Swimming technique testing system by prof. Rein Haljand
swimmer Quality of BUTTERFLY TURN technique                            
  1. SWIMMING BEFORE TURN    
 
         
x Timing of moment for touching the wall      
  2. APPROACHING PHASE        
x Forward speed before touch( as high or better compared to swimming)    
  3. ROTATION PHASE        
x Action of arms during rotation (quick recovery,entry when feet touch )  
 
 
x Action of legs during rotation (quick grouping)      
x Placing the feet to the wall (correctly and simultaneously )      
x Speed and movement of hips during rotation (not stoping)      
x Duration of rotation (short)      
x Body position at the end of rotation (side)  
 
 
  4. PUSHING PHASE        
x Timing of the beginning of push (immediately, when feet touch)      
x Body position during push ( fixed during push, no twisting)      
x Mean pushing speed (high)      
x Push duration (very short)      
  5. GLIDING PHASE        
x Head , body and legs position (must be very streamlined )      
x Glide speed after push before leg kicks      
  6. UNDERWATER KICKING PHASE        
x Timing of the beginning the first leg kick      
x Head and arms position during leg kicks  
 
 
x Rhythm and action of legs during kicking      
x Duration and number of kicks to keep high forward speed      
x Speed during leg kicks      
x Trajectory of gradual rise to surface      
  7. PULLOUT PHASE        
x Timing of the beginning of first pullout stroke  
 
 
x Forward speed during first pullout stroke      
x Arms action during pullout stroke      
x Forward speed during first recovery      
x Body position during first recovery      
x The action of body during pullout      
x Timing of arms and legs at the end of pullout strokes      
x Timing the entry of hands at the end of recovery with leg kick      
  8. SWIMMING AFTER TURN        
x Swimming speed after turn (better compared to speed before turn)      
         
         
         
         
         
         
         
         
100%
