Abstract(s)
O objetivo deste estudo foi comparar as diferenças cinemáticas entre a análise digital
2D e 3D em movimentos do ciclismo que ocorrem maioritariamente no plano sagital.
Participaram no estudo 8 indivíduos do sexo masculino, praticantes de ciclismo
recreativo, com uma idade de 23± 3 anos, uma altura de 1,70m± 0,05 e um peso de
70kg± 5kg. Os atletas pedalaram numa bicicleta assente em rolos e utilizaram 2
posições de guiador. Foram utilizadas 3 camaras e colocados marcadores reflexivos na
bicicleta e no atleta. Os resultados obtidos não evidenciaram diferenças significativas
entre os métodos 2D e 3D nas variáveis estudadas, o que nos permite sugerir que em
futuras investigações similares possam ser adotados procedimentos de análise 2D,
minimizando assim a complexidade dos recursos utilizados e a quantidade de dados a
analisar.
The aim of this study was to compare the differences between the kinematic analysis in digital 2D and 3D movements of cycling that occur mostly in the sagittal plane. A sample of 8 males practitioners of recreational cycling, with an age of 23 ± 3 years, height of 1.70 ± 0.05 m and a weight of 70kg ± 5kg. The athletes pedaled a bicycle based on rolls and used 2 position handlebar. We used three cameras and reflective markers placed on the athlete and on the bike. The results showed no significant differences between the methods in 2D and 3D variables, allowing us to suggest that in future similar investigations can be adopted 2D analysis procedures, thus minimizing the complexity of the resources used and the amount of data to analyze.
