AMHERST — A recent pilot study by kinesiologists at UMass Amherst found that pedaling while conducting work tasks improved insulin responses to a test meal. Investigators led by Dr. Stuart Chipkin found that insulin levels following the meal were lower when sedentary workers used a pedal desk compared to a standard desk. In addition, work skills were not decreased in the pedaling condition.

Chipkin and colleagues concluded that pedal desks “could have the potential to achieve public and occupational health goals in sedentary work environments.” They pointed out that physical inactivity and sedentary work environments have been linked to higher rates of obesity, diabetes, and heart disease through insulin resistance and other mechanisms. Results appear in the October issue of Medicine & Science in Sports & Exercise.

Chipkin, an endocrinologist who studies the impact of physical activity and medications on insulin sensitivity and skeletal muscle metabolism at UMass Amherst’s School of Public Health and Health Sciences, explained that, instead of approaching the problem by trying to squeeze intermittent activity into a largely sedentary work routine, “we chose to consider integrating physical activity into the workday.”

He and colleagues felt that the alternatives now available for office workers — standing desks and treadmill desks — are not feasible to use for whole shifts and may even pose some barriers, such as standing too long. By contrast, a pedal desk can be used in a seated position at the user’s own pace for as little or as much time as the worker chooses. 

Though there are currently no commercial pedal desks on the market, Chipkin and colleagues were able to use a prototype Pennington Pedal Desk co-invented by UMass Amherst kinesiology researcher Catrine Tudor-Locke, a co-author who did not determine study design or have any contact with participants or study data.

For this work, the researchers recruited 12 overweight or obese full-time sedentary office workers — six men and six women — and tested them in two conditions, pedaling at self-selected light-intensity pace for two hours, and working while seated for two hours at a conventional desk. In both conditions, participants performed computer-based tasks and were tested on mouse proficiency, typing speed and accuracy, reading comprehension, and concentration/attention.

The participants also provided blood samples after eating a light meal for analysis of metabolic responses of glucose, insulin, and free fatty acids, a link between obesity, insulin resistance, and type 2 diabetes.

Chipkin and colleagues reported that pedal-desk use required significantly less insulin to maintain glucose concentrations compared with using the standard desk. “It took much less insulin to keep their blood sugars the same,” he noted. “This means that the body doesn’t work so hard to maintain blood glucose and fatty-acid levels with use of the pedal desk compared to a standard desk. From the metabolic point of view, the pedal desk seems to be helpful, and from the work point of view, work tasks were not impaired.”

He added that, “while there were no changes in blood glucose or free fatty acids, none would be expected in a group of subjects without diabetes.” In future studies, Chipkin plans to explore the impact of the pedal desk on people with diabetes. 

This work was supported by a grant from the National Institute of Occupational Safety and Health to UMass Lowell, which in turn awarded study funds to the UMass Amherst research team. Chipkin said he and colleagues would next like to conduct a larger, longer-term study, perhaps in a real-world setting where half the office staff use a pedal desk and half use a conventional desk.

NORTHAMPTON — Girls on the Run (GOTR) of Western MA will host its 5K celebration on Sunday, Nov. 18 at 10:30 a.m. at Smith College.

Girls on the Run is a positive, physical-activity-based youth-development program that uses fun running games and dynamic discussions to teach life skills to girls in third to eighth grade. During the 10-week program, girls participate in lessons that foster confidence, build peer connections, and encourage community service while they prepare for an end-of-season celebratory 5K event.

Participation in the 5K event on Nov. 18 is open to the public. About 500 girls and 150 volunteer coaches are participating in the program this season, and more than 1,200 participants are expected at the 5K. Pre-registration cost is $20 for adults and $10 for children, and includes a GOTR 5K event shirt. The event will begin on the athletic fields off Tennis Court Drive, and will go through the campus.

Registration is open at www.girlsontherunwesternma.org. Registration will also be available the day of the event beginning at 9 a.m., for a cost of $30. The run will begin at 10:30 a.m., but festivities including a group warm-up and games will begin at 10 a.m. Early arrival is suggested.
