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.

The aim of this paper is to show how images of disability are portrayed in physical education textbooks for secondary schools in Spain. The sample was composed of 3,316 images published in 36 textbooks by 10 publishing houses. A content analysis was carried out using a coding scheme based on categories employed in other similar studies and adapted to the requirements of this study with additional categories. The variables were camera angle, gender, type of physical activity, field of practice, space, and level. Univariate and bivariate descriptive analyses were also carried out. The Pearson chi-square statistic was used to identify associations between the variables. Results showed a noticeable imbalance between people with disabilities and people without disabilities, and women with disabilities were less frequently represented than men with disabilities. People with disabilities were depicted as participating in a very limited variety of segregated, competitive, and elite sports activities.

The purpose of this study was to determine preferences of people with spinal cord injury (SCI) and health care professionals (HCP) regarding the content and format of a SCI physical activity guide to support recently released SCI physical activity guidelines. Seventy-eight people with SCI and 80 HCP completed a survey questionnaire. Participants with SCI identified desired content items and their preferences for format. HCP rated the helpfulness of content items to prescribe physical activity. All content items were rated favorably by participants with SCI and useful by HCP. The risks and benefits of activity and inactivity, and strategies for becoming more active, were rated high by both samples. Photographs and separate information for those with paraplegia versus tetraplegia were strongly endorsed. These data were used to guide the development of an SCI physical activity guide to enhance the uptake of physical activity guidelines for people with SCI. The guide was publically released November 11, 2011.

The purpose of this study was to investigate rater effects on the TGMD-2 when it applied to children with intellectual disability. A total of 22 children with intellectual disabilities participated in this study. Children’s performances in each of 12 subtests of the TGMD-2 were recorded via video and scored by three adapted physical activity specialists who have expertise in the TGMD-2. Two advanced measurement theories, Generalizability-theory (G-theory) and many-facet Rasch model (MFRM), were applied in data analyses. There were relatively large variances attributed to rater effects on the scores of the TGMD-2 awarded to children with intellectual disabilities. The severity of each rater significantly differed across all subtests of the TGMD-2. There was a set of biased ratings interacted with measurement conditions of the TGMD-2.
