Quality of life in medical students who act in PBL methodology

Introduction: The learning takes place, mainly, by the integration of new knowledge acquired to previously existing ones, that is, by the elaboration of new information, in any of its previously analyzed forms. In the Problem Based Learning (PBL) method, constructivism is obtained at the expense of activation of prior knowledge, elaboration of new information, establishment of goals for self-directed study, and increament in the complexity of semantic networks in the final discussion of problem solving. Quality of life (QoL) can be considered as a subject of multiple approaches, contextualizations and applicability of which is used by several areas of knowledge. All the components that make up the quality of life can be measured and evaluated using quantitative instruments, including questionnaires, the main one being the WHOQOL-Bref, developed by the WHO, for having a cross-cultural evaluation methodology that allows uniform results. Objectives: To analyze in a global way the quality of life of medical students who work in the PBL model of the University of Ribeirão Preto (UNAERP). Methodology: A total of 90 students from the UNAERP medical school, aged over 18, enrolled in the 1st, 6th and 11th stages were included in this study. After signing the TCLE approved by the local CEP, the students answered a questionnaire based on the WHOQOL-bref. Results: A total of 55.5% of the women and 44.5% of the men with a mean age varying according to the stages (20 years, 1st stage, 22 years, 6th stage and 26 years in the 11th stage) were evaluated. When analyzing the degree of satisfaction of the students with regard to the PBL methodology, a percentage of 49.1% satisfaction was observed at the beginning of the course (1st stage), followed by 65.4% in the 6th stage and 77% at the end of the course (11th stage). The student’s satisfaction with the ability to perform the activities of his day-to-day recorded that in the first stage, 21.2% can carry out their activities with adequacy; in stage 6, 34.5% and in stage 11, 69.8% feel satisfied or very satisfied in this analysis. Students also had increased satisfaction with their academic performance when compared to the beginning and end of the course; on the other hand, in the intermediate phase, a percentage decrease can be observed as can be observed in the first stage: 42.8%; 6th stage: 33.5%; 11: 77%. Discussion and conclusions of the results: In this study, we measured the quality of life of university students of medicine at UNAERP and then made them reflect on how they deal with their personal, physical, social and mental issues throughout their training course. The PBL methodology enhances the need for independent study and focuses on student-led learning and improvement, which allows the student to evolve with a progressive improvement in the ability to perform day-to-day tasks and academic performance

Efecto de la suplementación de creatina sobre marcadores de daño muscular y desempeño físico en atletas de voleibo

Given creatine supplementation may attenuate exer-cise-induced damage and directly influence the ATP-CP system, the purpose of the study is to assess the effects of creatine (Cr) supplementation on muscle damage markers; creatine kinase (CK) and lactate dehydrogena-se (LDH), late-onset muscle pain (DOMS) and physical performance in volleyball athletes. A controlled study with a double blind model was performed. Fourteen participants supplemented (0.3 g / kg) of creatine or placebo during (loading phase) and (0.1 g / kg) during (maintenance phase). Significant differences were ob-served in total plasma creatine concentration (p <0.05), body weight (p = 0.047) and lower pain perception (p = 0.020), 24 hours (p = 0.001), 48 hours (p <0.001) and 72 hours (p = 0.011) in the creatine group. The evaluation of subjective perception of pain verified a significant difference in the creatine group (p <0.05). It was con-cluded that creatine supplementation, associated with carbohydrate consumption, attenuated the perception of pain in volleyball players after the muscle damage protocol.Dado que la suplementación con creatina puede atenuar el daño inducido por el ejercicio e influir directamente en el sistema ATP-CP, el propósito del estudio es evaluar los efectos de la suplementación con creatina (Cr) sobre los marcadores de daño muscular como; creatina quinasa (CK) y lactato deshidrogenasa (LDH), dolor muscular de aparición tardía (DOMS) y rendimiento físico en atletas de voleibol. Se realizó un estudio controlado con modelo doble ciego. Catorce participantes suplementaron (0.3 g / kg) de creatina o placebo durante (fase de carga) y (0.1 g / kg) durante (fase de mantenimiento). Diferencias significativas fueron observadas en la concentración plasmática total de creatina (p <0.05), peso corporal (p = 0.047) y menor percepción del dolor (p = 0.020), 24 horas (p = 0.001), 48 horas (p <0.001 ) y 72 horas (p = 0.011) en el grupo creatina. La evaluación de la percepción subjetiva del dolor verificó diferencia significativa en el grupo creatina (p <0.05). Se concluyó que la suplementación de creatina, asociada al consumo de carbohidratos atenuó la percepción de dolor en los jugadores de voleibol después del protocolo de daño muscular.Actividad Física y Deport

Effect of creatine supplementation on muscle damage markers and physical performance in volleyball athletes

Given that creatine supplementation may attenuate exercise-induced damage and directly influence the ATP-CP system, predominant in volleyball, the purpose of the study is to evaluate the effects of creatine (Cr) supplementation on muscle damage markers; creatine kinase (CK) and lactate dehydrogenase (LDH), delayed onset muscle soreness (DOMS) and physical performance in volleyball athletes.Fourteen volleyball players (under- 20 y) were divided into 2 groups: Creatine supplemented and Placebo. Double-blind controlled supplementation was performed using (0.3 g/kg) creatine or placebo for 7 days (loading phase) and (0.1 g/kg) for the next 4 days (maintenance phase). Before and after the supplementation phases, the players underwent Physical Performance Testing and blood sample collection to evaluate CK, LDH, and plasma creatine concentration.Dado que la suplementación con creatina puede atenuar el daño inducido por el ejercicio e influir directamente en el sistema ATP-CP, predominante en el voleibol, el propósito del estudio es evaluar los efectos de la suplementación con creatina (Cr) sobre los marcadores de daño muscular como creatina quinasa (CK) y lactato deshidrogenasa (LDH), dolor muscular de aparición tardía (DOMS) y rendimiento físico en atletas de voleibol. Se realizó un estudio controlado con modelo doble ciego, en el que catorce jugadores de voleibol (menores de 20 años) se dividieron en 2 grupos: creatina y placebo donde suplementaban (0.3 g/kg) de creatina o placebo durante 7 días (fase de carga) y 0.1 g/kg) durante los siguientes 4 días (fase de mantenimiento). Antes y después de cada fase de suplementación, los jugadores se sometieron a pruebas de rendimiento físico y recolección de muestras de sangre para evaluar CK, LDH y la concentración de creatina en plasma
