Outline of Final Research Achievements

This study identified the conditions for a drop weight impact test that can apply a load to the springboard equivalent to that of an actual takeoff motion. During this process, it was revealed that when a load equivalent to that of an actual takeoff motion is applied, the differences in mechanical properties between springboards manufactured by different companies, despite adhering to the same standards, are significant enough to affect the execution of take-off motion. These findings suggest that there are still aspects of the springboard standards that are considered inadequate and indicate directions for improvement.
The results of the drop weight impact test under the identified conditions showed that the optimal takeoff area on the springboard is not a narrow, pinpointed region near the tip, but rather a relatively broad area extending from the tip towards the center.

Academic Significance and Societal Importance of the Research Achievements

跳躍板の踏み切りに適した範囲を明らかにしたことで，試行錯誤のみで踏み切り位置を絞り込む必要が無くなっていき，それによって，経験のみに頼るよりも効率的で安全なトレーニングが可能になっていくことが期待される．さらに，現時点で存在している跳躍板で踏み切りに適した範囲が明らかになっただけでなく，将来，跳躍板の新型モデルが登場した時に，本研究で確立した機械的な特性試験を実施するだけで踏み切りに適した範囲を予測することも可能になるため，本研究の成果は持続的な貢献になっていくことが期待される．
