Summary dose–response relationship between MPS and AA feeding (±RE) in older women (including data from Bukhari et al. [27]). Over 0–2 h, feeding increased MPS with little enhancement with RE (A). Over the entire 4 h (B) postprandial measurement period, MPS was elevated although diminished with feeding, whilst RE sustained elevated MPS. All groups displayed similar MPS in response to feeding (±resistance exercise) suggesting only a small dose of leucine and/or EAA are required in combination with exercise to maintain elevations in MPS post nutrition, at least over the first 4 h. Left Y axis shows FSR for each feed (open circles FED, open squares FED + RE) whilst dotted lines show average FSR of all groups for baseline, FED and FED + RE. Right Y axis shows total AA load and content of leucine, EAA and NEAA.
