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.
