- Abstract
In this study, the effect of the dynamic bike fitting, which was defined as lower limb vertical alignment by inserted wedges, was evaluated. Twelve non-cyclists are participated in this experiment. For comparing pedaling performance between before and after fitting, sub-maximal pedaling tests were conducted for 2 min. The results showed that both the range of motion of the knee joint (medio-lateral direction) which represented pedaling trajectory and the coefficient of variance of pedaling power were decreased in non-cyclists. This result indicated that the dynamic fitting had a positive effect such as increased pedaling kinematic stability and kinetic efficiency on pedaling performance. Supplementary pedaling test was performed by one of the best cyclist, who was a member of the national team and a middle and long distance cyclist. The result of the cyclist test was also similar to the patterns of 12 non-cyclists. It is believed that this study has the meaning of the preliminary study to evaluate the effects of the dynamic fitting. Further study is necessary to evaluate the effects of the fitting through enough subjects and repeated tests by measuring muscle activities and forces.
