RESUMO

ABSTRACT Objective: Substance misuse can lead to several consequences for physical and mental health. Physical exercise is an important ally to pharmacological and psychotherapeutic treatment for substance use. However, the literature is still scarce regarding long-term interventions. Thus, this study aims to describe the acceptability and effects of combined physical training intervention (aerobic and strength). Methods: This study comprises an n-of-1 clinical trial that was performed with a 64-year-old male individual with alcohol use disorder. The treatment lasted 12 weeks and evaluated the association of multidisciplinary interventions on quality of life, depressive symptoms, cognitive impairment, and anxiety. Results: The participant improved general quality of life (12.5%), no alterations were found for depressive symptoms, there was an improvement in cognition (20%), as well a reduction in the trait (16.2%) and state (14.7%) anxiety symptoms of the participant. Conclusions: These findings allude to the importance of non-drug therapeutic resources such as structured physical exercise, associated with other offers in the treatment of alcohol use disorder.

RESUMO Objetivo: O uso de substâncias psicoativas pode levar a diversas consequências à saúde física e mental. O exercício físico é um importante aliado ao tratamento farmacológico e psicoterápico para o uso de substâncias. No entanto, a literatura ainda é escassa em relação às intervenções de longa duração. Dessa forma, este estudo objetiva descrever a aceitabilidade e os efeitos de uma intervenção de treinamento físico combinado (aeróbico e força). Métodos: Este estudo compreende um n-of-1 clinical trial que foi realizado com um indivíduo do sexo masculino, de 64 anos de idade, com transtorno por uso de álcool. O tratamento teve a duração de 12 semanas e avaliou a associação de intervenções multiprofissionais sobre a qualidade de vida, sintomas depressivos, comprometimento cognitivo e ansiedade. Resultados: O participante melhorou a qualidade de vida geral (12,5%), não foram encontradas alterações para sintomas depressivos, houve melhora na cognição (20%), bem como redução nos sintomas de ansiedade traço (16,2%) e estado (14,7%) do participante. Conclusões: Esses achados aludem à importância de recursos terapêuticos não medicamentosos como o exercício físico estruturado, associados às demais ofertas no tratamento para o transtorno por uso de álcool.

RESUMO

The aim of this study was to evaluate the acute effect of aerobic (AER) and eccentric (ECC) exercise on glucose variability, correlating it with circulating markers of inflammation and oxidative stress in healthy subjects. Sixteen healthy subjects (32 ± 12 years old) wore a continuous glucose monitoring system for three days. Participants randomly performed single AER and ECC exercise sessions. Glucose variability was evaluated by glucose variance (VAR), glucose coefficient of variation (CV%) and glucose standard deviation (SD). Blood samples were collected to evaluate inflammatory and oxidative stress markers. When compared with the pre-exercise period of 0-6 h, all the indices of glucose variability presented comparable reductions 12-18 h after both exercises (∆AER: VAR= 151.5, ∆CV% = 0.55 and ∆SD = 3.1 and ECC: ∆VAR = 221.2 , ∆CV% = 3.7 and ∆SD = 6.5). Increased interleukin-6 (IL-6) levels after AER (68.5%) and ECC (30.8%) (P<0.001) were observed, with no differences between sessions (P = 0.459). Uric acid levels were increased after exercise sessions (3% in AER and 4% in ECC, P = 0.001). In conclusion, both AER and ECC exercise sessions reduced glucose variability in healthy individuals. Inflammatory cytokines, such as IL-6, and stress oxidative markers might play a role in underlying mechanisms modulating the glucose variability responses to exercise (clinicalTrials.gov NCT02262208).
