概括

抵抗训练 (RT) 在两个月经周期 (MC) 中显著增加了肌肉截面面积 (CSA). 然而,CSA的个体变化表明RT之外的因素在这些周期中影响肌肉生长.

科学领域:

运动生理学运动生理学
生殖内分泌学生殖内分泌学

背景情况:

肌肉缩受各种生理因素的影响.
月经周期 (MC) 涉及荷尔蒙波动,可能会影响训练适应.
了解这些相互作用对于优化女性培训策略至关重要.

研究的目的:

研究抗力训练 (RT) 对肌肉横截面 (CSA) 在不同月经周期阶段的影响.
检查MC期间激素变化 (雌激醇和孕) 和肌肉CSA之间的关系.
为了确定RT诱导的肌肉适应在整个MC中是否一致.

主要方法:

一个主题内设计被使用的20名妇女有定期的MCs.
腿被随机分配到对照 (CON) 或RT条件.
肌肉CSA,雌激醇 (E2) 和孕激素 (P4) 在两个MC的月经 (M),排卵 (O) 和质 (L) 阶段进行测量.

主要成果:

与月经和排卵相比,黄质期的孕激素 (P4) 水平显著更高.
在MC阶段,雌激醇 (E2) 度没有显著差异.
在RT条件下,肌肉CSA在O2,L2和M3的基线 (M1) 显著增加,而CON条件没有显著变化.

结论:

抵抗训练可以在月经周期中引发肌肉CSA的显著增加.
虽然RT是主要的驱动因素,但肌肉CSA的个体变化表明其他因素可能有助于适应.
需要进一步的研究,以充分阐明激素波动和肌肉可塑性之间的相互作用.

Exercise and Muscle Performance

Exercise and Muscle Performance

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...

Smooth Muscle Contraction

Smooth Muscle Contraction

Smooth muscle contraction is a complex process vital for various bodily functions, from maintaining blood vessel tension to facilitating the movement of food through the digestive tract. Unlike striated muscles, smooth muscle contraction begins more slowly and lasts longer.
The onset of contraction is triggered by an increase in calcium ions within the sarcoplasm, similar to the process in striated muscle. However, smooth muscles have a relatively smaller reservoir of the sarcoplasmic...

Cross-bridge Cycle

Cross-bridge Cycle

As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.

Hormonal Regulation of the Menstrual Cycle

Hormonal Regulation of the Menstrual Cycle

The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Isotonic and Isometric Muscle Contractions

Isotonic and Isometric Muscle Contractions

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.
Isotonic contractions
Isotonic contractions occur when a muscle changes length while...

Fascicle Arrangement in Skeletal Muscles

Fascicle Arrangement in Skeletal Muscles

Fascicles are bundles of muscle fibers in a skeletal muscle. Muscle fascicle arrangement is directly associated with the power and range of motion of various muscles. The configuration of these fascicles can vary, leading to different functional outcomes.
The four primary types of muscle based on fascicle arrangement are:
