Metabolic cost and speech quality while using an active workstation.

Background: The effect of active workstation implementation on speech quality in a typical work setting remains unclear.

Purpose: To assess differences between sitting, standing, and walking on energy expenditure and speech quality.

Methods: Twenty-two females and 9 males read silently, read aloud, and spoke spontaneously during 3 postural conditions: sitting, standing, and walking at 1.

The effect of active workstation use on measures of cognition, attention, and motor skill.

Background: The purpose of this study was to assess participants' ability to perform tasks requiring attention, short term memory, and simple motor skill while sitting, standing or walking at an active workstation.

Methods: Fifty participants completed the Stroop Color Word test (SCWT), Auditory Consonant Trigram test (ACTT), and Digital Finger Tapping test (DFTT) while sitting, standing and walking 1.6 km/h at an active workstation.
