Abstract

Protein is found all throughout the body and is the key component to building muscle. Protein is built from building blocks called amino acids. It has been found that whey protein is digested very quickly, and possesses a greater compliment of essential amino acids and branched chain amino acids. Oscar Mayer P3 pack contains cheese, nuts, and meat which complement the essential amino acids. Research has shown that Whey protein stimulates greater increase in muscular strength due to its concentration, fast digestion, and mixture of peptides over its predecessors. The aim of the experiment is to determine whether powder protein will produce a higher one repetition max in bench, squat, and hand grip strength when compared to a prepackaged protein pack. Twelve men between ages 18 and 26 volunteered to participate in the study. Each subject was required to fill out a questionnaire and a consent form for risk and benefits of the study. All participants were first evaluated with a one repetition max (1RM) in bench, back squat and hand grip strength. The hand grip strength was measured by a standard Dynamometer. Participants were then divided into two groups by random. The participants met 3 times a week for 4 weeks in a recreation fitness facility for 30 minute sessions. Each session was designed to specifically address muscular strength, muscular endurance, and aerobic capacity. After 4 weeks a measure of the 1RM in bench, squat, and hand grip strength was administered to determine the change of each individual. The groups were then compared to determine the effectiveness of each protein. In the independent t-test comparing the pretest and posttest of the whey protein group and P3 group bench max had no significant difference (p >.05). The grip strength pretest and posttest max had no significant difference (p >.05). The squat strength pretest and posttest max had no significant difference (p >.05). In the dependent t-test comparing the two groups of the whey protein and the P3 group significant differences (p<.05) were found between the two groups. In bench, squat, and grip strength there was a significant difference between the pretest and posttest. The present study found evidence that consuming additional protein during resistance training will result in strength gain in untrained males. This will be attributed to the extra dietary protein or the neural adaptations.
