“…DS individuals are indeed more variable than typically developing individuals while practicing a graphic skill (cf. Gimenez et al 2006). In the present study, we have some evidence (from variability of sequence and relative timing variability) that the mild DS individuals showed a more stable action program in comparison with moderate DS individuals which takes us to the last research question concerned with the role of the level of handicap in the skill acquisition.…”

“…The present results need to be explored in further studies considering the relative temporal organization of the sequence which is a key element in identifying the action program particularly for individuals with Down syndrome (Henderson et al 1981;Gimenez et al 2006). One of the assumptions is that, in addition to memory limitations for ordering components, establishing temporal relations between them would be crucial as well (Conners et al 2008;Edgin et al 2010;Michael et al 2012).…”

“…Nevertheless, these two studies focused on motor control, i.e., the participants did not have practice in the task apart from what was necessary to become familiar with the experimental situation. Gimenez et al (2006) looked at action program formation in four mild DS individuals (mean age = 19.5 months) who practiced a graphic task. DS individuals did benefit from practicing a graphic task taken by the decrease on total movement time to perform the task showing very similar performance with that of the typically developing children and adults.…”

This study investigated the acquisition of a serial motor skill in individuals with Down syndrome with two levels of handicap, mild group (mean age = 14.5 years, SD = 2.3, 7 individuals) and moderate group (mean age = 15.2 years, SD = 3.2, 7 individuals). The task involved single-arm sequential movements to five. The measures to access performance were overall sequence error, reaction time, and total movement time. To evaluate action program, formation variability of sequencing and relative timing variability were considered. Although there was no clear practice effect, the results showed that the level of handicap led to different strategies to plan and control the actions. The moderate group presented a less stable action program expressed in the variability in sequencing and timing. Their longer reaction times also suggest a heavy demand on central processing in accord with the onetarget advantage hypothesis and also due to memory deficits to select and plan movements.

“…They sometimes require longer practice time and experience of a task, and so are able to improve their performance, developing learning skills and autonomy/self-control, which is based on concepts of neural plasticity and motor learning principles (Chiviacowsky, Wulf, Machado, & Rydberg, 2012;Berg, Becker, Martian, Primrose, & Wingen, 2012;Gimenez, Manoel, & Basso, 2006). According to this study, the intervention with hippotherapy sessions, in which they were subjected to the movement of the horse for 30 minutes per session, generating postural adjustments in practitioners with DS and no physical impairment led to the acquisition of motor skills through practice, resulting in better control of muscle activation of lower limbs.…”

ABSTRACT. Hippotherapy is a therapeutic method that uses the horse's movement to achieve functional results in practitioners with Down syndrome (DS), who present motor and neurophysiological changes that affect the musculoskeletal system. Evaluating the motor behavior related to the control and the improvement of muscle activation in practitioners with Down syndrome subjected to hippotherapy. 10 practitioners were divided into two groups: Down Group (DG) -practitioners with DS, and Healthy Group (HG) -practitioners with no physical impairment. The muscles gluteus medius, tensor fasciae latae, rectus femoris, vastus medialis, vastus lateralis, biceps femoris, tibialis anterior and gastrocnemius were evaluated by electromyography using gross RMS values, which correspond to muscle activation; the evaluations were performed on the 1 st and 10 th hippotherapy sessions (frequency: once a week), and after 2 months interval without treatment, they were performed on the 1 st and 10 th hippotherapy sessions (frequency: twice a week). It was noted that activation of the studied muscles increased with the passing of sessions, regardless the weekly frequency of attendance; however, the period without treatment resulted in reduction of this effect. Practitioners with DS presented satisfactory changes in muscle activation pattern, in learning and in motor behavior during hippotherapy sessions.Keywords: muscle activation, electromyography, hippotherapy, Down syndrome, equine assisted therapy.Avaliação eletromiográfica dos membros inferiores de pacientes com síndrome de Down na equoterapia RESUMO. Equoterapia é um método terapêutico que utiliza o movimento do cavalo para alcançar resultados funcionais, realizada em praticantes com síndrome de Down (SD), que apresentam alterações neurofisiológicas e motoras que afetam o sistema musculoesquelético. Avaliar o comportamento motor relacionado ao controle e melhora a ativação muscular em praticantes com SD submetidos ao tratamento equoterapêutico. Participaram dez praticantes divididos em dois grupos: grupo Down (GD) -praticantes com SD, e grupo Saudável (GS) -praticantes sem comprometimento físico. Os músculos glúteo médio, tensor da fáscia lata, reto femoral, vasto medial, vasto lateral, bíceps femoral, tibial anterior e gastrocnêmio foram avaliados por meio da eletromiografia, utilizando o valor de RMS bruto que corresponde à ativação muscular, e as avaliações foram realizadas na primeira e décima sessões de equoterapia (frequência: 01 vez por semana); e após intervalo de dois meses sem tratamento, foi realizada na primeira e décima sessões de equoterapia (frequência: 02 vezes por semana). Observou-se que a ativação muscular dos músculos estudados aumentou com o passar das sessões, independente da frequência semanal de atendimento; mas o período sem tratamento resultou em redução deste efeito. Os praticantes com SD apresentaram mudanças satisfatórias no padrão de ativação muscular, na aprendizagem e no comportamento motor no decorrer das sessões de equoterapia.Palavras-chave: ativa...

“…Especifi camente, esses autores Como deve ser o ensino do esporte e o que deve ser ensinado? A busca de resposta a essas perguntas tem uma longa história de pesquisas em Educação Física e Esporte, resultando na proposição de uma diversidade de métodos de ensino (GARGANTA, 1998;GRAÇA & OLIVEIRA, 1994;GRECO, 1998;RIGOLIN DA SILVA, 2006;DE ROSE JUNIOR, 2006;CORRÊA & TANI, 2006;REVERDITO & SCAGLIA, 2009;ROSSETTO JUNIOR, COSTA & D'ANGELO, 2008;TAVARES, GRAÇA, GARGANTA & MESQUITA, 2008;TANI, BENTO & PETERSEN, 2006). No entanto, quando se trata da verifi cação experimental dessas proposições, há de se reconhecer que, comparativamente, poucos estudos têm sido reportados na literatura (CORRÊA, SABINO da assunção de que o conhecimento sobre o processo de desenvolvimento motor humano constitui um elemento fundamental quando a matéria de ensino é o esporte.…”

O processo ensino-aprendizagem pode ser visto como um sistema constituído pela interação de três componentes - professor, aluno e matéria - que tem por meta promover mudanças efetivas nos comportamentos, capacidades e competências do aluno. Como numa visão sistêmica do processo ensino-aprendizagem, a função de um determinado componente implica sempre o estabelecimento de relação entre os dois componentes que restam, o papel principal do professor é estabelecer relação entre o aluno e a matéria. Neste contexto, a questão central é saber em que se basear para estabelecer essa relação. O presente ensaio parte da assunção de que o conhecimento sobre o desenvolvimento motor constitui um elemento fundamental quando a matéria de ensino é o esporte, discute uma fase desse processo que tem sido sistematicamente esquecida procurando identificar as suas possíveis causas e consequências e apresenta algumas sugestões para trabalhar com essa fase.
