| Outline of Final Research Achievements |
The leg behaves like a spring during running and jumping. Therefore, assessment of the spring characteristics (characteristics of counter movement) is important for athletic training and conditioning. The purpose of this study was to examine (1) the validity, reliability, and utility of a new method for assessment of the characteristics of the counter movement (Multi contact time jump test：MCT-jump test）, and (2) the utility of a new indicator to assessment of characteristics of counter movement (Optimal contact time: contact time to maximize jumping height in drop jump exercise) for athletic conditioning.
Our results show that MCT-jump test is a valid method for assessment of the characteristics of counter movement and Optimal contact time is an useful indicator to management of athletic conditioning.
