HOLDERBAUM, Guilherme Garcia; PETERSEN, Ricardo Demétrio de Souza  and  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 (VO_2máx), 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 VO_2máx. 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.
