Abstract

Introduction: 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. Method: 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. Result: 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: p = 0.004), quadriceps, hamstrings (-1.23 °C: p = 0.002), and tibia (-1.23 °C: p = 0.030). However, in the posterior region of the leg, a significant increase in temperature was observed (+0.50 °C: p = 0.011) following the competition. Discussion and Conclusions: 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.

分析竞走比赛中急性代谢应激反应的红外热成像传感器
导言:由于体温调节过程可能对运动成绩产生影响,因此有必要探索运动、机械和生理变量之间的现有关系。本研究的目的是利用热成像技术评估 2023 年西班牙竞走锦标赛后下肢的代谢压力。研究方法在 2023 年西班牙锦标赛前后,对国内和国际竞走运动员进行了描述性研究。参赛者在同一赛道上进行了不同的测试。五名竞走者完成了 35 公里的长距离比赛,四名竞走者完成了 20 公里的中距离比赛,最后两名竞走者完成了 10 公里的短距离比赛。结果完成测试后,步行者的下肢出现了明显的统计学变化。我们观察到,除腿部后侧外,所有分析区域的皮肤温度都有所下降。更具体地说,下降的部位是臀部(-1.92 °C:p = 0.004)、股四头肌、腘绳肌(-1.23 °C:p = 0.002)和胫骨(-1.23 °C:p = 0.030)。然而,在腿部后侧区域,观察到比赛后温度显著升高(+0.50 °C:p = 0.011)。讨论和结论:这项描述性调查的结果支持这样一种观点,即热成像技术可作为一种有用的工具,用于对专业行进运动员的肌肉功能激活和新陈代谢反应进行急性分析。此外,研究结果证实,皮肤温度的变化是竞走运动员在比赛期间下肢急性代谢和功能激活变化的结果,而红外热成像技术是一种能够以快速和非侵入性方式检测这种变化的仪器。

期刊介绍: Biosensors (ISSN 2079-6374) provides an advanced forum for studies related to the science and technology of biosensors and biosensing. It publishes original research papers, comprehensive reviews and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
