Abstract
Sports completion is unprecedentedly intensive now and performance of athletes becomes closer and closer to limit of human’s capacity. To constantly create better performance, athletes must do a large amount of limitation training. Athletes would be found with water desorption, electrolyte loss, enhanced protein catabolism, imbalanced cell membrane penetration and enzyme escape after overloaded training and competition. Whey protein can rapidly provide athletes with water, electrolyte and energy substance, prevent excessive fatigue of athletes during sports, sustain and promote fluid balance within body and help athletes rapidly recover physical ability. Sports nutritional food is a powerful nutritional basis for athletes who engage in a large amount of overloaded training and competition. This study first discusses over the application of whey protein in the perspective of the functional characteristics of whey protein, then emphatically analyzes the impact of whey protein on physical ability recovery and fatigue elimination of canoeing athletes and finally explores the impact of whey protein on various indexes during training based on a case, thus to further confirm the action mechanism of whey protein for canoeing athletes.
Highlights
Bounous (2000) compared the antitumor effect of whey protein and casein through animal and in vitro test and found whey protein was more effective in inhibiting growth of cells of prostatic cancer, breast cancer and colon cancer compared to casein and lower the incidence rate of tumor for 50%

Summary
Bounous (2000) compared the antitumor effect of whey protein and casein through animal and in vitro test and found whey protein was more effective in inhibiting growth of cells of prostatic cancer, breast cancer and colon cancer compared to casein and lower the incidence rate of tumor for 50%. By comparing the effect of whey protein and soy protein on white mouse suffering loaded exercise, (Elia et al, 2006) found whey protein strengthened antioxidant activity through changing concentration of free radical and glutathione, while soy protein improved antioxidant activity by changing substrate concentration of thiobarbituric acid reaction. They thought taking either of them both can help body endure more intensive training. Supplementing whey protein can strengthen muscle circumference of the upper arm of canoeing athletes, promote synthesis of muscle and sustain and improve the level of testosterone (Liao et al, 2007; Mackenzie-Shalders et al, 2015). This study analyzes the effect of whey protein on physical ability recovery and fatigue relief of athletes in the aspect of action mechanism of whey protein on canoeing athletes
