Skateboarding

Description

These are some notes from speaking with USA Skateboard Education Association.

Joe Eberling and Chris Hargrave

The Ollie

• discover how to teach an ollie faster and safer
• minimize injury
• analyze people that can't ollie to find what is missing
• I should watch coaching tutorials (most focus on one thing instead of all things).
• Ollie is good fundamental trick to study.

Speed generation in pumping

• How to pump a transition

• Tick tacking

• How to pump a bowl

• Example of extraordinary pump (Sandro Dias) bailed: one pump to get a 540.

• Progressive transition so that it goes from less steep to steep.

• How pressure distributes across the board due to foot position.

• Most common thing to cause injury: twig stopping wheel

• How many different foot positions for different tricks

Drop in

• How do we get people into doing that.
• Environment is wrong for learning.
• Aesthetics effect the emotions and fear.
• Design drop in ramp: progressive

Shape and intensity of features

• Optimal tranny shapes
• How many skatepark designers understand how to design the shape.

Grindline: builds skateparks

Rating system for skateparks

Framework for simple ranges of motion that are common throughout skateboarding. What are the extreme ranges in motion and what is the neutral "range". Chris focuses on four ranges: up/down, rotation, foot to foot, toe to heel.

Current: Joe is trying to learn backside 50-50s. Moving different steps: head, shoulders, carving into backside by weighting.

Board that shows pressure

Lateral learning: look to opposite wall.

Chris does a weekly call for snowboard instructors.

Created this MSc proposal from this: https://github.com/mechmotum/ideas/blob/master/msc/skateboarding-learning-safety.rst

There is an Urban Sports Performance Center in the Netherlands: http://uspc.nl/

Ideas I sent to Sport Experience:

• Development of an instrumented skateboard (force and kinematic measurements)
• How does the ollie work? Applying this knowledge to ease learning the trick and optimizing for height.
• Design of safer ramps for aerials in skateboarding- Design of ramps and boards to maximize safety while learning ramp tricks- Data analysis of instrumented skateboards for real time coaching of skateboard tricks
• Labeling and categorizing skateboard tricks from a single IMU on a skateboard
• Finding the limits of human performance in skateboard tricks (e.g. what are the physical limits we can reach on person or board rotations)
• Optimizing skateboard materials for pop, longevity, sliding, and strength
• Optimal trick choice strategy to maximize points in a free skate competition
• Development of training methods to learn different skateboard trick
• Determine the main injury risks in skateboarding and training for prevention
• Effectiveness of safety equipment- Reduce falling in electric skateboards with smart controllers
• Characterizing professional skateboard tricks to provide benchmarks for performance
