Objective:The Balanced Nutrition is based for healthy, only the combination of a reasonable nutrition and scientific training can help to improve the exercise performance. At present, some scholars survey the nutritional status of athletes through the dietary investigation, but the improve processes and the situation after improved were studied less. I made a systematic analysis for the male rowing athletes, finding reasonable intervention means. After the intervention I did the dietary survey and biochemical testing again, aim to observe the effect of athletes improved nutrition.Methods:The research object is ten male open class rowing athletes in Anhui province. First,I used nutritional KAP survey to find athletes dietary behavior and nutrition knowledge, then recorded intakes of each food in three day by dietary weighing method, through the software analysis, at the same time the blood biochemical indexes be tested by the hospital. After four weeks of intervention, I used dietary survey and biochemical testing again. Finally, I used statistical methods to process and analysis the former and the improved data.Results:Through the nutritional KAP survey found that most of the players lacking basic nutrition knowledge, existing unhealthy eating behaviors. But they have good attitude, willingness to accept more nutrition knowledge and correct poor eating habits;the results of dietary investigation:after the intervention intake of breakfast and lunch increased, dinner uptake was significantly reduced; Nutrients intake: after the intervention, the intake of protein, carbohydrate increased, fat decreased significantly; Vitamins intake, after intervention, VA,VB1, VB2 took increased; kinds of food intake, after the intervention, the intake of cereals, vegetables, milk increased significantly, edible oils were significantly reduced, meat reduced and aquatic intake has increased, but had no significant difference; Changes in blood parameters:after the intervention blood parameters occurred a benign change. After exercise blood glucose has slightly higher than before. TC, TG, LDL-C were lower than before, HDL-C was higher. Conclusion:1. Through the nutritional KAP survey found that most of the players think the reasonable diet is very important, but they lacked basic nutrition knowledge, existing unhealthy eating behaviors,which is one of reasons for dietary unbalanced.2. The survey found before intervention most of the athletesl’dietary structure is unreasonable, the intake of nutrients is not equilibrium; through four-week dietary intervention, achieved certain effect, dietary structure and the intake of nutrients are more rationalization.3. After the dietary intervention, blood lipid metabolism index also has certain good changes, it is helpful for maintaining the balance of blood lipid metabolism for athletes
