Exercise improves fat metabolism in muscle but does not increase 24-h fat oxidation

Exerc Sport Sci Rev. 2009 Apr;37(2):93-101. doi: 10.1097/JES.0b013e31819c2f0b.

Abstract

Despite decades of research into the effects of exercise on fat metabolism, there is still no clear understanding of how exercise helps to regulate fat mass. Although exercise improves the capacity of muscle to oxidize fat, our studies suggest that moderate duration exercise (< or =1 h) has little impact on 24-h fat oxidation.
