La termografía infrarroja como herramienta efectiva para detectar áreas músculares dañadas después de correr una maratónIntroducción. La termografía infrarroja (TI) es un equipo de imagen que capta las radiaciones de calor emitidas por los cuerpos y las recoge en valores de temperatura. En el ámbito deportivo se utiliza para identificar daños en estructuras músculo-esqueléticas a partir de la variación de la temperatura corporal en zonas anatómicas afectadas.Objetivo. Valorar la efectividad de la TI como herramienta para detectar músculos dañados después de correr una maratón.Materiales y métodos. Se evaluaron 17 corredores antes y después de correr una maratón (42.196 km) utilizando un equipo termográfíco.Resultados. Se encontraron diferencias estadísticamente significativas entre la temperatura previa y posterior a correr una maratón. Se presentó una diferencia entre la medición previa y posterior >1°C en el vasto lateral, vasto medial, recto femoral y aductor de la pierna dominante, lo que, basados en parámetros clínicos, representa un daño en estos músculos. Los aumentos de temperatura se mostraron de manera heterogénea entre las zonas anatómicas.Conclusiones. La TI es una herramienta efectiva para detectar zonas musculares dañadas en corredores después de participar en una maratón.Palabras clave: Termografía; Músculos; Carrera; Lesiones (DeCS). | Abstract |Introduction: Infrared thermography (IT) is an imaging technique that detects heat radiation emitted by an object and collects it to convert it into temperature values. In sports, it is used to identify damage to musculoskeletal structures based on the variation of body temperature in affected anatomical areas.Objective: To assess the effectiveness of IT as a tool to detect damaged muscles after running a marathon. Materials and methods:17 runners were assessed before and after running a marathon (42.196 km) using thermographic equipment.Results: Statistically significant temperature differences were found before and after running a marathon. There was a difference between previous and posterior measurement >1°C in the vastus lateralis, vastus medialis, rectus femoris and adductor of the dominant leg, which, based on clinical parameters, indicates damage in these muscles. Increases in temperature were heterogeneous among anatomical areas. Conclusions:IT is an effective tool for detecting damaged muscle areas in runners after participating in a marathon.Keywords: Thermography; Muscles, Running, Injuries (MeSH).

Heat Strain, External Workload, and Chronic Kidney Disease in Tropical Settings: Are Endurance Athletes Exposed?

“…Athletes experiencing AKI according to these definitions have been documented to regain baseline renal function in a matter of 1–15 days (Kim et al, 2015; Abbas et al, 2019; Rojas-Valverde et al, 2019), however, documentation also exists of more serious consequences, leading to the death of the athlete in combination to other potential risks (Asserraji et al, 2014). Due to the lack of information about whether the repeated AKI can lead to future CKD (Hoffman and Weiss, 2016), there is a need for studies that shed light on the potential of the combination of environment and physical thermal load in athletes to trigger future CKD, especially in tropical settings, where conditions of high thermal stress exist almost year-round in some regions (Gutiérrez-Vargas et al, 2017, 2018). Unfortunately, in order to observe whether AKI caused by heat exposure and prolonged physical exercise provokes CKD on the long-term requires cohort studies in a long timeframe; such a timeframe could be too late for affected athletes (Eichner, 2017).…”

“…Finally, it should be considered that the dorsal muscle is interrupted in the thermographic analysis since two images were not processed correctly. It would be expected, however, that since there is a greater hyperthermic tendency in the upper extremities, being more relevant in the shoulder and biceps, and taking into account the motor link between the biceps and the dorsal muscle, said dorsal muscle would have had a similarly greater hyperthermic tendency in DEC (Gutiérrez-Vargas et al, 2017). In contrast, not only the lats but also all the upper body muscles measured in the thermography show a gradual deactivation in the BED that is very clearly observable in Figure 16.…”

Short-Term Skin Temperature Responses to Endurance Exercise: A Systematic Review of Methods and Future Challenges in the Use of Infrared Thermography

“…Considering multiple thermographic brands and settings selected to obtain the thermograms, studies should be performed on how different settings, such as room temperature and relative humidity, the camera distance from the skin, thermal adaptation time, and participants' positions, could potentially influence temperature data. How do the stimuli influence temperature changes depending on the exercise settings (e.g., exercising in hot, humid, windy environments) [31,58]? Additionally, considering the studies extracted, the selection of several ROIs sometimes did not consider the segmentation of an area (e.g., quadriceps into rectus femoris, vastus lateralis, and medialis); it should be analysed whether the sub-areas of a body segment could present differences in temperature due to the different ROIs selected [35].…”

“…Moreover, despite the vast amount of evidence regarding the Tsk responses in acute conditions to relatively short stimuli, such as time to exhaustion tests, incremental tests, and other similar tests lasting 15-60 min at different intensities, there is a lack of studies recording the physiological skin responses to heavier and longer stimuli, such as the marathon, long-distance triathlons, multi-stage cycling, open-water swimming, and other similar efforts, that could allow a more in-depth analysis of the behaviour of Tsk and its relationship with other well-known physiological responses, such as muscle damage, pain, and temperature regulation [31,58].…”
