Swimming technique testing system              by prof. Rein Haljand
swimmer Quality control of  BACKSTROKE SWIMMING  technique            
  1.Left ARM PULL & Right RECOVERY  PHASE     
 
 
x ·The position of left shoulder (must  be relatively high)    
x · The timing of left catch,right exit,left kick (must be simultaneous )    
x · The  left arm pull action ( good catch down, aside, fixed elbow position)    
x · The position of left arm at the middle of stroke (vertical, max flexed)    
x · Left hand slip during pull (positive, let your body move on the pull)    
x · Forward speed  (compare to speed during right pushing phase).    
  2.  Left ARM PUSH & Right RECOVERY PHASE        
x · The left arm push action (elbow and hand close to body, with wrist locked e.c.t.)    
x · The timing of recovering  arm entry (must be before the end of the push)
 
 
x · The timing of left arm pushing with left leg  kick (must be simultaneous)    
x · Left hand slip during push (less negative, sticking to water)    
x · Forward speed (higher, compare to speed during left pulling phase)    
  3.Right ARM PULL & Left RECOVERY  PHASE         
x ·The position of right shoulder (must  be relatively high)
 
 
x · The timing of right catch,left exit,right kick (must be simultaneous )    
x · The right arm pull action ( good catch down, aside, fixed elbow position)    
x · The position of right arm at the middle of stroke (vertical, max flexed)    
x · Right hand slip during pull (positive, let your body move on the pull)
 
 
x · Forward speed  (compare to speed during left pushing phase).    
  4.  Right ARM PUSH & Left RECOVERY PHASE        
x · The right arm push action (elbow and hand close to body, with wrist locked e.c.t.)    
x · The timing of recovering  arm entry (must be before the end of the push)  
 
x · The timing of right arm pushing with right leg  kick (must be simultaneous)    
x · Right hand slip during push (less negative, sticking to water)    
x · Forward speed (higher, compare to speed during right pulling phase)    
  5. FULL STROKE CYCLE        
x · Body and wave position, sholders roll (individual optimum)
 
 
x · Left hand relative speed backwards (the slower the better sticking to water)    
x · Right hand relative speed backwards (the slower the better sticking to water)    
x · Movement during left stroke & right recovery = half stroke length    
x · Movement during right stroke & left recovery = half stroke length    
x · Stroke length (the longer the better)  
 
x · Frequency  (keep individual optimum)
