The special environment in beach volleyball playing generates intense stimulation on human bodies, which is pretty helpful in improving the performances of many sports. Meanwhile, the nutrition supply is also showing its critical significance. Due to the altitude environment, a special requirement is imposed on the calorie and nutrition supplied to the bench volleyball players in training. Therefore, the players should intake the sugar, sports drink, minerals, vitamins and some nutritional additives, correspondingly. At last, the R Weighted Mean Algorithm (RWMA) is used to analyze the data from the sample. The result shows that on the basis of the beach volleyball player’s need for nutrition, we should give the beach volleyball player meals of high carbohydrate and other nutritional supplement. And this may have some help to the improving of the beach volleyball player’s health and physical ability.
