The link is physreports.physiology.org/content/physreports/4/15/e12893.full.pdf

Contradicts a lot of common advice but goes along the lines of what we talk about here

I just read the abstract so maybe it says it somewhere, but how long after resistance training do they ingest the protein?

shouldve compared 20g followed by another 20g later vs 40g in 1 shot, basically it says ur body creates more protein if u eat more protein

Weak study, only 30 participants, no mention of controlling confounders, and huge error bars in almost all their graphs....

Take this one with a grain of salt boys and girls.

they did a standardized job of controlling for things, such as diet and activity, that might influence MPS, 30 participants is a big sample size for a biopsy study using 6 bergstrom samples from each subject, and those are confidence intervals not error bars

e: regardless, my original point was that nutritional research cant even agree with itself

The currently accepted amount of protein required to achieve maximal stimu- lation of myofibrillar protein synthesis (MPS) following resistance exercise is 20–25 g. However, the influence of lean body mass (LBM) on the response of MPS to protein ingestion is unclear. Our aim was to assess the influence of LBM, both total and the amount activated during exercise, on the maximal response of MPS to ingestion of 20 or 40 g of whey protein following a bout of whole-body resistance exercise. Resistance-trained males were assigned to a group with lower LBM (≤65 kg; LLBM n = 15) or higher LBM (≥70 kg; HLBM n = 15) and participated in two trials in random order. MPS was mea- sured with the infusion of 13C6-phenylalanine tracer and collection of muscle biopsies following ingestion of either 20 or 40 g protein during recovery from a single bout of whole-body resistance exercise. A similar response of MPS during exercise recovery was observed between LBM groups following protein ingestion (20 g – LLBM: 0.048 ` 0.018% h 1; HLBM: 0.051 ` 0.014% h 1; 40 g – LLBM: 0.059 ` 0.021% h 1; HLBM: 0.059 ` 0.012% h 1). Overall (groups combined), MPS was stimulated to a greater extent following inges- tion of 40 g (0.059 ` 0.020% h 1) compared with 20 g (0.049 ` 0.020% h 1; P = 0.005) of protein. Our data indicate that ingestion of 40 g whey protein following whole-body resistance exercise stimulates a greater MPS response than 20 g in young resistance-trained men. However, with the current doses, the total amount of LBM does not seem to influence the response.
