Effects of exercise training on obesity-related parameters in people with intellectual disabilities: systematic review and meta-analysis

Effects of combined training in individual with Intellectual and Developmental Disabilities: a systematic review and meta-analysis of randomized controlled trials

PURPOSE OF THE ARTICLE

This study aims to evaluate the literature, peer-reviewed clinical trials investigating the effects of combined exercise interventions on individuals with Intellectual and Developmental Disabilities.

MATERIALS AND METHODS

Various databases, using various descriptors and Boolean operators were utilized.

RESULTS

Eight studies meet the eligibility criteria. Regarding the anthropometric measures/body composition variable, the meta-analysis revealed that combined physical exercise did not have a significant effect (standard mean difference (SMD) = -0.16; 95% CI, -0.34 to 0.03; Z = 1.68; p = 0.09). For the lipid profile variable, the combined exercise interventions did not show a significant effect (SMD = -0.07; 95% CI, -0.43 to 0.29; Z = 0.38; p = 0.71). Combined exercise training had a significant effect on increasing functional capacity (SMD = 0.28; 95% CI, 0.01 to 0.54; Z = 2.03; p = 0.04), cardiorespiratory function (SMD = 0.80; 95% CI, 0.34 to 1.26; Z = 3.41; p ≤ 0.001), and strength (SMD = 0.77; 95% CI, 0.45 to 1.08; Z = 4.78; p ≤ 0.001).

CONCLUSIONS

Participants from the intervention group that took part in combined exercise training showed a higher probability of improving their functional, cardiorespiratory, and strength capacity compared to the control group.

Impact of Resistance Training on Body Composition and Physical Function in Individuals with Down Syndrome: A Meta-Analysis

Objectives: Down syndrome (DS) is associated with challenges like increased fat mass and reduced muscle tone. This study aims to analyze the impact of resistance training on improving muscle strength and physical function in individuals with DS. Methods: We conducted a comprehensive search of PubMed, Scopus, Google Scholar, Cochrane Library, and China National Knowledge Infrastructure for studies published up to August 2023. Standardized mean differences and 95% confidence intervals were used to evaluate the efficacy of resistance training. Results: Eight randomized controlled trials (RCTs), including 127 participants with DS, met the inclusion criteria. Resistance training significantly improved muscle strength in the knee extensors (SMD: 1.009, 95% CI: 0.505-1.513), knee flexors (SMD: 1.133, 95% CI: 0.106 to 2.16), and upper limbs (SMD: 0.748, 95% CI: 0.152-1.343). The SMD for upper limb function was 0.385 (95% CI: 0.004-0.765), showing a small improvement. For walking ability, the SMD was 0.259 (95% CI: -0.171-0.690), and for stair climbing ability, the SMD was 0.257 (95% CI: -0.189-0.703), both indicating no significant changes. Improvements in upper limb physical function were significant, but no notable improvements were seen in lower limb functions. Conclusions: Resistance training for more than four weeks enhances muscle strength in individuals with DS, with greater gains seen in younger participants. While improvements were noted in upper limb physical function, lower limb function remained largely unchanged. These findings suggest that resistance training is a valuable exercise for improving muscle strength and physical function in individuals with DS.

The impact of a virtual wellness course for adults with intellectual and developmental disabilities in the third year of COVID-19

The current study examines how a virtual wellness intervention may improve health outcomes in adults with intellectual and developmental disabilities. Thirty-six adults with intellectual and developmental disabilities participated in the wellness intervention. Outcome measures related to satisfaction, mental health, wellbeing, health behaviours and overall health were completed at three time points (pre, post and follow-up). Participants reported high levels of satisfaction and had significant improvements in outcomes related to mental health and wellbeing. Changes in sleep, sedentary behaviour and overall health were not reported, though qualitative evidence suggests that some changes were implemented. The study provides evidence to support the use of virtual interventions to address health concerns in individuals with intellectual and developmental disabilities.

Effects of physical activity and exercise-based interventions in young adults with autism spectrum disorder: A systematic review

LAY ABSTRACT

Young adults with autism spectrum disorder over 18 years of age are an underserved population, and there is presently limited evidence examining the effects of physical activity programs in this population. Our review synthesizes the evidence to date from studies that have assessed the effects of physical activity/exercise programs in young adults with autism spectrum disorder between 19 and 30 years. We reviewed 22 studies that included a total of 763 young adults with autism spectrum disorder. There is the strongest evidence for improvements in physical fitness, followed by motor skills, psychological function, and quality of life following physical activity interventions in young adults with autism spectrum disorder. Specifically, aerobic and resistance training as well as programs focused on movement skill and sport-specific training lead to improved physical fitness and movement performance. Holistic interventions focusing on physical activity, dietary changes, and lifestyle modifications lead to improvements in body composition and quality of life of young adults with autism spectrum disorder. There is presently limited evidence to support the use of exercise/activity programs to improve physical activity levels and core autism symptoms in young adults with autism spectrum disorder. Based on our review results, we also provide practical recommendations for clinicians working with young adults with autism spectrum disorder.

Impact of Physical Activity on Autonomy and Quality of Life in Individuals with Down Syndrome: A Systematic Review

Down syndrome (DS) is the most common genetic alteration in humans, resulting from the trisomy of chromosome 21. Individuals with DS are characterized by physical traits and limitations related to intellectual functioning and the development of motor skills. People with DS tend to have lower levels of physical activity (PA) than the general population, despite its benefits for health and quality of life, which could be caused by barriers such as the lack of adapted programs or knowledge on how to adapt them. Therefore, this systematic review aimed to examine the impact of physical activity or sports programs on autonomy and quality of life in individuals with DS. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed to search four databases (Scopus, Web of Science, PubMed, and SportDiscus), adhering to the population, intervention, comparison, and outcome strategy. A total of 13 studies were selected that followed different training programs (combined training, adapted football, technology-based, pulmonary training, gymnastics and dance, water-based, and whole body vibration). Most of the interventions provided benefits for autonomy or quality of life (physical, psychological, cognitive, emotional, and social) in people with DS. In conclusion, the benefits of physical activity and sports programs adapted to people with DS are positive.
