Resumo(s)
As doenças cardiovasculares (DCV) são uma das principais causas de morte em pessoas
com dificuldade intelectual e de desenvolvimento (DID). Fatores de risco tradicionais e
emergentes estão associados ao desenvolvimento de DCV. A atividade física é
considerada uma estratégia universal para a redução do risco de DCV. No entanto, o
confinamento domiciliário apenas permite aplicar intervenções domiciliárias e até ao
momento, a eficácia deste tipo de intervenção na redução de fatores de risco em pessoas
com DID permanece esclarecer.
O objetivo do estudo foi comparar contextos de exercício, domiciliário vs presencial,
durante 8 semanas de dois regimes de treino aeróbio supervisionados na rigidez arterial e
na aptidão cardiorrespiratória em adultos com DID. A intervenção incluí-o 17 adultos com
DID que foram divididos em dois regimes: treino intervalado em sprints (SIT) e treino
contínuo (CAET). Os treinos foram realizados 3 vezes por semana durante 60 minutos. A
intervenção presencial melhorou a aptidão cardiorrespiratória e ambos os contextos
resultaram em melhorias semelhantes na rigidez arterial.
Concluindo, uma intervenção domiciliária consegue minimizar alguns efeitos fisiológicos
deletérios de um confinamento obrigatório em vários fatores de risco, no entanto não
corresponde aos benefícios de uma intervenção presencial, independentemente do regime
de treino aeróbio.
Cardiovascular diseases (CVD) are a leading cause of death in people with intellectual and developmental disability (IDD). Traditional and emergent risk factors such as cardiorespiratory fitness and arterial stiffness are associated with the development of CVD. Physical activity has been appointed as an essential universal strategy for reducing the risk of CVD. However, during the mandatory lockdown home-based interventions are the only alternative to reduce risk factors, and the efficacy of these interventions needs to be confirmed in people with IDD. The present study aims to compare home vs gym-based delivery exercise modes of two 8- week supervised aerobic training regimes on cardiorespiratory fitness and arterial stiffness in adults with IDD. The intervention included 17 adults with IDD and participants were divided into two regimes: sprint interval training (SIT) and continuous aerobic exercise training (CAET). Training for both regimes was performed 3 times a week for 60 minutes. Only the gym-based intervention improved cardiorespiratory fitness and both contexts had similar results on arterial stiffness. In conclusion, a home-based intervention may minimize the deleterious physiological effects of a mandatory lockdown on several risk factors but does not match the benefits of a gym-based intervention, regardless of exercise regime
