“…The main research questions that have been frequently asked in these studies are on: (a) whether such movements can be considered normal or abnormal [2,3], (b) understanding and explaining the mechanisms and processes underlying the acquisition of these movements [4,5], and (c) raising subsidies to elaborate new programs for physical practice and therapies [1]. …”

BackgroundThe time synchronization is a very important ability for the acquisition and performance of motor skills that generate the need to adapt the actions of body segments to external events of the environment that are changing their position in space. Down Syndrome (DS) individuals may present some deficits to perform tasks with synchronization demand. We aimed to investigate the performance of individuals with DS in a simple Coincident Timing task.Method32 individuals were divided into 2 groups: the Down syndrome group (DSG) comprised of 16 individuals with average age of 20 (+/− 5 years old), and a control group (CG) comprised of 16 individuals of the same age. All individuals performed the Simple Timing (ST) task and their performance was measured in milliseconds. The study was conducted in a single phase with the execution of 20 consecutive trials for each participant.ResultsThere was a significant difference in the intergroup analysis for the accuracy adjustment - Absolute Error (Z = 3.656, p = 0.001); and for the performance consistence - Variable Error (Z = 2.939, p = 0.003).ConclusionDS individuals have more difficulty in integrating the motor action to an external stimulus and they also present more inconsistence in performance. Both groups presented the same tendency to delay their motor responses.

“…This knowledge allows the development of the most effective intervention techniques. In the DS cases, this background related to the motor control impairments can influences strategies for improve the Activities of Daily Living as well as the improve of quality of life (Mulvey et al, 2011). Regarding this background, the literature already have important findings about the DS effects on bimanual coordination (Mulvey et al, 2011), timing coincident capacity (Torriani-Pasin et al, 2013), motor learning synergies (Latash, 2007).…”

“…The main questions have frequently been raised on three points: whether such movements could be considered normal or abnormal (Mulvey, Ringenbach, & Jung, 2011); explaining and understanding their underlying motor processes and mechanisms (Mendonca, Pereira, & Fernhall, 2011), and; elaborating new practice schedules and therapies (Wuang et al, 2011).…”

With the present study, we aimed to investigate the task complexity effects on the performance of a coincidence timing task in individuals with Down syndrome. The experimental group was consisted by 26 subjects with Down syndrome, 20 years old (± 5), and classified as mild or moderate in International Classification of Functioning and Health. Each participant in the experimental group was matched by in function of gender and age with a participant in a control group without Down syndrome. Both groups performed a coincident timing task, in which the participant had different levels of structural and functional complexity. Performance measure was derived from the consistency (absolute error), accuracy (variable error) and direction of response (constant error). Individuals with Down syndrome presented spatiotemporal organization impairments related to the difficulty in dealing with motor demand in order to interact with the perceptive demand. They also experienced difficulty in adapt to task complexity, causing performance error in the task. Individuals with Down syndrome have deficits in perceptive and space-time organization, and this phenomenon may be explained by the difficulty in integrating perceptive stimulus to motor actions with a high number of elements involved.

“…One limitation of the current study comes from the fact that we do not have a control group and have not assessed the level of cognitive impairment of the swimmers. Recent literature suggests that disturbed coordination is in fact a genetic trait and less related to IQ itself (Mulvey et al, 2011). The swimmers were not used to the swimming pool where this experimental procedure took place, and it is possible that the familiarization might not have been optimal.…”

“…Furthermore, it is not apparent if the same breathing automatism might be found in experienced swimmers with Down syndrome as is seen in experienced swimmers without a disability. There is, for example, both an increased prevalence of non-right-handedness and evidence for reduced asymmetries in manual performance that might lead to additional problems while breathing in swimmers with Down syndrome even after extensive practice (see e.g., Mulvey, Ringenbach, & Jung, 2011). The first question is then what are some basic movement characteristics of front crawl stroke in experienced competitive swimmers with Down syndrome?…”

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.
