概括
在受过训练的个体中,增加阻力训练体积并没有增强肌肉生长或增强力量,而不是维持基线体积. 这两种训练方法在肌肉厚度和1RM强度方面都产生了类似的结果.
科学领域:
- 运动生理学 运动生理学
- 肌肉适应 肌肉适应
- 阻力训练 阻力训练 阻力训练
背景情况:
- 了解最佳的训练量对于最大限度地提高肌肉缩和力量至关重要.
- 之前的研究表明,训练量和适应之间存在剂量反应关系,但训练过的个体的最佳水平仍在争论中.
研究的目的:
- 为了比较增加训练量 (ITV) 与维持基线训练量 (BTV) 对以前训练过的成年人的肌肉适应的影响.
- 为了确定与基线相比,处方更多套药物是否会增加肌肉厚度和强度,而不是维持基线体积.
主要方法:
- 42名经过抵抗训练的成年人参加了为期12周的研究.
- 每位参与者的手臂被随机分配到增加训练量 (ITV) 或基线训练量 (BTV) 条件中.
- 干预前后测量了肘部 flexors 的肌肉厚度和一次重复最大 (1RM) 强度.
主要成果:
- 在所有测量位置 (上臂距离的50%,60%和70%) 中,在ITV和BTV条件之间没有观察到肌肉厚度变化的显著差异.
- 与对照组相比,ITV和BTV条件都显示肌肉厚度和1RM强度显著增加.
- 没有证据表明,与维持基线体积相比,增加训练量导致肌肉厚度或1RM强度的优越增长.
结论:
- 与基线相对增加的训练量没有增加肌肉适应 (肌肉厚度,1RM强度) 与保持基线训练量相比在休训练的个体中.
- 增加训练量和维持基线训练量协议在促进显著的肌肉适应方面同样有效.
- 这些发现表明,训练有素的人可能不需要逐步增加训练量,以继续获得肌肉大小和力量.

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...

Exercise and Cardiovascular Response
739
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...

Exercise and Cardiac Output

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...

Muscle Stimulation Frequency
2.0K
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.

At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...

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
3.2K
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...
