Two different studies carried out by American and Canadian researchers suggest that protein drinks can actually be effective but it depends on whether they are taken immediately.
The first study, led by Stefan Pasiakos of the U.S. Army Research Institute of Environmental Medicine, looked into the effectiveness of protein drinks containing different amounts of amino acid, with 1.87 or 3.5 grams of leucine used in the study.
AdvertisementThe second study was conducted by Stuart Phillips of McMaster University in Hamilton, Ontario, with researchers checking whether a single dose of protein drink taken immediately after workout is more effective than taking it in small doses over a period of time.
"The idea with the small 'protein shots' was to mimic how another milk protein, casein, is digested. Participants, eight men; mean age of 22, performed eight sets of eight repetitions on a leg-extension machine; each subject participated in both dietary treatment regimens", Phillips said. Both the studies have been published in The American Journal of Clinical Nutrition
