    … <p></p><p>The purpose of this study was to investigate the relationship between toe muscular strengths and single and/or repetitive jump performances on different directions (vertical or horizontal) in athletes. … Jump performances were assessed by press jump (vertical jump and standing broad jump) that measures jumping height or distance, and rebound jump (rebound jump and repetitive hopping) that measures "RJ-index" (the jumping height divided by the contact time). …

  • Kinetics of Charge Transfer through DNA across Guanine–Cytosine Repeats Intervened by Adenine–Thymine Base Pair(s)

    Osakada Yasuko , Kawai Kiyohiko , Majima Tetsuro

    … Several reasonable models, concerning delocalized charge over guanines (G’s) as well as localized charge on individual G’s, such as polaron and hopping mechanisms, are proposed based on theoretical and experimental research. … We previously reported the kinetic features of CT across the G and cytosine (C) repetitive sequence (GC repeats). … Thus, the data obtained here are not simply explained by G-hopping mechanisms, in which the charge localizes on individual G’s. …

  • Contribution the college research to the community through sports: case studies of senior's and children's static standing balance  [in Japanese]

    新宅 幸憲

    … Meanwhile, in the case of children with outstanding flexibility, children with strong athleticperformance in one-leg-standing, hopping, and repetitive side jumping were seen as having ashorter distance of change in the center of balance when standing. …

  • A VIRTUAL EVOLUTION STUDY : Simulation of the Evolution of Hopping Motions in Animals  [in Japanese]

    HASE Kazunori , YAMAZAKI Nobutoshi

    … That is, motions are reasonably adapted to the mechanical constraints of the body system, whereas a repetitive motion modifies body construction adapting to its motion. … Clarifying the mechanism of interactive adaptation between body shape and repetitive motions is helpful for studying evolutional processes in animals. …
