BIOL1630 SSP Improving Performance: Long Jump
Main summary
Key takeaways
Main ideas & lessons
- Biomechanics can improve long jump performance through training technique and overall results—especially for junior athletes.
- Effective coaching begins with a holistic view of the entire long jump action (run-up → takeoff → flight → landing), then breaks it into phases to identify faults and target improvements.
- Key performance improvements are driven by:
- Maximizing horizontal velocity at takeoff
- Using an appropriate takeoff angle (smaller than the common “45°” projectile idea for long jump)
- Managing body orientation during flight to help the athlete land efficiently without losing rotation control
- Field measurements in competition-like conditions are emphasized as more realistic than lab testing; multiple-camera instrumentation (and potentially force measurements) can capture full performance.
Methodology / actionable instruction set (by phases + measurements)
1) Analyze the whole jump first (holistic → breakdown)
- Take a holistic view of the action:
- Run-off → takeoff → landing
- Then break it into phases and analyze each using biomechanics first principles.
- Identify where the athlete is “at fault” within the phases.
2) Optimize the run-up and takeoff mechanics
- Maximize horizontal velocity at the moment of takeoff:
- Run as fast as possible onto the board.
- Don’t start too far back (fatigue may reduce speed).
- Maintain maximal horizontal distance through the approach.
- Account for the last 2–3 strides:
- Athletes may focus on placing the foot in the correct landing/takeoff position.
- Biomechanical analysis aims to maximize horizontal velocity up until the foot hits the plate.
3) Use the right takeoff angle (not a fixed 45°)
- Don’t assume long jump takeoff should be 45° like a generic projectile model.
- Since the center of mass is higher at takeoff than at landing, use a smaller takeoff angle.
- Typical target: ~35–40°.
4) Control body/limb orientation in the flight phase to improve landing
- Goal: optimize landing mechanics by managing rotation and relative leg position to the center of mass.
- If legs are too far in front of the center of mass when they contact the sand:
- They generate a force that opposes forward travel
- This can cause backward rotation, leading to falling back into the sand
- If the center of mass is above the landing point:
- A forward rotation is produced
- The athlete lands more effectively (described as landing forward)
5) Use realistic measurement methods (field > lab for competition performance)
- Prefer field measurements because they reflect natural, competition-like performance.
- Example instrumentation approach:
- Set up a running track and long jump pit with multiple cameras
- Camera placement:
- One camera to capture motion at takeoff
- A second/third camera to capture flight phase
- A third camera at the landing point
- Consider additional measurement:
- Measure vertical and horizontal ground reaction forces at the takeoff board
- This is easier in a laboratory using a force platform, but harder/costlier in the field
Coaching methodology (what the PE/coach does in practice)
6) Break the long jump into the four phases and diagnose weaknesses
- Use four phases:
- Run-up
- Takeoff
- Flight
- Landing
- Start with a holistic check, then locate weaknesses in specific phases.
7) Match training focus to the athlete’s limiting factor
- If the athlete is weak in speed and not producing optimal speed:
- Increase power and strength
- Use running drills and technical work on sprint mechanics and “speed position”
- Focus on the final steps to transfer horizontal to vertical speed.
Examples by athlete level:
- For young athletes:
- Use simple, mechanically oriented cues/sayings, e.g.:
- “Run hard into karate position in the air”
- “Squat the fly, stomp the toad”
- Goal: help them connect phases visually
- Use simple, mechanically oriented cues/sayings, e.g.:
- For more elite athletes:
- Do a more detailed breakdown:
- Start of the run-up (since they can’t use blocks)
- How they produce force quickly to the board
- Adjust run-up length:
- Stronger/powerful athletes may need a longer run-up
- Less advanced athletes reach optimal speed quicker, so you avoid reducing their speed
- Use drills for sprinting and power, including hurdles to build mechanics and speed.
- Do a more detailed breakdown:
8) Train sprint mechanics using grounding/force concepts
- Use drills emphasizing body position and force production:
- Examples: high knees
- The aim is to create:
- Strong ground reaction forces
- Good reaction to sustain speed, especially near the end of the approach
9) Practice the takeoff and landing with targeted repetition
- Takeoff practice:
- Do drills in/around the takeoff area
- Reproduce the correct takeoff movement pattern repeatedly
- Landing mechanics:
- Ensure center of gravity is forward at landing (avoid rocking back)
- Use drills that combine appropriate takeoff + landing execution
Closing takeaway (course lesson)
- The same biomechanical principles can apply across many athletics events, not only long jump.
- Learners are encouraged to apply these principles in their future workplace.
