运动训练显著增强骨肌肉线粒体和毛细血管,适应主要取决于初始健身水平. 所有的训练类型,包括耐力训练 (ET),高强度间歇训练 (HIT) 和冲刺间隔训练 (SIT),都能产生可比的线粒体增长.
科学领域:
- 运动生理学和体育科学.
- 分子和细胞适应运动.
- 心血管和代谢健康.
背景情况:
- 骨肌肉的线粒体和毛细血管对于有氧健身至关重要.
- 降低水平与慢性和与年龄有关的疾病有关.
- 对于最佳运动训练建议的证据有限.
研究的目的:
- 为了比较耐力训练 (ET),高强度间歇训练 (HIT) 和冲刺间隔训练 (SIT) 对骨肌肉线粒体含量和毛细血管化的影响.
- 研究对最大氧气消耗 (VO2max),肌肉纤维大小和纤维类型比例的次要影响.
主要方法:
- 在PubMed,Web of Science和SPORTDiscus数据库中的系统文献搜索.
- 包括运动训练干预研究与线粒体或毛细管测量.
- 来自5973名参与者在353个 (线粒体) 和131个 (毛细血管) 文章中的数据的定量合成.
主要成果:
- 线粒体含量在ET (23%),HIT (27%) 和SIT (27%),无论年龄,性别或疾病,都同样增加.
- 每个纤维的毛细血管与ET,HIT和SIT相似增加;每毫米2的毛细血管与ET和HIT相似增加.
- 在所有训练类型中,VO2max同样增加,更高的频率和较低的初始健身与更大的收益相关.
结论:
- 线粒体,毛细血管和VO2max中的运动训练适应主要受到初始健身水平的影响.
- 适应运动能力在一生中保持不变,无论性别或疾病状况如何.
- 训练负载预测了线粒体和VO2max的变化,但它对毛细血管适应的影响不太清楚.

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...
