Silk peptides boost stamina, oxygen uptake and fat burning
Right now silk peptides are mainly found in cosmetics, but sooner or later you'll start coming across them in sports supplements. At least, that's our prediction. We've been reading Asian studies on silk peptides, and we're impressed: they boost fat burning, oxygen uptake and improve endurance capacity during rest and exertion.
Silk peptides
Asians have been eating the proteins from these cocoons, or cut-up versions of them, for centuries, and in South Korea scientists at Konkuk University have been studying whether silk-peptide supplements can improve athletes' performance. One of their discoveries is that mice swim for longer if they are given silk peptides, and that supplementation prevents their testosterone levels from dropping as a result of the exertion. [Biol Pharm Bull. 2010;33(2):273-8.] In 2013 they published a study in which silk peptides boosted fat burning during periods of rest and during periods of exertion. [J Nutr Sci Vitaminol (Tokyo). 2013;59(3):250-5.]
VO2 max, fat burning
Supplementation boosted the animals' oxygen uptake capacity.
In addition, the animals burned more fat during a 60-minute running session after two weeks of supplementation plus training than the mice in the control group did. The figure above shows this. The figure below shows that silk peptides boosted fat burning throughout the whole session.
