HOLDERBAUM, Guilherme Garcia; PETERSEN, Ricardo Demétrio de Souza y GUIMARAES, Antônio Carlos Stringhini. Interação de variáveis biomecânicas na composição de "feedback" visual aumentado para o ensino do ciclismo. Rev. Bras. Educ. Fís. Esporte [online]. 2012, vol.26, n.04, pp.553-569. ISSN 1981-4690.
The aim of this study was to test a methodology to teach the pedaling technique of cycling using biomechanics variables to develop an augmented visual feedback system (AVF). Nineteen subjects divided in two groups (experimental = 10 and control = 9) without experience in cycling were used. A pre-test was conducted to determine the maximal oxygen uptake (VO2máx), and to establishe the work load to be used during the learning sessions which was defined to be the load that was associated with the 60% of VO2máx. Seven practice sessions were held. The experimental group was submitted to AVF and the control group to augmented feedback (AF). After the practice sessions, the retention test showed a significant increase in the index of effectiveness (IE) for the experimental group of 21% compared to the control group. These results showed that the biomechanics variables were appropriated to the development the AVF system and can contribute in the process pedaling technique learning.
