RESUMEN

BACKGROUND: To determine the feasibility and effect of high-intensity interval training (HIIT) in individuals with Parkinson's and their effect on symptom modification and progression. METHODS: We conducted this systematic review following the Preferred Reporting Items for systematic review and meta-analysis (PRISMA). All studies were searched in seven databases: MEDLINE (PubMed), Cochrane Central Register of Controlled Trials, Web of Science, EMBASE, SPORTDiscus, Virtual Health Library (VHL) and SCOPUS in September 2020 and updated in June 2023. The risk of bias was assessed by the Cochrane Collaboration tool and Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool. We used standardized mean difference (SMD) with a 95% confidence interval (CI) and random effects models, as well as the non-parametric Cochran's Q test and I2 inconsistency test to assess heterogeneity. RESULTS: A total of 15 randomized clinical trials with 654 participants (mean age, 65.4 years). The majority of studies included high intensity training interventions versus moderate intensity, usual care, or control group. The meta-analysis comparing high-intensity exercise versus control group showed an improvement in the disease severity (MD = -4.80 [95%CI, -6.38; -3.21 high evidence certainty); maximum oxygen consumption (MD = 1.81 [95%CI, 0.36; 3.27] very low evidence certainty) and quality of life (MD = -0.54 [95%CI, -0.94; -0.13] moderate evidence certainty). The results showed that high-intensity exercise compared with moderate intensity exercise group showed a improve motor function and functional mobility measured by the TUG test (MD = -0.38 [95%CI, -0.91; 0.16] moderate evidence certainty) with moderate heterogeneity between studies. CONCLUSION: High-intensity exercise performed in both continuous and interval modes when compared with control groups may provide motor function benefits for individuals with Parkinson's disease. HIIT may be feasible, but the intensity of the exercise may influence individuals with Parkinson's disease. However, there was a lack of evidence comparing high intensity and moderate intensity for this population, as the results showed heterogeneity.

RESUMEN

Introdução: Um dos grandes benefícios que o exercício físico promove no envelhecimento é a preservação das capacidades funcionais. O circuito de treinamento visa melhorar controle corporal, equilíbrio muscular, diminuindo a incidência de lesões e aumentando a eficiência dos movimentos. O objetivo deste trabalho é apresentar as evidências cientificas disponíveis na literatura sobre a relação entre a aplicação do circuito de treinamento e capacidades físicas em idosos. Métodos: Os bancos de dados Bireme, Web of Science, PubMed e Science Direct foram utilizados para a seleção dos artigos publicados nos últimos cinco anos. Resultados: Apenas quatro estudos foram selecionados para a realização da revisão sistemática, preenchendo os critérios de inclusão e exclusão. Conclusão: Diante das evidências existentes em relação à intervenção baseada em circuitos de treinamento, foi observado melhora no funcionamento físico e fisiológico dos idosos.

Introduction: One of the great benefits that physical activity promotes in ageing is the preservation of functional capabilities. The training circuit aims to improve body control, muscle balance, reducing the incidence of injuries and increasing the efficiency of movements. The objective of this work is to present the scientific evidence available in the literature on the relationship between the application of the training circuit and physical capacities in older adults. Methods: the database Bireme, Web of Science, PubMed and Science Direct were used to identify the articles published in the last five years. Results: Only four studies were included to perform the systematic review, fulfilling the inclusion and exclusion criteria. Conclusion: Regular physical exercise can reduce functional declines by improving physical abilities in older adults. Given the existing evidence regarding circuit-based intervention, the training circuit improves physical and physiological functioning of older adults.
