An athlete earns a living from competing and training in a sport. That athlete is a professional. Payment may come from salaries, prize money, sponsorships, or a combination.

Professional status brings higher training standards, greater public scrutiny, and the pressure of performance tied to livelihood. Contracts, agents, and collective bargaining shape working conditions in team sports. Individual sports rely more on rankings, appearance fees, and endorsements.

The boundary between amateur and professional has shifted over time; many Olympic sports now allow professional participation. Supporting roles—coaching, medicine, analysis—have also professionalized. For the athletes themselves, professionalism demands consistent high-level output across a long season or circuit.
