way to keep sedentary workers active at work, and improving their health. The researchers found that workers who pedaled more were more likely to report weight loss, improved concentration while at work, and fewer sick days than co-workers who pedaled less. The study appeared in the American Journal of Preventive Medicine.
"We wanted to see if workers would use these devices over a long period of time, and we found the design of the device is critically important," said Lucas Carr, assistant professor of health and human physiology at the University of Iowa in the US.
"It is a great idea in theory, but it does not work over the long haul for most people," Carr noted.
The new 16-week pilot study tested the effectiveness of portable pedal machines among 27 workers with sedentary jobs. At the end of the study, 70 percent of participants chose to keep their pedaling device.
