Objective:
The purpose of this study was to examine how intensity of wave motions affects the performance of a simulated maritime search and rescue (SAR) task.
Background:
Maritime SAR is a critical maritime occupation; however, the effect of wave motion intensity on worker performance is unknown.
Methods:
Twenty-four participants (12 male, 12 female) performed a simulated search and rescue task on a six-degree-of-freedom motion platform in two conditions that differed in motion intensity (low and high). Task performance, electromyography (EMG), and number of compensatory steps taken by the individual were examined.
Results:
As magnitude of simulated motion increased, performance in the SAR task decreased, and was accompanied by increases in lower limb muscle activation and number of steps taken.
Conclusions:
Performance of an SAR task and balance control may be impeded by high-magnitude vessel motions.
Application:
This research has the potential to be used by maritime engineers, occupational health and safety professionals, and ergonomists to improve worker safety and performance for SAR operators.
