" While the manufacturers tout the accuracy of their calorie counters, most

commercial products will likely overestimate the number of calories burned by 15

percent to 30 percent, according to Bassett, a professor at the University

of Tennessee.

Bassett and other researchers studied one of Polar's earlier calorie-counting

models, the S410, and found that on average the number of calories burned was

off by 4 percent for the 10 men tested and 12 percent for the 10 women tested.

" Measuring energy expenditure for most of us is a pipe dream. In a free-living

individual it is not possible to do, " Bassett said, adding that the current crop

of products was a good start. "
