直肠温度 (Trec) 和胃肠温度 (TGI) 的测量显示了被动加热和恢复期间的显著差异. 在恢复期间,Trec和TGI之间的协议不那么有利,无论冰泥的摄入情况如何.
科学领域:
- 运动生理学 运动生理学
- 热调节 热调节 热调节
- 运动科学 运动科学 运动科学
背景情况:
- 精确的核心体温监测在运动和热应激研究中至关重要.
- 直肠温度 (Trec) 是核心体温的常见代理值,但其在各种条件下与胃肠温度 (TGI) 的一致性仍在争论中.
- 调查被动加热和回收干预措施 (如冰泥摄入) 对温度测量协议的影响对于实际应用很重要.
研究的目的:
- 在被动加热和随后恢复期间比较直肠温度 (Trec) 和胃肠温度 (TGI).
- 检查冰泥摄入对Trec和TGI在被动加热后恢复过程中的协议的影响.
- 在这些特定的实验条件下,评估Trec作为TGI的替代品的可靠性.
主要方法:
- 12名健康的男性通过热水浸泡被动加热,以提高Trec大约1.8°C.
- 在加热后,参与者在环境条件下经历了60分钟的恢复期.
- 在康复期间,参与者摄入冰 (ICE) 或控制饮料 (CON),并持续监测Trec和TGI.
主要成果:
- 在被动加热过程中,Trec始终低于TGI (P < 0.001).
- 在康复期间,Trec变得高于TGI (P < 0.001).
- 在恢复阶段与加热阶段相比,Trec和TGI之间的协议在恢复阶段不那么有利,在恢复阶段对ICE和CON条件观察到更广泛的协议限制 (LoA).
结论:
- 在被动加热和随后的恢复过程中,直肠温度 (Trec) 和胃肠温度 (TGI) 呈现出显著的差异.
- 在恢复阶段,Trec和TGI之间的协议是减少的,而不管冰泥的摄入.
- 在从被动热应激中恢复期间,Trec可能不是TGI的始终可靠的指标,在这种情况下,使用Trec作为核心体温的唯一测量标准时,建议谨慎使用Trec.

Glass-bulb Thermometer:
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,...
