How can the principle of overload be applied to a sport, such as tennis or basketball?

Answer:

In tennis, a player could gradually add more time to practice or perform faster, more demanding footwork and rally drills. In basketball, a player could add more high-intensity court sprints or increase the length of skill-drill sessions. These activities challenge the body more than its usual workload, and the increase should be gradual to allow adaptation and reduce injury risk.
