冬季运动员高海拔训练没有改变心电图 (ECG) 模式与适当的营养. 然而,高海拔运动员的乳酸盐水平较高,特定的营养相关性影响心脏再极化.
科学领域:
- 运动医学 运动医学
- 环境生理学环境生理学
- 心脏病学 心脏病学
背景情况:
- 高空暴露可以影响心电图 (ECG) 参数.
- 这是一个很棒的节目,这是一个很棒的节目.
- 活着-低-火车-高
- 冬季运动员训练策略对心电图的影响尚不清楚.
研究的目的:
- 研究冬季运动运动员高空训练对心电图参数的影响.
- 为了比较运动员在高空与低空训练之间的心血管和生化标志物.
主要方法:
- 对102名冬季运动员的横截面研究,按训练高度分层 (高海拔:2500-3300米;低海拔:738米).
- 赛季中期的评估包括静止心电图,血压,血液生物化学和饮食回忆.
- 分析对高海拔和低海拔群体之间的ECG参数,乳酸和营养摄入量进行了比较.
主要成果:
- 在高海拔 (HA) 和低海拔 (LA) 组之间,心率,PR间隔或QTc没有显著差异.
- 高血压运动员表现出较高的缩血压,较短的QT间隔和较高的乳酸盐水平.
- 饮食分析显示脂肪,胆固醇,,和葡萄糖摄入量的差异;观察到特定营养素与心电图参数的相关性.
结论:
- 当营养摄入量足够时,间歇性高空训练不会改变冬季运动员的ECG模式.
- 增加的乳酸和营养相关性表明生理压力和电解质,维生素和矿物质在心脏再极化中的调节作用.

Factors Affecting Respiration
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...
