Study Arms (2)

Intervention group

EXPERIMENTAL

Participants in the intervention group will receive the Dynamic Working Intervention program, as described in the next section.

Other: Dynamic Work

Control group

NO INTERVENTION

Participants in the control group will not receive any intervention and will perform their work in the same manner as before.

Interventions

The intervention consists of the introduction of sit-stand workstations and desk bikes in the participants work environment in a ratio of 1:2 with traditional desks and chairs. Employees will receive a half hour intervention session at the start of the intervention from an occupational physiotherapist, who will provide further intervention support in the ensuing 12 weeks. Intervention participants will also receive an activity tracker which provides feedback on sitting time and physical activity levels.
