Lika stor muskeltillväxt av sojaprotein som av vassleprotein

[King Grub]

Much attention has been given to determining the influence of total protein intake and protein source on gains in lean body mass (LBM) and strength in response to resistance exercise training (RET). Acute studies indicate that whey protein, likely related to its higher leucine content, stimulates muscle protein synthesis (MPS) to a greater extent than proteins such as soy and casein. Less clear is the extent to which the type of protein supplemented impacts strength and LBM in longer term studies (≥6 weeks). Therefore, a meta-analysis was conducted to compare the effect of supplementation with soy protein to animal protein supplementation on strength and LBM in response to RET. Nine studies involving 266 participants suitable for inclusion in the meta-analysis were identified. Five studies compared whey with soy protein and four compared soy protein with other proteins (beef, milk or dairy protein). Meta-analysis showed that supplementing RET with whey or soy protein resulted in significant increases in strength but found no difference between groups (bench press Chi2 = 0.02, p=0.90; squat Chi2=0.22, p =0.64). There was no significant effect of whey or soy alone (n=5) on LBM change, and no differences between groups (Chi2=0.00, p=0.96). Strength and LBM both increased significantly in the 'other protein' and the soy groups (n=9), but there were no between group differences (bench Chi2=0.02, p=0.88; squat Chi2=0.78, p=0.38 and LBM Chi2=0.06, p=0.80). The results of this meta-analysis indicate that soy protein supplementation produces similar gains in strength and LBM in response to RET as whey protein.

Hade det här varit för fem år sedan hade det varit ett jävla liv på Jacob nu

Men kontrollerade dem så att båda grupperna fick i sig lika mycket protein över hela dagen med eller bara vilket tillskott de valde?

Det här är ingen studie utan en metaanalys.
