Protein from potatoes stimulates muscle growth
Study
The women in the experimental group received the same amount of protein through their regular diet. But they also ate a pudding twice a day that contained 25 grams of potato protein. So throughout the day the women consumed 50 grams of potato protein. In total, these women consumed 1.6 grams of protein per kilogram of body weight daily. [PP]
The potato protein that the researchers used is on the market as Solanic. [Link] Solanic is a product of Avebe, a Dutch company. [avebe.nl]
Potato protein has a particularly high viscosity, and is therefore not suitable for making shakes. They become too viscous. Therefore, the researchers used pudding.
The women in the control group received placebo pudding without potato protein.
The researchers had the women train one of their legs on a leg extension and a leg press machine 3 times a week. The women trained lightly, with 30 percent of the load with which they could just make 1 rep.
The researchers measured how much protein the women's leg muscles made before they got pudding and before they trained [Baseline], after they got pudding but didn't train yet [Rest], and after they got pudding and trained [Exercise].
Results
Conclusion
"Our findings highlight that potato protein is effective in stimulating rates of muscle protein synthesis with supplementation alone and that this effect is enhanced when feeding with potato protein isolate is combined with resistance exercise."
Sponsor
But it is a sponsored study, we must confess. The researchers were funded by the Alliance for Potato Research & Education, [apre.org] "a not-for-profit organization funded by the potato industry, including potato growers and potato food manufacturers".
Would there ever be a study comparing the effect of good old whey with that of potato protein?
