Temporal relation between peak values in a single shake cycle of participant 16. (a) Instantaneous radius of curvature (IROC) of the head’s center of gravity during a single typical shake cycle. The instances at which the peak angular velocity and acceleration occur are indicated by vertical lines tω-peak and tα-peak respectively. (b) angular velocity of the head and angular acceleration of the head during a single typical shake cycle. The IROC was highly variable at some points in the shake cycle, also in the proximity of angular acceleration peaks.
