Definition

Efficient sprint form is tall and braced with high front-side knee drive, dorsiflexed feet, ground contact under the hips, and a powerful shoulder-driven arm swing.

Detail

Good running/sprint form maximizes useful force and minimizes braking. Core elements:

Posture: tall spine, braced trunk, neutral head/gaze; a slight whole-body forward lean from the ankles at top speed (a pronounced lean only during acceleration). Avoid sitting/"running tall but hips dropped."
Front-side mechanics: drive the knee up and forward (thigh toward parallel), keeping action in front of the body rather than excessive heel recovery behind ("back-side"). High knee drive sets up a powerful downward strike.
Foot strike: land on the ball of the foot under or just behind the hips with a stiff, dorsiflexed ("toes-up") ankle; minimize ground-contact time at speed. Landing far ahead of the hips (over-striding) is a braking error.
Recovery: as the foot leaves, the heel recovers quickly toward the glute and the knee swings through ("step over the opposite knee").
Arm action: drive from the shoulders, elbows ~90°, hands traveling roughly cheek-to-pocket, relaxed hands/face; arms move opposite the legs and contribute to frequency and balance.
Relaxation: keep the face, jaw, and shoulders relaxed; tension wastes energy.

Form is taught with sprint-form drills (A-skips, B-skips, high knees, butt kicks, dribbles) that isolate dorsiflexion, knee drive, front-side mechanics, and rhythm before/within sprinting.

Key facts

Tall braced posture; slight ankle-based lean at speed (big lean only in acceleration).
High front-side knee drive; quick heel recovery; "step over" the opposite knee.
Dorsiflexed foot striking under/just behind the hips; short contact; no over-striding.
Arms drive from the shoulders, ~90° elbows, cheek-to-pocket, opposite the legs.
Stay relaxed (face/shoulders/hands).

Connections

Sprint Mechanics — form serves the two sprint phases.
A-Skip — drills dorsiflexion, knee drive, and front-side rhythm.
High Knees — reinforces knee drive and posture.
Butt Kicks — drills quick heel recovery.
Tibialis Anterior — maintains dorsiflexion ("toes up").
