Potassium plays a crucial role in muscle function by supporting proper muscle contraction and nerve signaling. This essential mineral helps maintain electrolyte balance, facilitating muscle contractions during physical activities. Adequate potassium levels prevent muscle cramps and strengthening the heart's rhythmic contractions, contributing to overall cardiovascular health. Foods rich in potassium, like bananas, oranges, and spinach, should be included in the diet to ensure optimal muscle performance and recovery. Maintaining sufficient potassium is essential for athletes and anyone engaged in regular physical activity.
