(1) Objetive: Compare the internal load (ILO), external load (ELO) and wellness (WS) between official preparation friendly matches (FM) and France 2019 women world cup (WWC) matches in female soccer players. (2) Methods: Ten field players of the Chilean national football team (age 27 ± 3.4 years, height 162.8 ± 4.32 cm, weight 60.5 ± 4.6 kg, fat percentage 24.7 ± 1.62% and muscle percentage 49.2 ± 1.63%) participated in the study. Participants were compared across three FM before the world cup and three matches of the group stages in the WWC in June 2019. Both, ELO and ILO were recorded using GPS (Catapult Sports®, 10 Hz) and rating of perceived exertion (RPE), respectively. In addition, wellness was analyzed via personal questionnaire at 24 and 48 h after match. The intra subject difference was analyzed with a Student’s t-test for related samples. (3) Results: Moderate differences were observed between WWC and FM for total and relative total distance covered [TD and TDr, respectively] (p = 0.025, ES = −0.74 and p = 0.017, ES = −0.6). In addition, a non-significant (p = 0.088; ES = −0.43) larger high-intensity distance (HSR) was also found for WWC. Likewise, greater RPE was observed in WWC (p = 0.001; ES = −1.50) when compared to FM. Finally, significantly better wellness scores were shown for FM at stress ST24h, fatigue FT48h, and muscle pain MS48h (p = 0.038; ES = 0.72, p = 0.066; ES = 0.71; and p = 0.63; ES = 0.77) when compared to WWC matches. (4) Conclusion: It was concluded that ELO and ILO were greater at WWC soccer matches, whereas WS scores were better for FM. Moreover, ILO measures (i.e., TD, HSR and TDr) were greater in WWC, which could be at least in part, be the reason behind the differences in the values reported in the wellness questionnaires at 24 and 48 h after the match.

En respuesta a la aparición del COVID 19 y la pandemia ocasionada, los países tomaron medidas para manejar las curvas de infección. Han obligado a permanecer en confinamiento y esta estrategia afectó a diversos contextos, dentro de los cuales, se encuentra el ámbito deportivo, suspendiendo competiciones, partidos oficiales, entrenamientos en cancha, transmisiones deportivas, etc. Sin embargo, en el caso de los profesionales del fútbol, se mantuvieron en preparación física a través de plataformas tecnológicas. El objetivo de este trabajo es explorar los niveles de ansiedad rasgo, de sensación de bienestar y la relación entre ambas variables en futbolistas profesionales de cuatro clubes de Chile con el fin de contribuir al diagnóstico sobre cómo la crisis de Covid-19 puede haber afectado a la realidad deportiva en cuanto a la salud mental y emocional. Para ello se aplicó el STAI y el PERMA. Como resultados, los futbolistas investigados muestran niveles promedio de ansiedad rasgo y buen nivel de bienestar general. También se encuentra correlación entre ambos. Este estudio permite concluir que si bien la situación actual puede verse como amenazante, mantener las condiciones laborales y en actividad para un deportista parece ser clave para sentir cierto grado de control frente a la incertidumbre, así como estrategias de afrontamiento que permitan tener una alta sensación de bienestar. In response to the emergence of COVID 19 and the resulting pandemic, countries took steps to manage infection curves. They have forced them to remain in confinement and this strategy affected various contexts, within which is the sports field, suspending competitions, official matches, training on the field, sports broadcasts, etc. However, in the case of soccer professionals, they remained in physical preparation through technological platforms. The objective of this work is to explore the levels of trait anxiety, feeling of well-being and the relationship between both variables in professional soccer players from four clubs in Chile in order to contribute to the diagnosis of how the Covid-19 crisis may have affected sports reality in terms of mental and emotional health. For this, the STAI and PERMA were applied. As results, the investigated soccer players show average levels of trait anxiety and a good level of general well-being. There is also a correlation between the two. This study allows us to conclude that although the current situation can be seen as threatening, maintaining working and active conditions for an athlete seems to be key to feeling a certain degree of control in the face of uncertainty, as well as coping strategies that allow having a high sensation of wellness.

The prevalence of T2DM represents a challenge for health agencies due to its high risk of morbidity and mortality. Physical Activity (PA) is one of the fundamental pillars for the treatment of T2DM, so Physical Exercise (PE) programs have been applied to research their effectiveness. The objective of the study was to analyze the effects of PE methods on glycemic control and body composition of adults with T2DM. A systematic review without meta-analysis was performed, using the PubMed database. Quasi-experimental and pure experimental clinical trials were included, which were available free of charge and were published during 2010–2020. In the results, 589 articles were found and 25 passed the inclusion criteria. These were classified and analyzed according to the methods identified (AE, IE, RE, COM, and others), duration and variable(s) studied. It is concluded that PE is effective for glycemic control and body composition in adults with T2DM using different methods (AE, IE, RE, COM, and others), both in the short and long term. Adequate organization of PE components such as frequency, duration, volume, and intensity, is essential.

The learning styles are cognitive, affective, and physiological traits concerning how students perceive and process information, which is why their knowledge is relevant to enhance the methodologies of classes by teachers and learning strategies by students. Although there are several models that define and evaluate learning styles, a few of them have been used in physical education, highlighting the theories of Alonso, Gallego and Honey, the Kolb model, Herrmann’s theory of brain dominance and Model VAK. The few studies carried out in this sample show a preference for reflexive, divergent, dominated B (organized) and D (holistic) styles and for a kinesthetic style. Further studies are required on how students perceive and process information in various areas of education, with the aim of contributing with one more tool to improving the teaching-learning process.

En los últimos años los estudiantes universitarios han mostrado una disminución de los niveles de actividad física. Los objetivos del presente estudio fueron comparar y asociar parámetros de composición corporal y rendimiento físico en estudiantes universitarios de educación física de primer año. Participaron 72 estudiantes de ambos sexos (19 mujeres de 18.37 ± 0.51 años y 63 hombres de 19.16 ± 2.92 años). Se analizaron parámetros de composición corporal y rendimiento físico. Los resultados mostraron diferencias estadísticamente significativas entre hombres y mujeres en la masa corporal (p = .018), talla (p < .001), Σ6pliegues (p = .002), % de masa adiposa (p < .001), AF/SEM (p < .001), CMJ (p < .001), T10 (p < .001), T30 (p < .001), MYYTRI1 (p < .001) y Vo2máx (p = .043). Además, se encontraron correlaciones significativas (p < .05) entre niveles de Actividad Física semanal, parámetros de composición corporal y rendimiento físico. Se concluye que existen diferencias entre hombres y mujeres en relación con el volumen/número de horas de actividad física semanal, siendo esta mayor en hombres, composición corporal deficiente en mujeres junto con un menor rendimiento físico. Así mismo, el % de masa adiposa se asoció con medidas de condición física. A la luz de los hallazgos, parece necesario fortalecer los programas que promuevan la actividad física entre estudiantes universitarios. Estos resultados pueden servir de apoyo a las comunidades universitarias para reformar programas de desarrollo deportivo y hábitos de vida saludable. Palabras claves: Composición corporal, educación física, estudiantes, rendimiento físico. In recent years, university students have shown a decrease in physical activity levels. The aims of this study were to compare and associate body composition parameters and physical performance in first-year physical education university students. 72 students of both sexes participated (19 women, 18.37 ± 0.51 years old and 63 men, 19.16 ± 2.92 years old). Body composition and physical performance parameters were analyzed. The results showed statistically significant differences between men and women in body mass (p = .018), height (p < .001), Σ6skinfolds (p = .002), % fat mass (p < .001), PA/Week (p < .001), CMJ (p < .001), T10 (p < .001), T30 (p < .001), MYYTRI1 (p < .001) and Vo2max (p = .043). In addition, significant correlations (p < .05) were found between weekly Physical Activity levels, body composition parameters, and physical performance. It is concluded that there are differences between men and women in relation to the volume/number of hours of weekly physical activity, this being greater in men, poor body composition in women along with lower physical performance. Likewise, the % of adipose mass was associated with measures of physical condition. In light of the findings, it seems necessary to strengthen programs that promote physical activity among university students. These results can serve as support to the university communities to reform sports development programs and healthy lifestyle habits. Keywords: Body composition, physical education, students, physical condition.
