Aerospace medicine and human performance
|October 3, 2025
概括
耐力和抵抗训练的女性在运动期间对热应激有类似的生理和感知反应. 训练背景不会显著改变这些活跃女性的耐热性.
科学领域:
- 运动生理学 运动生理学
- 环境生理学环境生理学
- 运动科学 运动科学 运动科学
背景情况:
- 对热应激的性别特异性反应仍未得到充分描述,特别是在具有不同培训背景的女性中.
- 了解受过培训的女性的温度调节对于制定有效的热安全指南至关重要.
研究的目的:
- 调查和比较耐力训练 (ET) 和抵抗训练 (RT) 妇女在炎热中对中等强度运动的生理和感知反应.
- 为了确定训练背景是否影响女性的耐热性和运动压力.
主要方法:
- 一项交叉研究涉及17名热不适应的女性 (8ET,9RT) 在高温 (33°C) 和中性 (21°C) 条件下在60%V·o2峰值下进行75分钟的步行炼.
- 关键的生理测量包括直肠温度 (Trec),心率 (HR) 和每分钟通风 (V ̇e). 使用感知劳动 (RPE) 和热感觉尺度等级来评估感知反应.
主要成果:
- 与中性相比,ET和RT女性在热状态下表现出明显升高的Trec,HR,V ̇e和感知应变.
- 在ET和RT女性之间没有发现Trec,HR,V ̇e或感知等级的显著差异.
- 虽然RT女性在运动后的热量中乳酸酸含量较高,但这与感知到的更高的炼或症状无关.
结论:
- 耐力训练和抵抗训练的女性在高温运动中经历了相似的生理和感知应变.
- 训练刺激,而不是最大的氧气吸收 (V ̇o2峰值),似乎在温度调节结果中更有影响.
- 耐热性建议应包括不同训练学科的活跃女性.

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
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...

Introduction to Stress and Lifestyle
512
Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...
