| Research Abstract |
In humans, the most common daily movements are walking and running. The plantar flexor muscles and the foot arch contribute to braking and propulsion in these movements. The triceps surae muscle-tendon unit (TS-MTU), which is the main contributor to the plantar flexion, inserts on the calcaneus. Thus, it was expected that the TS-MTU would interact with the foot arch. In adolescent, although heel pain is one of the most major complaints, the mechanism of development of the pain is still unclear. In order to accumulate fundamental knowledge of the mechanism, the present study determined the structure and behavior of the foot, and interaction between foot arch and the TS-MTU in adolescents and adults. As a result, 1) the foot in adolescents was more compliant than that in adults, 2) the TS-MTU length change during ankle joint movement was smaller in adolescents than in adults.
