    Abstract Abstract Skeletal muscle tissue has the largest mass in the human body, accounting for 45% of the total weight. Muscle injuries can be caused by bruising, stretching or laceration. The current classification divides these injuries into mild, moderate and severe. The signs and symptoms of grade I lesions are edema and discomfort; grade II, loss of function, gaps and possible ecchymosis; and grade III, complete rupture, severe pain and extensive hematoma. The diagnosis can be confirmed by ultrasound, which is dynamic and cheap, but examiner dependent; and magnetic resonance imaging (MRI), which provides better anatomical definition. The initial phase of the treatment consists in protection, rest, optimal use of the affected limb, and cryotherapy. Nonsteroidal anti-inflammatory drugs (NSAIDs), ultrasound therapy, strengthening and stretching after the initial phase and range of motion without pain are used in the clinical treatment. On the other hand, surgery has precise indications: hematoma drainage and muscle-tendon reinsertion and reinforcement.

    Abstract The study of the human body's energy behavior has received more attention over the past years. The development of thermal infrared cameras brought new possibilities for evaluating physical exercise performance. This work aims to study the skin temperature distribution during treadmill running and cycle ergometer tests with a graded load exercise until exhaustion. Eight amateur athletes performed both tests. In addition, the ventilatory and metabolic data were measured by indirect calorimetry. The thermoregulatory system is highly requested to maintain the internal body temperature. Consequently, the average skin temperature decreased during running and cycling tests, although with a higher variation in running. It was observed that the lower limbs had a similar performance for both exercises; on the other hand, the upper limbs had a higher temperature decrease for running. This may be explained by increased body energy transfer to the environment due to higher degrees of freedom during the test. The main contribution is comparing the thermal behavior of the person's skin performing two different activities, constructing a basis for future energy and exergy analysis of the human body under physical activities complementary to the literature.

    Abstract ABSTRACT Objective: To evaluate the nature and rate of sports injuries in medical students, as well as the risk factors at these events. Methods: All student-athletes (218) from a Medical School, integrated in at least one of the six team sport modalities (soccer, rugby, indoor soccer, handball, basketball, and volleyball) in 2017, were included. Injuries affecting their performance, regardless of time loss, were included. Athlete-exposure (A-E) was defined as one student-athlete participating in one practice or game. Results: Injury rates were significantly higher in junior medical students (1st - 3rd year) (7.58 per 1000 A-E, 95%CI = 6.11-9.06) than in senior medical students (4th - 6th year) (4.49 per 1000 A-E, 95%CI = 3.26-5.73) (p < 0.001). Multi-sports athletes had higher injury rates (10.69 per 1000 A-E, 95%CI = 8.22-13.17) than single-sport athletes (4.49 per 1000 A-E, 95%CI = 3.51-5.47) (p = 0.002). More than 60% of reported injuries occurred in the lower limbs and the mechanism that accounted for most injuries in games was player contact (51%); whereas in practice, it was non-contact (53%). Conclusion: Junior medical students present a higher injury rate than seniors. Medical students practicing more than one modality had a higher injury rate than those involved in just one sport modality. Level of Evidence IV, Cross-Sectional Study.

    Abstract Esta nova série de artigos tem por objetivo levar aos leitores nacionais e internacionais algumas das mais importantes contribuições provenientes da literatura médica brasileira recente. Embora possa parecer que não tenham relação direta com a Medicina do Exercício e do Esporte, são trabalhos que podem oferecer suporte a muitas linhas de pesquisa nessa área. Os artigos originais mais relevantes são selecionados por experientes editores, a quem solicitamos que escolham palavras- chave para que sejam destacadas para chamar a atenção do leitor. Para facilitar a leitura, os artigos são organizados por área de interesse. Para aproveitar ao máximo o limitado espaço editorial, não são incluídos os nomes dos autores dos artigos. Entretanto, a referência completa é oferecida ao final do artigo. O resultado final traz o que há de melhor do artigo, seguido de uma sintética interpretação pessoal. Endereçado ao médico ocupado, esperamos que esta inciativa possa contribuir para o sucesso da translação do conhecimento da evidência científica para a prática clínica. This brand-new series of articles aims at delivering to national and international readers some of the cutting-edge contributions from the Brazilian medical literature. Some of them may not be directly related to the area, but they can be the grounding for scientific research in the field of Sports and Exercise Medicine. Recently, papers published in the main Brazilian medical journals are carefully selected and analyzed by skilled medical editors. In addition, we asked editors to choose keywords to be highlighted in order to call the reader's attention. Articles are organized by area of interest to facilitate reading. To get the most of the limited available editorial space we did not include the names of the authors of the related articles in the text itself, but a complete reference guide is provided at the end of the article. The result carries the best from the original paper accompanied by a personal interpretation. Directed to the busy medical doctor, we hope that this initiative may contribute to the successful translation of knowledge from scientific evidence to clinical practice.

    Abstract ObjectiveTo evaluate thermography application as a complementary method in preventing muscle injury in professional soccer players. MethodsA longitudinal prospective study with 28 professional soccer players that composed a first division of Brazilian’s soccer team between 2015 and 2016. In both seasons (2015 and 2016), muscle injuries were documented and classified in grade of severity, by ultrasound. During the following season (2016), infrared medical thermography was applied twice a week (48 hours after game) and if a difference of temperature was detected higher than 0.4°C, a prevention protocol was initiated. Muscle injuries in 2016 were documented.ResultsIn 2015, the total number of muscle injuries was 11. In 2016, the total number of muscle injuries was 4 (p=0.04). It represents an incidence/player of 78% in 2015 and 28% in 2016, corresponding to a decrease of 64% in 2016. Seven players played in the first team in both seasons. Among these seven players, muscle injuries were reduced from 8 (in 2015) to 3 (in 2016)—a decrease of 63% in the season we used thermographic monitoring (p=0.06).ConclusionThe pilot data provide a promising catalyst for a rigorous RCT that could examine whether thermography can contribute to a muscle injury prevention programme.

    Abstract ABSTRACT Objective: To obtain information on the incidence and nature of sports injuries at a Brazilian university. Method: Data from 396 student amateur athletes (61% male) playing 15 different sports during the 2013 season were retrospectively evaluated. Subjects completed the National Collegiate Athletic Association Injury Surveillance System questionnaire at the conclusion of the 2013 sports season. Injuries that resulted in at least one day of time lost were included. Exposure was defined as one student amateur athlete participating in one practice or game and is expressed as an athlete-exposure (A-E). Results: Injury rates were significantly greater in games (13.13 injuries per 1000 A-Es, 95% CI = 10.3-15) than in practices (4.47 injuries per 1000 A-Es, 95% CI = 3.9-5.1). The mechanisms that accounted for the most injuries in games and practices were player contact (52.9%) and non-contact (54.5%), respectively. Ankle ligament sprains were the most common injury (18.2% of all reported injuries). A relatively high incidence of anterior cruciate ligament injury was also observed (0.16 injuries per 1000 A-Es). Conclusion: Brazilian student amateur athletes are at great risk of sustaining non-contact injuries such as ankle sprains and anterior cruciate ligament injuries. Level III of Evidence, Study of non consecutive patients; without consistently applied reference ''gold'' standard.

    Abstract ABSTRACT Objective: To compare the transparent 3D computed tomography (CT) image protocol against conventional 3D-CT image-rendering protocol to assess femoral tunnel position in anatomic anterior cruciate ligament (ACL) reconstructions . Methods: Eight knee CT scans from cadavers were analyzed by image rendering 3D-CT protocol, using Rhinoceros(r) software. The central point of the ACL tunnel was set using the sagittal plane. Same CT scans were analyzed using transparent 3D-CT measurement protocol with OsiriX(r) software. Central point of the ACL tunnel was set using sagittal, coronal and axial planes. The grid system described by Bernard and Hertel was used to compare tunnel positions between protocols, using height and length parameters . Results: There was a significant difference between measurements using image rendering 3D-CT and transparent 3D-CT protocol for height (23.8 ± 7.9mm and 33.0 ± 5.0mm, respectively; p=0.017) and no differences for length (18.6 ± 4.2mm and 18.3 ± 4.5mm, respectively; p=0.560) . Conclusion: Height in transparent CT protocol was different and length was the same as compared to 3D-CT rendering protocol in Bernard and Hertel method for tunnel measurements.
