This study aimed to compare the effects of the post-activation performance enhancement (PAPE) of two different types of warm-ups, unilateral and bilateral, on the performance in vertical jumping and agility of healthy subjects with strength training experience. In the study, 17 subjects (12 men and 5 women) performed two different PAPE protocols: unilateral squat (UT) and bilateral squat (BT). The height of the subjects’ countermovement jump (CMJ) and the subjects’ time to perform the T-agility test (TAT) were measured before and after executing the PAPE warm-up. The squats were performed at a velocity of 0.59 m·s⁻¹ with three sets of three repetitions, with a 3-min rest between sets and a 5-min rest after both uni- and bilateral PAPE warm-ups before taking the tests again. For statistical analysis, we applied ANOVA and calculated the effect size. The results showed that the PAPE for each case decreased the CMJ height but generated significant improvements in the total time taken for the T-agility test (p < 0.01); however, in both cases, the effect sizes were trivial. In conclusion, it is possible to observe that the PAPE, performed both unilaterally and bilaterally, negatively affects the performance in the vertical jump, showing moderate effect sizes. However, both PAPE protocols show performance benefits in agility tests, with a large effect size for the unilateral protocol and moderate for the bilateral protocol.

The objective of this study was to describe the state of strength and endurance in schoolchildren aged 7 to 10 years old from the city of Santiago de Tolú, Colombia, and to relate such values to their weights, heights, and body mass index (BMI) values. This was a descriptive, correlational, cross-sectional research study, whose quantitative statistical analysis was compared with studies conducted in Colombia and other countries. Strength was measured by the summation of the segmental dynamometry of the upper and lower limbs, and endurance was measured with a 5 min continuous run test. This is the first investigation to characterize variables related to physical education and sport in schoolchildren from Tolú. The information collected on the evaluated population may aid in its sustainable human development, since significant differences in height, weight, BMI, strength, and endurance were identified with respect to other national and international populations.

. El objetivo de este estudio fue determinar las diferencias de rendimiento en la fuerza máxima en sentadilla y banca plana, flexibilidad y composición corporal en los competidores de Crossfit® según su categoría. El diseño del estudio fue no experimental descriptivo de carácter transversal. Los participantes fueron 30 sujetos (edad 26.6 ± 5.2 años; masa 77 ± 9.4 kg; talla 172.8 ± 7 cm) practicantes de Crossfit® a nivel competitivo en las categorías intermedio, avanzado y elite. La fuerza máxima fue evaluada con la prueba de repetición máxima en sentadilla y banca plana; la flexibilidad se midió con el Flexitest y la composición corporal con bio-impedancia. Se encontraron diferencias estadísticamente significativas (p < .001) en la fuerza máxima al comparar las categorías competitivas. Estos valores de fuerza máxima aumentan a medida que avanza la categoría de competición. Sin embargo, no hubo diferencias en la flexibilidad, masa, porcentaje de grasa o porcentaje de masa muscular. Palabras clave: Rendimiento deportivo CrossFit®; entrenamiento funcional de alta intensidad; indicadores físicos; rendimiento de referencia; fuerza. The purpose of this study was to determine performance differences in maximal squat and flat bench strength, flexibility, and body composition in CrossFit® competitors according to their category. The study design was non-experimental descriptive in a cross-sectional nature. The participants were 30 subjects (age 26.6 ± 5.2 years; mass 77 ± 9.4 kg; height 172.8 ± 7 cm) who practiced CrossFit® at a competitive level in the intermediate, advanced, and elite categories. Maximum strength was determined using the flat bench chest press and squat in the one repetition maximum test; flexibility was determined using the Flexitest; and body composition was determined using bio-impedance. When comparing the competitive categories, statistically significant differences (p < .001) in maximum strength were discovered. These values increase as the competition category progresses. However, there were no differences in flexibility, mass, percentage of fat, or percentage of muscle mass. Keywords: CrossFit® sport performance; high-intensity functional training; fitness indicators; physical indicators; benchmark performance; strength.

Perceptual-motor capabilities, as core content in physical education at the elementary school level, require multiple learning environments where classes are aimed at strengthening body awareness in various motor actions. The objective of the study was to describe the level of development of perceptual-motor capabilities in schoolchildren in a municipality in Antioquia (Colombia) and its relationship with gender. Methodologically, it was a quantitative study with a non-experimental-descriptive design using non-probabilistic sampling of 82 fourth- and fifth-grade elementary school students. A sociodemographic profile and the CPM battery validated for the Colombian population (CVI=0.97) were used, and the information was processed using SPSS 27 and Jamovi 2.3.26 software. The results showed that, in terms of CPM classification, performance was low, with balance (82.9%), temporality (57.3%), and coordination (52.4%) showing the highest percentage of low performance. Furthermore, with regard to the gender variable, it was found that men performed better than women in the coordination tests (t=2.838; p<0.05; d=0.63). In conclusion, physical education teachers play a decisive role in monitoring and evaluating students' motor skills, since MPCs need to be stimulated through activities, games, and motor challenges that are put into practice.

Este estudio tuvo como objetivo caracterizar el nivel coordinativo de los estudiantes de básica secundaria de Chiquinquirá y Medellín a través de la aplicación del Test Motor Complejo (TMC) (Caminero, 2009). El diseño del estudio es de tipo descriptivo correlacional. En el estudio se evaluaron 2296 estudiantes (1145 mujeres y 1151 hombres) de secundaria (13.99 ± 1.66 años) (49.1 ± 10.8 Kg) (1.57 ± 0.1 m) (19.73 ± 9.17 % IMC). Se encontró que existen diferencias y correlación significativas en los resultados del TMC para la edad, género, ciudad e IMC (r < 0,000). El promedio del TMC fue de 29.02 segundos, con un rango entre 16.1 y 69 segundos. Se concluyó que el desempeño en el TMC de los escolares de estas dos ciudades es bajo y según un panel de expertos con el que se verifico a través de la V de Aiken (1985) es viable construir una herramienta de control para evaluar escolares a través de TMC ya que resulta confiable, objetivo y válido.

The objective of this study was to characterize the coordination level of high school students of Chiquinquirá and Medellín through the application of the Complex Motor Test (TMC) (Caminero, 2009). The study design is descriptive and correlational. In the study was evaluated 2296 high school students (1145 females and 1151 males) (13.99 ± 1.66 years) (49.1 ± 10.8 kg) (1.57 ± 0.1 m) (19.73 ± 9.17 % IMC). There were found significant differences and correlations in the results of TMC for age, gender, city and IMC (r < 0.000). The TMC average was 29.02 seconds, with a range between 16.1 and 69 seconds. It was concluded that the performance in the TMC of the schoolchildren of these two cities is low and according to a panel of experts with which it was verified through the V of Aiken (1985), it is viable to construct a control tool to evaluate schoolchildren through TMC since it is reliable, objective and valid.
