概括
年长的成年人可以提高肌肉的力量,强度和大小,每周只需进行一次古怪的抵抗训练. 这种最低剂量策略显示了与每周两次计划相似的结果,解决了对当前指南的不严格遵守问题.
科学领域:
- 运动生理学 运动生理学
- 老年学是一门学科.
- 肌肉生理学 肌肉生理学
背景情况:
- 在老年人中,遵守每周两次力量训练指南的程度较低.
- 众所周知,仅限于古怪的训练可以显著提高肌肉功能和大小.
研究的目的:
- 为了比较每周一次与每周两次异常训练对老年人肌肉功能和大小的影响.
- 为了确定最小剂量的异常训练策略是否可以有效地抵消与年龄相关的神经肌肉衰退.
主要方法:
- 36名老年人 (平均年龄~69岁) 被随机分配到对照组,每周一次或每周两次的古怪训练组.
- 训练涉及12分钟的会话,在最大偏心强度的50%下进行12周的训练.
- 肌肉力量,同度和偏心强度,以及巨大的侧面肌肉 (VL) 厚度在基线,中期和干预后被评估.
主要成果:
- 每周一次和两次的异常训练组都显示了肌肉力量 (13%),同位体强度 (17-36%),异常强度 (40-50%) 和VL肌肉厚度 (9-18%) 的显著改善.
- 据报道,肌肉疼痛最小,在每周两次的组中感知到的劳动力较低.
- 一次每周一次的疗程产生了与每周两次剂量相比可比的神经肌肉改善.
结论:
- 在老年人中,每周进行一次次最大异常阻力训练就足以改善神经肌肉功能.

Exercise and Muscle Performance
1.4K
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
2.1K
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...
