Abstract:
This research performed data mining for men and women powerlifters for the categories of Equipped Powerlifting, Classic Powerlifting, Equipped Bench Press, and Classic Bench Press, recognized by the International Powerlifting Federation (IPF). It then conducted a nonlinear regression analysis based on age versus mean scores in terms of Wilks Points, IPF Points, and IPF GoodLift Points to obtain the fitted curve and the age of peak performance for each category. Overall, the performance for all categories of men and women in powerlifting and bench press starts with exponential growth from youth until close to the third decade, showing a peak performance between 27.67 to 31.50 years of age, and then a linear decrease during maturation and older age. Comparisons between men and women and between equipped and classic athletes do not show meaningful differences in age of peak performance, suggesting the same biological clock in terms of aging. The sport of powerlifting offers a useful model to study human beings' growth, maturation, and aging.

Abstract:
The study aims to conduct a bibliographic and structured review based on the results found around the influence of balance on the quality of life of people with Down Syndrome (DS) in school and adult ages. For references searching, the following keywords were used as descriptors: “Down Syndrome,” “Balance,” and “Quality of life.” The words were always introduced in English and computerized databases; SCOPUS, WOS, and SPORTDiscus were used. Four inclusion criteria were introduced to limit the search: i) mentioning the influence of balance on the QOL of people with DS, ii) taking exclusively into consideration scientific articles, iii) having access to the full text or abstract, and iv) being written in English, Portuguese, or Spanish. In conclusion, the documents about the influence of balance in people with Down Syndrome address different research topics. Of the thirty-four articles located in the first search, seven of them meet the inclusion criteria. The reviewed scientific literature shows that the practice of physical exercise and specific training produce improvements in balance and the quality of life of people with Down syndrome, which allows establishing the recommendation to specifically train balance during physical activity sessions since there is evidence of positive effects for this group.

Abstract:
Introduction: At the neurophysiological level, the cerebellum, the basal ganglia, and the limbic system are important in the coordination and memory of movement. Objective: Understanding the processes involved in the sensoperceptive relationship of hearing and motor learning is a permanent motivation of different disciplines. Method: A documentary review is presented; it aims to analyze the relationship between auditory perception and motor learning using content analysis from the perspectives of audiology, medicine, and neurorehabilitation. The keywords and combinations taken into account were the following: hearing perception, learning, balance, coordination, and combinations hearing-learning, hearing-balance, and hearing-coordination. The databases and metasearchers Pubmed, Medscape, Trip, ScienceDirect, EBSCOhost, Pedro, Scielo, and Lilacs were used. Virtual libraries such as SINAB, Cochrane, University of Malaga, UsNational Library of Medicine, and National Institutes of Health were also consulted. We selected 22 articles that met the inclusion criteria. Results: A relationship was found between auditory perception and motor learning in the communication of auditory and motor sensory information at the level of processing in the cerebellum and basal ganglia, being a fundamental part of the retention and motor transfer. Conclusion: In the motor learning process involving the experience of movement, we propose the participation of hearing by integrating the perceived signals –visual, auditory, motor, and vestibular– that are concretized to improve learning, making it more effective, generating a more lasting memory.

Abstract:
Los niños y las niñas en edad escolar pueden pasar aproximadamente un 80 % de su jornada escolar haciendo uso de la silla. Debido a esta situación, diferentes estudios establecen una relación entre postura y problemas de salud. Señalan además, que las dificultades de escritura pueden afectar la percepción de las propias capacidades. Debido a estos resultados, se ha insistido en la importancia de inculcar hábitos posturales y grafomotrices adecuados desde edades tempranas. Los objetivos principales de este estudio fueron, por un lado, diseñar instrumentos de observación y recolección de datos de los patrones posturales y de grafomotricidad; por otro, validar dichos instrumentos mediante la opinión de personas expertas. Como objetivo secundario se consideró evaluar la consistencia interna del instrumento para valorar la postura de sedestación. En relación con el primer objetivo, ambos instrumentos mostraron valores altos de concordancia inter jueces en cuanto a la pertinencia y precisión de los ítems. Con respecto al segundo, los instrumentos fueron aplicados a una muestra de 93 niños y niñas de 1º y 5º curso de Educación primaria para evaluar la consistencia interna del instrumento postura. Los resultados de confiabilidad por dimensiones mostraron unos valores superiores a 0.7. Los instrumentos diseñados se presentan como herramientas útiles para valorar los patrones relacionados con la postura y la grafomotricidad y contribuir así a la detección de problemas asociados en niños y niñas en edad escolar. En conclusión, estos instrumentos pueden ofrecer directrices adecuadas para elaborar planes de trabajo destinados a atender las necesidades que presente el alumnado.

Abstract:
El propósito del estudio fue conocer las alteraciones en el estado de bienestar en periodo de confinamiento debido al COVID-19 en jugadores de fútbol profesional de la primera división B de Chile. Participaron 28 jugadores profesionales de fútbol varones, edad 26 ± 6.3 años, masa corporal de 74.2 ± 5.5 kg y estatura de 177 ± 0.05 cm. Se evaluó el grado de bienestar a través de un cuestionario (McLean et al., 2010) durante periodo competitivo y periodo de confinamiento de la temporada 2020. Se muestran diferencias estadísticamente significativas (p<0.05) entre el periodo competitivo y el periodo de confinamiento, en FT (t = 2.5; p = 0.0), SO (t = 2.71; p = 0.01), ES (t = 5.07; p = 0.0), EA (t = 1.82; p = 0.08) y T (t = 4.87; p = 0.0). Se reflejaron TE pequeños en las variables EA y DM (d = 0.7; d = 0.4 respectivamente), moderados en FT y SO (d = 1.0; d = 1.2 respectivamente) y muy grandes en ES y T (d = 2.1; d = 2.0 respectivamente). Los PC y CV entre periodos para las variables de bienestar fueron para FT 11% y 11.6%, para DM 5.3% y 13.1%, para SO 9.3%; 7.5%, ES 11.6% y 5.9, para EA 3.9%; 5.2%, y finalmente para T 8.1% y 4.0% respectivamente. Es posible concluir que el estado de bienestar en jugadores profesionales de fútbol se ve alterado en el periodo de confinamiento respecto al de competición, encontrándose cambios significativos en las variables FT, SO, ES y T, que coincidieron con los cambios de moderados a muy grandes de estas mismas variables, como también los PC fueron más grandes que el CV entre periodos; por lo que podríamos considerar estos cambios como reales, y que pudiesen ser un efecto atribuible al aislamiento obligatorio.

Abstract:
Introduction: The specialized literature has described the benefits of strength training on running speed. In the same way, stimulation of training based on eccentric contractions has been shown to be effective in improving this quality. Objective: To determine the effects of a training protocol based on the stretch-shortening cycle (SSC) and another on eccentric contractions (Nordic curl) on the running speed in 20 meters in adolescents from the Ñuble Region, Chile. Methodology: 42 school subjects were divided into experimental group (n = 22) and control group (n = 20). The training was developed for 6 weeks, with a frequency of 2 sessions/week, going from a volume of 8 to 32 repetitions of Nordic curl per session for the experimental group. The speed performance was evaluated in 20 meters. With photocells, the T Student's was applied to compare the pre- and post-intervention results, and the effect size (ES) was calculated. Results: Statistically significant differences were found (p <0.05) from the intervention in the experimental group (pre= 3,43 s. vs post= 3,15 s.), and a large ES (1,04). Conclusion: It is concluded that the eccentric training based on the application of Nordic Curl improves the performance of the running speed.

Abstract:
This study focuses on the analysis of perceived effort and time of moderate and vigorous activities in physical education classes, considering differences based on gender and the nutritional status of schoolchildren. A total of 95 children in 5th and 6th grade of primary school in the city of Coyhaique, Chile, participated in the study. The EPInfant scale was used to assess the perceived effort, and Actigraph GT3X+ accelerometers were used to determine the time of moderate and vigorous activity. No significant differences were found in the perceived effort by gender (p=0.144); instead, by nutritional status, obese students indicated a higher perceived effort than students with a normal weight (p=0.220). Regarding moderate and vigorous activities in Physical Education class, the boys were significantly more active than the girls (p=0.017). In contrast, normal-weight children were slightly more active at this intensity level, but this difference was not statistically significant (p=0.622). The effort in Physical Education classes has been perceived as more demanding by the obese students; for this reason, it is important to understand the physical and motor difficulties that this group presents. Likewise, girls have participated for a shorter time in moderate and vigorous intensities, being pertinent to look for didactic strategies to increase the time of their participation.

Abstract:
Aerobic exercise (AE) has been shown to be beneficial for the survival of patients with CAD and the decrease in interleukin 6 (IL-6). However, there is little evidence of the effect of concurrent training (CT). Purpose: To analyze the effect of AE versus CT on IL-6 in patients with CAD. Methodology: It was developed based on the PRISMA agreements; scientific articles were searched through electronic databases. The search terms (Boolean phrase) were the following: ("coronary artery disease" OR '' cardiac disease '' OR "cardiovascular disease") AND ('' exercise '' OR '' training '' OR "cardiac rehabilitation") AND ("IL-6" OR "Interleukin-6" OR "inflammatory markers") NOT ("animals" OR "rat"). The searches were conducted between August and December 2019. Results: A total of 2516 studies were reviewed, of which 10 studies that met the eligibility criteria were included. A total of 413 patients were analyzed. An improvement was found between 5% and 74% with the AE and between 2.3% and 58.8% with the CT. Both modalities significantly decrease IL-6, regardless of age, weekly training sessions, and the initial stage of patients with CAD; however, those studies that used a high intensity or a volume greater than 30 minutes showed greater benefits. Conclusion: Both EA and CT are beneficial in reducing IL-6 in patients with CAD. This systematic review leaves the possibility of continuing to investigate the behavior of high intensity in the decrease of IL-6.

Abstract:
There is currently an increase in inertial flywheel application in strength training; thus, it must be monitored by an accurate and reliable device. The present study tested: (1) the accuracy of an inertial measurement device (IMU) to correctly measure angular velocity and (2) its inter-unit reliability for the measurement of external load. The analysis was performed using Pearson Correlation and Intraclass Correlation Coefficient (ICC). The IMU accuracy was tested using Bland-Altman and the reliability with the coefficient of variation (CV). Ten elite-level football players performed ten series of 5 repetitions in a one-hand standing row exercise (5 series with each arm). A nearly perfect accuracy (ICC=.999) and a very good between-device reliability (Bias=-.010; CV=.017%) was found. IMU is a reliable and valid device to assess angular velocity in inertial flywheel workout objectively.

Abstract:
El fútbol como disciplina ha sido objeto de numerosas investigaciones que han permitido la potenciación de las cualidades de las personas deportistas para alcanzar el máximo rendimiento deportivo. El uso de nuevas herramientas ha permitido mejorar los procesos de selección de talentos y el desarrollo de las capacidades físicas, como es el caso de la dermatoglifia, que brinda información del genotipo de un individuo. El presente estudio pretende relacionar la composición corporal, la dermatoglifia y el consumo máximo de oxígeno en jugadores de fútbol categoría sub 20. La investigación fue cuantitativa, diseño no experimental, de tipo transversal. La muestra estuvo conformada por 22 futbolistas (edad 18 ± 1.1) de un club deportivo de Bogotá, a ellos se les realizó una valoración de composición corporal, se les calculó el somatotipo, se analizaron las huellas de las manos y se midió el consumo máximo de oxígeno con el Test Course Navette. Los resultados muestran predominio del somatotipo mesomorfo balanceado (53%), alta presencia de presillas “L” (66.36%), baja presencia de arcos “A” (1.82%) y un consumo máximo de oxígeno de 53.76 ± 3.73 ml/kg/min. Además, se encontraron relaciones significativas entre componentes dermatoglíficos D10-SCTL y el somatotipo endomorfo (p < 0.05), y entre el VO₂ máximo con somatotipo endomorfo y ectomorfo (p < 0.05). Se concluye que los futbolistas se caracterizan por tener una predisposición hacia la coordinación, la resistencia y la agilidad.
