Research on the Special Fitness for 100m Swimming Based on AHP Model
Abstract
Taking the special fitness for 100m swimming as the object of study, this paper, through theoretical analyses and practical demonstrations, constructs the hierarchy factor table of the special fitness for 100m swimming, establishes the hierarchical model of the special fitness for 100m swimming, and discusses the correlation between the special fitness for 100m swimming and the 100m swimming ability, so as to provide references for 100m swimming training. This paper constructs an index system of the special fitness for 100m swimming by means of Delphi Method in the first place, then establishes the relative weight of special fitness indexes of 100m swimming by AHP, and finally analyzes the correlation between the special fitness for 100m swimming and the swimming ability through logical analysis. The special fitness structural model consists of 5 first-level indexes, 6 second-level indexes and 10 third-level indexes. Among them, the first-level indexes and their weights are as follows: speed quality (0.32); endurance quality (0.27); strength quality (0.22); flexibility quality (0.1), coordination and agility quality (0.09). The second-level indexes and their weights are as follows: displacement velocity (0.24); muscular endurance (0.23); aerobic endurance (0.21), rapid strength (0.16); specialized flexibility (0.09), specialized coordination and agility (0.07). The third-level indexes and their weights are as follows: 50m swimming (0.19); 200m swimming (0.18); 4x50m hand-stroke swimming (0.14); 4x50m leg-kick swimming (0.14); 15m swimming (0.1); shoulder extension (0.06); standing long jump (0.05); 1min superman exercise (0.05); sit and reach (0.05); 1min rope skipping (0.05). The special fitness structural model of 100m swimming constructed in this research has certain scientific and practical significance in guiding swimmers to swim. It suggests that swimmers get more training in 50m swimming, 200m swimming, 4x50m hand-stroke swimming, 4x50m leg-kick swimming and 15m swimming.
