Stride length and frequency gradually increase during acceleration up to which values?

• A. 45 m and 35 m
• B. 40 m and 30 m
• C. 50 m and 40 m
• D. 60 m and 45 m

Answer: (A)

In sprinting, acceleration comes from two things changing together: you land longer each step (stride length) and you cycle your legs faster (stride frequency). As you push toward your top speed, both of these increase, but they don’t keep climbing forever—there’s a point where you near max velocity and the changes level off. That point typically falls around the middle of the sprint, roughly in the 40–50 meter range for many sprinters. The pair given—about aStride length of 45 m and a stride frequency of 35 m (interpreted as the progression toward that mid-acceleration mark)—best reflects reaching near-max acceleration without yet plateauing, which is why it’s the best representation among the options. The other choices imply finishing acceleration earlier or later than the typical progression, which doesn’t align with how stride length and stride rate develop during the drive phase.
