The Effect of Vitamin Deficiency on Youth Athletes in Pathogenesis Taking Vitamin B, C, D as Examples

With the rapid development of youth sports and increasingly demanding competitive standards, scientific nutritional support has become a core strategic element in cultivating elite young athletes. However, vitamin deficiency remains prevalent among this population. This nutritional imbalance not only leads to health risks such as compromised immune function and abnormal bone development, but also directly impacts key athletic performance indicators including power output, endurance levels, and recovery efficiency. This paper examines the pathogenesis and consequences of deficiencies in Vitamin C, Vitamin B, and Vitamin D, highlighting their influence on immunity, bone health, energy metabolism. Research shows that insufficient intake not only impairs physical performance but also increases the risk of long-term injuries and illnesses, ultimately offering a theoretical foundation for optimizing dietary plans and promoting the sustainable development of youth sports.
