Anthropometry has been widely used in different fields, providing relevant information for medicine, ergonomics and biometric applications. However, the existent solutions present marked disadvantages, reducing the employment of this type of evaluation. Studies have been conducted in order to easily determine anthropometric measures considering data provided by low-cost sensors, such as the Microsoft Kinect. In this work, a methodology is proposed and implemented for estimating anthropometric measures considering the information acquired with this sensor. The measures obtained with this method were compared with the ones from a validation system, Qualisys. Comparing the relative errors determined with state-of-art references, for some of the estimated measures, lower errors were verified and a more complete characterization of the whole body structure was achieved.

In order to verify whether there is a considerable increase in body skin temperature during different swimming techniques (crawl and backstroke) and identifying the most affected regions. The athlete's thermal symmetry was also analyzed, as well as its modification after the swimming, according to the performed technique. The accuracy of thermography as a method to identify and distinguish these different styles was also evaluated. Ten male swimmers were recruited and two different swimming techniques were assessed, crawl and backstroke. After a 10 minute acclimatization period in the pool, the swimmers were quickly dried with microfiber towels. The thermograms were taken before and after the swimming task, which consisted in a 7x200m protocol in crawl or backstroke. Infrared thermography revealed an increase of temperature after exercise and no significant differences were found between both techniques. Thermal symmetry was not affected by exercise.

Actually , injuries are identified as persistent and serious problems in the sports activity. Ankle sprains compose a significant part of these injuries and present high frequency, which increases the associated costs. Among other issues, this condition is related to the common persistence of sequel and reoccurrences. The disregard for its severity and a reduced follow-up of the treatment may be pointed as associated causes. In this work, two Rugby athletes that were recovering from ankle sprains and receiving physiotherapeutic treatment were monitored. Infrared thermography, a non-contact, noninvasive, non-ionizing, precise and fast medical imaging modality, has been used for analyzing the skin surface temperature distribution of the affected area. The analysis of the collected thermograms has shown a positive evolution of treatment to the ankle sprain in both cases examined. From the statistical analysis of the data, it was possible to differentiate the two cases presented, evidencing different recoveries. In conclusion, by applying the developed and proposed methodology in these the two cases, it has been possible to confirm that infrared thermography may assume a relevant role in monitoring ankle sprains.
