概括
这项研究发现,Ramanathan 4位方程式的平均加权皮肤温度 (Tmws) 是可以接受的在适度和温暖的条件下骑自行车. 配方之间的一致性在温暖的环境中更好.
科学领域:
- 环境生理学环境生理学
- 人类温度调节
- 运动科学 运动科学
背景情况:
- 计算平均加权皮肤温度 (Tmws) 存在多种公式,但它们之间的一致性不明.
- 准确的Tmws计算对于评估在不同环境中炼期间的温度调节反应至关重要.
研究的目的:
- 评估在稳定状态自行车运动中,五种常见的Tmws公式与12位标准公式 (Hardy-DuBois 12-site, HDB12) 的一致性.
- 在温和 (20°C) 和温暖 (30°C) 的环境条件下评估Tmws公式协议.
主要方法:
- 十名训练有素的男性参与者在20°C和30°C的环境中,在60分钟的时间内以55%的峰值氧气吸收率骑自行车.
- 使用HDB12,Hardy-Dubois7站点 (HDB7),Palmes/Park6站点 (PP6),Teichner6站点 (TEI6),Ramanathan4站点 (RAM4) 和Burton3站点 (BTN3) 的公式来计算Tmws.
- 使用平均偏差,平均绝对误差 (MAE),根平均平方误差 (RMSE) 和协议极限 (LOA) 来评估协议.
主要成果:
- 所有Tmws配方在温暖的条件下 (30°C) 与中度 (20°C) 条件相比,与HDB12有更好的一致性.
- 拉玛纳坦4位 (RAM4),伯顿3位 (BTN3) 和Teichner6位 (TEI6) 的公式表现最好.
- HDB7公式始终低估了HDB12,特别是由于干皮肤温度偏差.
结论:
- 在20°C和30°C条件下循环行驶时,RAM4公式是计算Tmws的可接受替代方案,而12位公式是不可行的.
- 与HDB12标准的配方一致性在运动期间在更温暖的环境中得到增强.
- 这项研究支持在研究环境中继续使用RAM4公式.

Body Temperature
4.0K
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Body Temperature
1.3K
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
Step 3: Adjust the patient’s clothing to expose only the axilla. It minimizes...

Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
