Triple Jump: Triple Jump: Techniques, Rules, and Measurement
The triple jump, often described as a “hop, step, and jump,” is one of the most dynamic and thrilling events in track and field. It combines speed, strength, and precise technique to achieve maximum distance. If you’re just starting out with the triple jump or aiming to perfect your technique, mastering its key components and methods is crucial. This guide provides a comprehensive overview of what you need to excel in the triple jump.
Measurement of Triple Jump
Runway
- Length: Typically between 40m and 45m.
- Markings: White lines 50mm in width to guide athletes.
Take-off Board
- Dimensions: 1.22m long, 20cm wide, 10cm thick.
- Material: Made from a rigid material to prevent slipping.
- Plasticine Indicator Board: Positioned beyond the take-off line to help officials determine if a jump is legal.
Landing Pit
- Dimensions: At least 9m long and filled with soft, damp sand for safe landings.
- Depth: Sand should be 50cm deep and level with the take-off board.
Fundamental skill of Triple Jump
1. Approach Run
- Objective: Achieve maximum controlled speed.
- Strategy: Maintain a consistent stride pattern, accelerating smoothly towards the take-off board.
2. Hop
- Execution: Take off from one foot and land on the same foot.
- Key Points: Maintain speed and balance, focusing on distance and height.
3. Step
- Execution: Land on the opposite foot after the hop.
- Key Points: Use the momentum gained from the hop to propel yourself forward, keeping your balance steady and getting ready for the jump phase.
4. Jump
- Execution: Take off from your step foot and aim to land smoothly in the sand pit.
- Key Points: Aim for maximum distance while maintaining form and balance through the flight.
5. Landing
- Technique: Extend legs forward and lean the upper body towards the knees.
- Objective: Reduce backward movement to optimize the measured distance.
Techniques of Triple Jump
1. Flat Technique (Polish Technique)
- Hop: 35%
- Step: 30%
- Jump: 35%
- The hop and step phases follow a flatter parabola, resulting in a lower trajectory.
2. Steep Technique (Russian Technique)
- Hop: 38.5%
- Step: 30%
- Jump: 31.5%
- This technique features a higher parabola in the hop and jump, suitable for fast and sturdy runners.
3. Mixed/Modern Technique
- Hop: 37%
- Step: 33%
- Jump: 33%
- Combines elements of both flat and steep techniques with a take-off angle of 15 to 16 degrees. The height of the center of gravity is intermediate between the two techniques
Rules of Triple Jump
Foul Jumps
A jump is considered a foul if:
- The athlete’s foot crosses the take-off line.
- Any part of the body touches the ground outside the landing area closer to the take-off line.
- The athlete fails to perform the hop, step, and jump phases in the correct sequence.
Measurement
- Distance: Measured from the take-off line to the nearest mark made in the sand by any part of the athlete’s body.
- Method: Measurements must be perpendicular to the take-off line.
Trials
- Number of Attempts: Competitors typically have three attempts, with the top eight athletes receiving an additional three jumps. If fewer than eight athletes are competing, each may have up to six trials.
- Conduct: Athletes must complete their jump within one minute of being called. Leaving the event area without permission can result in disqualification.
Roles of Officials in Triple Jump
- Chief Judge: Oversees the event, ensuring all rules are followed.
- Other Judges:
- Check the take-off, measure the jumps, and indicate the validity of each attempt using white and red flags.
- Record results, manage the scoreboard, and monitor the wind gauge.
- Ensure the landing area is leveled after each jump and replace the plasticine when necessary.
- Keep track of time, ensuring athletes adhere to the one-minute rule for each jump.
Conclusion
The triple jump is a demanding event that requires a blend of speed, technique, and precision. By mastering each phase—approach, hop, step, jump, and landing—and adhering to the rules, athletes can significantly improve their performance. Whether you’re competing at an elite level or just aiming to improve your abilities, grasping the fundamentals is essential for success.
