| Outline of Final Research Achievements |
In this study, The group of eccentric contraction with down-hill running indicated an increase of calcified fibrocartilage zone compared to other exercise groups in animal experiment. These results suggested the factors of bone and cartilage disease in growth phase were affected by specificity of mechanical stress not primitive overuse.
From the biomechanical studies, although increasing of the knee moment affected by trunk alignment, muscle activities were not changed in lineary. These results suggested that the inconsistency of mechanical stress and muscle activities related to the mechanism of bone-cartilage disease in growth phase. Our results explained eccentric contraction may induce the inflammation of bone insertion site.
