运动员在运动期间血压压缩/代谢等效 (SBP/MET) 斜率较高的运动员表现出心脏壁厚度增加和运动能力降低. 这一群人也面临着晚年患高血压的更高风险.
科学领域:
- 心脏病学 心脏病学
- 运动医学 运动医学
- 运动生理学 运动生理学
背景情况:
- 工作负载指数的缩血压对运动的反应 (SBP/MET斜率) 是评估身体活动期间异常血压反应的新参数.
- 了解运动员SBP/MET斜率的临床意义对于风险分层至关重要.
研究的目的:
- 调查SBP/MET斜率与正常压力运动员的临床/心脏维度参数之间的关联.
- 评估SBP/MET斜率对运动员未来心血管事件的预测价值.
主要方法:
- 一组292名正常压力奥林匹克运动员接受了临床,心声和运动压力测试.
- 系统性血压/代谢等效 (SBP/MET) 斜率在最大运动期间计算.
- 为了进行比较分析,运动员根据SBP/MET斜率分为四分之一.
主要成果:
- 较高的SBP/MET斜率四分位数与左心室间隔膜 (IVS) 厚度增加相关.
- 在较高的SBP/MET斜率四分位数中的运动员有减少的运动能力 (W/Kg),并且主要是男性.
- 在10.3年的随访期间,在最高SBP/MET斜率四分位数中的运动员中,显著比例 (13.6%) 患有高血压.
结论:
- 运动员SBP/MET斜率升高与心脏壁厚度增加和运动能力降低有关.
- 较高的SBP/MET斜率是增加左心室壁厚度和减少运动能力的独立预测因素.
- SBP/MET斜率可以作为运动员患晚期高血压风险的有价值指标,需要进一步的长期研究.

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...

Sustained exercise increases the muscles' oxygen demand, which can be...

Hormonal Regulation of Blood Pressure
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction...

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
