RESUMO

BACKGROUND: In combat sports, successful competition and training require comprehensive motor fitness. The aim of this study was to diagnose the level of physical fitness and to determine the level of differences between athletes of combat sports characterized by stand-up fighting, such as Muay Thai; and ground fighting, such as Brazilian jiu-jitsu. METHODS: The study examined and compared 30 participants divided into two equal groups: Muay Thai athletes (n = 15; age: 24.24 ± 3.24; body height: 174.91 ± 5.19; body weight: 77.56 ± 7.3), and Brazilian jiu-jitsu (BJJ) (n = 15; age: 22.82 ± 1.81; body height: 175.72 ± 7.03; body weight: 77.11 ± 8.12). Basic characteristics of the somatic build were measured. Selected manifestations of the motor potential of motor skills were also evaluated using selected tests from the EUROFIT test battery, the International Test of Physical Fitness, and computer tests of coordination skills. Relative strength and maximal anaerobic work (MAW) indices were calculated. The strength of the relationship between the effect of motor fitness and training experience was also assessed. RESULTS: The athletes of both groups (Muay Thai and BJJ) presented similar levels of basic characteristics of the somatic build. Motor fitness in the tested groups showed significant differences between the athletes of these sports in static strength (p = 0.010), relative strength (p = 0.006), arm muscle strength in pull-ups (p = 0.035), and functional strength in bent arm hanging (p = 0.023). Higher levels of these components of motor fitness were found for the athletes in the BJJ athletes. In the Muay Thai group, significant very high strength of association was found between training experience and five strength tests. Furthermore, a significantly high strength of association was found in two tests. In the BJJ group, significant relationships with very high correlation were found between the variables in five strength tests. CONCLUSIONS: Brazilian jiu-jitsu athletes performed better in strength tests (static strength, relative strength, shoulder girdle strength, functional strength). High correlations between the training load and the level of physical fitness were found in flexibility and strength tests in BJJ athletes and most strength tests in Muay Thai athletes.

RESUMO

The study aimed to explore the sensitivity and specificity of a new methodological approach related to the musical rhythm for discriminating a competitive Cuban dancer's (CDCs) level. Thirty CDCs (Age 23.87 ± 1.76 years, body mass 60.33 ± 9.45 kg, stature 1.68 ± 0.07 m) were divided into three groups: beginner (BEG, n = 10), intermediate (INT, n = 10), and advanced (ADV, n = 10) according to their training experience/level. Each dancer was assessed while dancing at three different musical rhythms: fast (118 BPM), medium (96 BPM), and slow (82 BPM). The assessed variables were average heart rate (HRM), peak (HRP), and dancing time (DCT). The ADV group succeeded at all three musical combinations (317, 302, 309 s for 82, 96, 118 BPM). The INT group correctly performed only the first two combinations (304, 304 s for 82, 96 BPM), while a significant time difference was shown at the fast musical rhythm (198 ± 6.64 s) compared to the medium (p < 0.001) and slow rhythms (p < 0.001) respectively. As the speed of the musical rhythms increased, the BEG group was not able to follow the rhythm: their results were 300 ± 1.25 s for the slow musical rhythm, 94.90 ± 12.80 s for the medium musical rhythm and 34.10 ± 5.17 s for the fast musical rhythm (p < 0.001). The HRM and HRP grew along with the increase in musical rhythm for all groups (p < 0.001). The ROC analysis showed a high sensitivity and specificity in discriminating the groups for each rhythm's condition. The BEG and INT groups showed an AUC = 0.864 (95% CI = 0.864-0.954); INT and ADV showed an AUC = 0.864 (95% CI = 0.864-0.952); BEG and ADV showed an AUC = 0.998 (95% CI = 0.993-1.000). The results of this study provided evidence to support the construct and ecological validity of the time of the musical rhythms related to competitive CDCs. Furthermore, the differences in the performances according to various musical rhythms, fast (118 BPM), medium (96 BPM), and slow (82 BPM), succeeded in discriminating a dancer's level. Coaches and strength and conditioning professionals should include the Cuban Dance Field Test (CDFT) in their test battery when dealing with talent detection, selection, and development.

RESUMO

During running, the mechanical energy of the centre of mass of the body (COM) oscillates throughout the step like a spring-mass system, where part of its mechanical energy is stored during negative phases to be released during the following positive phases. This storage-release of energy improves muscle-tendon efficiency, which is related to lower-limb stiffness. This study explores the effect of sports background on the bouncing mechanism, by examining differences in stiffness and step spatiotemporal parameters between swimmers and football athletes. All athletes performed three consecutive running bouts on an instrumented treadmill at three different speeds (3.9, 4.4 and 5.0 m·s-1). The ground reaction forces were recorded. Vertical stiffness and step spatiotemporal parameters were analysed and compared using a two-way ANOVA. Vertical stiffness of football players was on average 21.0 ± 1.1% higher than swimmers. The modification of step spatiotemporal parameters also suggests a more elastic rebound by increasing the stretch of tendons relative to muscle within muscle-tendon units in football players. Compared to swimmers, they (1) decrease the effective contact time by 9.7 ± 2.4% and (2) decrease the duration of the push by 15.0 ± 6.4%, suggesting that background training adaptations influence spring-mass behaviour during running.

RESUMO

Propósito/Contexto. Este artículo tiene como propósito indagar sobre la enseñanza universitaria de la ética, en ciencias de la salud, a través de una serie televisiva. Las experiencias formativas en esta área suelen enfocarse en la práctica profesional futura a través de casos clínicos breves, dejando relegado el ámbito educativo. Metodología/Enfoque. La metodología utilizada es mixta. Se toma como antecedente la herramienta REST para la evaluación de la sensibilidad ética a partir de la detección de elementos dilemáticos en un audiovisual y se realiza una experiencia de innovación docente con un fragmento de la serie Merlí donde se relata un caso de deshonestidad académica. Los estudiantes debían delimitar las situaciones dilemáticas del fragmento y articularlas con el código de ética universitario. El estudio incluye elementos cuantitativos de la detección de situaciones y principios éticos, y elementos cualitativos de análisis de contenido. Resultados/Hallazgos. Los resultados son, por un lado, la identificación de todas las situaciones del fragmento, focalizándose en mayor medida en aquellas que tienen como protagonistas a los docentes y, además, en las que implican una transgresión explícita de las normas. Los estudiantes pueden identificar situaciones dilemáticas pero les resulta más complejo vincularlas a los principios éticos. Discusión/Conclusiones/Contribuciones. La contribución principal del artículo es la advertencia sobre la relevancia de la aplicación y la reflexión sobre la ética en el ámbito universitario, a la vez que se destaca la utilidad del cine y las series televisivas en experiencias de innovación pedagógica en ética y bioética.

Purpose/Context. The purpose of this article is to investigate the university teaching of ethics in health sciences through a TV series. Training experiences in this area usually focus on future professional practice through brief clinical cases, leaving the educational field relegated. Methodology/Approach. The methodology used is mixed. The REST tool for the evaluation of ethical sensitivity is taken as an antecedent from the detection of dilemmatic elements in an audiovisual and an experience of teaching innovation is carried out with a fragment of the TV series Merlí where a case of academic dishonesty is reported. The students had to define the dilemmatic situations of the fragment and articulate them with the university code of ethics. The study includes quantitative elements of detection of situations and ethical principles, and qualitative elements of content analysis. Results/Findings. The results are, on the one hand, the identification of all the situations of the fragment, focusing more on the fact that they have teachers as protagonists, and also, those that imply an explicit transgression of the norms. Students can identify dilemmatic situations but find it more complex to link them to ethical principles. Discussion/Conclusions/Contributions. The main contribution of the article is to note the relevance of the application and the reflection on ethics in the uni-versity environment, while highlighting the usefulness of cinema and television series in experiences of pedagogical innovation in ethics and bioethics.
