Outline of Final Research Achievements

In this study, to construct measurement system of leg motion analysis, impact force and electromyogram during exercise in the field, there were conducted that measurement of impact force at landing using acceleration sensor, estimation of three dimensional posture using inertial sensor, estimation of relationship between impact force and muscle activity, and quantification of muscle fatigue using electromyogram.
In consequence, there were verified that measurable of impact force at landing using acceleration sensor, predictability of posture using inertial sensor, and to constructing quantification method of muscle fatigue using electromyogram.
