How much potassium do athletes need?

The general adult recommendation is 3,500-4,700 mg/day. Athletes who sweat heavily may need 4,000-5,000 mg/day. Sweat potassium concentration averages 150-200 mg/L, so heavy sweaters lose 300-600 mg/hour.

Does potassium deficiency cause muscle cramps?

Severe potassium deficiency can contribute to cramping, but exercise-associated cramps are more commonly caused by neuromuscular fatigue than electrolyte imbalance in well-nourished athletes.

What foods are high in potassium?

Bananas (422 mg per medium banana), potatoes (926 mg per medium), avocado (975 mg per fruit), salmon (628 mg per 3 oz), and spinach (839 mg per cup cooked) are excellent sources for athletes.
