Abstract
Abstract Study aim: This study clarified the relationship between sex and dominant and non-dominant feet during landing movements in the vertical drop jump (VDJ). Materials and methods: The participants were 16 healthy adults (8 men, 8 women) with no orthopedic history. A three-dimensional motion analyzer and a floor reaction force meter were used for measurement. The exercise task was a VDJ in which the participants jumped from a 30-cm-high platform, and the relationship between sex, dominant leg, and non-dominant leg was compared. Results: In terms of joint angle, the main effect of sex on the internal/external knee joint angle was observed. No significant differences were observed in the other parameters. Conclusions: A sex difference was found in the internal/external angles of the knee joint during the landing of the VDJ from 30 cm. However, there were no differences in the kinematic and kinetic data between the dominant and non-dominant legs.
