Caffeine raises fat burning after strength training
After an intensive workout the body expends extra energy. Researchers suspect that because of this, strength training can help in maintaining a healthy weight, and they are studying ways of increasing the 'after burn'. One such method is to consume caffeine before pumping iron, as sports scientists at California State University discovered.
EPOC
As far back as 1989 researchers showed that caffeine [structural formula shown below] raised the EPOC of untrained women after a cardio training session. [Eur J Appl Physiol Occup Physiol. 1989; 59(1-2): 48-54.] [Eur J Appl Physiol Occup Physiol. 1992; 65(5): 459-63.]
But does this also happen after a strength training session? And in men who are experienced strength trainers? To answer this question the researchers devised an experiment in which 14 experienced strength athletes aged between 18 and 34 took part.
Study
Results
When they took the supplement the test subjects burned 24 calories more. That's not a huge amount, in the researchers' opinion. But of course everyone is entitled to his (or her) own opinion.
