parameters
Forward speed of swimming cycle before turn (m/sec)rein haljand: (Speed before turn is good to compare to speed after turn)(Higher speed before turn is precondition for better turning actions) -1.6 -1.88L. Frolander -1.4 -1.69J. Sjoberg
Forward speed before touch (m/sec)rein haljand: (speed before touch indicate how good was timing to touch the wall, compared to swimming speed before turn) -1.6 -1.84S. Pietucha -1.4 -1.61J. Sjoberg
Duration of rotation (m/sec)rein haljand: (Indicate effect of grouping and turning) 0.85 0.62D. Carlsson 0.94 0.74J. Amey
Forward speed of hips to wall during rotation (m/sec)rein haljand: (Shows that hips stops during beginning of rotation or continues moving fast forward together with grouping of legs) -0.5 -0.75J. Hickman -0.3 -0.56J. Deglau
Push-off duration (sec)rein haljand: (Push off duration indicate power of pushing : then shorter then better, but if swimmer is waiting before pushing, this duration considered as extra unnecessary time) 0.3 0.16S. Pietucha 0.3 0.2S. Nordenstam
Forward speed during push (m/sec)rein haljand: (Average forward speed of hips during pushing indicate effect of pushing action) 1.4 2.22J. Hickman 1.3 1.9S. Nordenstam
Forward speed of gliding after push (m/sec)rein haljand: (This parameter shows swimmer hydrodynamic streamline qualities and right timing of the beginning leg kick actions) 2.25 2.62M. Mintenko 2 2.33J. Amey
Forward speed during legs kick (m/sec)rein haljand: (Efficiency of underwater undulation movements and leg kicks) 1.65 1.88M. Mintenko 1.5 1.67J. Sjoberg
Duration of legs kick (sec)rein haljand: (If speed is high, then duration may be longer ,if low then shorter) 2.5 4.92 1.5 2.9J. Button
Forward speed during pullout armstroke (m/sec)rein haljand: (Parameter indicate efficiency of that strokel) 1.8 2.2D. Carlsson 1.6 1.84J. Sjoberg
Forward speed during first arms recovery (m/sec)rein haljand: (Parameter indicate effect of the first recovery movements, rationality of speed fluctuation) 1.6 2G. Pulle 1.4 1.56J. Sjoberg
Forward speed of swimming cycle after turn (m/sec)rein haljand: (This parameter need to be compared to swimming speed before turn and it must be same or higher) 1.6 1.72S. Pietucha 1.4 1.6J. Sjoberg
