Lecture 17 Technology supporting the Paralympic athlete Flashcards
What are the wheelchair sports?
- Wheelchair tennis
- Wheelchair rugby
- Wheelchair basketball
- Wheelchair racing
Explain the paralympic technological scientific support.
Marginal Gains
No stone is left unturned in pursuit of excellence and the approach is to use an evidence base scientific approach, with best practice and know-how shared across other mainstream sports (if relevant) and Paralympic programmes
* Growing in popularity and the sport has grown and grown in terms of participation and media coverage and support
* More and ore support for the paralympic athlete.
* Margins are getting smaller and people are taking it more professionally.
What are the wheelchair configurations for adapted sports?
- Seat width
- Wheel size tyres
- Frame
Camber angle
Foot plate - Wheel base
- seat backseat
- Seat depth
-Castor wheels - Spokds
- Wheel axis
- Seat angleSignificant developments over time
- Wheelchair configuration and design
- Technology used.
- Everything is getting better
- Examination
- Trial and error, subjective perception
- Individual comes in and has a question and discusses what they want to change in the chair
- However there is still limited research in what can be changes in the chair.
- Working towards evidence-based research

- Examination
- Trial and error, subjective perception
- Individual comes in and has a question and discusses what they want to change in the chair
- However there is still limited research in what can be changes in the chair.
- Working towards evidence-based research
What do GPS systesm do on the wheelchairs?
- Uses satellites to obtain time & location data
- Being heavily used in professional team sports nowadays – E.g. Soccer & Rugby
- Provides info about the distances covered, speeds reached, and times spent in certain speed zones etc.
- Used in able bodied sports.
- Used to get information such as speed and distance covered.
Explain the indoor tracking system
- They have tried to apply a similar stem I wheelchair rugby
- They built an indoor tracking system sand put the sensor on the chair of the athlete.
Explain the classification system for wheelchair rugby
- Can get lots of detailed information
- An see that wheelchair rugby squad from 2014
- Can see all the diff players with different points
- Wheelchair rugby uses a point system
- The players on court play with 4 players on court
- There is a combination of different injury types
- There are people with amputees and spinal cord injuries.
- Wheelchair rugby is made from different athletes with differ points (different impairments
- Can see how impairment affects things such as total distance covered.
- But also, the peak speed reached as they have lots less force to apply to the hand frames.
Explain instrument measure wheels and what they were developed for?
Developed for rehab: for people to use in the rehab centre to measure the orecs in the X Y Z location
* Advantages
- Power measurements
- Push by push analysis
* Disadvantages
- Bulk and heavy big hub in middle of wheels.
- Not easily attaches.
Explain the effect of wheel size ]:
- 2 lines on top of one another
- Solid line is bigger wheels
- Dotted line is smaller wheels
- Solid line stops earlier as they reached the end of the sprint earlier.
- Top speed higher in the bigger wheels.
- Can also see the bigger wheels at the start it too them longer to get up to speed.
- When we are in motion its much easier to move the wheels.
What are inertial measurement units?
- These are the device spoke about at the start
- Small devices
- They have a gyroscope and accelerometer inside them
- With these devices, one in the hub of the wheel and one I the frame of the chair
- We know how fast the wheel is spinning and how fast that the chair spinning.
- We know how fast the athlete is making turns and moving around the court.
- Can know how the athletes is turning on court.
What are the advantages and disadvantages of inertial measurements units (IMU’s)
- Advantages
- Small
- Lightweight
- Easily attaches
- No disruption athletes: wont notice that they are on the chair.
- Disadvantages
- No power measurement.
What are the difference between sports in disabled athletes?
- wheelchair tennis there is lots of rotational forces
- Wheelchair tennis players have higher rotational velocity than wheelchair rugby and basketball players.
- Can apply to all the court sports.
- Can see the wheelchair rugby circle is in the middle and this is because it’s usually played by athletes with less physical function
- In wheelchair tennis there are more rotational figures involved.
How do we process the data from a sprint analysis?
- Linear aspects
- Gyroscope wheel
- Camber correction
- Rotational aspects
- Gyroscope frame
What is a sprint analysis ?
- Acceleration signal
- Push detection algorithm
- Number of push cycles
- Cycle time
- Displacement push.
Developed algorithm based on acceleration potential
Can put more detail into and get more out of what is happening on the court.
Explain the differences between talent and professional athletes?
- Rotational V of talented athlete is much higher compared to development player.
- Top figure is spider test: where we are making small figure of eights
- Can see smoothness of the data of the professional athlete, the development athletes does not have as smooth turned.
- Can track athlete throughout their career and see development over time.
