The aim of this study is to compare and analyze the joint pathway of ankle, knee, hip, trunk, shoulder, elbow joints.
A total of 30 healthy adults who were participated in this study for the three minutes. This study measured joint pathway and muscle activity with 3D motion analysis and EMG according to the height of bicycle saddle. One way repeated ANOVA was used to compare experimental value..
As a result, muscles activity were statistically significant differences in TA, RF, DEL, LD muscles in all saddle height(p<.05). But there were no difference in TRI and ES muscles(p>.05). Furthermore, joint pathway were statistically significant differences in ankle, knee, hip, trunk, shoulder joints except elbow joint(p<.05)..
In this study, it suggested that as the height of the saddle increases, the angle and the pathway of joints increases, and the muscle activity caused by the joint movement of the joint increases.
