概括
七天Eurycoma longifolia Jack (ELJ) 补充剂没有显著影响橄球运动员在异常运动后的肌肉损伤,表现或激素水平. 草药补充剂对运动员进行艰苦的体力炼没有明显的益处.
科学领域:
- 运动科学 运动科学 运动科学
- 运动生理学 运动生理学
- 草药是一种草药.
背景情况:
- 欧利科马长叶 (Eurycoma longifolia Jack,简称ELJ) 已被公认为具有潜在的抗氧化和抗原特性.
- 奇特的运动会导致肌肉损伤,影响运动表现和恢复.
- 了解草药补充剂对运动引起的肌肉损伤的影响对运动员至关重要.
研究的目的:
- 研究ELJ补充剂对肌肉损伤标志物和奇特运动后的表现的短期影响.
- 评估ELJ对训练有素运动员唾液激素度的影响.
- 确定ELJ补充是否可以减轻运动引起的肌肉损伤并增强恢复.
主要方法:
- 18名训练有素的7人橄球运动员被随机分配到ELJ或安慰剂组.
- 参与者补充了400毫克/天的ELJ或安慰剂在异常腿部压力运动前七天.
- 肌肉损伤标志物 (肌酸激酶,疼痛),性能 (峰值力,功率,跳跃高度,RSI) 和唾液激素 (丸激素,皮质醇) 在运动后的多个时间点被测量.
主要成果:
- 在ELJ和安慰剂组之间,在执行异常收缩的数量方面没有发现显著差异.
- 唾液丸激素和皮质醇水平在补充后的两组保持不变.
- 虽然古怪的运动诱导了显著的性能下降 (峰值功率,跳高度,RSI) 和肌肉疼痛和肌酸激酶活性的增加,但ELJ补充剂与安慰剂相比没有显著改变这些标记物.
结论:
- 七天补充Eurycoma longifolia Jack (ELJ) 似乎不会显著影响经过训练的运动员在异常运动后的激素,表现或肌肉损伤标志物.
- 这些发现表明,在这些条件下,ELJ补充剂可能不会为遭受强烈偏心负荷的运动员提供性能或恢复优势.
- 用不同的剂量,持续时间或人群进行进一步的研究可能是有必要的,以充分阐明ELJ的潜在人体效应或恢复效应.

01:27Exercise 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...

01:20Exercise and Cardiovascular Response

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...

01:24Muscle 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...
