A 12-Week Cycling Workstation Intervention Improves Cardiometabolic Risk Factors in Healthy Inactive Office Workers.

OBJECTIVES:The aim of this study was to evaluate the effects of a portable pedal machine intervention (60 minutes per working day) for 12 weeks on healthy tertiary employees' cardiometabolic risk factors. METHODS:Anthropometric parameters, body composition, cardiometabolic/inflammatory markers, physical fitness, physical activity, and sedentary time measured before and after the intervention were compared between office healthy workers who used a portable pedal machine (INT, n = 17) and those who did not (CTRL, n = 15). RESULTS:The INT group improved Δultrasensitive C-reactive protein ( P = 0.008), Δtotal cholesterol ( P = 0.028), and Δlight-density lipoprotein cholesterol ( P = 0.048) compared with the CTRL group (Δ: T1-T0). The intervention reduced daily sitting time ( P ≤ 0.01) and increased time spent at light intensity ( P ≤ 0.01) and moderate-to-vigorous ( P ≤ 0.01) physical activity compared with baseline values. CONCLUSIONS:These findings suggest that promoting physical activity during workdays can reduce the negative health effects of spending too much time sitting and inactive.
