Nordic-pole walking speed effects on muscle forces working against gravity

Currently, elderly people of 65 years and older constitute 29.1% Japan’s population. Frail patients are 8.7% all older. Frailty is a weak state both physically mentally. The probability illness increases with age. Pole walking an exercise designed to improve muscle strength thereby prevent frailty in people. This study applied musculoskeletal model analysis during pole normal clarify training effects balance effects. Seven 35 plug-in gait markers attached the body surface were examined for this study. Normal measured using three-dimensional motion system (Vicon Motion Systems) two force plates. Position data acquired at velocities 58, 77, 96 bpm. Measured analyzed software (OpenSim) procedures: scaling, inverse kinematics, residual reduction algorithm, dynamics, computer control. Results obtained indicate details force, lower limb joint moments, lumbar moments walking. effective muscles working against gravity cases speed (58 bpm). However, higher (96 bpm) associated better conditions training.
