RESUMO
PURPOSE: to assess the effects of supervised and unsupervised gamified exercise programs on physical activity level, sedentary behavior and quality of life in patients with non-communicable chronic diseases. MATERIALS AND METHODS: Six database were searched. Methodological quality of included studies, the quality of reporting interventions and the quality of the applications were assessed using the PEDro, TIDieR and MARS, respectively. RESULTS: Nine studies were included (n = 974; 60.2 ± 5.7 years). Three of them enrolled individuals with cancer, one with stroke, one with multiple sclerosis, one with COPD, two with Diabetes Mellitus, and one with knee and hip osteoarthritis. Gamification was performed via a smartphone application in three studies (MARS = 13.4 ± 9.75pts, ranging from 10.9 to 16.9pts). The intervention was supervised in six studies. The PEDro and TIDIeR scores were 5.5 ± 1.3 (ranging 0-8pts) and 16.11 ± 3.14 (ranging 10-20pts), respectively. Supervised gamified interventions increased the level of physical activity compared to usual supervised exercises. Quality of life was similar between groups. Unsupervised interventions were similar for all outcomes evaluated. CONCLUSIONS: Supervised gamified exercise programs seem to increase the level of physical activity compared to usual exercises in patients with chronic diseases. However, studies with better methodological qualities and subgroup analyzes are needed.
RESUMO
OBJECTIVES: To compare obtained and predicted inspiratory and expiratory muscle strength between frail, pre-frail, and non-frail older people; to examine the association between inspiratory and expiratory muscle strength and frailty in older people; and to determine cut-off points for inspiratory and expiratory muscle strength for discriminating frailty in older people. METHODS: A cross-sectional study was conducted with 379 community-dwelling older adults. Frailty was assessed using Fried's phenotype, while inspiratory and expiratory muscle strength were measured with maximum inspiratory and maximum expiratory pressures. Inferential analyses were performed using paired Student t-tests, one-way analysis of variance (ANOVA) tests, and a multinomial logistic regression model. ROC curves were constructed to establish cut-off points of maximum inspiratory and expiratory pressures for discriminating frailty and pre-frailty. RESULTS: Frail and pre-frail participants presented significantly lower mean inspiratory and expiratory pressures compared to non-frail participants; values were significantly lower than predicted. Inspiratory and expiratory muscle strength were inversely associated with frailty and pre-frailty. Cut-off points ≥-50cmH2O and ≤60cmH2O for maximum inspiratory and expiratory pressures, respectively, were established as optimal discriminators of frailty. The cut-off point ≤65cmH2O for maximum expiratory pressure was established as a discriminant for the presence of pre-frailty. CONCLUSIONS: Inspiratory and expiratory muscle strength were lower in frail than in pre-frail older adults, and lower in pre-frail than in non-frail peers. Frailty and pre-frailty were inversely associated with inspiratory and expiratory muscle strength. Cut-off points for inspiratory and expiratory muscle strength may be useful in clinical practice for discriminating frailty and pre-frailty in older adults.
