The study was conducted to check if there is any variation in muscle strength and fatigability in people who gym consuming whey protein (supplement) in comparison to those consuming meat, fish and eggs. Participants were divided into two groups: Group A with whey protein consumers and Group B with normal diet consumers. BMI was calculated both the type of the consumer and Muscle strength was measured with the help of hand grip dynamometer and fatigability with Mosso’sergogram. The results came out to be inconclusive showing no significant variation in terms of strength and fatigability in the two groups. Because of the same time the group were not formed and gym time were quite different. Now The questions follow that can a better result be obtained if the time period in gym of each group was same? Study of Effects on Potency And Fatigability Of Muscle Develop In People Who Gym Consuming Whey Protein (Supplement) With Compared To Consuming Meat, Fish And Eggs (Natural Protein) Based on the results obtained, the research is inconclusive, and was unable to find any significant variation in terms of strength and fatigability in whey protein consumers and normal diet consumers. Further research in terms of selecting individual participants who would start the gym at the same time and then form a part of the two groups of whey protein consumers and normal diet consumers, allowing equal amount of gym time would be able to interpret the result more appropriately.
