Why is horizontal force important for sprinting?

In acceleration, the ability to apply force horizontally relative to the ground (rather than vertically) is the primary determinant of acceleration performance and is more trainable than vertical force.

How is sprint force estimated without force plates?

Using the inverse dynamics approach of Morin et al., horizontal force can be estimated from split times and body mass, allowing field-based assessment without laboratory equipment.

What ratio of horizontal to vertical force is ideal?

The mechanical effectiveness index (ratio of horizontal to total force) typically ranges from 0.35 to 0.55. Elite sprinters show ratios above 0.50 during peak acceleration.
