Det har varit känt länge att träning, oavsett typ eller intensitet, inte ökar fettförbränningen.

The increased energy demand is met by increased carbohydrate oxidation, with no increase in 24-hour fat oxidation.
Strength Cond Res. 2005 Feb;19(1):61-6.

Similarly, the differences in HI and LI exercise, RQ are compensated postexercise leading to similar substrate oxidation patterns over 24 h independently of the level of exercise intensity.
Int J Obes Relat Metab Disord. 2004 Jun;28(6):759-65.

In men, resistance exercise has a similar effect on 24-h EE and macronutrient oxidation as a comparable bout of aerobic exercise. Neither exercise produced an increase in 24-h fat oxidation above that observed on a nonexercise control day.
Med Sci Sports Exerc. 2002 Nov;34(11):1793-800.

Both 24-h EE and carbohydrate oxidation were significantly elevated on the exercise days (Con < LI = HI), but 24-h fat oxidation was not different across conditions. Muscle enzymatic profile was not consistently related to 24-h fat or carbohydrate oxidation. It is concluded that exercise intensity has no effect on 24-h EE or nutrient oxidation.
J Appl Physiol. 2002 Mar;92(3):1045-52.

These findings demonstrated higher 24-h EE in the HI than LI protocol, but similar 24-h substrate oxidation rates.
Med Sci Sports Exerc. 1996 Sep;28(9):1138-43.

The changes in 24 h substrate utilization in the obese, as well as in the well-trained group, suggest that endurance training increased the reliance on carbohydrate oxidation and therefore did not increase 24 fat oxidation.
