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.
