“…The transformation model and the mapping model could be defined depending on the specific application. For IRT applications in sports and exercise science, a procedure to obtain a reliable morphing of the whole body onto a template was presented by Fournet et al (2012Fournet et al ( , 2013Fournet et al ( , 2017. The proposed image processing method combined a segmentation procedure with 51 ROIs and a morphing algorithm necessary to average several thermograms.…”

Objective: Infrared thermography (IRT) is a non-invasive, contactless and low-cost technology that allows recording of the radiating energy that is released from a body, providing an estimate of its superficial temperature. Thanks to the improvement of infrared thermal detectors, this technique is widely used in the biomedical field to monitor the skin temperature for different purposes (e.g. assessing circulatory diseases, psychophysiological state, affective computing). Particularly, in sports and exercise science, thermography is extensively used to assess sports performance, to investigate superficial vascular changes induced by physical exercise, and to monitor injuries. However, the methods of analysis employed to treat IRT data are not standardized, and hence introduce variability in the results. Approach: This review focuses on the methods of analysis currently used for thermal imaging in sports and exercise science. Main Results: Firstly, the procedures employed for the selection of regions of interest (ROIs) from anatomical body districts are reviewed, paying attention also to the potentialities of morphing algorithms to increase the reproducibility of thermal results. Secondly, the statistical approaches utilized to characterize the temperature frequency and spatial distributions within ROIs are investigated, showing their strengths and weaknesses. Moreover, the importance of employing tracking methods to analyze the temporal thermal oscillations within ROIs is discussed. Thirdly, the capability of employing procedures of investigation based on machine learning frameworks on thermal imaging in sports science is examined. Significance: Finally, some proposals to improve the standardization and the reproducibility of IRT data analysis are provided, in order to facilitate the development of a common database of thermal images and to improve the effectiveness of IRT in sports science.

“…To the authors' knowledge, there is no evidence of evaluating thermal comfort on mountain bikers using backpacks through IT. Hiking studies have assessed the effect of garments in thermoregulation mainly (Fournet & Havenith, 2017). Nonetheless, conditions such as wind speed, movement speed, and anatomic postures acquired on mountain biking differ from hiking, leading to different thermoregulation results.…”

Using infrared thermography, we assess how a new backpack design for mountain bikers can contribute to their thermoregulation process and perceived comfort during a cycling activity in a controlled environment. We gathered qualitative and quantitative data of heat concentration areas on skin temperature and thermal comfort perception by comparing two types of backpacks: a conventional backpack and a novel backpack design. Our results show that a guaranteeing airflow due to distance between the user’s back and the backpack with a rigid backplate and an arc radius morphology improves heat dissipation and thermal comfort for mountain bikers.

“…[19]. Other studies were focused on the prevention of injuries during exercise [20], on the relationship between animals' thermal profile and their performance [21] or on the evaluation of sportive clothing during exercise [22,23]. Finally, methodologies for the use of IRT applied to different sports, in terms of the definition of the regions of interest (ROIs), assessment protocol and data analysis [24] were studied.…”

Effect of Exercise on Athletes Performing in Fencing Uniforms: Methodology and Preliminary Results of the Use of Infrared Thermography to Detect the Thermal Behaviour of Fencers

et al. 2020

In recent times, infrared thermography has been often applied to sport science, in order to evaluate athletes’ performance in relation to their thermal behaviour. As there is a lack of studies for the sport of fencing, this paper aims to provide preliminary results showing the thermal behaviour of fencers of different competitive level and to provide a methodology for its assessment. In particular, thermal images were acquired before, during and after the training, as well as the metabolic rate and the rate of perceived exertion, for eight fencers with different competitive levels (international/national/veteran). Results showed that in moderate environments there was any correlation between the environmental parameters and temperature trend on athletes’ bodies, while competitive level and thermal behaviour were connected. The presence of thermal asymmetries was also detected. In general, from these preliminary results, professional athletes presented the same temperature trend. Therefore, further studies should be carried out in order to investigate these findings on a larger sample of elite athletes, as their thermal response may be important for improving their performance.
