EAPI

• Skill strength- breaststroke leg action


  -drive leg so fast during glide phase and they get a good distance per stroke

  -simple skill which is gross (involves large muscle groups)

  -self paced

  -discrete (clear beginning and end)

  -Swimming tends to be closed skill based (environment doesn't change)

  Allows to get in good body position so more streamline
• Skill strength- turns


  -shown in the video when the performer comes off the wall fast to overtake competitors

  -plants feet on wall knees and ankles, which are examples of hinge joints at 90 degrees

  -allows them to maximise powerful push off

  -example of a isotonic concentric muscle contraction
• Fitness strength-muscular endurance

  -strong back end

  -increased speed last 50m

  - cardio endurance very important as it means they can swim at moderately fast pace for a long time

  -best was to train this is continuous training of fartlek as it is long efforts with short rest
• Fitness strength- power


  -seen on their push off the walls
• Skill weakness-dive

  -the swimmer was last to 15m

  -the take your marks position is an example of an isometric contraction

  -having a good dive is beneficial as it means you carry speed better through the water and and also if you start ahead it can give you confidence
• Skill weakness- backstroke BP


  -because their hips sank in the water which made them less streamlined
