'Pedal while we work' idea raised by scientists in US

Woman at work Mini exercise bikes could combine a desk job with a workout 

Portable pedal machines could be used in every office to improve the health of 
workers, according to scientists in the US.

The researchers, writing in the British Journal of Sports Medicine, said 
sedentary lifestyles were a serious health problem.

They argue that small exercise bikes could be a cheap solution.

Charity Weight Concern said improving the health of workers would also benefit 
employers' bottom lines.

Hours spent sat a desk staring into a computer screen is not an alien 
experience for many office workers.

Physical inactivity has been linked to obesity, heart disease and diabetes.

Previous attempts at increasing the health of workers have involved hooking a 
treadmill up to an office computer.

Now researchers at East Carolina University are investigating mini exercise 
bikes, which can be used while sat at a desk.

    If used regularly, not only would individuals benefit, but employers would 
see reduced absenteeism and improved performance and job satisfaction"

During a small study with 18 workers, they assessed how feasible it would be 
for the bikes to be introduced.

On average, the workers each used the machine on 12 out of the 20 days of the 
study and pedalled for 23 minutes at a time.

In a questionnaire, the workers said they would use the machine regularly at 
work if they were offered one by their employer.

They researchers said: "Portable pedal machines may serve as a tool to reduce 
sedentary times in the work environment without necessarily influencing the 
sitting time necessary for performing computer-related tasks."

The authors note that the novelty factor of having an exercise bike did wear 
off so additional motivation would be needed to keep employees using them.

Dr Ian Campbell, of Weight Concern, said: "It's increasingly being recognised 
that employers have an opportunity to provide options for staff to become more 
active during the working day.

"In principle this is a good idea, and relatively inexpensive. If used 
regularly not only would individuals benefit, but employers would see reduced 
absenteeism and improved performance and job satisfaction.

"However, it's not for everyone and I was concerned that, not surprisingly, use 
of the pedal machine decreased gradually over the one month trial period as 
enthusiasm waned."
