概括

精英的开水游泳者在最大速度附近具有高的乳酸值 (LT). 在LT (SSLT) 的游泳速度是一个很好的性能预测指标,尽管4 mmol·L-1血中乳酸度 (SS4) 可能会高估女性有氧能力.

科学领域:

运动科学运动科学运动科学
身体生理学身体生理学
游泳表现分析游泳表现分析

背景情况:

乳酸值 (LT) 是耐力运动员的一个关键生理标志物.
在开放水域 (OW) 游泳者中评估LT对于优化训练和性能至关重要.

研究的目的:

在世界级OW游泳者中分析LT.
在LT (SSLT) 的游泳速度与4 mmol·L-1血乳酸 ([La-]; SS4) 的游泳速度进行比较.
检查SSLT和OW游泳表现之间的关系.

主要方法:

在50米池中分析了46个间歇增量试验的数据.
包括20名世界级和精英的男性和女性OW游泳运动员.
收集了400米,800米,1500米和10公里OW比赛的季节性最佳表现.

主要成果:

SSLT为男性的1.62 m·s-1和女性的1.46 m·s-1,接近峰值速度.
在男性中,SSLT和SS4之间没有显著差异 (P=.148).
在女性中,SSLT低于SS4 (P=.019),表明SS4高估了有氧能力.
SSLT与表现有负相关性,除了男性10公里和女性400米.

结论:

世界一流的OW游泳者拥有高度发达的有氧能力,LT接近最大速度.
在男性中,SS4可以接近SSLT,但在女性中高估了它.
更高的SSLT与更好的OW游泳性能有关,使LT成为一个有价值的评估工具.

Muscle Recovery and Fatigue

Muscle Recovery and Fatigue

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 Muscle Performance

Exercise and Muscle Performance

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...
