High-intensity functional training with an adequate and carbohydrate restricted hypocaloric diet promotes weight loss and cardiometabolic improvements

INTRODUCTION: Excess body weight and its comorbidities represent a major public health issue. Interventions based on diet and exercise have not only been shown to promote weight loss, but also improve overall health, including cardiovascular health. OBJECTIVE: This study aimed to evaluate the effects of a 12-week hypocaloric low-carbohydrate (CHO) diet coupled with high-intensity functional training (HIFT) on the cardiometabolic risk of overweight adults. METHODS: This is a randomized controlled trial. A total of 31 overweight adults participated in this study, divided into two groups based on the dietary intervention: reduced-CHO (R-CHO, ≤130 g/day; n=15) and adequate-CHO (A-CHO, >130 g/day; n=16). The cardiometabolic risk was assessed using lipidaemic, insulinemia, and glycaemic parameters. A two-way ANOVA with Bonferroni post hoc test was utilized to evaluate the effects of the intervention. A p-value < 0.05 was considered statistically significant. RESULTS: Participants from both groups displayed decreased low-density lipoprotein, very-low-density lipoprotein, total cholesterol, and triacylglycerol concentrations, as well as the number of risk factors for the metabolic disease after 12 weeks. The high-density lipoprotein (HDL) cholesterol concentration of both groups increased after 12 weeks, however, the result of the intragroup analysis revealed that a significant increase was only observed in the participants from the A-CHO group. CONCLUSION: Reduced or adequate CHO intake was both found to be effective in reducing cardiometabolic risk. However, improvements in HDL and final cardiometabolic classification risk indicated that CHO adequacy in the diet might be a better strategy associated with caloric restriction and HIFT.

Conocimiento sobre alimentación y nutrición después del desarrollo de actividades de educación alimentaria entre niños y adolescentes deportistas / Nutritional knowledge after conducting nutritional aducation activities between children and adolescents sportspeople / Conhecimento sobre alimentação e nutrição após o desenvolvimento de atividades de educação alimentar entre crianças e adolescentes esportistas

Evaluar el efecto de actividades de educación alimentaria en el conocimiento sobre nutrición básica y deportiva en niños y adolescentes deportistas. Métodos: participaron sujetos de ambos géneros, entre 9 y 19 años. Una muestra de 64 sujetos contestó al cuestionario antes del desarrollo de la intervención y los 27 sujetos que participaron de todas las actividades, volvieron a contestar al cuestionario después del desarrollo de la intervención. Para la evaluación de los cambios en su conocimiento sobre nutrición se aplicó el test de Wilcoxon. Resultados: Después de la intervención se observó un incremento significativo (p<0,05) en el porcentaje de aciertos para todos los temas del cuestionario (General, Nutrición Básica, Pirámide Alimentaria y Alimentación Deportiva).

This study aimed to evaluate the effectiveness of food education activities on the basic and sports nutrition knowledge among young sportspeople. Methods: subjects of both genders, with ages between 9 and 19 years. To assess the nutrition knowledge, 64 subjects answered a questionnaire before the development of nutrition education activities. After the intervention, 27 subjects, who attended to all of the meetings, answered the same questionnaire. To assess the increase on their nutritional knowledge after the intervention the Wilcoxon test were used. Results: After the intervention, there was a significant increase in the percentage of correct answers (p<0.05) in all of questionnaire themes (General, Basic Nutrition, Food Pyramid and Sports Nutrition).

Avaliar o efeito de atividades de educação alimentar no conhecimento sobre nutrição básica e esportiva de crianças e adolescentes esportistas. Metodologia: participaram indivíduos de ambos gêneros, entre 9 e 19 anos. Uma amostra de 64 indivíduos respondeu ao questionário na fase pré-intervenção destes, 27 indivíduos participaram de todas as atividades e responderam ao questionário de conhecimento em nutrição após o protocolo de intervenção. Aplicou-se o teste de Wilcoxon para avaliação da mudança. Resultados: Após a intervenção, observou-se um aumento significativo (p<0,05) no percentual de acertos em todos os temas do questionário (Geral, Nutrição Básica, Pirâmide alimentar e Alimentação esportiva).
