Which term refers to short runs at higher speeds over shorter distances?

The term that refers to short runs at higher speeds over shorter distances is "sprints." Sprints are characterized by intense bursts of speed where individuals run as fast as possible for a limited distance. This training method helps to improve speed, power, and anaerobic fitness. Sprinters typically cover distances ranging from 60 meters to 400 meters, focusing on maximum velocity and quick acceleration.

The other terms relate to different types of running. "Interval" training involves alternating periods of high-intensity work and lower intensity or rest, which could include sprints but is not limited to them. "Base Run" refers to a longer, steady-state run aimed at building endurance and aerobic capacity, while a "Long Run" specifically denotes longer, slower runs that help develop endurance for longer distances. These distinctions are essential in understanding different training techniques and their effects on athletic performance.
