概括
高负荷耐力训练比低负荷训练更能提高力量,但这两种方法都产生了类似的肌肉厚度增加. 丸激素和皮质醇等激素标志物在不同组之间没有显著变化,表明可比的恢复.
科学领域:
- 运动生理学 运动生理学
- 运动科学 运动科学 运动科学
- 生物医学科学 生物医学科学
背景情况:
- 调查了高负荷与低负荷阻力训练辩论,以优化力量和增高.
- 探索与不同训练负载相关的生理机制,包括运动单元的招募.
- 研究了训练强度对肌肉生长和力量适应的影响.
研究的目的:
- 为了比较高负荷 (85% 1-RM) 和低负荷 (30% 1-RM) 阻力训练对肌肉厚度,强度和荷尔蒙标记的影响,超过9周.
- 确定在娱乐训练的男性中高负荷和低负荷训练方案之间的适应的显著差异.
主要方法:
- 17名休训练的男性参与了研究,分为高负荷 (n=8) 和低负荷 (n=9) 组.
- 两组每周完成三次全身抵抗训练,持续9周,重复到失败.
- 肌肉厚度 (双臂,三臂,大胸,大腿直肠,双腿) 和唾液激素 (,皮质醇) 在基线和每三周测量一次.
主要成果:
- 随着时间的推移,在所有测量地点都观察到肌肉厚度的显著增加 (p < 0.05),除了三腕 (p = 0.04),没有显著的分组时间相互作用.
- 两组之间没有发现基底激素水平或急性运动后激素反应 (,皮质醇) 的显著变化 (p > 0.059).
- 与低负荷组相比,高负荷组在一次重复的最大 (1-RM) 强度上显著增加.
结论:
- 使用高负荷或低负荷的阻力训练会导致类似的肌肉缩.
- 高负荷训练对于增强最大力量增长 (1-RM) 是优越的.
- 两种训练负载都没有显著改变基本或急性运动后丸激素和皮质醇水平,这表明类似的生理应激和恢复反应.

Types of Hormones
83.1K
Hormones can be classified into three main types based on their chemical structures: steroids, peptides, and amines. Their actions are mediated by the specific receptors they bind to on target cells.

Hormonal Regulation
35.8K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Plant Hormones

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Classification of Skeletal Muscle Fibers
59.4K
Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

Binary Acids and Bases
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...
