Abstract

This study aimed to describe the effect of Whey protein on health, delay fatigue, and improve the performance of long-distance swimmers.
Materials and methods: Using the experimental method of pre-post analysis. We chose (14) long-distance swimmers for the study. We treated whey protein for two months at a dose level of 1.6 grams/kg b.w, where we collected blood samples in centrifuge tubes before and after Whey protein ingestion at rest. This was after an 800meter swim to detect immunoglobulins (IgG, IgA, IgM), SoD, glutathione reductase, Malondialdehyde together with LD, creatine kinase, Na+ and prolactin, and Wbcs. The results indicated that high antioxidants and immunoglobulin were remarkable. And a decreased Malondialdehyde after Whey protein administration, lactate dehydrogenase (LD), creatine kinase, and Na+ decreased after Whey protein ingestion.
Conclusion: Whey protein induced several benefits as it showed improvement in immunity, delayed fatigue, and also improved physical performance and score level of long-distance swimmers.
