Speciﬁcally, we were interested in how task performance, postural control and lower limb Cognitive tasks muscle activation changed when tasks were performed in motion compared to no motion conditions. The motion Maritime environments trials were performed on a MOOG 2000E that created a 5-degree of freedom simulated environment. The tasks examined were a lifting task, a mental arithmetic task and a visual tracking task. Results of this experiment indicated that two outcome measures of a visual tracking task
