Individual identification was entered as a random factor to control for repeated measurements.
The 2002 values are the mean values of measurements 3 and 4 in April/May 2002, while the 2004 values are the mean values of both measurements in April/November 2004.
For comparison, we report the mean values of body mass and V̇O2 (ml O2 h-1 as well as ml O2 g-1h-1) for each sex in 2002 and 2004.
