Análise comparativa da termografia com a escala PSE/BORG aguda em um clube de futebol

Abstract

The use of the Borg CR10 scale adapted in sports is an important tool in the evaluation of effort intensity and optimization of training, preventing sports injuries. Thermography is a non-invasive and low-cost imaging test that requires little time for its use, being an adjuvant method in the evaluation of acute metabolic responses through heat variation. To evaluate the thermography and its alterations comparing with the subjective effort scale PSE/BORG in athletes of the basic categories of soccer in a club in the city of Belém - PA. 70 thermographic images and 73 modified PSE/BORG scores were captured, between 8 games of the Paraense Under-20 Championship and the Brazilian Under-23 Aspirants Championship, including 22 athletes registered in the BID (CBF Newsletter). For analysis of thermographic images, the present work used the FLIR TOOOLS software. Athletes were submitted to thermography capture and PSE/BORG scale after the end of the matches. Data organization was performed using Microsoft Word, Excel, Bioestat 5.5 and GraphPad Prism 8.4..2. For analysis of the data obtained, the Kruskal-Wallis tests were performed, adopting a (p < 0.05) being statistically significant. All practitioners signed the Free and Informed Consent Term. The number of thermographic images captured varied between 6-12 between collection days. The highest median of variation occurred on the eighth day (0.4C°) with a p=0.265 in the anterior thigh muscles. The highest median thermal variation of the anterior leg muscles occurred on the fifth and seventh days, respectively (0.4C°) with p=0.848. During the analysis, 73 PSE/BORG scores were performed, the seventh and eighth days with values greater than or equal to 7. The comparative analysis found a negative correlation between the temperature of the anterior thigh muscles and the PSE/BORG scale (p=0.206) without differ significantly from a value of zero. The correlation between anterior leg muscles temperature and PSE/BORG scores was positive (p=0.412) without significantly differing from a zero correlation. The use of thermography and the PSE/BORG scale are relevant in clinical practice for better health and better use of athletes. The present study demonstrated that there was no correlation between thermography and its numerical variations with the anterior thigh muscle segments using the PSE/BORG scale. However, there was a positive correlation between the anterior leg muscles and the scores. Therefore, it is important to emphasize the need for an analysis for a longer period in relation to this work. proved to be effective in preventing injuries in the evaluated athletes.
