dc.description.abstractEl ejercicio, recreativo planificado, mejora capacidades físicas como la fuerza y resistencia brindando bienestar a sus practicantes, sin embargo, Suplementos Ergogénicos (SE) como Creatina, L-carnitina, Beta-alanina y Cafeína se utilizan para aumentar el rendimiento en estas capacidades físicas. Esto conlleva a que deportistas recreativos consuman suplementos con el fin de mejorar su desempeño deportivo. El objetivo del estudio fue evaluar los efectos de la suplementación ergogénica con Creatina, L-carnitina, Beta-alanina y Cafeína en el aumento de la fuerza y la resistencia en adultos entrenados, a través de una revisión sistemática con meta-análisis. La búsqueda fue realizada acorde a la guía metodológica Cochrane bajo lineamientos de informe Preferred Reporting Items For Systematic Reviews and Meta-Analyses (PRISMA),en ensayos clínicos, utilizando las bases de datos Pubmed, Embase, Central y Google académico. Se incluyeron estudios con una población mixta (>18, < 60 años) que fuera físicamente activa, los cuales consumieran Creatina, L-carnitina, Beta-alanina o Cafeína durante 28 días o más, sintetizando los datos a través de un meta-análisis pair-wise. Como resultados se obtuvieron 27 artículos en la revisión sistemática, 26 fueron parte del meta-análisis, de los cuales 16 estudios fueron sobre Creatina, 8 estudios para Beta-alanina, 1 estudio de L-carnitina y 2 estudios para Cafeína. Agrupando los estudios por intervención se realizó análisis de riesgo de sesgo y sensibilidad. En los resultados se evidenció que la creatina monohidratada tiene efectos diferentes acorde a las variables controlables como tipo de ejercicio, tiempo de consumo y dosis en donde presenta mayor o menor desarrollo de las capacidades físicas, sin embargo, se requiere un análisis a mayor profundidad en los efectos directos y beneficios. En cuanto a beta-alanina y Cafeína, el consumo de estos suplementos es considerado seguro sin embargo la efectividad de los mismos debe ir acorde a el tipo de actividad realizado. La L-carnitina evidencia una ligera tendencia de mejora bajo un análisis cualitativo de un estudio. En conclusión, el consumo de estos suplementos ergogénicos debe ser consumidos con mesura debido a que presentan efectos favorables acordes a factores individuales, por lo tanto, el consumo por sí mismo no es garantía de un efecto en las capacidades físicas. Se sugiere profundizar en relación de métodos de valoración de estas capacidades físicas, metodologías de entrenamiento y el periodo de ingestión. (Texto tomado de la fuente)spa
dc.description.abstractExercise, when planned recreationally, improves physical capacities such as strength and endurance, promoting well-being in its practitioners. However, Ergogenic Aids (EA) like Creatine, L-carnitine, Beta-alanine, and Caffeine are used to enhance performance in these physical capacities. This leads recreational athletes to consume supplements to improve their athletic performance.The objective of this study was to evaluate the effects of ergogenic supplementation with Creatine, L-carnitine, Beta-alanine, and Caffeine on increasing strength and endurance in trained adults, through a systematic review with meta-analysis. The search was conducted according to the Cochrane methodological guide under the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, in clinical trials, using the databases PubMed, Embase, Central, and Google Scholar. Studies with a mixed population (>18, < 60 years) that were physically active and consumed Creatine, L-carnitine, Beta-alanine, or Caffeine for 28 days or more were included, synthesizing the data through a pairwise meta-analysis. As results, 27 articles were obtained in the systematic review, of which 26 were part of the meta-analysis, 16 studies were on Creatine, 8 studies for Beta-alanine, 1 study for L-carnitine, and 2 studies for Caffeine. Grouping the studies by intervention, risk of bias and sensitivity analysis were performed. The results showed that creatine monohydrate has different effects according to controllable variables such as exercise type, consumption time, and dose, where it presents greater or lesser development of physical capacities, however, a deeper analysis of the direct effects and benefits is required. Regarding beta-alanine and caffeine, the consumption of these supplements is considered safe, however, their effectiveness must be according to the type of activity performed. L-carnitine shows a slight trend of improvement under a qualitative analysis of one study. In conclusion, the consumption of these ergogenic supplements should be consumed in moderation because they have favorable effects according to individual factors, therefore, consumption alone is not a guarantee of an effect on physical capacities. It is suggested to deepen the relationship of methods of evaluation of these physical capacities, training methodologies and the period of ingestion.eng
