What do you know about tennis racket

What do you know about tennis racket ?

  • According to you, what the ancestor of tennis ?

  • Whatis the date of tennis racket creation ?

  • Whythere are oversizedkind of rackets ?

  • What are the ergonomicsinvolvement in Rackets ?


History of tennis racket

History of tennis racket

  • Appeared with the Jeu de Paume, the first wooden racket was created in 1505

  • Tennis was born at the end of the XIXth century

  • The second sport practiced in France : 1 102 921 members in 8 217 affiliate clubs in 2011


Regulations and standards

Regulations and Standards

  • Size

    • They are defined by the rules of the ITF International Tennis Federation

  • Standardization of the racket

    • NF ISO 11416 defines the components and physical parameters and terminology to be adopted by all manufacturers


Evolution of tennis racket until the 1930s the wood

Evolution of Tennis RacketUntil the 1930s : The Wood

  • Headsize : substantially spherical or square 16.2 cm in width and 16.5 cm in length.

  • The grip is made of wood and cork or bare does not have octagonal shape with flat surfaces and chamfers.

  • The strings is natural gut of sheep or beef.

  • Design is almost absent.


Evolution of tennis racket from the 1930s to 1960s the classicism and laminated wood

Evolution of Tennis RacketFrom the 1930s to 1960s : the classicism and laminatedwood

  • Leather grip

  • Strings are always in naturalgut of sheep.

  • Nylon appearedat the end of the 50’s.


Evolution of tennis racket the seventies the changes

Evolution of Tennis RacketThe seventies : the changes

  • Metal frames easier to produce.

  • Wood frames change to double branchwithstillsmallhead.

  • The grip stretch out for the twohand’s flip side.

  • First frames in fiber

  • The synthetics strings becomewidespread

  • Bighead patent (PRINCE) in 1976


Evolution of tennis racket the 1980 s carbon fibers composites

Evolution of Tennis RacketThe 1980’s : carbonfibers, composites

  • Increasing power of composite racquets

  • Progressive disappearance of wood

  • Research new forms : midsize and largesize head

  • Design more pronounced

  • Commercial life is reduced

  • Metal for the average range


Evolution of tennis racket the 1990 s supremacy of composite

Evolution of Tennis RacketThe 1990’s : Supremacy of composite

  • Generalization of composites

  • Supremacy of midsizehead

  • Relegation of metal

  • Simplifications of forms

  • Development of technicals concepts

  • Aerodynamism, flexibility, rigidity, new headsize design

  • Kid/Adultcompleteassortment


Evolution of tennis racket 2000 explosion of technology

Evolution of Tennis Racket2000 : Explosion of technology

  • Generalization of midsizehead

  • New technology innovation

  • Specialcolor and design

  • Carbon nanotube


Headsize racket

Headsize racket

  • Length : 39,7 cm max

  • Width : 29,21 cm max

  • Surface : 709,67 cm² max


Weight and length

Weight and Length

  • Weight for children and beginners :

    • Varies between 200 g and 270 g

  • Juniors and competitors :

    • Varies between 270 and 360 – 370 g

  • The length:

    • Children : varies from 50 to 67,5 cms

    • Adult : varies from 68,5 to 71 cms


Accessory

Accessory

  • Anti-vibrator :

    • Reduce and absorbshocks to avoid injuries

  • Grip and sur-grip :

    • Absorb the perspiration

    • Better sensation

  • Stip of lead :

    • Modify the weight and the balance for better adaptation of player


Innovation with neither future

Innovation withneither future

  • Over time, more or less fanciful innovations have been created

  • INPI and “google patents” data bases give the latest and other more traditional.


Example of innovation with neither future

Example of innovation withneither future

  • Brian Battistone, is the first playerwhoplayswith racket withtwo grips. He reachedwithhis racket the 853 th in single and the 88 th rank mondial in double ranking.


Future

Future

  • The rules of raquet size are frozen and limitedcreativity

  • Main innovation trail are :

    • Material

    • Manage vibrations control

    • Stringing

    • Accessory (tennis racket cover, bag…)


Future1

Future

  • Play and connect :

    • Captorswhich records

      • Movements

      • Ball’seffect

      • Power striking
