The SL is influenced by the hydrodynamic action of the flutter kick itself, by the distance reached by foot, and the power of the catch. The SR is the number of strokes per second. The SL can be varied by the distance reached by foot or by the power of the catch. The SR is determined by the muscular power of the competitive swimmer and by the technique used . The SR is also important since it influences the economy of propulsion generation, by which swimming performance is defined . The SR is affected by the technique used. For example, for dolphin kicking, the SR should be as high as possible. Likewise, for breaststroke kicking, the SR should be as low as possible. The SR and the SL are thus important in optimizing swimming performance. The SR can be increased in any technique as long as the SR is of sufficient quality and quantity. In breaststroke kicking, the SR can be decreased in order to increase the SL. In fin swimming, the SR can be decreased when the swimmer uses an optimal technique based on SR and SL. But this should be very conscious and should be adapted to each fin design. The SR increases with increasing SR, and the SL is also increased with increasing SR . So, although the SR may be increased, the SR and the SL should not be too high at the same time. Using a short SL and a high SR together increases the hydrodynamic resistance, thereby reducing the speed . In fin swimming, it is impossible to increase both the SL and the SR. The increase of one parameter is accompanied by a decrease of the other . In breaststroke kicking, the SL is increased by simultaneously decreasing the SR. In this case, it is recommended to use a high SR accompanied by a short SL. In fin swimming, the SR must be increased and the SL must be decreased. It is, therefore, impossible to increase both parameters at the same time . Therefore, it can be stated that the SL of fin swimming should not be too short or too long. In fin swimming, the SL should be as long as possible while the SR should be as high as possible. This is achieved through the regulation of the SR and the SL. This strategy is all-important for the swimmer as well as for the coach. It can also be stated that the SR can be increased, however, the SL should not be too short.
These results may appear contradictory, because in the fin swimming techniques without diving gear the SR was higher than in breaststroke kicking. However, in fact, the SR was higher in fin swimming techniques without diving gear compared with dolphin and flutter kicking, while the SR in breaststroke kicking was lower than in fin swimming techniques without diving gear. A low SR in dolphin or flutter kicking led to a long SL. A high SR in breaststroke kicking led to a short SL. A low SR in fin swimming techniques without diving gear led to a long SL. A high SR in breaststroke kicking led to a short SL. 827ec27edc
