Explore this experimental dataset stemming from a scientific publication for which its author, Baptiste Sandoz, was honored with the 2019 Young Investigator Award from the Society of Biomechanics

This dataset comprises experimental data obtained from lateral acceleration experiments conducted on five human volunteers seated in various configurations: upright posture or sagged posture, relaxed muscles or contracted muscles.

While low-intensity frontal accelerations have been extensively investigated, the human body's response to various lateral accelerations remains not well understood. Hence, the objective of this study is to gather insights into the responses of seated individuals subjected to lateral perturbations with varying shapes and magnitudes. A profound understanding of stabilization strategies is essential for predicting their kinematics in external dynamic environments, such as those encountered by vehicle passengers.

The study reveals that not only the magnitude of the impulse but also its shape influences human responses to low accelerations. Interestingly, the posture of the subjects was found to have no significant impact on lateral head bending. These data can be valuable for evaluating active numerical models of the human body and its responses
