Due to the possible impact of the thermoregulatory process on sports performance, it is necessary to explore the existing relationships between kinetic, mechanical, and physiological variables. The objective of this study was to evaluate metabolic stress using thermography in the lower limb after the Spanish Championship 2023 walk. A descriptive study was carried out on national and international race walkers before and after the 2023 Spanish Championships. The participants performed different tests within the same circuit. Five walkers completed the long-distance race of 35 km, four walkers completed the middle-distance race of 20 km and finally, two walkers completed the short-distance race of 10 km. Statistically significant changes were observed in the lower limbs of the walkers after completing the test. We observed a decrease in skin temperature in all the anatomical regions analyzed, except for the back of the leg. More specifically, the decrease was in the hip (-1.92 °C: = 0.004), quadriceps, hamstrings (-1.23 °C: = 0.002), and tibia (-1.23 °C: = 0.030). However, in the posterior region of the leg, a significant increase in temperature was observed (+0.50 °C: = 0.011) following the competition. The findings in this descriptive investigation support the notion that thermography may serve as a useful tool in the acute analysis of muscle functional activation and metabolic response in professional marching athletes. Moreover, the results confirmed that the change in skin temperature is the result of a variation in acute metabolic and functional activation in the lower extremities of race walkers during competition, with infrared thermography representing an instrument capable of detecting such a change in a rapid and non-invasive manner.
由于体温调节过程可能对运动表现产生影响，因此有必要探讨运动学、力学和生理学变量之间的现有关系。本研究的目的是使用热成像技术评估 2023 年西班牙锦标赛后下肢的代谢应激。
在 2023 年西班牙锦标赛之前和之后，对国内和国际竞走运动员进行了描述性研究。参与者在同一赛道上进行了不同的测试。五名运动员完成了 35 公里的长距离比赛，四名运动员完成了 20 公里的中距离比赛，最后两名运动员完成了 10 公里的短距离比赛。
在完成测试后，观察到运动员下肢的统计数据发生了显著变化。我们观察到所有分析的解剖区域的皮肤温度都降低了，除了小腿后面。更具体地说，臀部 (-1.92°C: = 0.004)、股四头肌、腘绳肌 (-1.23°C: = 0.002) 和胫骨 (-1.23°C: = 0.030) 的温度均降低。然而，在腿部的后区域，比赛后观察到温度显著升高 (+0.50°C: = 0.011)。
本描述性研究的结果支持这样一种观点，即热成像可能是一种有用的工具，可以对专业行军运动员肌肉功能激活和代谢反应的急性分析提供帮助。此外，结果证实，皮肤温度的变化是竞赛中赛跑运动员下肢急性代谢和功能激活变化的结果，而红外热成像技术代表了一种能够快速、非侵入性地检测这种变化的仪器。
