Ítem An active break program (ACTIVA-MENTE) at elementary schools in Chile: study protocol for a pilot cluster randomized controlled trial(Frontiers Media SA, 2023) Reyes-Amigo, Tomás; Ibarra-Mora, Jessica; Aguilar-Farías, Nicolás; Gómez-Álvarez, Nicolás; Carrasco-Beltrán, Hernaldo; Zapata-Lamana, Rafael; Yañez-Sepulveda, Rodrigo; Cortés, Guillermo; Rolle-Cáceres, Grissel; Bezerra, AndréaBackground: Physical inactivity is prevalent in childhood. Schools can be an ideal context to promote the regular practice of physical activity since children spend there a large part of the day. In this sense, an emerging and current trend is active breaks at school. This article presents a study protocol that seeks to assess the feasibility and effectiveness of an intervention with active breaks (ACTIVA-MENTE program) in a school context on physical activity, on-task classroom behavior, and the physical activity enjoyment in schoolchildren. Methods: The protocol includes children aged 10 to 11 years. Two groups will be randomized (intervention and control groups). The intervention group will use the active break program, ACTIVA-MENTE, which consists of the application of a 4-min, 30-s video with moderate to vigorous-intensity physical activity. These breaks will be taken 6 times a day in the classes for 6 weeks. The total physical activity will be measured with accelerometers (Actigraph wGT3X-BT), the on-task behavior through the Direct Behavior Rating Scale and the level of enjoyment through the Physical Activity Enjoyment Scale. Discussion: Previous research reported that active breaks have positive results in physical activity levels. This study will be one of the few to design active breaks through videos without depending on the presence of a physical education teacher and it can also provide new findings on the effectiveness of an active break’s structure (e.g., types of exercises and intensity) on the indicated outcomes. Expected results: It is expected that the ACTIVA-MENTE program can be a suitable program for school settings, potentially increasing physical activity levels, and the commitment to the task, as well as be a pleasant moment for the students.

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 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)
