| Research Abstract |
The purpose of the present study is to examine effects of the different sport activities on the tendon architectures. The 650 sport athletes were volunteered for this study. The length and cross-sectional area (CSA) for Achilles and patella tendons were measured by the musculoskeletal ultrasonography. The results showed that the tendon length and CSA of the dominant leg were significantly greater than those of non-dominant leg in the shot-put and high-jump athletes. The CSA of the swimmers was significantly smaller than other sport athletes. Our results suggest that the specific tendon adaptation can be occurred only in the high-impact sport activities.
