It is well known that powerful movements of the legs counteracted by the least hydrodynamic resistance during the preparatory phases play a decisive role in the creation of the propulsive force of a breaststroke swimmer. In practice coaches advise swimmers to master various leg movement patterns which differ in the degree of flexion in both hip and knee joints. Most of the recommendations in this respect are based on the analysis of motion pictures of top level swimmers and results of electronic recordings of the selected parameters. These analyses only reflect amplitudes of the movements within the breaststroke cycle. But the main question as to how the power potential of muscles utilized in the leg kick can be used most efficiently remains unanswered.
