The term used for athletes sponsorship is "endorsement." This involves companies or brands providing financial support or resources to athletes in exchange for promotional opportunities, such as advertising or showcasing products. Endorsements can significantly impact an athlete’s income, helping them fund their training and living expenses while enhancing their public profile. High-profile endorsements often highlight the athlete's success and skills, creating a mutually beneficial relationship. Brands leverage athletes’ visibility and fan base to reach wider audiences, while athletes gain the support needed to excel in their respective sports, benefiting both parties in the process.
