概括
热适应显著降低了热不耐受性分类. 然而,不同的耐热性测试标准会影响分类率,特别是对于女性来说,这表明需要细致的评估.
科学领域:
- 环境生理学环境生理学
- 运动科学 运动科学
- 人类的适应能力
背景情况:
- 耐热测试 (HTT) 使用直肠温度 (Trec) 和心率 (HR) 来将个人分类为耐热 (HT) 或不耐热 (HI).
- 适应状态和性别对HTT分类标准的影响需要进一步研究.
研究的目的:
- 评估不同耐热性测试 (HTT) 标准在分类耐热性方面的有效性.
- 评估运动热适应 (HA) 和性别对HTT分类的影响.
主要方法:
- 40名参与者 (19M/21F) 在5天的异热运动热适应 (HA) 协议之前和之后接受了HTT.
- HTT涉及120分钟的跑步机测试,以5公里/小时-1的速度进行,2%的分数.
- 参与者根据预定义的Trec和HR值被分为HI或HT.
主要成果:
- 在HA后,热不耐受 (HI) 分类的整体率显著下降 (51.1%的PreHA降至23.6%的PostHA).
- 在各种标准中,女性在HA之前和之后都表现出比男性更高的HI分类.
- 基于Trec (ΔTrec (T120-T60) ≥0.45°C) 的平原的特定标准显示HA前和后的HI率一致,表明适应的敏感性.
结论:
- 运动热适应有效地降低了热不耐受性分类的速度.
- 现有的HTT标准可能会对个体进行差异性分类,女性更经常被归类为HI.
- 评估Trec高原的标准表明对热适应的敏感性,这表明其在评估适应时的实用性.

Responses to Heat and Cold Stress
14.9K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Toxicity Testing in Animals
16
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...

Temperature-Dependent Growth of Brook TroutThe growth of brook trout is closely influenced by water temperature. Experimental data demonstrate how trout weight changes over a 24-day period in response to varying water temperatures. At lower temperatures, such as 15.5 degrees Celsius, brook trout show significant weight gain. However, as the temperature increases, the amount of weight gained steadily decreases. At the highest temperature measured, 24.4 degrees Celsius, trout experience a net...

Requirements for Human Life
14.2K
The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Factors Influencing Microbial Growth: Temperature
1.4K
Microorganisms display remarkable adaptations, enabling them to thrive in diverse ecological niches across a wide range of temperatures. Temperature profoundly influences microbial growth by affecting enzymatic activity, membrane fluidity, and other cellular processes.Each microorganism operates within a specific temperature range defined by three cardinal points: minimum, optimum, and maximum. Below the minimum temperature, membranes lose fluidity, halting transport processes. Above the...
