Introdução: Na Diabetes Mellitus Tipo 2 (DMT2) existe uma diminuição da modulação autonómica cardíaca e uma redução da variabilidade da frequência cardíaca (VFC). Objetivo: Analisar a efetividade do treino aeróbio na VFC em pacientes com DMT2. Metodologia: Foi realizada uma pesquisa eletrónica nas bases de dados Pubmed, Physiotherapy Evidence Database (PEDro), Web of Science, MEDLINE e SPORTDiscus. Os critérios de elegibilidade definidos foram: 1) estudos experimentais do tipo randomizado controlado; 2) estudos que avaliam o efeito do treino aeróbio na VFC em pacientes com DMT2; 3) estudos em língua inglesa, portuguesa, italiana ou espanhola. Resultados: Foram incluídos 5 artigos para análise que cumpriram os critérios de seleção. Nestes artigos participaram um total de 197 indivíduos com uma idade média de 58,7 anos. Dois estudos efetuaram o treino aeróbio contínuo e 3 estudos efetuaram treino intervalado de alta intensidade (HIIT). A duração dos protocolos variou de 12 semanas a 12 meses. Quatro dos cinco estudos melhoram os valores da VFC após o treino e, apenas um, não apresentou aumento significativo neste parâmetro. Conclusão: O treino aeróbio em pacientes com DMT2 parece induzir um aumento da VFC. O HIIT supervisionado parece ser mais vantajoso, assim como uma maior frequência de treino semanal.
Introduction: In Diabetes Mellitus Type 2 (DMT2) there is a decrease in cardiac autonomic modulation and a reduction in heart rate variability (HRV). Objective: Analyze the effectiveness of aerobic training in HRV in patients with DMT2. Methodology: An electronic search was carried out in the Pubmed, Physiotherapy Evidence Database (PEDro), Web of Science, MEDLINE and SPORTDiscus databases. The eligibility criteria defined were: 1) experimental studies of the randomized controlled type; 2) studies evaluating the effect of aerobic training on HRV in patients with DMT2; 3) studies in English, Portuguese, Italian or Spanish. Results: Five articles were included for analysis that met the selection criteria. A total of 197 individuals with an average age of 58.7 years participated in these articles. Two studies performed continuous aerobic training and 3 studies performed high intensity interval training (HIIT). The duration of the protocols ranged from 12 weeks to 12 months. Four of the five studies improved HRV values after training and only one did not show a significant increase in this parameter. Conclusion: Aerobic training in patients with DMT2 seems to induce an increase in HRV. Supervised HIIT seems to be more advantageous, as well as a greater frequency of weekly training.
