• Description:
  Purpose ; To evaluate the effects of light intensity physical activity using a pedal desk (PD) compared to a standard desk (STD) in a pilot study on postprandial metabolic responses and work skills. ; Methods ; Twelve overweight/obese full-time sedentary office workers (6 men and 6 women; BMI= 28.7 ± 3.6 kg/m2) were tested in two conditions: (1) PD: pedaling at self-selected light intensity pace for 2-hr and (2) STD: remaining seated for 2-hr in a conventional workstation set up, while performing scripted computer-based work tasks. Blood samples were analyzed for plasma glucose, insulin, and free-fatty acids (FFA) in response to a standardized meal and work skills were evaluated. Paired samples t-tests were used to examine the differences in metabolic responses and work performance tasks between the conditions. ; Results ; PD use required significantly less insulin to maintain glucose concentrations compared with STD condition (peak insulin concentration 42.1 vs. 66.9 μU/mL, p = 0.03, and AUC 302.6 vs. 441.8 μU.min/mL, p < 0.001). No significant changes in plasma glucose and FFA concentrations were observed at any time-points (all p > 0.05). In addition, pedaling at a self-paced rate caused no adverse effects on work skills (p > 0.05). ; Conclusions ; The PD resulted in lower post-meal insulin concentrations without an overall negative impact on work skills. Thus, the PD could have the potential to achieve public and occupational health goals in sedentary work environments.
