Fig. 3. Effect of averaging interval on maximal values of running speed (A) and
oxygen consumption (B) in 40 Mongolian gerbils during voluntary wheel running.
Broken lines indicate regressions of 2- (open circles) and 5-min averages
(filled circles) against 1-min averages (regressions were forced through the
origin). Slopes are fractions of 1-min values; for example, a slope of 0.834
indicates 83.4% of the 1-min value. The solid line shows a slope of 1.0
(equivalent x and y values).
