determined by asking the subjects to rate this on a 20 point continuous scale from
“Not at all alike” to “Exactly the same”.
RESULTS
Table 1 shows the VO2 of the subjects finning on the ergometer at heart rates to match
those predicted for finning in open water at 0.7 and 1.1 kts. The heart rates and VO2
values are mean values for each subject calculated from data collected during the final
five minutes of exercise at the two simulated velocities.

The mean (SD) rating of how closely finning on the ergometer corresponded with
finning in open water was 15.8 (2.1) and the divers stated that the only difference was
that they could not roll their shoulders on the ergometer as they would when finning
in open water. A further study indicated that the kinematics of finning on the
ergometer were the same as in open water (Pisula et al, 2007). Finning VO2 peak and
running VO2max are shown in Table 2.
