概括
阻力训练中的逐渐超负荷,无论是增加负载还是重复,都同样提高了初学者肌肉的力量和大小. 这两种方法都有效地促进新手学员的肌肉力量和横截面积 (CSA) 的增长.
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
- 人类表现的人类表现.
背景情况:
- 渐进的超负荷是抵抗训练的基石,用于肌肉的适应.
- 实施渐进式超负荷的最佳方法 (例如,增加负载与重复) 仍然是最大限度地提高训练结果的兴趣主题.
- 了解这些差异对于为初学者设计有效的培训计划至关重要.
研究的目的:
- 为了比较两个不同的渐进式超负荷策略对肌肉强度和横截面积 (CSA) 的影响.
- 研究是否增加训练负载 (LOADprog) 或增加重复 (REPSprog) 在未受过训练的年轻成年人中产生更好的结果.
- 为初学者提供基于证据的阻力训练进展建议.
主要方法:
- 在39名未受过培训的年轻成年人 (20名男性,19名女性) 中,采用了主体内实验设计.
- 参与者的腿被随机分配到负载进展 (LOADprog) 或重复进展 (REPSprog) 协议中,持续10周.
- 通过腿部延伸一次重复最大 (1RM) 来测量肌肉力量,并使用超声波测量Vastus lateralis CSA.
主要成果:
- 无论是LOADprog还是REPSprog协议,都导致1RM强度和vastus lateralis CSA从训练前到训练后显著增加.
- 在1RM改善方面,在LOADprog和REPSprog组之间没有观察到统计学上显著的差异.
- 同样,在两种进展方法之间没有发现关于肌肉CSA增加的显著差异.
结论:
- 通过增加训练负载或增加重复,逐步超载同样有效地提高未经训练的年轻人的肌肉力量和肌肉缩.
- 这两种策略都为在抵抗训练的早期阶段实现肌肉质量和力量的初步增长提供了可行的途径.
- 这些发现表明程序设计的灵活性,允许个人根据偏好或可访问性选择进展方法.

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
812
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
2.1K
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...

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...
