和蛋白质摄入量进行调整后,这些改善仍然显著.
- 两组之间没有发现肌肉强度指标的显著差异.
结论:
- 在老年人中,坚持每周最少推MVPPA的两倍 (≥300分钟) 与增强的身体功能,特别是行走性能有关.
- 超过最低MVPPA指导方针支持日常生活活动,并可能减少身体残疾和相关医疗保健费用的负担.
- 虽然整体功能得到改善,但从更高的MVPA体积中获得的特定肌肉力量益处需要进一步调查.

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...

Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.

Exercise and Cardiovascular Response
870
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...

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.
Sustained exercise increases the muscles' oxygen demand, which can be...

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...
