Why hyperventilation is useful before short distance run?

Hyperventilation before a short-distance run can help increase oxygen availability in the bloodstream and reduce carbon dioxide levels, potentially enhancing performance. By rapidly breathing, athletes may feel a temporary boost in energy and reduced fatigue. However, this technique should be used cautiously, as it can lead to dizziness or lightheadedness. Overall, it may provide a quick physiological adaptation, but it's not universally recommended for all athletes.
