Los resultados del análisis de ecuaciones estructurales encontraron que la calidad en la presentación de las tareas se relacionaba de manera positiva y significativa con la satisfacción de las tres necesidades psicológicas básicas (βautonomía = .59, p < .001; βcompetencia = .30, p < .001; βrelación = .60, p < .001). A su vez, la satisfacción de las necesidades de autonomía (β = .31, p < .001), competencia (β = .16, p < .001) y relación (β = .22, p < .001), se asociaron positiva y significativamente con la satisfacción con la vida de los deportistas, mientras que la relación de las tres necesidades psicológicas fue negativa y significativa con el burnout deportivo (βautonomía = -.16, p < .001; βcompetencia = -.14, p < .001; βrelación = -.30, p < .001).

This study tested a model that analyzed the associations between the task presentation provided by the coach, the satisfaction of athletes' psychological needs for autonomy, competence and relatedness, and satisfaction with life and sport burnout. A total of 706 soccer players (530 men and 175 women; Mage = 17.76 years; SD = 2.18) belonging to different teams representing a public university in the state of Nuevo León, Mexico, participated. The results of the structural equation analysis found that the quality of task presentation was positively and significantly related to the satisfaction of the three basic psychological needs (βautonomy = .59, p < .001; βcompetence = .30, p < .001; βrelatedness = .60, p < .001). In turn, satisfaction of the needs for autonomy (β = .31, p < .001), competence (β = .16, p < .001) and relatedness (β = .22, p < .001), were positively and significantly associated with athletes' life satisfaction, whereas the relationship of the three psychological needs was negatively and significantly associated with sport burnout (βautonomy = -.16, p < .001; βcompetence = -.14, p < .001; βrelatedness = -.30, p < .001).

Objective: To determine the incidence and effectiveness of the tactical formations applied in the results of soccer matches played in cities at altitudes between 2500 and 3250 meters above sea level. Method: Non-experimental quantitative study of correlational approach, in a study sample of 123 soccer matches played between 2020 and 2021 under these conditions, analyzed through the Instat Scout platform and the opinion of experts to determine the tactical formations of visiting teams residing at sea level, taking into account the effectiveness of points and goals obtained. Results: There were no differences between the means of goals scored and goals conceded by tactical formation; however, at a descriptive level, there was evidence of greater effectiveness in the 4-3-3 tactical formation due to the number of matches analyzed in relation to a higher mean of goals scored and a lower mean of goals conceded; statistically, there was a high positive correlation between the 1-3-4-3 tactical formation and goals scored with a significance level of P<0.01. Conclusion: The data obtained shows that the formations that use a line of 4 defenders obtain better results in comparison with the formations that use only 3 defenders, being the 1-4-3-3-3 tactical formation the one that obtained better results in contrast with the 1-3-5-2 formation that obtained the worst results.\u0000Keywords: Altitude; Tactical Formations; Away games; Points and goals effectiveness; Instat Scout Platform.","PeriodicalId":52896,"journal":{"name":"Retos de la Direccion","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88331063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the important health benefits of regular physical activity and the recommendations made by the World Health Organization, high levels of sedentary lifestyles are observed in adolescents. Considering that physical education has the potential to help increase physical activity directly and indirectly, it is important to implement high-quality interventions aimed at promoting the acquisition of physical activity habits and active lifestyles during adolescents’ free time. A systematic review was conducted, according to the PRISMA standards, of interventions in physical education between 2012 and 2022, focusing on the effect on physical activity during free time in adolescents of the metacognitive variables (planning, self-control, evaluation, and reflection) and motivational (effort and self-efficacy) of self-regulated learning, according to Zimmerman's social cognitive model.

This study uses a quantitative descriptive method, participants in this study were female and male adolescent athletes obtained 42 participants, divided into 20 males and 22 females. Data on muscle endurance and strength were obtained by measuring the leg and back dynamometer, while the spike hit results collected from The Volleyball Test Skills for Smasher and performance were obtained using observation using a range of points 1-4, which is based on five spike phases: Initial Attitude, Initial Motion, Contact Motion, Follow through Motion, and Ball Placement. Data analysis used ANOVA test and simple regression. The results showed that the performance was significantly increased by the strength of the back muscles (p = 0.005 < 0.05) and abdominal muscles (p = 0.012 < 0.05), while the other components were supportive but not significant. Likewise, the strength of the inner leg muscles (p = 0.010 < 0.05) which has a very significant level of influence (p < 0.01) on the spike results. Strengthening back muscle and abdominal muscle endurance need to be the focus of the training program for young volleyball athletes because they are needed during spike movement and inner leg muscle strength is needed to obtain maximum spike jumps.\u0000Keywords: spike; endurance; strength; muscle; young athletes; volleyball","PeriodicalId":52896,"journal":{"name":"Retos de la Direccion","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76267836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
