RESUMO
O objetivo do estudo foi avaliar a aceleração do movimento e o desempenho de adolescentes com Síndrome de Down e de com desenvolvimento típico durante o arremesso no jogo de boliche do videogame Nintendo® Wii™. Os participantes foram 20 adolescentes, com idade entre 7 e 14 anos, divididos em dois grupos: GSD (Grupo Síndrome de Down) e GC (Grupo Controle). Ambos os grupos fizeram os arremessos necessários para a finalização do jogo com a mão de preferência e um acelerômetro acoplado ao punho. Os dados foram analisados considerando-se apenas os 3 primeiros arremessos. Observou-se que a aceleração máxima média foi maior para o GC em todas as tentativas, porém com o número médio de tentativas equivalente para alcançar o objetivo do jogo. O boliche apresentou-se ao GSD como uma proposta de fácil compreensão, motivadora e com regras simples. Conclui-se que os jogos de arremesso no ambiente virtual podem favorecer o controle de aceleração do movimento.
The aim of this study was evaluate the acceleration of the movement and performance of adolescents with Down Syndrome and with typical development in pitch movements in the game of bowling video game Nintendo® Wii™. The subject were 20 adolescents, aged between 7 and 14 years, divided into two groups: GSD (Group Down Syndrome) and GC (Control Group). Both of them did the throws necessary to complete the game with the hand of preference and the accelerometer attached to the wrist. The data were analyzed considering only the first 3 pitches. It was observed that the maximum acceleration mean was higher for the GC in all attempts, however, but with the average number of equivalent attempts to achieve the goal of the game. The bowling presented the GSD as a proposal for easy understanding, as a motivational activity and with simple rules. The conclusion show that pitch games in the virtual environment can encourage the throttle control of movement.

Resumo O objetivo deste estudo foi correlacionar características biomecânicas do membro superior durante o arremesso da bocha adaptada e do jogo boliche do Kinect Sports do videogame Xbox da Microsoft Games Studios®. Participaram da pesquisa oito atletas, cinco classificados como BC2 e três como BC4. Foram coletadas medidas das angulações de punho e cotovelo e da velocidade linear média dos arremessos mais eficientes por meio de filmagens para análise cinemática. Foram encontradas semelhanças nas angulações de punho e cotovelo e na velocidade linear média dos arremessos em ambas as situações. Dessa forma, conclui-se que o uso da realidade virtual é um fator a ser considerado no treinamento da bocha adaptada.
Abstract The objectives of this study were to correlate biomechanical characteristics of the upper limb during the throw of the boccia and bowling game Kinect Sports Xbox video game from Microsoft Games Studios®. The participants were 8 athletes, 5 classified as BC2 and BC4 as 3. Measurements of the angles of wrist and elbow and the average linear velocity of the most effective pitches through footage for kinematic analysis were collected Similarities were found in the angles of wrist and elbow and the average linear velocity of pitches in both situations. Thus, it is concluded that the use of virtual reality is a factor to be considered in the training of boccia.
Resumen Los objetivos de este estudio fueron establecer una correspondencia entre las características biomecánicas de la extremidad superior durante el lanzamiento en la bocha y las mismas en el videojuego de bolos Kinect Sports Xbox de Microsoft Games Studios®. Participaron 8 deportistas, 5 clasificados como BC2 y 3 como BC4. Se tomaron las medidas de los ángulos de la muñeca y el codo, y la velocidad lineal media de los emplazamientos más eficaces a través de imágenes para el análisis cinemático. Se encontraron similitudes en los ángulos de la muñeca y el codo, y la velocidad lineal media de lanzamiento en ambas situaciones. Por tanto, se concluye que el uso de la realidad virtual es un factor que debe tenerse en cuenta en el entrenamiento de la bocha.
RESUMO
To examine the effect of long lasting practice on pedal behavior in sport, we compared experienced adult soccer players and nonsoccer players on leg preference in motor tasks requiring general mobilization, soccer related mobilization, and body balance stabilization. We also evaluated performance asymmetry between the right and left legs in static and dynamic unipedal body balance, based on center of pressure displacement, and correlated that with leg preference in balance stabilization tasks. Results revealed (a) a distinct leg preference between mobilization and stabilization tasks, which were significantly different between players and nonplayers, (b) similar balance stability between the right and left legs, (c) greater stability of experienced players compared with nonplayers in static and dynamic balance, and (d) absence of a significant leg preference correlation with interlateral balance asymmetry. These results suggest an effect of extensive soccer skill practice on establishing leg preference for specific mobilization tasks and overall balance control.
