Many researchers have found that taking protein supplements before and after strength training can increase the rate of muscle protein synthesis.
However, few people have delved into the impact of this phenomenon on changes in strength and body composition. Jay Huffman and his colleagues at the State University of New Jersey found in a ten-week study that whether and when protein supplements were used had an impact on subjects' absolute strength, power, and strength. Body composition had no effect.
In this trial, subjects were asked to take protein supplements in the morning and evening; take protein supplements before and immediately after strength training; or not take protein supplements at all, and other Any nutritional supplements. Moreover, the subjects used in this study were all people who had been strength training for a long time.
