概括
在COVID-19流行病引起的炼后恢复综合运动训练改善了蛋白质水平,并部分恢复了老年人的身体功能. 这突显了持续体育活动对健康衰老的好处.
科学领域:
- 老年学和运动生理学
- 生物化学和临床化学
- 康复科学 康复科学 康复科学
背景情况:
- 由于COVID-19大流行,人们不得不突然停止定期的体育活动,导致老年人减轻炼.
- 了解运动中断和恢复对生理标志物和功能能力的影响,对于维持老龄人口健康至关重要.
- 众所周知,联合运动训练 (有氧和阻力) 对老年人有好处,但对与大流行有关的干扰的适应性不太了解.
研究的目的:
- 调查COVID-19相关的中断和随后恢复联合运动训练对身体活跃的老年人蛋白质概况,功能和身体能力的影响.
- 评估经过一段时间的脱离和重新开始运动后代谢和功能参数的恢复.
- 为了确定运动停止和恢复的反应中的潜在性别特异性.
主要方法:
- 研究了一组35名身体活跃的老年人 (平均年龄64.36岁).
- 在三个时间点收集了蛋白质水平,功能 (血清肌素,估计肌素清除量) 和身体功能 (定时启动和移动测试,步行速度,肌肉力量) 的数据:大流行前 (PRE),隔离12个月后 (PAN) 和恢复运动10个月后 (POST).
- 进行了统计分析,以比较三个时期的参数,重点关注性别差异.
主要成果:
- 与PRE和PAN相比,POST期间的老年男性和女性血清白蛋白和总蛋白水平显著增加.
- 年龄较大的女性表现出高血清肌素和定时升高测试值,与PRE相比,PAN和POST的估计肌素清除率下降.
- 与PAN和PRE相比,老年女性在POST中也表现出较低的步行速度和肌肉力量,而老年男性在恢复后表现出较好的标志物.
结论:
- 在停训期后恢复综合运动训练部分抵消了对老年人代谢和身体能力的负面影响.
- 研究结果表明,虽然与流行病相关的隔离引起的炼有可测量的影响,特别是在老年妇女的身体功能上,但恢复炼提供了部分恢复.
- 这项研究强调了老年人持续参与联合炼计划的重要性,以减轻阻碍效应并保持健康和功能独立.

3.9K
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...

01:19The Effect of Aging on Tissues
3.4K
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...

01:27Exercise and Muscle Performance
2.3K
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...

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.

01:29Bone Disorders
5.1K
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...

01:24Muscle Recovery and Fatigue
4.0K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...
