La electroestimulación neuromuscular como mecanismo complementario en el entrenamiento deportivo de predominancia anaeróbica / Neuromuscular electro-stimulation as a complementary mechanism in sports training of anaerobic predominance

Introducción: La electroestimulación neuromuscular puede dar un valor agregado a los programas de ejercicio físico de rehabilitación, siempre y cuando se contemplen aspectos como los objetivos propios de cada persona, la tolerancia a la intensidad y las necesidades de recuperación y descanso. Así mismo, puede ser un elemento interesante a agregar en la planificación deportiva con miras a mejorar la recuperación, así como en el aumento del rendimiento físico. Objetivo: El objetivo principal de la presente investigación fue determinar los efectos del ejercicio combinado de electroestimulación neuromuscular y ejercicios de alta intensidad y corta duración en hombres sanos y físicamente activos sobre el índice de fatiga. Metodología: 34 hombres sanos, físicamente activos y estudiantes de educación física (19,4 ± 2,60 años) fueron aleatorizados y organizados en cuatro grupos: G1, programa de electroestimulación neuromuscular; G2, entrenamiento de alta intensidad y corta duración: G3, ejercicio combinado de alta intensidad y corta duración y, electroestimulación neuromuscular; y G4, grupo control. Se aplicó un test de Wingate antes y después del periodo de entrenamiento. Resultados: En el grupo G3 se evidencian aumentos en el rendimiento anaeróbico con diferencias significativas en la potencia promedio relativa al peso (p=0,027), con un aumento de 7,36% y con una disminución de 12,2% en el índice de fatiga (p=0,048). En el grupo G4 se evidencian disminuciones en el rendimiento, evidenciado a través de las diferencias significativas en la potencia media (p=0,030), con una disminución en el rendimiento de 6,32% y una disminución en el rendimiento en la potencia media relativa al peso con diferencia significativa (p=0,010) de 3,92%. Conclusiones: Un programa combinado de electroestimulación neuromuscular y ejercicio intervalico de alta intensidad mejora el rendimiento anaeróbico en la potencia media y relativa al peso, evidenciado a través de un test de Wingate. Así mismo, disminuye el porcentaje de caída del rendimiento anaeróbico, mostrando mejores resultados frente a un entrenamiento de solo ejercicio intervalico de alta intensidad

Introduction: Neuromuscular electrostimulation can add value to rehabilitation physical exercise programs, as long as aspects such as the objectives of each person, tolerance to intensity, and the needs for recovery and rest are considered. Likewise, it can be an interesting element to add in sports planning with a view to improving recovery, as well as increasing physical performance. Objective: The main objective of this research was to determine the effects of combined neuromuscular electrostimulation exercise and high intensity and short duration exercises in healthy and physically active men on the fatigue index. Methodology: 34 healthy, physically active, and physical education male students (19.4 ± 2.60 years) were randomized and organized into four groups: G1, neuromuscular electrostimulation program; G2, high intensity and short duration training; G3, combined exercise of high intensity and short duration, and neuromuscular electrostimulation; and G4, control group, A Wingate test was applied before and after the training period. Results: In the G3 group, there are increases in anaerobic performance with significant differences in the average power relative to weight (p=0.027), with an increase of 7.36%, and a decrease of 12.2% in the fatigue index (p=0.048). In the G4 group there are decreases in performance, evidenced through the significant differences in the average power (p = 0.030), with a decrease in performance of 6.32% and a decrease in the performance in mean power relative to weight with a significant difference (p=0.010) of 3.92%. Conclusions: A combined program of neuromuscular electrostimulation and high-intensity interval exercise improves anaerobic performance in mean power and relative to weight, evidenced through a Wingate test. Likewise, it decreases the percentage of drop in anaerobic performance, showing better results in comparison to training with only high-intensity interval training

Education to a Healthy Lifestyle Improves Symptoms and Cardiovascular Risk Factors – AsuRiesgo Study / Educação para um Estilo de Vida Saudável Melhora Sintomas e Fatores de Risco Cardiovasculares – Estudo AsuRiesgo

Background: Cardiovascular diseases are the current leading causes of death and disability globally. Objective: To assess the effects of a basic educational program for cardiovascular prevention in an unselected outpatient population. Methods: All participants received an educational program to change to a healthy lifestyle. Assessments were conducted at study enrollment and during follow-up. Symptoms, habits, ATP III parameters for metabolic syndrome, and American Heart Association’s 2020 parameters of cardiovascular health were assessed. Results: A total of 15,073 participants aged ≥ 18 years entered the study. Data analysis was conducted in 3,009 patients who completed a second assessment. An improvement in weight (from 76.6 ± 15.3 to 76.4 ± 15.3 kg, p = 0.002), dyspnea on exertion NYHA grade II (from 23.4% to 21.0%) and grade III (from 15.8% to 14.0%) and a decrease in the proportion of current active smokers (from 3.6% to 2.9%, p = 0.002) could be documented. The proportion of patients with levels of triglycerides > 150 mg/dL (from 46.3% to 42.4%, p < 0.001) and LDL cholesterol > 100 mg/dL (from 69.3% to 65.5%, p < 0.001) improved. A ≥ 20% improvement of AHA 2020 metrics at the level graded as poor was found for smoking (-21.1%), diet (-29.8%), and cholesterol level (-23.6%). A large dropout as a surrogate indicator for low patient adherence was documented throughout the first 5 visits, 80% between the first and second assessments, 55.6% between the second and third assessments, 43.6% between the third and fourth assessments, and 38% between the fourth and fifth assessments. Conclusion: A simple, basic educational program may improve symptoms and modifiable cardiovascular risk factors, but shows low patient adherence. .

Fundamentos: As doenças cardiovasculares são, atualmente, as maiores causas de óbito e incapacitação em todo o mundo. Objetivos: Avaliar os efeitos de um programa educativo básico para prevenção cardiovascular em uma população de pacientes ambulatoriais não selecionados. Métodos: Todos os participantes frequentaram um programa educativo de mudança para um estilo de vida saudável. Foram realizadas avaliações à admissão no estudo e durante o acompanhamento. Foram avaliados sintomas, hábitos, parâmetros do ATP III para síndrome metabólica e parâmetros da American Heart Association 2020 para saúde cardiovascular. Resultados: Foram incluídos no estudo 15.073 participantes com idade ≥ 18 anos. Foi feita a análise de dados dos 3.009 pacientes que completaram a segunda avaliação. Foram documentados perda de peso (de 76,6 ± 15,3 para 76,4 ± 15,3 kg, p = 0,002), melhora da dispneia aos esforços graus II-NYHA (de 23,4% para 21,0%) e III (de 15,8% para 14,0%), e redução na proporção de fumantes ativos atuais (de 3,6% para 2,9%, p = 0,002). Houve melhora na proporção de pacientes com níveis de triglicérides > 150 mg/dL (de 46,3% para 42,4%, p < 0,001) e de colesterol LDL > 100 mg/dL (de 69,3% para 65,5%, p < 0,001). Houve melhora ≥ 20% na métrica AHA 2020 no nível classificado como ruim para tabagismo (-21,1%), alimentação (-29,8%), e nível de colesterol (23,6%). Foi documentada grande evasão como indicador substituto para baixa adesão de paciente nas primeiras 5 consultas, sendo 80% entre a primeira e a segunda avaliação, 55,6% entre a segunda e a terceira, 43,6% entre a terceira e a quarta, e 38% entre a quarta e a quinta. Conclusão: Um programa educativo básico e simples pode melhorar os sintomas e fatores de risco cardiovasculares modificáveis, mas conta com pouca adesão por parte dos pacientes. .
