概括
持续的抵抗训练是维持老年人肌肉质量的关键,无论它是不是.
科学领域:
- 老年学是一门学科.
- 运动生理学 运动生理学
- 营养科学 营养科学
背景情况:
- 衰老导致肉症,其特点是肌肉质量和力量的损失.
- 抵抗训练和蛋白质补充剂是抵消与年龄相关的肌肉衰退的策略.
- 最佳的培训模式 (家庭培训与中心培训) 和继续培训的影响需要进一步研究.
研究的目的:
- 为了比较家庭用乳清蛋白 (LITW) 进行光强度训练与中心用乳清蛋白 (HRTW) 进行重阻力训练在老年人肌肉质量和力量保护方面的有效性.
- 评估持续抵抗训练对肌肉质量,力量和功率的影响,而不是在1年干预后停止.
- 为了确定家庭培训是否与长期肌肉维护的中心培训一样有效.
主要方法:
- 104名健康的老年人 (>65岁) 参与了为期一年的干预:LITW,HRTW或仅 whey 蛋白 (WHEY).
- 肌肉质量,力量和功率在干预结束时和干预后6个月被测量.
- 参与者被分为在随访期间继续抵抗训练 (CONT) 和停止 (STOP) 的人.
主要成果:
- 在6个月的随访期间,在LITW,HRTW和WHEY组之间没有观察到肌肉质量,强度或功率变化的显著差异.
- 继续抵抗训练 (CONT) 与停止 (STOP) 相比,与四头骨横截面区域的更好保存有关.
- 继续训练并没有显著影响肌肉强度或功率的变化.
结论:
- 在老年人中,家庭抵抗训练并不优于中心训练来保持肌肉质量和力量.
- 持续的抵抗训练对于保持肌肉质量至关重要,无论最初的训练干预措施如何.
- 虽然仅仅补充蛋白质是不够的,但将其与持续的抵抗运动相结合,对于老年人的肌肉健康至关重要.

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...

Longitudinal Research
12.0K
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...

Bone Disorders
3.7K
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...

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...

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...
