概括
与非使用者相比,第二代口服避孕药 (OC) 使用者在经过12周的抵抗训练后,在特定的手臂和腿部肌肉中表现出更大的肌肉生长. 然而,力量的增长在各组之间是相似的.
科学领域:
- 运动生理学 运动生理学
- 内分泌学 在内分泌学.
- 运动科学 运动科学
背景情况:
- 口服避孕药 (OCs) 被生育年龄的女性广泛使用.
- 对OCs对骨肌肉适应抵抗训练的影响仍然不完全理解.
- 研究激素对肌肉缩的影响对于优化训练方案至关重要.
研究的目的:
- 为了比较第二代口服避孕药 (OC) 使用者和非使用者在结构化抵抗训练计划后的肌肉缩.
- 评估两组之间瘦组织质量和肌肉特异性生长的差异.
- 为了评估力量发展的潜在变化.
主要方法:
- 进行了为期12周的抵抗训练干预.
- 参与者包括年轻,未受过培训的女性:14名OC使用者和12名eumenorrheic非使用者 (NOC).
- 肌肉厚度 (超声波),身体成分 (DXA) 和最大关节扭矩在干预前后都被测量.
主要成果:
- 经合组织使用者手臂肌肉质量显著增加 (10.5%与6.6%相比).
- 在OC使用者的三个特定肌肉群中,高性增长更为明显 (4.5%-7.9%对1.5%-3.1%).
- 在OC使用者和非使用者之间没有观察到最大强度增加的显著差异.
结论:
- 第二代OC使用与特定肌肉群的增强肌肉缩和抵抗训练期间更大的手臂瘦组织增加有关.
- 这些发现表明,与OC使用相关的荷尔蒙因素可能会影响肌肉生长,而不依赖于力量发展.
- 需要进一步的研究来阐明驱动这些差异性肌肉适应的潜在生理机制.

Exercise and Muscle Performance
2.2K
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...

Isotonic and Isometric Muscle Contractions
6.4K
Two primary types of muscle contractions are isotonic and isometric, each serving unique functions and involving distinct mechanisms. Both isotonic and isometric contractions are integral to the body's complex system of movement and stability. Isotonic exercises contribute significantly to functional strength and movement, while isometric contractions are crucial for maintaining posture and joint stability.

Muscle Contraction
8.7K
In skeletal muscles, acetylcholine is released by nerve terminals at the motor endplate—the point of synaptic communication between motor neurons and muscle fibers. The binding of acetylcholine to its receptors on the sarcolemma allows entry of sodium ions into the cell and triggers an action potential in the muscle cell. Thus, electrical signals from the brain are transmitted to the muscle. Subsequently, the enzyme acetylcholinesterase breaks down acetylcholine to prevent excessive...

Hormonal Control of the Ovarian Cycle
6.3K
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Muscle Stimulation Frequency
4.2K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.
