Pointe Shoe Stiffness Alters the Vertical Ground Reaction Force During Single-Leg Drop-Landing in Female Ballet Dancers

Natsuki Yoshida, Issei Ogasawara, Kaho Umegaki, Satoshi Yamakawa et autres

Introduction: It is well known that the pointe shoes are essential for ballet’s unique postural control and repetitive wear makes the pointe shoes vary in stiffness. However, the effects of different shoe stiffness conditions on the vertical ground reaction force (vGRF) in …

The counteracting effect of the friction moment against the tibial rotational moment driven by the ground reaction force in an early stance phase of cutting maneuver among healthy male athletes

Issei Ogasawara, Megumi Nambo, Yuki Uno, Gajanan S. Revankar et autres

The ground reaction force (GRF) is known to produce tibial internal rotation loading associated with the stress in the anterior cruciate ligament (ACL). However, it is unclear whether the friction moment (FM; the moment due to horizontal shoe-floor friction, acting around the …

Effect of the foot-strike pattern on temporal characteristics of sagittal plane knee kinetics and kinematics during the early phase of cutting movements

Yuki Uno, Issei Ogasawara, Shoji Konda, Kaito Wakabayashi et autres

Abstract Anterior cruciate ligament (ACL) injury occurs soon after foot-strike. Cutting with a shallow flexed knee is considered a risk factor for ACL injury; however, how foot-strike patterns (forefoot strike [FFS] vs. rearfoot strike [RFS]) affect sagittal plane knee kinetics and kinematics …
