Javelin Technique & Hydration Science

Flashcards covering javelin technique, rules, and hydration science for athletes.

Javelin History

Hunting and warfare tool; part of Ancient Greek Olympic Games; Modern Olympic event (Men since 1908, Women since 1932).

Phases of the Javelin Throw

Run-Up, Withdrawal, Delivery, Release, Follow-Through.

Run-Up

Builds speed and rhythm (13–17 steps).

Withdrawal

Javelin pulled back behind the head.

Delivery

Lead foot plants, body rotates, arm whips forward.

Release

At 30–36° angle for maximum distance.

Follow-Through

Continue motion to stay balanced and avoid fouls.

Grip Styles

American, Finnish, Fork.

American Grip

Thumb and index grip; easy for beginners.

Finnish Grip

Held between index and middle finger; gives more power.

Fork Grip

Javelin rests between fingers like a fork; good for control.

Foul Throw Rules

Step over the foul line; javelin does not land tip-first; lands outside the sector; illegal techniques like slinging.

Equipment Specifications

Men’s: 800g, 2.6–2.7m long; Women’s: 600g, 2.2–2.3m long.

Biomechanics

Using the whole body to throw farther and stay safe. Core strength and technique help transfer power and avoid injury.

Importance of Hydration

Maintains temperature, focus, muscle function; prevents fatigue, cramps.

Dehydration Symptoms

Dry mouth/lips; dark yellow urine; dizziness or confusion; fatigue or muscle cramps.

Long-Term Effects of Dehydration

Kidney stones, UTIs, constipation, cognitive decline, hypertension, heatstroke risk.

Electrolyte Imbalance

Loss of sodium, potassium, etc., from sweat causing cramps, weakness, and heart rhythm issues.

Athletic Hydration Tips

Drink before, during, and after activity; use water + electrolyte drinks for long sessions; avoid excess caffeine.

Hydration Needs Depend On

Age, climate, activity level, and diet.

Overarm Throw

Legal javelin throwing method using shoulder and upper arm.

Sector

The marked area (28.96°) where the javelin must land.

Electrolytes

Minerals like sodium and potassium needed for hydration.

Hydration

Having enough water in the body for physical and mental function.

Foul Throw

Any throw that breaks the rules (line, angle, tip-first, technique).
