Which statement best summarizes maximum velocity sprinting technique?

• A. Shoulders are steady, elbows at 90 degrees, and hands cupped; mouth open; jaw sag; flight 0.12-0.14 s; push-off ~50-55 degrees
• B. Shoulders should hunch forward; elbows extended; hands clenched; mouth closed; long flight
• C. Shoulders relaxed; elbows at 0 degrees; hands flat; mouth open; flight phase absent
• D. Shoulders rotated; elbows at 120 degrees; hands interlaced; jaw clenched; no flight phase

Answer: (A)

Maximum velocity sprinting relies on an efficient, stable upper body and a compact, powerful arm drive that keeps the torso aligned and energy moving forward. The best statement captures that by keeping the shoulders steady, the elbows at about 90 degrees to allow quick, efficient arm swings, and the hands cupped to reduce drag while the mouth is open and the jaw relaxed to enable easy breathing and minimize tension. A brief flight phase around 0.12–0.14 seconds and a push-off of roughly 50–55 degrees align with the rapid, forceful propulsive action needed for top speed. In contrast, hunching the shoulders, extending the elbows, clenched hands, or a closed mouth disrupts posture or breathing; a long or absent flight phase indicates slower movement; and rotated or overly large elbow angles with tense jaw create inefficient mechanics that hamper maximum velocity.
