Resumo
Objetivos: Analisar, após uma sessão de treinamento de Muay Thai (MT), i) a recuperação da frequência cardíaca e a hipotensão pós-exercício de adolescentes com sobrepeso/obesidade. Bem como analisar, após 16 semanas de treinamento de MT, ii) os efeitos sobre a composição corporal em adolescentes com sobrepeso/obesidade, além de iii) os efeitos sobre os parâmetros cardiovasculares e a modulação autonômica cardíaca (MAC) de adolescentes com sobrepeso/obesidade. Métodos: A amostra foi composta por 33 adolescentes com sobrepeso/obesidade com idade entre 10 e 17 anos em que foram realizadas avaliações de: i) Composição corporal total e por segmento (massa magra, gorda e óssea); ii) Aferição da pressão arterial sistólica (PAS) e diastólica (PAD) e frequência cardíaca (FC) de repouso; iii) MAC; iv) Frequência alimentar; e v) Prática de atividade física. O treinamento de MT foi de 16 semanas, três vezes na semana, durante uma hora e meia por dia. O grupo controle (GCO) não realizou o treinamento. Esse trabalho apresenta o resultado de três estudos, sendo utilizados os testes Shapiro-Wilk, Kolmogorov Smirnov, teste t independente, ANOVA de medidas repetidas com ajustes por fatores de confusão e tamanho do efeito. Foi utilizado o Software SPSS e p-valor<5%. Resultados: Comparando o momento inicial com a recuperação de uma sessão de MT, a PAS reduziu nos meninos após 20 min e 30 min, e nas meninas após 20 min. Na PAD houve redução nas meninas logo após a sessão e 10 min, e em ambos os sexos logo após a sessão e 10 min. Não houve a recuperação da FC. Após 16 semanas de treinamento de MT houve diferença significativa no efeito grupo para as variáveis de massa corporal, gordura corporal (GC), massa gorda (MG) total, MG de braços, gordura de tronco (GT) e gordura andróide. Já a massa magra (MM) total e de pernas apresentou efeito significativo de interação, no qual o grupo MT aumentou mais comparado ao GCO. Na massa óssea, tanto conteúdo, quanto densidade, não houve diferenças significativas. Após 16 semanas, o grupo MT reduziu significativamente a FC no efeito interação, quando comparado ao GCO. Além disso, o grupo MT, no geral, apresentou tendência em melhorar a MAC e a reduzir GC. Conclusão: Pode-se concluir que uma sessão de MT proporcionou efeitos hipotensores na PA. Além de 16 semanas da prática de MT aumentar significativamente a MM total e de pernas, reduzir a FC, além de apresentar tendência a reduzir a GC no geral, bem como melhorar a MAC.
Objective: To analyze, after a Muay Thai (MT) training session, i) the recovery of heart rate and post-exercise hypotension of overweight/obese adolescents. As well as analyzing after 16 weeks of MT training, ii) effects on body composition in overweight/obese adolescents, and iii) effects on cardiovascular parameters and autonomic cardiac modulation (ACM) of overweight/obese adolescents. Methods: The sample consisted of 33 overweight/obese adolescents aged 10 to 17 years who were evaluated for: i) Total and segmental body composition (lean, fat and bone mass); ii) Measurement of systolic blood pressure (SBP) and diastolic blood pressure (DBP) and resting heart rate (HR); iii) ACM; iv) Food frequency; And v) Practice of physical activity. MT training was 16 weeks, three times a week, for an hour and a half. The control group (CG) did not perform the training. This study presents the results of three studies, using the Shapiro-Wilk, Kolmogorov Smirnov, independent t test, repeated measures ANOVA with adjustments for confounding factors and effect size. SPSS Software was used and p-value <5%. Results: Comparing the initial moment with the recovery of a MT session, SBP reduced in boys after 20 min and 30 min, and in girls after 20 min. In the SBP there was a reduction in the girls shortly after the session and 10 min, and in both sexes shortly after the session and 10 min. There was no recovery of HR. After 16 weeks of MT training there was a significant difference in the group effect for the variables of body mass, body fat (BF), total fat mass (FM), arms FM, trunk fat and android fat. On the other hand, the total and leg lean mass (LM) presented a significant interaction effect, in which the MT group increased more compared to the CG. In the bone part there were no significant differences. After 16 weeks, the MT group significantly reduced heart rate in the interaction effect, when compared to CG. In addition, the MT group, in general, tended to improve ACM and reduce BF. Conclusion: It can be concluded that an MT session provided BP hypotensive effects. In addition to 16 weeks of the practice of MT significantly increase the total and leg LM, reduce HR, in addition to exhibiting a tendency to reduce BF in general, as well as improve ACM.
