Key result
A 4-week workplace cycling intervention increased maximum oxygen consumption from 2.07 to 2.17 L/min (P<.01) and improved HDL cholesterol in sedentary office workers.
Why the study?
Cycling workstations improve cardiometabolic risk factors in laboratory settings, but their effects following an intervention in the workplace needed to be quantified.

p-value: p=<.01
A 4-week workplace cycling intervention in sedentary office workers significantly improved V˙O2max and HDL cholesterol without decreasing other physical activity.
Supports brief workplace cycling to improve fitness and HDL in sedentary workers; extends RCT evidence for activity interventions.
BACKGROUND: In laboratory settings, cycling workstations improve cardiometabolic risk factors. Our purpose was to quantify risk factors following a cycling intervention in the workplace. METHODS: Twenty-one office workers who sat at work ≥6 hours per day underwent baseline physiological measurements (resting blood pressure, blood lipid profile, maximum oxygen consumption [V˙O2max], body composition, and 2-h oral glucose tolerance test). Participants were randomly assigned to a 4-week intervention only group (n = 12) or a delayed intervention group (n = 9) that involved a 4-week control condition before beginning the intervention. During the intervention, participants were instructed to use the cycling device a minimum of 15 minutes per hour, which would result in a total use of ≥2 hours per day during the workday. Following the intervention, physiological measurements were repeated. RESULTS: Participants averaged 1.77 (0.48) hours per day of cycling during the intervention with no changes in actigraphy-monitored noncycling physical activity. Four weeks of the workplace intervention increased V˙O2max (2.07 [0.44] to 2.17 [0.44] L·min-1, P < .01); end of V˙O2max test power output (166.3 [42.2] to 176.6 [46.1] W, P < .01); and high-density lipoprotein cholesterol (1.09 [0.17] to 1.17 [0.24] mmol·L-1, P = .04). CONCLUSIONS: A stationary cycling device incorporated into a sedentary workplace for 4 weeks improves some cardiometabolic risk factors with no compensatory decrease in noncycling physical activity.

Peterman et al. (2019) conducted an RCT in Sedentary office workers (n=21). Workplace cycling device vs. Delayed intervention (control condition) was evaluated on Maximum oxygen consumption (V˙O2max) (p=<.01). A 4-week workplace cycling intervention increased maximum oxygen consumption from 2.07 to 2.17 L/min (P<.01) and improved HDL cholesterol in sedentary office workers.
