No: Polycythemia (increased red cells in the blood) will not make him a better athlete. Within limits, it increases the oxygen deliverable by blood and may improve endurance. Elite endurance athletes sometimes train in lower oxygen (e.g. At altitude) to induce a form of polycythemia. This is not advised for children. Polycythemia should be evaluated as it can be dangerous and signal serious disease.
