Interaction of biomechanical variables in the composition of visual augmented feedback for learning cycling

Abstract

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.
