Infrared thermography (IRT) is a non-invasive tool to measure the body surface radiation temperature (Tsr). IRT is an upcoming technology as a result of recent advancements in camera lenses, detector technique and data processing capabilities. The purpose of this review is to determine the potential and applicability of IRT in the context of dynamic measurements in exercise physiology. We searched PubMed and Google Scholar to identify appropriate articles, and conducted six case experiments with a high-resolution IRT camera (640 × 480 pixels) for complementary illustration. Ten articles for endurance exercise, 12 articles for incremental exercise testing and 11 articles for resistance exercise were identified. Specific Tsr changes were detected for different exercise types. Close to physical exertion or during prolonged exercise six recent studies described "tree-shaped" or "hyper-thermal" surface radiation pattern (Psr) without further specification. For the first time, we describe the Tsr and Psr dynamics and how these may relate to physiological adaptations during exercise and illustrate the differential responsiveness of Psr to resistance or endurance exercise. We discuss how bias related to individual factors, such as skin blood flow, or related to environmental factors could be resolved by innovative technological approaches. We specify why IRT seems to be increasingly capable of differentiating physiological traits relevant for exercise physiologists from various forms of environmental, technical and individual bias. For refined analysis, it will be necessary to develop and implement standardized and accurate pattern recognition technology capable of differentiating exercise modalities to support the evaluation of thermographic data by means of radiomics.

运动生理学中的红外热成像：运动放射学的曙光。

红外热成像（IRT）是一种用于测量人体表面辐射温度（Tsr）的非侵入性工具。由于相机镜头，检测器技术和数据处理能力的最新发展，IRT是一项即将到来的技术。这篇综述的目的是在运动生理学中动态测量的背景下确定IRT的潜力和适用性。我们搜索PubMed和Google Scholar以找出合适的文章，并使用高分辨率IRT相机（640×480像素）进行了六个案例实验，以进行补充说明。确定了10篇关于耐力运动的文章，12篇关于增量运动测试的文章和11篇关于阻力运动的文章。检测到不同运动类型的特定Tsr变化。接近体力活动或长时间运动时，最近有六项研究描述了“树形”或“超​​热”表面辐射方向图（Psr），而没有进一步的说明。首次，我们描述了Tsr和Psr动力学以及它们在运动过程中如何与生理适应有关，并说明了Psr对​​抵抗力或耐力运动的不同反应性。我们讨论了如何通过创新的技术方法解决与个体因素（如皮肤血流量）或环境因素有关的偏见。我们具体说明了为什么IRT似乎越来越有能力区分与运动生理学家相关的生理特征与各种形式的环境，技术和个人偏见。为了进行精细分析，
