耐力运动 (EE) 显著改变了耐力运动员 (ET) 和对照 (CG) 的代谢物,影响了脂肪酸代谢和氧化防御. 抵抗运动 (RE) 主要在所有组中增加乳酸,这表明不同类型的训练对不同的代谢适应.
科学领域:
- 运动生理学 运动生理学
- 代谢学 代谢学 代谢学
- 生物化学 生物化学
背景情况:
- 对于训练有素运动员与久坐不动的人之间的运动诱导的代谢组适应的理解有限.
- 需要区分耐力训练和力量训练之间的反应.
- 代谢分析提供了对运动生理反应的见解.
研究的目的:
- 研究耐力运动员 (ET),力量运动员 (ST) 和久坐控制 (CG) 的运动诱导的代谢组适应.
- 为了比较耐力运动 (EE) 和抵抗运动 (RE) 对血代谢物的影响.
- 确定受不同训练方式和运动员状态影响的特定代谢途径.
主要方法:
- 在血样本上进行量化,有针对性的新陈代谢 (Biocrates MxP® Quant 500).
- 在12个ST,10个ET和12个CG中EE和RE前后的分析.
- 在三个不同的培训阶段结束时采集的样本.
主要成果:
- 在EE和RE后,乳酸 (Lac) 在所有组的运动后显著增加.
- 在CG和ET中,EE诱导了乙卡尼丁,阿拉基酸和docosahexaenoic酸的增加.
- 在EE后,ET显示了酸,酸,谷氨酸,六酸和松氨酸的独特增加;CG显示了甘油三酸的增加.
- RE主要增加了Lac;其他显著的代谢物变化在各组之间是最小的.
结论:
- 耐力运动 (EE) 在训练有素 (ET) 和未训练有素 (CG) 个体中显著影响脂肪酸代谢和氧化防御代谢物.
- 抵抗运动 (RE) 对代谢组的影响较为有限,主要是增加乳酸.
- 耐力训练可能会诱导能量代谢中的特定适应,从而导致ET中对运动的不同代谢反应.

Exercise and Muscle Performance
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
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...
