Ítem Acute Effect of a Meditation-Oriented Physical Education Session on Stress Levels in School Children: A Randomized Controlled Study(Federacion Espanola de Docentes de Educacion Fisica, 2022) Yañez-Sepulveda, Rodrigo; De Zárate, Benjamín Ortiz; Tapia-Maldonado, Michel; González-Carreño, Jacob; Castro-Tapia, Lilian; Hurtado-Almonacid, Juan; Cortés-Roco, Guillermo; Zavala-Crichton, Juan Pablo; Olivares-Arancibia, JorgeThe main objective of this research was to identify the acute effect of a meditation-oriented Physical Education session on stress levels in schoolchildren aged 8 to 12 years, 34 Chilean schoolchildren participated, who were randomly divided into an experimental group (n18) and a control group (n16). During a Physical Education class, the experimental group carried out a 15-minute mindfulness meditation session, while the control group took a survey of healthy habits in sedentary behavior. Before and after the intervention the level of stress was measured with the Children's Daily Stress Inventory Test (IECI). The Shapiro Wilk test was used to determine the normality of the data, the t-Student test for related samples and the t-Student test for independent samples were used for comparison between groups, with the Cohen d test the effect size was calculated. The level of significance was established at p<0.05. A decrease in the total level of daily stress was observed with a moderate effect in the experimental group (PRE: 7.22 - POST: 6.17; P=0.037; TE=0.40), in the control group no effects were observed in the stress level (p>0.05) after the intervention. It is concluded that a short meditation session carried out during Physical Education class can provide a decrease in stress levels in schoolchildren, an aspect to be taken into account when improving learning at school. © Copyright: Federación Española de Asociaciones de Docentes de Educación Física (FEADEF) ISSN: Edición impresa.Ítem Análisis de datos antropométricos y madurativos para la delección de talentos en voleibol(Universidad de la Frontera, 2023-12) Yáñez-Sepúlveda, Rodrigo; Cortés-Roco, Guillermo; Olivares-Arancibia, Jorge; Reyes-Amigo, Tomás; Hurtado-Almonacid, Juan; García-De-alcaraz, AntonioEl proceso madurativo tiene una gran influencia sobre los factores antropométricos y las capacidades físicas del atleta, y por tanto, sobre el proceso de selección de talentos deportivos. El objetivo de este trabajo fue analizar el estado madurativo y las características antropométricas junto con la comparación de estos datos por sexo en una muestra de 39 jugadores jóvenes de voleibol dentro de un proceso de selección de talentos (19 damas de 14,88±1,05 años y 13 varones de 15,1 años). Se obtuvieron datos de edad cronológica, altura, peso, altura sentado, altura de la madre y padre, la edad pico de crecimiento, el “timing” o periodo de tiempo por encima o por debajo de la edad pico, altura al final del proceso madurativo, el porcentaje actual de altura máxima, los centímetros restantes y el estado madurativo (pre-púber, púber o pos-púber). Los jugadores mostraron una mayor altura en el momento de las mediciones (179,92±6,87 vs 171,05±4,80; p<0,001), así como una mayor altura final calculada (189,46±3,73 vs 178,52±5,17; p<0,001), en comparación a las jugadoras. El pico en la velocidad de crecimiento también fue superior en los jugadores (14,56±0,44 vs 12,60±0,57; p<0,001), aunque su timing era inferior al de las jugadoras (0,531±1,19 vs 2,27±0,64; p<0,001). Esto se debió a un mayor porcentaje de jugadores masculinos en estados puberales, incluyendo un jugador en estadio pre-puberal, mientras que fue abundante la presencia de jugadoras en estado pospuberal. Estos datos reflejan la gran cantidad de jugadores que tienden a estar en periodos avanzados de madu ración en procesos de selección de talentos. Por tanto, entrenadores y seleccionadores deben contemplar estas variables para evitar sesgos en el proceso de identificación del talento deportivo.Ítem Efectos de los juegos didácticos en la clase de Educación Física en el logro de aprendizaje trasversal sobre hábitos de higiene escolar en estudiantes de 6 y 7 años(Federación Española de Docentes de Educación Física, 2023) Yáñez-Sepúlveda, Rodrigo; Gudenschwager-Sauca, Karin; Añasco-Rodríguez, Patricio; Trigo-Alvarez, Jaime; Muñoz-Rojas, Carlos; Olivares-Arancibia, Jorge; Hurtado-Almonacid, Juan; Cortés-Roco, GuillermoIntroducción: La presente investigación tuvo como objetivo determinar el efecto del uso de juegos didácticos en las clases de Educación Física en el logro de aprendizaje transversal significativo sobre hábitos de higiene en estudiantes de 6 y 7 años. Métodos: Estudio cuasiexperimental, diseño metodológico cuantitativo, la muestra de 42 alumnos de ambos sexos con los cuales se llevó a cabo un programa de intervención por 4 semanas consecutivas. Se buscó determinar cuán influyente puede ser el juego en el aprendizaje significativo del niño en las clases de Educación Física por medio de una encuesta aplicada pre y post intervención, la cual constaba de 32 preguntas en donde se tenía que valorizar según frecuencia de ejecución: Siempre, Casi siempre, Ocasionalmente, Casi nunca, Nunca. Resultados: Los resultados de las diferentes variables se presentan en los datos a continuación tomando en cuenta la comparación previa y posterior a la intervención. Se observaron diferencias significativas durante las 4 semanas de intervención en Higiene de manos (PRE: 18,6 ± 4,6 POST: 27,9 ± 2,4; P= 0,000; TE= -2,45) se encontraron efectos positivos de la intervención; Higiene de Bucodental (PRE: 18,2 ± 4,5 POST: 23,6 ± 3,1; P= 0,000; TE= -1,39) se encontraron efectos positivos de la intervención.; Higiene Corporal (PRE: 16,3 ± 4,2 POST: 25,1 ± 2,3; p= 0,000; TE= -2,59); Higiene de Social (PRE: 13,0 ± 4,8 POST: 20,2 ± 2,1; p= 0,000; TE= -1,94) se encontraron efectos positivos de la intervención; Higiene total (PRE: 66,0 ± 16,3 POST: 96,8 ± 5,7; p= 0.000; TE= -2,47) se encontraron efectos positivos de la intervención. Conclusión: el programa de intervención en las clases de educación física, a través del juego generó efectos significativos en el aprendizaje transversal sobre los hábitos de higiene, lo que nos motiva a utilizar y recomendar este método de enseñanza para ser utilizado en impartir nuevos hábitos, valores y principios. En las cuatro variables, hábitos de higiene de manos, bucodental, social, y corporal, se tuvo una mejora significativa en los 42 alumnos y alumnas de la institución educativa. Con esto podemos dar cuenta que es un contenido que podemos trabajar sin problema durante las clases de Educación Física por medio de juegos didácticos.Ítem Effects of Post-Activation Performance Enhancement on Competitive Swimmers’ Performance: A Systematic Review(OVS LLC, 2023-06) Mendoza-Sagardía, Edgardo; Bezerra, Andrea; Correia de Freitas, Laura; Gómez-álvarez, Nicolás; Hurtado-Almonacid, Juan; Páez-Herrera, Jacqueline; Sepúlveda-Figueroa, Felipe; Ibarra-Mora, Jessica; Yáñez-Sepúlveda, Rodrigo; Reyes-Amigo, TomásStudy purpose. The aim of this systematic review was to evaluate the effects of post-activation potentiation/post-activation performance enhancement (PAP/PAPE) warm-up protocols on swimmers’ performance. Materials and methods. The searches were carried out on the electronic database PubMed, Scopus, Web of Science, and EBSCO platforms. Studies from 2010 to May 2022 related to PAP/PAPE and its effect on swimming performance in swimmers aged between 18 and 35 were included. Results. Nine of 333 studies were included in this review. In two studies, peak thrust improved by 13% to 19% for PAP vs non-PAP and by 3% on performance. One study showed improvements by 10% on speed and speed fluctuation in 25 m all-out PAP vs non-PAP. Rate of force development (RFD) 15 m maximum effort was higher for dry land warm up (DLWU) than swimming warm up (SWU). One study had higher velocity in 5 m for repetition maximum warm-up (RMWU) and eccentric fly-wheel warm-up (EWU) vs SWU. One study demonstrated enhancements for upper-body PAP (UBPAP), low-body PAP (LBPAP) and MIX (UBPAP/LBPAP) vs warm up based on general exercises (GEN) in time to 25 m freestyle (T25FS). Two studies found improvements for band squats PAP compared to swimming specific warm up (SSWU) in time to 15 m. One study demonstrated that PAP trial (PAPT) was faster than control time trial (CTT) in 50 m and 100 m freestyle trial. Dive velocity (DV) was faster for RMWU/EWU vs SWU. One study showed significant increase in power vertical force (PVF) and power horizontal force (PHF) after the PAP vs SSWU. Conclusions. PAP/PAPE is one more tool that can be beneficial if adapted to the conditions of swimmers, controlling fatigue levels, where it is performed (land or water), and most importantly, described by many coaches, the specificity of movement. © 2023, OVS LLC.

(1) Background: This study aimed to assess the impact of a physical education program, based on a model of structured and unstructured physical activity, on the motor development of kindergarten students at a private school for girls in Con Con, Chile. (2) Methods: Thirty-four female students were divided into two groups, one participated in structured physical activity and the other in unstructured physical activity, and both groups then underwent a 12-week intervention. The Test of Gross Motor Development-2 (TGMD-2) was utilized to evaluate motor behaviors, and the data were analyzed using descriptive statistics and relative frequencies. The Wilcoxon test was used to compare differences at the beginning and end of the intervention, while the Whitney–Mann U test was used to determine differences between groups. (3) Results: Statistically significant differences were observed in the overall group when comparing the start and end of the intervention for total motor development (p = 0.001), locomotion skills (p = 0.018), and object control (p = 0.001). However, no significant differences were found between the two types of intervention activities. (4) Conclusions: This study suggests that both structured and unstructured physical activity interventions enhance overall motor development, particularly in the dimensions of locomotion and object control. The results indicate that unstructured physical activity interventions may lead to better outcomes in motor development tests compared to structured interventions. © 2023 by the authors.Ítem Intensity and level of physical activity in the diabladas of the festival of La Tirana in Chile(Federación Española de Docentes de Educación Física, 2023) Yáñez-Sepúlveda, Rodrigo; Cortés-Roco, Guillermo; Hurtado-Almonacid, Juan; De Souza-Lima, Josivaldo; Olivares-Arancibia, Jorge; Reyes-Amigo, Tomás; Zavala-Crichton, Juan PabloThe objective was to analyze the intensity and level of physical activity in diabladas during the festival of La Tirana in Chile. The study was non-experimental, cross-sectional, exploratory, descriptive and comparative. Fifty dancers from a Chilean diablada (30 women and 20 men) participated. The evaluations were carried out during the religious festival of La Tirana in northern Chile. Actigraph GTX-3 model accelerometers were used to quantify the study variables and were installed at the waist. The dancers had effective dance days between 3 and 5 hours/day. The average intensity per hour of dancing was 3.1 ± 1.0 METs, the percentage of dance intensity to moderate to vigorous intensity (AFMV) was 46.4% ± 2.7%; the average number of steps per hour was 3124 ± 178 and the time in moderate to vigorous activity (AFMV) ranged from 83.1 to 138.5 min per day. Differences in very vigorous physical activity were found between men and women (F=9.57; p=0.003; n2p= 0.127). Diabladas dancers present high levels of physical activity during the religious festival of La Tirana in Chile. Every day the dancers exceed the international recommendations for physical activity, which can generate benefits in health and quality of life. © Copyright: Federación Española de Asociaciones de Docentes de Educación Física (FEADEF)Ítem The teaching work of female physical education teachers during context of the COVID19 pandemic.
