Outline of Final Research Achievements |
The purpose of this study was to examine the usefulness of change of direction deficit (CODD), the difference between change of direction (COD) time and sprint time, as a measure to evaluate COD ability. The results showed that CODD might not reflect the running speed aspect of COD, and that it did not correlate with lower limb power parameters or changes due to training to increase COD ability. Therefore, it was suggested that there are many uncertainties in evaluating COD ability with CODD, and in some cases, the evaluation of COD ability may be misleading.

Academic Significance and Societal Importance of the Research Achievements |
方向転換(change of direction:COD)能力は、球技スポーツ選手にとって不可欠な体力要素である。本研究は、COD deficitによるCOD能力の評価の可能性について検討したが、結果的に指標としての不確定さの一端を明らかにすることとなり、その点では学術的に意義があるといえるだろう。また、得られた知見は球技スポーツ選手の体力評価の他に、トレーニングや運動指導の場面に活用することができ、その点で社会的意義は少なからずあると考えられる。
