Outline of Final Research Achievements

In healthy athletes and athletes after ligament reconstruction, the joint angle, muscle activation, landing impact, and balance during single-leg jump-landing and physical function were measured on purpose to show scientific information of motion instruction at flight phase for prevention of knee ligament primary/secondary injury which tends to occur during jump landing. In the healthy athletes, the landing impact was correlated with pelvis inclination and knee flexion angles. In the athletes after ligament reconstruction, the landing impact was correlated with leg leach distance and knee extension strength. These results were presented in journal, congress, symposium, seminar, and web.
