概括
在受过训练的男性中,增加30%或60%的抵抗训练量并没有比保持体积更大的肌肉生长. 然而,30%的增加组显示出强度耐力改善,这表明肌肉适应的最佳体积存在.
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
- 肌肉适应 肌肉适应
背景情况:
- 渐进的超负荷是抵抗训练 (RT) 肌肉缩和力量的基石.
- 为了最大限度地提高已经训练有素的个体的适应能力,最佳的每周设置量仍在争论中.
- 了解RT量和适应之间的剂量-反应关系对于有效的培训计划至关重要.
研究的目的:
- 调查与对照组 (CON) 相比,每周增加30% (G30) 和60% (G60) 的RT设置体积对训练有素男性肌肉缩和力量的影响.
- 为了确定较高的RT体积是否会导致训练有素的人群中优异的肌肉适应.
- 确定RT体积的潜在值,以最大限度地增加肌肉和力量.
主要方法:
- 55名经过抵抗训练的男性被随机分为三个组:CON (保持先前的体积),G30 (+30%体积) 和G60 (+60%体积).
- 参与者完成了为期8周的下体RT计划,每周执行两次.
- 测量包括大腿肌肉厚度,感兴趣区域的无脂肪质量,一次重复最大 (1RM) 和重复到失败 (RTF) 在1RM的70%时.
主要成果:
- 所有组都显示肌肉厚度和无脂肪质量显著增加,CON,G30和G60之间没有显著差异.
- 所有组都提高了1RM强度,但CON组表现出最强的整体1RM.
- 只有G30组表现出重复到失败 (强度耐力) 的显著增加,而G60组显示下降.
结论:
- 训练有素的个体可以实现显著的肌肉缩和力量增加,而无需大幅增加每周的RT体积超过一定的值.
- 较高的RT量 (例如,60%的增加) 可能不会优越,并可能会损害训练有素的男性的最大力量增长.
- 适度增加RT体积 (30%) 可能会增强强力耐力,这表明"更多并不总是更好"用于优化训练群体的肌肉适应.

Exercise and Muscle Performance
1.3K
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...

Exercise and Cardiac Output
919
Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
Sustained exercise increases the muscles' oxygen demand, which can be...

Exercise and Cardiovascular Response
734
Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Muscle Recovery and Fatigue
2.0K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

Regulation of Stroke Volume
3.1K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Cardiac Output II: Effect of Stroke Volume on Cardiac Output
674
Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...
