Pode a termografia auxiliar no diagnóstico de lesões musculares em atletas de futebol?

Abstract

Introduction: Since muscle injuries trigger inflammatory processes and inflammation generates heat due to increased local metabolism, hence the level of inflammation can be measured by the temperature gradient. Objective: To assess the feasibility of application of thermography in the diagnosis of injuries caused by physical training. Methods: The study was conducted with adolescent athletes of the Paraná Club, Curitiba, Brazil, who were divided into two groups, namely control and experimental. The control group attended a training session of low intensity and the experimental group a high intensity one. First, a thermographic image of the quadriceps of each athlete was acquired before the training session. After the training session, a blood sample was collected to check the level of serum lactate of each athlete. Subsequently, 24 hours after training, an extra blood sample was performed to check the level of serum CK of each athlete. Another individual thermographic image of the quadriceps was acquired at that stage. Results: The correlation between the lactate and CK was positive and statistically significant rho value = 0.661 (p = 0.038). There was no statistically significant correlation between CK values 24 h post-training and the change in temperature (24 h post-training -pre-training) in the muscles evaluated for the control group. There was a statistically significant difference in temperature (24 h post-training -pre-training) (p<0.05) for the three muscles studied only in the experimental group. Conclusion: The results of this study suggest the possibility of use of thermographic images, together with creatine kinase, in order to determine the intensity and location of post-training muscle damage, since the previously mentioned biochemical marker cannot determine the anatomic location of the muscle injury.

The influence of subcutaneous fat in the skin temperature variation rate during exercise

“…Thermal imaging have been used for diagnosis of sports injuries (Bandeira et al, 2014) and injuries after strength training (Bandeira et al, 2012). Recently, researchers have investigated the thermal response during and after exercise (Chudecka and Lubkowska, 2012;Merla et al, 2010).…”

“…Recently, researchers have investigated the thermal response during and after exercise (Chudecka and Lubkowska, 2012;Merla et al, 2010). However, this response depends on some variables such as: fitness level (Formenti et al, 2013), muscle mass in the region of interest (Neves et al, 2015a), subcutaneous fat (Bandeira et al, 2012), type and intensity of exercise (Neves et al, 2015b;2015c).…”

“…Although some authors (Bandeira et al, 2012;Formenti et al, 2013) have reported that subcutaneous fat layer has some influence on the skin temperature, were not presented quantitative data regarding this influence. One variable investigated to understand the local thermal response during exercise is the skin temperature variation rate.…”

“…Several studies report the influence of subcutaneous fat layer on the skin temperature and its influence on the dissipation of body heat (Bandeira et al, 2012;Chudecka and Lubkowska, 2012;Savastano et al, 2009); however they did not perform group stratification by subcutaneous fat layer of the active muscle region. And yet, the body thermal response varies according to each body region, each muscle group Volume 31, Number 4, p. 307-312, 2015 and according to the type and intensity of exercise (Neves et al, 2015d).…”

Acute effect of a fight of Mixed Martial Arts (MMA) on the serum concentrations of testosterone, cortisol, creatine kinase, lactate, and glucose

“…Similarly, CK serum values may increase after a fight, reflecting the levels of muscle damage (Baird, Graham, Baker, & Bickerstaff, 2012;Bandeira, Moura, Souza, Nohama, & Neves, 2012;Coswig et al, 2013). This enzyme is found mostly in muscles and, on the occasion of fiber rupture due to muscle strain, is released into the blood flow.…”
