Inadequate nutrition can significantly impair athletic performance by depriving the body of essential nutrients necessary for energy, recovery, and muscle repair. A lack of adequate calories and nutrients, such as proteins, vitamins, and minerals, can lead to fatigue, decreased strength, and increased injury risk. Moreover, poor nutrition can affect mental focus and concentration during performance, hindering athletic potential. To optimize performance, athletes must ensure they consume a balanced diet meeting their individual energy and nutrition needs.
