Shoma Kudo, Student in the Graduate School of Sport and Health Science, published a research paper in Gait & Posture, co-authored with Professor. Akinori Nagano and Dr. Takahiko Sato at the College of Sport and Health Science, and Dr. Masahiro Fujimoto at National Institute of Advanced Industrial Science and Technology.

The importance of the trunk has been well recognized to contribute considerably to achieving and controlling human locomotion, such as walking and running, serving as a linking segment between the lower and upper limbs. This paper determined the optimal rigid-body model of the trunk for the analysis of its movement during walking and running. The findings of this study would be useful to analyze complex movements of the trunk during human locomotion.

 Takahiro Tanaka is Graduate Student of Sport and Health Science of Ritsumeikan University, and his research manuscript was accepted and published in Transactions of the JSME, which collaborated with Professor Tadao Isaka, Akinori Nagano, Associate Professor Kazumasa Ozeki in Osaka University of Health and Sport Science, Dr. Masahiro Fujimoto in National Institute of Advanced Industrial Science and Technology and Assistant Professor Toyoyuki Honjo in National Defense Academy.

The purpose of this study was to investigate the effect of leg extension timings during kick-start on swimming start performance. As a result, for the swimmer take-off downward, earlier front leg extension timing would allow them to generate a greater horizontal take-off velocity on kick-start.
