Research On Nutrition Support For Physical Fitness In Young Basketball Athletes

Basketball players need a higher demanding for better physical fitness to meet the tremendous development of basketball. Besides scientific training, nutritional support is also an important aspect to improve basketball players' physical fitness. Nutritional support has not been applied in basketball for a long time because lack of necessary recognition, theory support and case study.This research, by combining the method of theoretical study with experimental study, investigated and systematically analyzed the elite youth basketball players' nutritional status in China, and put forward a fundamental theory on nutritional support. In addition, we also adopted nutritional intervention test to study its effects on youth basketball players' physical fitness.In part 1, current nutrition studies in basketball game were summarized and analyzed, which stressed that it is necessary and emergent to study sport nutrition in basketball. The importance of physical fitness in sports and the relationship between sports nutrition and physical fitness demonstrates that sport nutrition plays an important role in physical fitness; basketball needs nutrition and the character of nutritional compensation.In part 2, we discussed, from theoretical point, the avenue of nutritional support to basketball players' physical fitness in China. According to the traits of basketball, we analyzed the relationship between basketball and nutrition; basketball players' nutritional avenues, mechanism and implemental principle, and finally, pointed out the significant role of these above factors played in improving players' physical fitness.In part 3, by analyzing the nutritional status of one of the Chinese youth basketball teams, we found many problems, such as lack of their nutrition knowledge, mal-nutrition of the unscientific nutrition structure in diet and drinks, common deficient scientific monitoring and control. These findings suggested that basketball sport beverage is in an urgent need.In part 4 and 5. we prescribed a kind of nutritional liquid which was specially designed for basketball players, and was administrated to the Chinese youth basketball teams as a nutritional interference test. The results by analyzing the change of Hb, LDH, CK, serum immunoglobulin G and A, serum testerone and cortisol in the youth basketball players, we found that nutritional support decreased serum cortisel without change of testerone, and thus increased the ratio of testerone to cortisol, which could impress the stress reaction in the athletes.In part 6, by observing response of hematological iron status to the above nutritional liquid in the basketball players', we found that these basketball players had no sign of anemia, but comparatively insufficient of serum iron during the training which could be against by the nutritional iron supplementation. A hyper-responsibility of the erythropoiesis to iron supplementation could be appeared.In part 7, through summarizing the present research, we suggest that nutritional support will be one of the important keys to improve basketball players' physical fitness, and it is currently necessary to establish a chain from training of physical fitness, to evaluation system of the nutritional support and to exercise medicine. The two latter aspects should be pertinent to the specific physical fitness of the basketball sport.Conclusion: The basketball players' physical fitness wants nutritional support; the nutritional status and nutritional support of Chinese basketball players' term is currently under-concerned; basketball players' nutritional intervention can deal with the decrease of blood glucose and serum iron; by nutritional intervening basketball player, we can solve some problems as fatigue, injury, immunization-improvement, increase energy and improve hormone function; basketball players' nutritional intervention can also lower the response of cortisol to movement, so as to ameliorate the stress respoase.This thesis, for the first time, puts forward the importance, necessity and availability of special nutrition to basketball players, by nutritional intervening youth basketball players in China. A nutritional intervention can enhance basketball players' physical fitness; intake more carbonic acid drinks will induce calcium loss among basketball players, and increase the possibility of basketball players' catagma. The findings from this research are of great value both to supporting basketball players' physical fitness training and to expanding basketball theory.
