Reabilitação funcional e barreiras para atividade física na COVID-longa: um ensaio clínico randomizado / Functional rehabilitation and barriers to physical activity after COVID-19: a randomized clinical trial

O estudo teve como objetivo analisar as barreiras percebidas à prática de atividade física durante um programa de treinamento multicomponente em adultos e idosos pós infecção por COVID-19. Realizou-se um ensaio clínico randomizado com 40 participantes (19 grupo controle e 21 grupo intervenção). Foram coletadas informações sociodemográficas, de saúde e de barreiras para a prática de atividade física, antes, 12 e 24 semanas após o início da intervenção. A medida das barreiras para a prática de atividade física foi obtida por meio de uma escala válida composta por 16 itens. As diferen-ças de barreiras entre os grupos e ao longo de tempo foi analisada a partir das Equações de Estimativa Generalizada, α = 0,05. As barreiras mais citadas pelos dois grupos na linha de base foram "Preguiça, cansaço ou desânimo" (71%), "Dores, lesões ou incapacidade" (38%) e "Falta de motivação" (48%). As análises principais indicaram que ambos os grupos tiveram redução na frequência da barreira "Pre-guiça, cansaço ou desânimo" na 12ª semana (p = 0,003), porém voltando aos valores iniciais na 24ª semana (p = 0,441). Já a barreira "Por causa da epidemia de coronavírus" foi reduzida na 12ª semana (p = 0,704) e ainda mais reduzida na 24ª semana (p = 0,158), comportamento também similar entre os grupos. Como principal conclusão, barreiras para atividade física podem ser reduzidas pela parti-cipação em programas de exercício supervisionado e recomendação para a prática de atividade física

The study aimed to analyze perceived barriers to physical activity during a multicomponent training pro-gram in adults and seniors post-COVID-19 infection. A randomized clinical trial was conducted with 40 participants (19 control group and 21 intervention group). Sociodemographic, health, and barriers to physical activity information were collected before, 12 and 24 weeks after the start of the intervention. The measure of barriers to physical activity was obtained through a valid scale composed of 16 items. Differences in barriers between groups and over time were analyzed using Generalized Estimating Equations, α = 0.05. The most frequently mentioned barriers at baseline by both groups were "Laziness, fatigue, or lack of enthusiasm" (71%), "Pain, injuries, or disability" (38%), and "Lack of motivation" (48%). The main analyses indicated that both groups had a reduction in the frequency of the barrier "Laziness, fatigue, or lack of enthusiasm" at week 12 (p = 0.003), but returned to initial values at week 24 (p = 0.441). The barrier "Because of the coronavirus epidemic" was reduced in week 12 (p = 0.704) and further reduced in week 24 (p = 0.158), with a similar pattern between groups. The key conclusion is that barriers to physical activity can be reduced through participation in supervised exercise programs and recommendations for physical activity

Effects of physical training on functional, clinical, morphological, behavioural and psychosocial outcomes in post-COVID-19 infection: COVID-19 and REhabilitation study (CORE-study)-a study protocol for a randomised controlled clinical trial.

BACKGROUND: The COVID-19 pandemic remains ongoing, with a significant number of survivors who have experienced moderate to severe clinical conditions and who have suffered losses of great magnitude, especially in functional capacity, triggering limitations to daily autonomy and quality of life. Among the possibilities of intervention for disease rehabilitation, physical exercise training stands out, which can benefit several health outcomes and favours the adoption of healthier behaviours. Therefore, the aim of the study will be to analyse the effects of physical training on the functional, clinical, morphological, behavioural and psychosocial status in adults and the elderly following COVID-19 infection. METHODS: A randomised controlled clinical trial is to be conducted in parallel, with the experimental group undergoing an intervention involving a multicomponent physical rehabilitation programme, carried out at the Sports Center in partnership with the Academic Hospital of the Federal University of Santa Catarina, in Florianópolis, Brazil. Participants will be adults and the elderly, of both sexes, in a post-COVID-19-infection state, who were hospitalised during the infection. The intervention will have a total duration of 24 weeks and will include a multicomponent physical training programme, which will have gradual progression in frequency, duration and intensity over time. Regarding the outcomes, before, at the 12th and after 24 weeks of intervention, functional (primary outcome = functional index of aerobic capacity), clinical, morphological, behavioural and psychosocial outcomes will be assessed. DISCUSSION: This study will contribute to a greater understanding of the safety, adherence and benefits of physical training in the rehabilitation of post-COVID-19 patients. The results of this study will be disseminated through presentations at congresses, workshops, peer-reviewed publications and local and international conferences, especially with a view to proposing a post-COVID-19 rehabilitation care protocol.
