“…To compare the physical performance variables based on the type of intervention used the one-way ANOVA test with Bonferroni’s post hoc . The effect size (ES) was calculated with Cohen’s d ( Cohen, 1992 ) considering a small (0.20–0.49), moderate (0.50–0.79) or strong (>0.80) effect the formula used was d = (M 1 -M 2 )/SD ( Rendón-Macías et al, 2021 ). In all cases, a significance value of p < 0.05 was established.…”

This study aims to compare the effects of standard warm-up versus warm-up using stretching exercises on the physical performance of male youth soccer players. Eighty-five male soccer players (age: 10.3 ± 4.3 years; body mass index: 19.8 ± 4.3 kg/m2) were assessed for countermovement jump height (CMJ, cm), 10 m, 20 m and 30 m running sprint speed (s) and ball kicking speed (km/h) for the dominant and non-dominant leg under five (randomized) warm-up conditions. Using 72 h of recovery between conditions, the participants completed a control condition (CC) and four experimental conditions, including static stretching (SSC), dynamic stretching (DSC), ballistic stretching (BSC), and proprioceptive neuromuscular facilitation (PNFC) exercises. All warm-up conditions had a duration of 10 minutes. The main results indicate that no significant differences (p > 0.05) were found between warm-up conditions compared to CC in CMJ (CC = 28.1 ± 4.9; SSC = 28.4 ± 4.9; DSC = 30.9 ± 4.8; BSC = 30.9 ± 5.2; PNFC = 28.4 ± 5.0), 10 m sprint (CC = 2.42 ± 0.4; SSC = 2.50 ± 0.4; DSC = 2.30 ± 0.3; BSC = 2.27 ± 0.3; PNFC = 2.53 ± 0.4), 20 m sprint (CC = 5.42 ± 0.9; SSC = 5.59 ± 0.9; DSC = 5.37 ± 0.9; BSC = 5.40 ± 0.9; PNFC = 5.44 ± 0.9), 30 m sprint (CC = 8.05 ± 1.3; SSC = 8.27 ± 1.3; DSC = 8.01 ± 1.3; BSC = 8.00 ± 1.3; PNFC = 8.12 ± 1.3), ball kicking speed for dominant (CC = 56.2 ± 4.9; SSC = 55.3 ± 5.2; DSC = 56.9 ± 5.8; BSC = 57.3 ± 5.8; PNFC = 55.7 ± 5.2) and non-dominant leg (CC = 52.8 ± 3.4; SSC = 51.8 ± 4.6; DSC = 53.5 ± 5.4; BSC = 53.6 ± 4.9; PNFC = 52.5 ± 4.0). In conclusion, compared to standard warm-up, stretching-based warm-up exerts no effect on male youth soccer players jump height, sprint speed and ball kicking speed.

“…La diferencia media de 10.769 indica una mejora considerable en la enseñanza de la comprensión lectora a nivel crítico como resultado del programa de capacitación, siendo éste el de mayor efecto, el nivel literal e inferencial de 9.769 y 10.615 respectivamente con una significancia p8 <.001), Estos resultados se respalda por el intervalo de confianza del 95 %, que incluye a las diferencias de medias en todos los niveles. El tamaño del efecto, expresado por d = 4.328, es extraordinariamente grande y práctico (Rendón-Macías et al, 2021). Este resultado indica que la capacitación tuvo un impacto positivo y significativo en la eficacia de los docentes en la enseñanza de la comprensión lectora a nivel crítico.…”

La comprensión lectora es la capacidad de entender lo que se lee, y es esencial para el aprendizaje y la participación social. El estudio buscó evidenciar que un programa basado en estrategias didácticas aplicado a docentes peruanos mejora la compresión lectora. La investigación fue aplicada, diseño experimental, de tipo pre experimental, desarrollado en docentes peruanos de educación básica regular (nivel primario), con quienes se desarrolló el programa, aplicando previamente un pretest elaborado por la autora, el mismo que contó con validez de contenido por juicio de expertos y fiabilidad mediante coeficiente Alpha de Cronbach en una muestra piloto, garantizándose su aplicabilidad, al término se aplicó nuevamente el test. Los resultados evidenciaron la efectividad del programa al demostrar que su aplicación mejora las competencias para una mejor comprensión lectora (t=23.962; ∆M=31.154; p<.001 y d=6.646); por lo que debe aplicarse en general a todos los docentes de básica regular de escuelas peruanas.

“…This method carefully controls Type I error, and it is a better alternative than the Sobel test. Regarding determination coefficients, R 2 values ranging from .04 to .24 are considered small effects, .25 to .63 as medium, and ≥ .64 as large (Rendón-Macías et al, 2021).…”

The current study sought to test hypotheses derived from the social cognitive model of career self-management (CSM; Lent & Brown, 2013) applied to the process of career exploration and decision-making. We examined how well personality traits, contextual factors, and social cognitive predictors, collectively, account for exploration behavior and career decision-making outcomes. Specifically, we determine the relationships between personality traits with career decision self-efficacy, career goals, and decisional criteria in a sample of 302 high school students. The participants completed domain-specific measures of four personality traits (conscientiousness, intellect/openness, extraversion, and neuroticism), social support, self-efficacy, outcome expectations, goals, level of career indecision, and decisional anxiety. The model fit the data well overall, though certain predictors were linked to the criterion variables only indirectly via mediated pathways. The structural equation model analysis suggested, consistent with previous studies, that the contribution of personality on career exploration and decision-making was mediated by sociocognitive mechanisms. Multiple group analysis suggests that neither sex nor the type of institution (state/private) that students attend determines the relationships among the variables of the proposed theoretical model. Limitations, further research, practical implications, and methodological implications for the CSM model are discussed.
