Which definition fits the concept of speed in fitness?

The definition of speed in fitness is best captured by the ability to cover distance in a short time. Speed involves how quickly an individual can move from one point to another, highlighting the efficiency and rapidity of movement. This is measured in terms of pace, typically expressed in units such as meters per second or minutes per mile, emphasizing that speed is fundamentally about the rate of movement rather than the endurance of that movement or the ability to perform multiple repetitions.

The other options refer to different concepts; for example, sustaining a steady pace relates more to endurance, while jumping distances pertains to explosive power or agility. Repeating a movement over time is associated with muscular endurance rather than speed itself. Therefore, the focus on covering distance quickly accurately reflects the definition of speed within the context of fitness.
