Trajectory of the human body mass centre during walking at different speed

The major objective of this paper was to investigate the influence of walking speed on trajectory of the body mass centre during human walking. An automatised method for determination of the total body centre of mass has been established. Measurements have been applied to 52 subjects with no apparent abnormalities of the locomotion system, using the Elite motion analyser. The range of walking speed was 0.95 m/s - 2.4 m/s, where the speed 1.7 m/s represented the limit speed between normal and fast gait. A typical pattern of trajectory of the body mass centre during gait cycle has been established for every subject and general pattern for normal and fast gait has been determined from typical patterns. The determined mean values of normalised components of trajectories of body mass centre have been compared and the differences between gait at normal and fast speed have been described.
