Barriers associated with exercise and community access for individuals with stroke

Increasing participation in physical activity among people with stroke continues to be a major challenge for healthcare professionals. We administered a survey to a group of 83 adults with unilateral stroke (mean age = 54.2 yr) to determine their perceived barriers to exercise. The five most common barriers in rank order were (1) cost of the program (61%), (2) lack of awareness of a fitness center in the area (57%), (3) no means of transportation to a fitness center (57%), (4) no knowledge of how to exercise (46%), and (5) no knowledge of where to exercise (44%). The least common barriers were (1) lack of interest (16%), (2) lack of time (11%), and (3) concern that exercise would worsen their condition (1%). People with stroke reported several barriers that prevented or reduced their participation in exercise. Healthcare professionals must identify and remove these barriers to promote greater participation in exercise among people with stroke.

Overweight Prevalence in Persons With Down Syndrome

Prevalence of overweight among the general population has been reported to be 33% for males and 36% for females. We undertook this study to establish overweight prevalence data in a cohort with Down syndrome and to stratify the incidence of overweight by living arrangement. We measured Body Mass Index (BMI) in 283 persons with Down syndrome and found a higher prevalence of overweight in this group compared to the general population. Individuals with Down syndrome living in a family setting had a higher incidence of overweight than did those living in a group home setting. Overweight prevalence among persons with Down syndrome should be considered a major public health concern that warrants further attention from researchers, practitioners, family members, and individuals with Down syndrome.

Obesity and obesity-related secondary conditions in adolescents with intellectual/developmental disabilities

BACKGROUND To explore the prevalence of obesity and related secondary conditions associated with obesity in adolescents with intellectual/developmental disabilities (IDD). METHODS In total, 461 parents of adolescents with IDD (M = 14.9 year, SD = 1.9) across 49 US states completed a web-based survey containing questions related to their childs health status, including body weight and existing health conditions. Results were compared with published data for youth without disabilities. RESULTS Adolescents with autism and Down syndrome were two to three times more likely to be obese than adolescents in the general population. Secondary health conditions were higher in obese adolescents with IDD compared with healthy weight adolescents with IDD including high blood pressure, high blood cholesterol, diabetes, depression, fatigue, liver or gallbladder problems, low self-esteem, preoccupation with weight, early maturation and pressure sores. CONCLUSION Obesity is as much of a health problem in youth with IDD as it is among youth without disabilities and, in certain disability groups, is a significantly greater health problem. Obese youth with IDD have a high number of obesity-related secondary conditions predisposing them to greater health problems as they transition into adulthood. Federal and local initiatives to reduce obesity among youth in the general population must recognise the need for interventions that are also relevant (i.e. accessible and effective) for youth with IDD.

Promotion of Physical Fitness and Prevention of Secondary Conditions for Children With Cerebral Palsy: Section on Pediatrics Research Summit Proceedings

Inadequate physical fitness is a major problem affecting the function and health of children with cerebral palsy (CP). Lack of optimal physical activity may contribute to the development of secondary conditions associated with CP such as chronic pain, fatigue, and osteoporosis. The purpose of this article is to highlight the content and recommendations of a Pediatrics Research Summit developed to foster collaborative research in this area. Two components of physical fitness—muscle strength and cardiorespiratory fitness—were emphasized. Although there is evidence to support the use of physical fitness interventions, there are many gaps in our current knowledge. Additional research of higher quality and rigor is needed in order to make definitive recommendations regarding the mode, intensity, frequency, and duration of exercise. Outcome measurements have focused on the body functions and structures level of the International Classification of Functioning, Disability and Health (ICF), and much less is known about effects at the activities and participation levels. Additionally, the influence of nutritional and growth factors on physical fitness has not been studied in this population, in which poor growth and skeletal fragility have been identified as serious health issues. Current intervention protocols and outcome measurements were critically evaluated, and recommendations were made for future research.

Research on physical activity and disability: an emerging national priority.

Despite the voluminous amount of research that has been published in the field of exercise science over the past three decades, there remains a paucity of information on the activity patterns and physiological responses to exercise in persons with disabilities. In an era when physical activity has grown to new heights in terms of its importance in promoting health and preventing disease, many questions pertaining to how it affects the lives of individuals with physical disabilities remain unanswered. The purpose of this paper is to review the prevalence of disability in the United States and to present recommendations for future research on physical activity and disability. A related objective of this paper is to encourage exercise scientists to undertake research on this increasingly significant group of American citizens.

Improvements in physical fitness in adults with Down syndrome.

The effectiveness of an exercise training program for 52 adults with Down syndrome (M age = 39.4 years) was evaluated. The training program consisted of cardiovascular (30 minutes) and strength exercise (15 minutes) for 12 weeks, 3 days a week for 45-minutes per session. Compared to control subjects, the training group improved significantly in cardiovascular fitness and muscular strength and endurance and had a slight but significant reduction in body weight. Greater effort must be made to promote increases in physical activity participation among persons with Down syndrome and developmental disabilities in order to reduce the potential health risks associated with low fitness and sedentary behavior.

Attitudinal and Psychosocial Outcomes of a Fitness and Health Education Program on Adults With Down Syndrome

Attitudinal and psychosocial outcomes of a fitness and health education program for adults with Down syndrome were examined. Participants were 53 adults with Down syndrome ages 30 years and older (29 females, 24 males, M age = 39.72 years) who were randomized into a training (n = 32) or control group (n = 21). The training group participated in a 12-week, 3 days per week, exercise and health education program. Outcome measures included attitudes towards exercise (cognitive-emotional barriers, outcomes expectations, and performance self-efficacy) and psychosocial well-being (community integration, depression, and life satisfaction). Compared to controls, the training group showed significant changes in attitudes towards exercise, including increased exercise self-efficacy, more positive expected outcomes, fewer cognitive-emotional barriers, improved life satisfaction, and marginally lower depression.

Health Promotion for People with Physical, Cognitive, and Sensory Disabilities: An Emerging National Priority.

Despite the growth in health promotion programs for able-bodied people, very little effort has been devoted to developing programs for people with physical and cognitive disabilities. Programs for people with disabilities must be developed with full recognition of limitations caused by both the primary and secondary disability.

Physical activity programs and behavior counseling in older adult populations

Physical activity offers one of the greatest opportunities for people to extend years of active independent life and reduce functional limitations. The purpose of this paper is to identify key practices for promoting physical activity in older adults, with a focus on older adults with chronic disease or low fitness and those with low levels of physical activity. Key practices identified in promotion activity in older adults include: 1) A multidimensional activity program that includes endurance, strength, balance, and flexibility training is optimal for health and functional benefits; 2) Principles of behavior change, including: social support, self-efficacy, active choices, health contracts, assurances of safety, and positive reinforcement enhance adherence; 3) Management of risk by beginning at low intensity but gradually increasing to moderate physical activity, which has a better risk-to-benefit ratio and should be the goal for older adults; 4) An emergency procedure plan is prudent for community based programs; and 5) Monitoring aerobic intensity is important for progression and for motivation. Selected content review of physical activity programming from major organizations and institutions are provided. Regular participation in physical activity is one of the most effective ways for older adults, including those with disabilities, to help prevent chronic disease, promote independence, and increase quality of life in old age.

Prediction of maximal heart rate in individuals with mental retardation.

PURPOSE It is well known that individuals with mental retardation (MR), especially those with Down syndrome (DS), have low maximal heart rates (MHR). We evaluated the ability to predict MHR in individuals with MR and DS in comparison with persons without MR. METHODS Subjects completed a maximal exercise test on the treadmill with metabolic and HR measurements. Stepwise multiple regression was used to develop prediction equations for subjects with MR (N = 276; 97 with DS) and without (N = 296) MR, ranging in age from 9-46 yr. RESULTS Subjects with MR exhibited significantly lower MHR (177 vs 185 beats.min(-1)) and VO2peak (33.8 vs 35.6 mL.kg-1.min(-1)). In subjects with MR, age was a poor predictor of MHR, Y = 189 - 0.59 (age) (R = 0.30, SEE = 13.8 beats.min-1; P < 0.01), but age was a better predictor for subjects without MR, Y = 205 - 0.64 (age) (R = 0.52, SEE = 9.9 beats.min(-1); P < 0.01). A large sample Z test indicated that these regression coefficients were significantly different (P < 0.01). However, adding DS to the regression improved the prediction for subjects with MR, Y = 210 - (0.56 age) - (15.5 DS) (R = 0.57; SEE = 11.8 beats.min(-1), P < 0.01). CONCLUSION MHR can be predicted with similar accuracy in subjects with and without MR, provided DS is accounted for in the equation for the subjects with MR.
