First two strides of acceleration sprinting consist of which phases?

• A. Support and Flight phase
• B. Drive and Float
• C. Impact and Recovery
• D. Collision and Release

Answer: (A)

In sprinting, a stride has two main phases: the foot is in contact with the ground (support) and the foot is off the ground (flight) between contacts. During the first steps of acceleration, you spend time pushing off the ground to generate forward force (support) and then briefly time in the air before the next contact (flight). This alternating pattern—ground contact (support) followed by a period airborne (flight)—is why the first two strides of acceleration consist of Support and Flight. The other labels aren’t the standard way this rhythm is described in sprint mechanics, so they don’t fit as naturally with how acceleration starts and how force is applied through the stride.
