Meta-análisis de estudios observacionales y experimentales.","authors":"Lucia Florio, Santiago Rivoir","doi":"10.6018/sportk.535001","DOIUrl":"https://doi.org/10.6018/sportk.535001","url":null,"abstract":"Introduction: Physical exercise affects the morphology and function of the left atrium. Elite athletes have increased volume without increasing stiffness. The effect of exercise on the atria of the general population is less well known.\u0000Objective: To evaluate the effect of aerobic exercise on the anatomy and function of the left atrium. Main objective: compare left atrial volume indexed to body surface area; secondaries: to compare ejection fraction and left atrial peak longitudinal strain, E/e´ ratio and new atrial fibrillation in a population that practices aerobic exercise for at least 4 weeks vs non-active.\u0000Method: Meta-analysis of observational or experimental studies. Excluded: subjects with baseline atrial fibrillation, non-aerobic exercise; elite/professional athletes. Keywords: “physical exercise AND left atrial function”, until 2/21/2022 in Pubmed, Scielo, clinicaltrials.gov and hand-search.\u0000Results: Eleven studies included in main outcome; 789 subjects, median age 52 years; female sex 24%. Main outcome (only statistically significant): left atrial index volume 2.65 ml/m2 ˃ in the exercise group (p=0.006). No results were found for incidence of atrial fibrillation.\u0000Conclusions: In the general population, aerobic exercise favors dilation of the left atrium. The relevance is doubtful due to contradictory and non-significant results on atrial stiffness.\u0000 Introducción: El ejercicio físico afecta la morfología y función de la aurícula izquierda. Atletas de élite tienen aumento del volumen sin aumentar la rigidez.

Objetivo primario: comparar volumen de aurícula izquierda indexado a superficie corporal; secundarios: comparar fracción de eyección y strain longitudinal pico de aurícula izquierda, relación E/e ́ y nueva fibrilación auricular en población que practique ejercicio aeróbico por al menos 4 semanas vs no activos.\u0000Método: Meta-análisis de estudios observacionales o experimentales. Se excluyeron sujetos con fibrilación auricular basal, ejercicio no aeróbico; atletas de élite/profesionales.

This has resulted in the best performance in various competitions and sports, and one of the modern technologies is the field of genetics technology. The aim of this study was to build a model for measuring the level of physical and skill performance of volleyball players according to the variance level of the MCT1 gene and basic biochemical indicators. The researchers used the descriptive approach. The sample of the study consisted of 21 advanced volleyball players from the Middle Euphrates region participating in the Men's Premier League for the 2020-2021 sports season. To solve the research problem, we used the following variables: the MCT1 gene, chemical indicators of blood (LDH enzyme, the concentration of lactic acid in the blood, PH of blood), and the level of physical and skill performance in volleyball. The researchers used the Statistical Package for the Social Sciences (SPSS) for data analysis. In terms of the variance level of the MCT1 gene and various blood chemical indicators for the degree of performance of the skillful physical effort in volleyball, three prediction rates (models) were obtained. The amounts of variability of the MCT1 gene in the research sample varied between high and low levels. The researchers suggest using the model for prediction rates to determine the performance level of volleyball players and stressing genetic study of the MCT1 gene in volleyball players to facilitate the selection of players, particularly juniors.","PeriodicalId":44430,"journal":{"name":"Sport TK-Revista Euroamericana de Ciencias del Deporte","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2022-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84157686","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}

The researchers used the experimental method in the style of two equal groups for its suitability to the nature of the research. The research sample was determined by 18 table tennis players (aged 8-10 years old), from the specialized school in the Ministry of Youth and Sports, Baghdad, for the academic year 2021. We randomly divided the sample into two equal groups (experimental and control), each group comprising 6 players. The experimental group used the direct playing method, while the control group used the traditional method. In order to determine the skill test for the accuracy of the table tennis serve skill in the sample, the researchers used the test of the accuracy of the table tennis serve. The results of our study showed that there were statistically significant differences between the pre- and post-test results for the experimental group on the study variable, in favor of the post-test (t = 6.27, p < 0.05). We also found statistically significant differences in the results of the pre- and post-test results for the control group, in favor of the post-test (t = 5.16, p < 0.05). We also had statistically significant differences between the experimental and control group in the post-test results, in favor of the experimental group (t = 5.34, p < 0.05).

The results showed that there is a positive and statistically significant correlation between overall harmonic abilities and the level of skill performance (p<0.05). The results also showed that most harmonic abilities (rhythmic ability, ability to adapt to changing situations, and ability to link movement) have an impact on the skill performance of the offensive blocking of positions 2, 3 and 4 (p<0.05). The authors recommend the use of harmonic abilities due to their positive impact on skill performance in volleyball.
