Physical Capacity and Functional Abilities Improve in Young Adults with Intellectual Disabilities after Functional Training

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.

The Health Effects of 14 Weeks of Physical Activity in a Real-Life Setting for Adults with Intellectual Disabilities

Background

The life expectancy of individuals with intellectual disabilities (ID) is reduced compared to the general population, and one of the main contributors to earlier death is inactivity.

Aim

To investigate how 14 weeks of physical activity (PA) in a real-life setting affects cardiovascular fitness, body composition and bone health of adults with ID.

Methods

Adults with ID were recruited into a PA-group (N = 52) or a control group (CON, N = 14). The PA-group participated in 14 weeks of PA, and body composition, cardiovascular fitness and bone health were assessed before and after the intervention. Outcomes and Results. Cardiovascular fitness and body composition improved from pre to post within the PA-group: Heart rates (HR) during the last 30 seconds of two increments of a treadmill test, were reduced (3.2 km/h: -4.4 bpm, p < 0.05; 4.8 km/h: -7.5 bpm, p < 0.001) and fat mass was reduced (-1.02 kg, p < 0.05). A between-group difference in favour of the PA-group, were observed in whole body bone mineral density (BMD) (0.024 g/cm2, p < 0.05). Conclusions and Implications. Fourteen weeks of PA performed in a real-life setting increased cardiovascular fitness, reduced fat mass and improved BMD in the weight-bearing skeleton in the PA-group. Increased and regular PA seems to be a promising tool to promote physical health in adults with ID.

Anthropometric Indicators of the Cardiometabolic Risk, Muscle Strength, and Functional Capacity of Schoolchildren with Intellectual Disabilities during Lockdown in Chile

Lockdown due to the COVID-19 pandemic has negatively impacted the social, psychological, and physical well-being of the world population. In the case of people with intellectual disabilities, the impact of lockdown on their physical condition and functionality is not completely clear. This study aimed to determine the effects of COVID-19 lockdown on the anthropometric indicators of cardiometabolic risk, muscle strength, and functionality on schoolchildren with intellectual disabilities. The sample was composed of 132 students of both sexes (n = 74 pre-lockdown; n = 58 lockdown) belonging to two special education centers from the Metropolitan Region of Santiago, Chile. Our results showed significant reductions (p ≤ 0.05) in absolute and relative handgrip strength, as well as in functionality, when comparing pre-lockdown and lockdown measurements, with a greater loss in girls than boys. The design and implementation of physical exercise programs centered on strength training are necessary for the physical and functional reconditioning of this population. These programs need to be implemented in special education centers considering the general well-being, quality of life and work needs of people with intellectual disabilities.

Review on the Formulation, Existing Problems, and Practical Effects of Fitness Exercise Prescriptions for People With Intellectual Disabilities

Compared with normal people, patients with intellectual disability have poor cardiopulmonary and muscle fitness levels, and their daily physical activity generally cannot reach the "guideline-recommended amount," which increases the risk of obesity and cardiovascular disease in this group. From the perspective of six elements of exercise prescription (frequency, intensity, time, form of exercise, amount of exercise, and progressive rate), this paper systematically reviews the current situation of the formulation and implementation of exercise prescription for patients with intellectual disabilities. The results show that the design idea of aerobic fitness exercise prescription for patients with intellectual impairment follows the six-element 5paradigm, but the insufficient recommended amount of each element is a common problem. In the design of muscle fitness exercise prescription, due to the differences of different exercise forms, the description of the six elements is very inconsistent. Although most prescription execution effects show that it is beneficial to improve cardiopulmonary and muscle fitness, there is a great debate on whether it is beneficial to improve body composition. People with intellectual disabilities are highly heterogeneous groups. In the initial stage of exercise intervention, the elements of exercise prescription need to be adjusted individually to obtain sustainable positive benefits.

A Scoping Review of Recreational Sport Programs for Disabled Emerging Adults

Purpose: Recreational sport programs are a critical but overlooked pathway for enhancing social participation of emerging adults with disabilities. Specifically, the experiences of recreational sport program members are important for continued community engagement among emerging adults. To address this gap, this scoping review examined the published studies on recreational sport programs for emerging adults with disabilities with the aim of providing future directions for practice (e.g., program instruction) and research (e.g., measurement). Method: Using the PRISMA-SR guidelines, six electronic databases were searched using key terms of disability, age, and recreational sport; findings were extracted and summarized according to the quality parasport participation framework (autonomy, belonging, challenge, engagement, mastery, meaning) and other outcome measures of the included studies. An online 26-item survey was sent to the included studies' authors to further explore the programs' conditions. Results: There were 16,818 records screened with seven articles included. Studies indicate positive outcomes for emerging adults with disabilities immediately following participation in sport programs (e.g., improved self-esteem, autonomy, friendship skills, and balance). No longitudinal studies have been conducted on sustained participation in sport programs or transfer effects of participation. Conclusion: Despite the limited literature, this scoping review provides the foundation for the development of evidence-informed, participant-driven sport programs for emerging adults with disabilities. This study highlights areas for further development for both researches (e.g., evaluating and reporting quality) and practice (e.g., program evaluation).

Effects of exercise on the physical fitness level of adults with intellectual disability: a systematic review

Purpose: To systematically review the existing scientific evidence regarding the effects of physical exercise on the fitness level of people with intellectual disabilities.Methods: Following the checklist of the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols, the PubMed, CINAHL, SPORTDiscus, and Scopus databases were searched using specific keywords up to January 2018. The methodological quality of the studies found was rated by the means of specific scales according to their specific design.Results: A total of 44 studies were selected. The majority of the included studies were randomized controlled trials (n = 17), followed by non-controlled studies (n = 11), non-randomized controlled trials (n = 10), and comparative studies (n = 6). Aerobic, strengthening, and combined exercise programs were the most frequently proposed interventions. Exercise showed to have significant effects on the cardiorespiratory and muscular fitness. Not all the selected studies reported improvements in parameters related to body composition.Conclusions: There is sufficient scientific evidence for the beneficial effects of exercise on the cardiovascular and muscular fitness of adults with mild/moderate ID. There is a need for more studies focused on the impact of physical exercise on the body composition of this population, and those that aim at identifying the impact of alternative interventions.IMPLICATIONS FOR REHABILITATIONThere is a need for basic guidelines that can help rehabilitation professionals to prescribe exercise for maintaining and improving physical fitness in the adults with intellectual disabilities.In adults with intellectual disabilities, aerobic exercise has beneficial effects on cardiovascular and muscular fitness, flexibility, and range of motion.No firm conclusion can be made regarding the effects of aerobic, muscular, and combined training programs on the body composition of adults with intellectual disabilities.Rehabilitation professionals should be aware that scientific evidence regarding the prescription of alternative exercise protocols in adults with intellectual disabilities (i.e. dancing, water-based exercise, animal therapy, etc) is scarce.

Physical Activity Research in Intellectual Disability: A Scoping Review Using the Behavioral Epidemiological Framework

Through a scoping review, the current state of physical activity research in people with intellectual disability was examined. A search of publications between 2000 and 2014 retrieved 362 articles that met inclusion criteria. Eligible studies were coded according to the Behavioral Epidemiological Framework. Of the articles identified, 48% examined associations between physical activity and health outcomes, 9% developed or tested methodology to measure physical activity, 34% examined factors that influence physical activity, 8% evaluated interventions to change physical activity, and 1% examined the dissemination of physical activity/health promotion programming. The categories with lower proportions of studies represent the need for greater population-specific research in physical activity measurement, interventional designs, and translational programs.

School-Based Work Capacity Evaluation in Young People With Intellectual Disabilities: 2 Case Reports

PURPOSE

These case reports examine the application of a work capacity/work-hardening model to increase work capacity in young people with disabilities.

KEY POINTS

Examination, evaluation, interventions, and outcomes are described for 2 teenagers with intellectual disability. This approach is novel in that it uses functional capacity evaluation concepts used in ergonomic/occupational health contexts and applies them to youth with disabilities in educational settings.

CONCLUSION

These concepts expand the scope of practice for physical therapists in school settings and potentially increase work opportunities for youth with disabilities.

A community-based aquatic exercise program to improve endurance and mobility in adults with mild to moderate intellectual disability

The purpose of this study was to investigate the impact of a community-based aquatic exercise program on physical performance among adults with mild to moderate intellectual disability (ID). Twenty-two community-dwelling adults with mild to moderate ID volunteered to participate in this study. Participants completed an 8-week aquatic exercise program (2 days/wk, 1 hr/session). Measures of physical performance, which were assessed prior to and following the completion of the aquatic exercise program, included the timed-up-and-go test, 6-min walk test, 30-sec chair stand test, 10-m timed walk test, hand grip strength, and the static plank test. When comparing participants’ measures of physical performance prior to and following the 8-week aquatic exercise program, improvements were seen in all measures, but the change in scores for the 6-min walk test, 30-sec chair stand test, and the static plank test achieved statistical significance (P<0.05). An 8-week group aquatic exercise program for adults with ID may promote improvements in endurance and balance/mobility.
