parameters
Duration of reaction with preflexion (sec)rein haljand: (This parameter indicate not only reaction to signal, but also time spent to all preparation movements before beginning real pushing actions. It is easier to reduce that duration, then pushing time)  0.60 0.5L. Frolander  0.60 0.54J. Deglau
Duration of pushing action (sec)rein haljand: (It indicates pushing power, as well explosive form of push)  0.20 0.12D. Carlsson  0.20 0.12J. Malar
Forward speed of head during push (m/sec)rein haljand: (Head speed forward indicate how pushing by legs, body and head move fast forward to take fly-off position) 4.2 6.03S. Pietucha 4 4.73J. Sjoberg
Forward speed of body during flight (m/sec)rein haljand: (This is main parameter of successful flight, high flight speed is precondition for good start) 4.25 5.31G. Pulle 4 4.27K. Larka
The length of head entry (m)rein haljand: (Head must enter after arms to the same length as far as possible) 2.8 3.27R. Coxo 2.5 3.02J. Deglau
Forward speed of hands during entry (m/sec)rein haljand: (High entry speed shows swimmer quality of streamlining and will guarantee continuous high speed for following gliding) 4.8 5.32G. Pulle 4.5 4.9A. Shwarz
Forward speed of body after entry (m/sec)rein haljand: (This parameter shows also swimmer hydrodynamic streamline qualities and timing of the first leg kick actions) 3 4.09G. Pulle 3 3.58M. Limpert
Forward speed during legs kick (m/sec)rein haljand: (Efficiency of underwater undulation movements and leg kicks) 2 2.2M. Mintenko 1.7 1.99J. Amey
Duration of legs kick (sec)rein haljand: (If speed is high, then duration may be longer ,if low then shorter) 2.5 4.76M. Mintenko 2 3.9M. Santos
Forward speed during pullout armstroke (m/sec)rein haljand: (Parameter indicate efficiency of that strokel) 1.9 2.27D. Carlsson 1.7 1.97J. Sjoberg
Forward speed during first arms recovery (m/sec)rein haljand: (Parameter indicate effect of the first recovery movements, rationality of speed fluctuation) 1.7 2.07S. Pietucha 1.5 1.76J. Deglau
Forward speed of swimming cycle after start (m/sec)rein haljand: (High speed indicate good swimming technique after start movements and must be compared with pullout cycle speed before it) 1.7 1.93D. Carlsson 1.6 1.65A. Shwarz
Butterfly start time 15m (sec) 6.46 5.84 7.50 6.90
