Increased nutritional needs for general and competitive athletes
Scientific studies frequently show nutritional deficiencies among athletes . Often , they receive inadequate supplies of vitamins and minerals , for instance ( too little fruit , vegetables , greens , and whole grain products ). In addition , athletes can suffer due to individual life circumstances such as a lack of time or travelling , smoking , consuming alcohol , or even training schedules and competitions for competitive athletes .
General athletes suffer nutritional deficiencies more frequently than top athletes , since their bodies are less welladapted to the high levels of performance demanded of them . They can suffer increased electrolyte and fluid loss more quickly . Possible consequences include : poorer performance and less energy , greater susceptibility to injuries , more fatigue , slower recovery times after athletic endeavours or a weakened immune system .
