概括
通过感知劳动力 (RPE) 的评分来衡量内部负荷,与专业排球运动员的训练强度 (压力和跳跃) 有很强的相关性. 这表明,训练持续时间对于感知到的劳动力来说不如高冲击运动那么重要.
科学领域:
- 运动科学 运动科学 运动科学
- 生物力学 生物力学
- 运动生理学 运动生理学
背景情况:
- 了解内部和外部训练负载之间的关系对于优化表现和预防精英运动员受伤至关重要.
- 排球训练涉及许多跳跃和动态运动,需要仔细监控球员的运动.
研究的目的:
- 为了评估在职业男排运动员练习前和练习后反运动垂直跳 (CVJ) 强力时间指标的变化.
- 调查训练期间内部负载 (感知劳动力评分 - RPE) 和外部负载变量 (压力,跳跃,活跃分钟) 之间的相关性.
主要方法:
- 十名男排精英球员在训练前和训练后在强力板上进行了CVJ.
- 使用惯性测量单元 (VertTM) 测量外部负载,以捕获应力,跳跃和活动分钟.
- 在实践后使用Borg CR-10评估感知劳动力 (RPE) 尺度来评估内部负荷.
主要成果:
- 在CVJ力-时间指标中没有发现显著的前后实践差异.
- 在RPE和压力 (r = 0.713) 和RPE和跳跃 (r = 0.671) 之间观察到强烈的正相关性.
- 在RPE和Active Minutes (r = -0.038) 之间发现了一个微弱的,不显著的相关性.
结论:
- 职业排球的内部训练负载似乎更受运动强度 (高冲击动作和跳跃数量) 的影响,而不是训练的总持续时间.
- 这些发现可以为教练提供监测训练负载的信息,强调特定运动类型对球员力的影响.

Muscle Recovery and Fatigue
2.2K
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...

Fatigue
213
Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

Fatigue Strength of Concrete
223
Fatigue, in the context of materials science and engineering, refers to the weakening or failure of a material caused by repeatedly applied loads, even if these loads are below the strength limit of the material. Fatigue strength in concrete is a critical property that influences its durability and longevity. Concrete can fail in two ways due to fatigue. Static fatigue or creep rupture occurs under a constant load or one that increases slowly. The other failure mode is due to cyclical or...

Disorders of the Skeletal Muscle
999
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Exercise and Muscle Performance
1.5K
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...
