MAIOR, Alex Souto; LEPORACE, Gustavo; TANNURE, Marcio  e  MAROCOLO, Moacir. Profile of infrared thermography in elite soccer players. Motriz: rev. educ. fis. [online]. 2017, vol.23, n.2, e101654.  Epub 22-Jun-2017. ISSN 1980-6574.  https://doi.org/10.1590/s1980-6574201700020013.

Aims

The aim of this study was to establish thermographic profiles of lower limbs and to correlate them with creatine kinase level in professional players.

Method

Thirty healthy male professional soccer players (25.4 ± 4.7 years; 179.5 ± 6.7 cm; 78.3kg ± 7.5 kg; body fat 10.2 ± 4.2 %) from a club of Brazilian first division soccer league volunteered. Thermal images sequences of lower limbs (thighs and legs) were acquired in an anteroposterior manner (i.e., frontal and dorsal views) by a digital infrared thermo-camera. Blood creatine kinase (CK) concentration was assessed by reflectance photometry. All thermographic images and CK were performed between 8:00 and 9:00 am.

Results

No significant difference (p>0.05) was found between left and right sides from both anterior and posterior measurements of thighs and legs for mean or maximal skin temperature. Low values of correlation (range r=0.14 to r=0.38) was found between skin temperature and CK levels while contralateral thermal symmetry in the lower limbs (regions of interest < 0.2°C) was found.

Conclusion

It was observed contralateral thermal symmetry in the lower limbs and low correlation between CK and temperature values in elite soccer players.
