Transcript of technology in sports

Soccer Goal-line Technology
Case Study: London Olympics 2012
Positive Impacts of Sports Technology
Possible/ probable problems that might arise in the future
Facilities to accommodate the progress of sports competitions such as by:
A method used to determine when the ball has completely crossed the goal line with the assistance of electronic devices
Technology In Sports

Assisting referees or umpires to make the right calls.
Preventing games from being marred by human errors
Equipments used by athletes (disabled or not) to improve their performance level
Clothing and Equipment Design
Safer sports participation
Provide comfort
Tailor to needs of different
Sports Enhances performance
Improvements made with technology applied
Safer sports participation
The increased safety and reassurance in sports is thegreatest benefit for sports lovers.
E.g: Invention of bike helmets, which would help to protect the skull in accidents.
Increased comfort
For the majority of people who participate in sports for leisure purpose (non-competitive level), comfort is one of the top choices when choosing our equipment.
Eg: Nike Air
"Air cushioning technology"
Embeds small pouches of air within the midsoles of its running shoes
With each step, each unit compresses and recovers for the next step
Design in tailoring to needs of sports
Enhancing performance
Application of composite materials have helped to reduce weight while yielding increased strength
Found in highly competitive sports, such as bikes, skis and rackets

Eg. In swimsuits
Swimsuits made of urethane are water repellent, improves buoyancy, reduce drag, and maintains swimmer's optimal body position in the water
What is urethane?
Foam-like substance
Rigid foams: Inside the plastic walls of most refrigerators and freezers
Flexible foams: behind the upholstery fabrics in furniture
Assists the referee in calling a goal
Ensure smooth flow of event, impartial decisions and avoids controversies
"Now we can get down to the track, and down to the poolside, and measure an athlete's ability, and give instant feedback to a coach. That way the athlete can go back straight away, and do it again - only better,"
Athlete Performance
Help coachs to better understand individuals.
Easy to spot weak spots
Provide better and more effective help
Eg. Nike Hyperdunk+
Measures height of jumping, speed etc.
Laser pistols ( For Air weapon)
The new laser-based guns allow for electronic scoring
Officials will no longer have to look at physical marks on the target
Provides judges with a much easier job.
2. Ethical problems
Due to the exploitations of performance-altering technology (especially in competitions), hence going against one's moral values.
Four Fingers And 6.6 Pounds
Ever wonder how did swimming results appears
almost instantly?
Swimmer’s best times is registered by the contact pads on the side of the pool once
6.6 pounds of focused pressure
is applied to the pad.
Technology made sports more convenient,accessible, and popular.
Enable higher accessibility:
This technology is so
that the pads could register a time difference of one one-hundredth
(0.01) of a second.
3. What to count as a valuable kind of performance in sports?
As athletes use sports technology to boost their performance,
"running faster may not mean running better".

Very little can be said about their credibility in terms of skills level.
Smile, You’re On DiveCam!
How About the images for diving competitions?
It’s actually an invention called the DiveCam! Working with two primary school physics laws:
The pulley system and The Gravity.
The speed of which the camera descends is determined by the laws of physics and so for the entire length of the drop the camera is in line to the diver.
Diver leaves the spring board
Camera drops down
Stopped by a break system after the impact of the water is felt
Rise back up to the top.
Important information readily available to the coaches, athletes, and spectators.
E.g. The innovation of American football plastic helmet
Used as a weapon against the player's opponents, as its robust structure allows a significant impact upon another person's body.
Increase availability of better and more accurate information
Enable higher accessibility
Aiding Referees
Being able to redesign safer competition boundaries
Being able to redesign safer competition boundaries:
For e.g, climbing gyms facilities enable the public to enjoy sports that they would normally be unable to do unless they were in the wilderness.
Increase availability of better and more accurate information:
The Hawk-Eye system is a typical example of a
beneficial technology that provides a multitude of information during cricket and tennis matches.
Aiding Referees:
The high cost of technology
Ethical problems
Many landing slopes in winter-sport freestyle parks are still constructed according to an old design that is dangerous.
Problem in defining what to count as a valuable kind of performance in sports
Uneven distributions of applications Results to:
athletes/teams that receive much more advanced clothing/equipment will outweigh the others in terms of performance level
1.The high cost of technology
Due to expenses involved, these technology applications tend to be limited to the upper end of sports hierarchy as they are more likely to be able to afford them.
Using feed from cameras taken from different angles can help referees to get an all-round view of the actions.
E.g. To settle controversial disputes on the spot.
With technology, engineers develop safer landing slopes, limiting the number of ski-related injuries.
The technology was not used in sports until 2001 although it had been found in 1999, when Matrix hit the screens.
