概括
耐力训练可以增强大脑的血液流动,增加向前额皮层的氧气输送. 这项研究表明,训练改善了大脑两半球的氧化,每个半球都有不同的适应性.
科学领域:
- 运动生理学 运动生理学
- 神经科学是一个神经科学.
- 运动科学 运动科学 运动科学
背景情况:
- 最佳的大脑功能依赖于足够的血液和氧气供应.
- 了解耐力训练如何影响大脑氧化,对于性能优化至关重要.
研究的目的:
- 研究结构化耐力训练计划对向右和左前额皮层输送氧气的影响.
- 在8周的训练干预后,评估大脑氧化标记物的变化.
主要方法:
- 16名男子长途跑者接受了为期8周的训练计划,将高强度间歇训练和持续训练相结合.
- 在训练前和训练后测量VO2max.
- 功能近红外光谱学 (fNIRS) 在亚最大循环过程中评估了前额叶皮质,横向大脑和双臂肌的氧化 (氧化血红蛋白,脱氧化血红蛋白,总血红蛋白,组织和指数).
主要成果:
- 在跑步和骑自行车后训练中,VO2max显著增加.
- 在亚最大运动期间,在右前额叶皮层和左前额叶皮层观察到氧化标志物 (O2Hb,HHb,THb) 的显著增加.
- 组织和指数 (TSI) 在左前额皮层下降,而活跃肌肉 (横向巨) 显示氧化减少,不活跃肌肉 (双臂) 显示氧化增加.
结论:
- 耐力训练促进血液体积从外围肌肉再分配到大脑,增强大脑的氧气供应.
- 右前额叶皮和左前额叶皮表现出对耐力训练的不同适应,这表明它们在耐力训练中扮演着不同的角色.
- 这些发现突出了大脑对耐力运动的适应能力及其对体力运动期间认知功能的潜在影响.

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...

Lateralization
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.
