Abstract
Summary And Conclusions
The gaseous exchange during exercise was studied in 10 dugs starved for 5 to 15 days. The average of 16 respiratory quotients of the muscles of the lower extremities obtained by analysis of the blood was .81 ± .05. Eight respiratory quotients obtained from the air during rest yielded an average of .82 ± .04. Sixteen air samples collected from exercising dogs gave an average of .82 ± .07.
The respiratory quotient of the exercising muscle in situ is not unity. This indicates that not only carbohydrate foodstuffs but also non-carbohydrate are used in muscular exercise.
