Each treadmill is equipped with an AC motor. In order to shorten the length of the treadmill, the motor is put underneath the belt. The power of each motor is 80 W and it is controlled by an inverter. The maximum speed of each treadmill is 1.2 m/s. The maximum acceleration is 0.8 m/s2. The deceleration caused by friction is 1.0 m/s2. The width of each belt is 250 mm and the overall walkable area is 1 m × 1 m.

The inclusion criteria were determined based on the PICOS search tool [31]: Population (P): sedentary workers (e.g., office workers) aged between 18 and 65 years with no medical conditions.Intervention (I): cycle desk or treadmill desk.Comparisons (C): conventional sitting.Outcome (O): objectively measured EE and cardiovascular (heart pressure, heart rate) and biochemical (blood glucose and insulin, cholesterol, triglycerides, cortisol, dopamine) indicators.Study design (S): randomized controlled trials (RCTs), non-randomized parallel group design study and crossover (CO) study designs.Other inclusion criteria were peer-reviewed articles published in the English language.

Stature and weight were measured using a stadiometer (Harpenden 98.602, Holtain Ltd., Crymych) and electronic weighing scales (Tanita Corp., Tokyo, Japan), respectively. Participants were then familiarised with the Borg Rating of Perceived Exertion (RPE) scale (Borg, 1982) and the Lifespan TR800-DT5 treadmill desk (LifeSpan, Salt Lake City, UT, USA) that was used during the experimental conditions. Participants then walked on the treadmill desk to determine a perceived light-intensity walking speed (RPE of 6–9) and this speed was then used for that respective participant in the relevant experimental condition. The treadmill desk walking speeds selected by the participants ranged between 1.2 and 3.5 km/h−1. Once the appropriate walking speed had been determined, participants walked at this speed for 15 min whilst typing about something meaningful to them on a laptop computer. The purpose of this was to confirm that the desk height and walking speed selected would be comfortable for the walking bouts performed in the relevant experimental condition (Alderman, Olson, & Mattina, 2014).
