The Research On High-level University Sprinter's Dietary And Nutrition Of Hunan Provinic

Purpose:The basic dietary balance and use of nutritional supplements for athletes in a scientific and efficient way have become an increasingly concerned issue by sports and medical industry in China. There is no doubt that athletes can restore from tiredness and maintain good body status by balancing diet and taking nutritional supplements under proper guidance. Many investigations have shown that imbalanced diet and un-guided intake of nutritional supplements have little effect on helping athletes'body restoration. This paper has investigated the problems existed in the basic diet by providing nutritional KAP questionnaire to high-level university athletes in Hunan and using a 24-hours retrospective analysis on the athlete's daily routine diet and additional diet.Methods:Nutritional KAP questionnaire and conducting 24-hour retrospective analysis has been provided to 32 sprinters in the Central South University, Hunan University, Hunan Normal University, Xiangtan University, Changsha University of Technology, Central South University of Forestry and Technology, which have recognized qualification of recruiting high-level athletes by Education Ministry of China. The feedback from the abovementioned Sprinters are used as the data source in this research paper.Results:(1)The statistical analysis of KAP questionnaire feedback shows that the sprinters are typically lack of basic knowledge on fundamental and special nutrition.(2)Most of sprinters has good nutritional status. (3) Though the sprinters have good nutritional status, local strong-flavour eating habit in Hunan is not good for their nutritional absorption. (4) The composition of basic diet was inappropriate. (5)The intake of three major sources of energy for the sprinters is inappropriate. The in-take of fat and protein is higher than the recommended level and the in-take of carbon-hydrate is in line with recommended level. The excessive in-take leads to extra burden for metabolism.(6) The ratio of energy generation from daily diet is inappropriate. (7) Coaches and sprinters are not familiar with the working mechanism, usage and the physiological signs of the nutritional supplements commonly used.Conclusions:(1) The athlete team of universities in Hunan shall enhance its role in the management and intervention of athlete's diet and offer the guidance of proper diet to athletes. (2) It is necessary to enhance the guidance on the athletes for understanding basic nutritional knowledge and specialized nutritional knowledge, and make them recognise the important benefits of balanced nutritional diet to muscle cell function and to body restoration. (3) The match of personal training needs with light-flavoured foods are recommended, which will be helpful in the nutritional absorption for athletes. (4) It is necessary to make athletes aware of the function, usage and physiological signs of different nutritional supplements. Professional guidance for athletes on in-take of nutritional supplements will maximize its positive effects. (5) Attention should be paid to athlete's in-take of protein during winter training, which will ensure the nutritional sufficiency and body restoration after training. (6) Athletes should be made aware of the physiological signs, usage, dosage and in-take times of creatine.
