Altering Postures – Value? (04-10-18)

Schwartz and his team studied the implications of changing postures while working – in other words standing after a period sitting or sitting after a time standing.  They learned that when “Subjects executed validated cognitive tests (working speed, reaction time, concentration performance) either in sitting or alternating working postures on two separate days . . . . results suggest that working posture did not affect cognitive performance in the short term.. . .working in alternating body postures did not influence reaction time, concentration performance, working speed or workload perception in the short term. . . . further research . . . is warranted and needed to determine whether there is a long-lasting effect of alternating working postures on cognitive performance and workload.”
