RESUMO

BACKGROUND: The main objective of this study was to evaluate gait parameters in people with intellectual disability (ID) and without intellectual disability (WID) in two different walking conditions [single task vs. dual task (DT)]. A secondary aim was to evaluate the dual-task cost (DTC) that the DT causes in each group. METHODS: A total of 119 participants joined in this study: 56 ID (30 men) and 63 WID (30 men). The OptoGait system was used to assess gait. In addition, Witty photocells were added to assess gait under the DT condition. RESULTS: Single support time was lower for participants with ID (P < 0.01), while double support time was higher (P < 0.05). All coefficients of variation for gait parameters were higher in participants with ID. Additionally, changes in gait were observed in both groups during the DT condition compared with the single-task condition. These changes were larger for participants with ID in step length, double support time and gait speed (P < 0.001), resulting in a higher DTC in these variables in the ID group (P < 0.01). CONCLUSIONS: Both groups reduced gait performance in the DT condition. However, greater gait variability occurred in the ID group. In addition, DTC was higher for the ID group in all variables analysed. Therefore, people with ID show worse gait performance during a DT than people WID.

RESUMO

BACKGROUND: The objective of this study was to evaluate the effectiveness of a 14-week resistance training programme implemented with high levels of effort to improve physical fitness in people with intellectual disabilities (IDs) living in group homes. METHODS: Fifty-two individuals with mild to moderate IDs participated in the experimental (n = 27; 15 men) or control groups (n = 25; 14 men). Participants performed 2 familiarisation sessions, 1 pretest, 42 training sessions (14 weeks × 3 sessions; only the experimental group) and 1 posttest. The testing sessions comprised the evaluation of body composition, static balance and muscle strength. The training sessions included four blocks: (1) dynamic bodyweight exercises, (2) dynamic exercises performed against external loads, (3) ballistic exercises and (4) static exercises. RESULTS: The main findings revealed that all variables related to body composition and muscle strength improved more after the intervention period in the experimental group than the control group, whereas the improvements in static balance for the experimental groups were lower than for the remaining variables used as markers of physical fitness. CONCLUSIONS: These findings highlight the importance of prescribing specific moderate-intensity to high-intensity resistance training programmes to improve body composition and muscle strength for people with IDs living in group homes.
