Abstract(s)
Potassium (K+) is a critical alkali metal and the most abundant cation in the body, primarily found inside cells. It's measurable in serum, plasma, whole blood, and urine. During intense exercise, potassium is released from muscles into the bloodstream, with levels related to exercise intensity. Potassium is essential for cell polarization and transmitting electrical impulses in the heart, so fluctuations in serum potassium (hypokalemia or hyperkalemia) can lead to life-threatening arrhythmias and myocardial issues in athletes. Hypokalemia, or low potassium, can cause muscle issues and, in severe cases, cardiorespiratory arrest due to losses through urine, sweat, or the gastrointestinal tract. Hyperkalemia, or high potassium, may result from excessive intake or kidney problems, causing muscle cramps and reduced excitability, affecting athletic performance. Athletes balance fatigue and recovery, with potassium fluctuations being crucial to their limits. The line between beneficial and harmful effects is fine, and maintaining a diet rich in potassium-regulating foods is vital to prevent imbalances. Understanding potassium's role in intense physical activity helps optimize performance and avoid health risks. The main goal of this systematic review is to compare the blood potassium levels obtained before and after training in athletes.
