A aplicação da termografia infravermelha, pós-jogo, para detecção de sinais cardinais inflamatórios primários, em isquiotibiais, de jogadores de futebol profissional

Abstract

Soccer is one of the most practiced sports worldwide, and admits intermittent physical characteristics. The major incidence of injuries occurs in the posteral muscle thigh, in hamstrings. This type of injury promotes a great time of non-activities, and it's more propensive to recidives. For these reasons, the most of teams were worried about it. This study mainly aimed to verify what part of the hamstring muscle (proximal or distal) showed great inflammatory signs throughout five consecutive games. Furthermore, determine which moment presents the highest peak about the first game. Ten professionais players were analyzed. The ages average was 27,5 years ± 4,2, height 180 ± 4,5 cm, body mass 80,5 ± 5,7 kg, fat mass 7,8 ± 1,1 and lean mass 51,6 ± 1,4. The protocol occurred in three different moments: the first day was used to characterize the sample. After this, the players participated in at least 75% of the full game. And the final moment was taking the infrared picture between 24-48 hours after the match. The pictures were taken by Flir T-420 camera and analyzed for a specific software (APOLLO®, version 1.0, BR). Data were calculated by the delta between the number of pixels/ºC of the proximal region and distal. The normality test was Shapiro-Wilk. ANOVA one way was used for analyses the data, and the effect size was used ETA², classified as small (0,01<ɳ2 ≤ 0,06), medium (0,06 < ɳ2 ≤ 0,14) e big (ɳ2 > 0,14). The results showed a great number of pixels/ºC at the proximal region, and the highest peak in the fifth match when compared with the first game (p=0,025). Conclusion: the findings agreed with other researchers, which proved that the major incidence of soccer player injuries is in the bíceps femoral muscles, at the proximal long head. Moreover, it could help to improve the prevention strategies of recovery.
