Injury Prevention of Young Adult Competitive Athletes Abstract: This literature review covers many aspects of health and injury prevention that affects the young adult population. This review will begin to formulate a general guideline for sustaining performance while minimizing the incidence for injury. This population is specifically narrowed down to competitive athletes between the ages of 16-22. Some of the topics covered in this paper are the effects of macro-nutrients and micro-nutrients such as iron, calcium, vitamin D and vitamin C, on the body. Along with relating nutrition to lowering the risk of injury, there are also other topics covered such as sleep, stress relief in the form of binaural sounds, training and over-training. Nutrition topics include carbohydrates, proteins and fats, which are then split into their respective roles inside the body. These macro-nutrients are also associated with recovery and the timing and quantity consumed can be at optimal levels for competitive athletes based on gender, age and size. The vitamins and minerals discussed are also important factors in injury prevention related to bone, ligament and muscle strength. These micro-nutrients are also related to hormone regulation and immune system response which are necessary in mitigating the risk of injury in the population being analyzed. Finally, there is a training section of this literary review which covers monitoring external and internal loads experienced by the athletes, movement patterns as well as flexibility, and how to respond to over-training syndrome and overreaching in young adult athletes. Creating a balance between all aspects covered will result in a high likelihood of reducing the risk for injury in the young adult population.
