*V̇*_{O2max},maximal oxygen consumption in exercise; *V̇*_{O2sum}, maximal oxygen consumption in thermogenesis.

Regressions were performed on animals younger and older than the`breakpoint' age of 485 days determined from the complete data set. Regression coefficients (*r*) and *P* values for fat and lean tissue content were computed from absolute tissue mass and as fractions of whole body mass; in the latter case, regressions also included whole body mass(*r* and *P* values not shown). No *P* value is significant after Bonferroni correction (adjusted α=0.0023 for young and old mice).
