Analysis of Relationships between the Level of Errors in Leg and Monofin Movement and Stroke Parameters in Monofin Swimming

Table 4. The values of Pearson’s correlation coefficient between the value of errors committed by all swimmers researched, in the sphere of each angular parameter analyzed, and the stroke parameters on all nine of the 100m-intervals of the test distance.

*Statistically significant correlation coefficients (p=0,05).Note: (αER) – error of the angle of flexion in foot at ankle joint; (αER) – error of the angle of bend in tail of monofin; (βER) – error of the angle of attack of distal part of fin; (βER) – error of the angle of attack of entire surface of fin; (SF) mean stroke frequency; (SL) mean stroke length; (AMP AMP, AMPAMP) amplitude of displacement of the segments analyzed.
