The purpose of this study was to examine the impact of an after school physical activity intervention on adolescents with visual impairments within the context of Social Cognitive Theory. Four adolescents with visual impairments (1 female, 3 males) between 14 and 19 years of age from a residential school for the blind served as participants. We used a range-bound changing criterion single-subject design. Physical activity was measured using ActiGraph accelerometers. Questionnaires were used to obtain information on selected social cognitive theory constructs. Results show that the intervention exerted functional control over the target behaviors (e.g., leisure-time physical activity) during intervention phases. Similarly, changes in scores for selected social cognitive constructs, in particular for outcome expectancy value, suggest a positive relationship between those constructs and physical activity behavior. No maintenance effects were observed.

Children with developmental coordination disorder (DCD) experience difficulty performing everyday motor tasks. It is has been suggested that children with DCD have fewer self-regulatory (SR) skills with which to acquire motor skills. This article presents the results of an exploratory study examining the development of SR competence among ten 7–9-year-old children with DCD participating in the Cognitive Orientation to daily Occupational Performance (CO-OP) program (Polatajko & Mandich, 2004). Using a quantitative observational coding method, children’s SR behavior was examined and compared across intervention sessions. Results indicate that children demonstrating improved motor performance similarly demonstrated more independent and effective SR behaviors. In contrast, children whose motor performance remained relatively stable failed to demonstrate such a change. These findings suggest that CO-OP enables SR performance among children with motor performance difficulties and, as a result, facilitates improved task performance.

As a first step toward the development of adapted physical activity (PA) programs for adults with visual impairment (VI), the purpose of this study was to determine the time frame needed to reliably estimate weekly PA in adults with VI. Thirty-three adults with VI completed 7 days of pedometer-based PA assessment. Generalizability theory analyses were conducted to quantify sources of variance within the PA estimate and determine the appropriate number of days of PA monitoring needed for the total sample and for participants with mild-to-moderate and severe VI. A single-facet, crossed design was employed including participants and days. Participants and days correspondingly accounted for 33–55% and 0–3% of the total variance in PA. While a reliable account of PA was obtained for the total sample over a 6-day period, shorter (4-day) and longer (9-day) periods were required for persons with mild-to-moderate and severe VI, respectively.

This study examined the differences in intracycle velocity variation and arm coordination in front crawl in swimmers with Down syndrome in three breathing conditions. International swimmers with Down syndrome (N = 16) performed 3 × 20 m front crawl at 50 m race speed: without breathing, breathing to the preferred side, and breathing to the nonpreferred side. A two dimensional video movement analysis was performed using the APASystem. Breathing conditions were compared using Repeated Measures ANOVA. Swimming velocity was higher without breathing and intracyclic velocity variation was higher while breathing. Swimmers tended to a catch up arm coordination mode for both breathing conditions and a superposition mode when not breathing. These data reflect arm coordination compromising swimming performance, particularly when comparing with non disabled swimmers in literature. The physical and perhaps cognitive impairment associated with Down syndrome may result in a disadvantage in both propulsion and drag, more evident when breathing.

The purpose of this study was to examine the physical activity patterns of older adults with intellectual disabilities (ID) in comparison with younger adults with ID and older adults without ID. A sample of 109 participants was included in the study. Sophisticated data reduction, time stamped technology, and multiple objective measures (i.e., pedometers and accelerometers) were used to determine physical activity intensities and walking patterns of participants. Results indicate that older adults with ID are performing less physical activity than comparison groups. A small proportion of older adults with ID (6%) met national physical activity recommendations of 150 min of moderate or 75 min of vigorous physical activity in bouts greater than ten minutes across the week (USDHHS, 2008). Sedentary behavior was also an observable factor in this study. These findings demonstrate the need for health promotion efforts for adults with ID across the lifespan.

Traumatic brain injury (TBI) is a significant public health issue due to the incidence, complexity, and cost associated with treatment. The purpose of this study was to determine physical activity (PA) knowledge, attitudes, intentions, and barriers among individuals with a TBI undergoing outpatient rehabilitation. Seventeen participants completed a series of group interviews regarding their PA needs. A qualitative research design was adopted and trustworthiness was established through investigator triangulation of data. A cross-case analysis was completed to identify themes and conceptual patterns. The main themes identified were (a) an inability to differentiate between PA and physical therapy, (b) a limited knowledge of PA health benefits and the relationship to rehabilitation, and (c) an interest in participating in a PA based health promotion program. Future interventions should educate individuals about PA, the associated health benefits, and the role PA plays in the rehabilitation process.
The experience of participation in physical activity was explored in a qualitative study with twenty Norwegian adults with physical and visual disabilities. The interviews showed that more than 75% of negative experiences reported in this study originated from physical education (PE), suggesting that this was a particularly challenging arena. The negative experiences were centered in these common themes: experiences of not being included, experiences of failing, and experiences of not being listened to. The interviews were analyzed applying an existential-phenomenological approach. The participants with relatively minor degrees of disability and with the least visible disabilities were the ones who most often reported negative experiences regarding PE. This suggests the experiences were not generated solely by the actual physical or sensory limitations, but equally by how well the participants’ challenges were understood by their teachers and to what degree adaptations were implemented.
