“…This information is of extreme importance in the planning of the training session that will follow the test application, since it offers the possibility to identify which regions had a higher demand and to plan the session avoiding excessive overload of those regions. In soccer, specifically, studies have sought to verify thermal asymmetries in order to identify and prevent injuries 25 . Regarding the results of thermal asymmetry, it was possible to note that there was no asymmetry in any of the regions analyzed, i.e., there was no contralateral difference greater than 0.3ºC, both before and after the test, indicating that there was no additional overload in none of the body hemispheres, since the differences found (0.1ºC to 0.3ºC) agree with the literature, which classifies asymmetry values <0.5ºC as normal 26 .…”

Introduction Infrared thermography has been used in several areas, mainly in sports training, and specifically in soccer. Objectives The objectives of the study were to verify the acute effect of a displacement speed test on the skin temperature of elite female soccer players, to observe pre- and post-test thermal asymmetries, and to compare responses in the anterior and posterior regions of lower limbs. Methods Cross-sectional study that evaluated 17 soccer players of the 2018 Brazilian Championship. They were submitted to thermography before and 10 minutes after performing the displacement speed test. Thermographic images were collected using a FLIR® model 8 thermal imager and changes in skin temperature in the anterior and posterior regions of the lower limbs were analyzed, according to the areas of interest. Descriptive statistics were performed and mean and standard deviation of the temperatures of the areas of interest were analyzed. The normality of the data was verified, and then the Student’s t test for normal paired and independent samples and the Mann-Whitney test for non-normal samples were conducted, with p <0.05 being adopted for significance level. Results It was possible to observe that after the test there was an increase in skin temperature in all the regions analyzed, both on the dominant and non-dominant sides (p <0.05). Regarding the analysis of the anterior region, it was possible to observe a higher temperature (p <0.05) in the region of the tibial muscles than in the region of the quadriceps muscles. Conclusion It is concluded that thermography helps to understand the thermal responses of lower limbs after applying the displacement speed test. The study shows that thermographic evaluation can guide the organization of the training session when motor tests have previously been applied, and in the detection of abnormal overloads, helping to prevent injuries.

“…These results are in agreement with other studies that observed the differences in the application of forces between lower limbs did not result in t skin asymmetries [ 40 , 41 ]. Hence, bilateral t skin asymmetries could be more related to the effect of an injury (e.g., inflammatory process or alteration of blood perfusion) [ 17 , 22 ] than with muscular strength imbalance.…”

“…However, this study pioneered the investigation of possible relationships among the parameters commonly used for the identification of injury risk factors for the thigh muscles (dynamometric parameters) of soccer players and t skin by IRT of hamstrings and quadriceps. Considering previous reports about the importance of a daily IRT asymmetry assessment in injury prevention [ 17 , 19 , 21 , 22 , 23 ], long-term follow-up studies of athletes using IRT evaluation are encouraged. Finally, based on a recent study [ 44 ], further investigations assessing the skin temperature recovery after a cold stress test could add valuable information to the vascularization status of the region analyzed by infrared thermography.…”

“…Studies have suggested that bilateral differences greater than 0.5 or 0.7 °C have been associated with physiological abnormalities [ 19 , 20 , 21 ]. In the sports scenario, IRT assessed at rest has been frequently used to pinpoint the injury location through skin temperature asymmetries [ 19 , 22 , 23 ], which could be mainly associated with inflammation or alteration of blood perfusion processes [ 17 , 24 ].…”

Although strength imbalances using isokinetic dynamometer have been examined for injury risk screening in soccer players, it is very expensive and time-consuming, making the evaluation of new methods appealing. The aim of the study was to analyze the agreement between muscular strength imbalances and skin temperature bilateral asymmetries as well as skin temperature differences in the hamstrings and quadriceps. The skin temperature of the anterior and posterior thigh of 59 healthy male soccer athletes was assessed at baseline using infrared thermography for the identification of hamstrings-quadriceps skin temperature differences and thermal asymmetries (>0.5 °C). Subsequently, concentric and eccentric peak torque of the quadriceps and hamstrings were considered in the determination of the ratios, as well as muscular asymmetries (>15%). When considering the torque parameters, 37.3% (n = 22) of the players would be classified as high risk for injuries. The percentage of those presenting skin temperature imbalances superior to 0.5 °C was 52.5% (n = 31). The skin temperature assessment showed sensitivity (22%) and specificity (32.2%) to identify torque asymmetries, demonstrating the inability to identify false negatives (15.3%) and false positives (30.5%) from all soccer athletes. In conclusion, skin temperature differences between hamstrings and quadriceps could be more related to thermoregulatory factors than strength imbalances.

“…Psychological pressure during sports competition disturbs the ideal physical movement and causes injury. Previous reports showed that the incidence of muscle strain in sports is higher during competition than during practice (Dalton et al 2015;Johnson and Comstock 2017;Eckard et al 2017aEckard et al , 2017bCôrte et al 2019). These reports may be attributable to the need for higher-intensity physical movements and stronger muscle contraction to achieve larger or faster movements for better results during competition (Dalton et al 2015;Eckard et al 2017a).…”

Psychological pressure during sports competition disturbs the ideal physical movement and causes injury. Baseball batting frequently causes trunk injuries. This study aimed to examine the influence of psychological pressure on the lumbar kinematics and trunk muscle activity during the baseball batting. Fourteen collegiate baseball players participated in this study. The participants performed bat swings under three different psychological conditions (non-pressure, pressure, and emphasized pressure). The lumbar kinematics and trunk muscle activity were measured during each bat swing. One-and two-way analyses of variance were performed to compare the lumbar kinematics and trunk muscle activity among different psychological pressure conditions. The lumbar flexion angle throughout the bat swing in the swing phase, from the moment of ground contact of the lead foot to the moment of ball contact, was significantly larger under the pressure and emphasized pressure conditions than under the non-pressure condition (P<0.05). The bilateral lumbar erector spinae (LES) activities in the swing and follow-through phases were significantly higher under the emphasized pressure condition than under the non-pressure condition (P<0.05). These results indicate that the baseball batting under psychological pressure influenced the lumbar kinematics and bilateral LES activities and may be related to the development of low back pain.
