As a new event, the speed of each baton may affect the performance of the whole team, so the men's and women's 4 × 100 meter medley relay also tests the ability of the coach to arrange the troops. However, through the investigation of domestic and foreign literature, it is found that there is no authoritative and reasonable explanation of the selection team, which makes the traditional selection method cannot fully express its objectivity and systematicness at this stage. Both subjective and objective factors affect the rationality of the selection. At this stage, how to select the best combination, sub-optimal combination and sub-optimal combination is the key. In this paper, the literature, mathematical statistics, comparative analysis and other multivariate statistical research methods are used to analyze the results of relay events in 2014-2019 international representative events as the research object, and the optimal combination of 4 × 100m medley relay. Through research and analysis, it is found that the traditional selection method for men's and women's 4 × 100m medley relay is based on the ratio selection method. Men should be selected to take part in backstroke and breaststroke, and women should be selected to take part in butterfly and freestyle. This is the best combination method for men's and women's 4 × 100m medley relay. From the perspective of the difference selection method, the difference calculation is carried out for the performance difference between men and women in each event. Men participate in the events with large performance gap between men and women, and women participate in the events with small performance gap between men and women. This is the best combination for men and women to achieve the best performance in the 4 × 100 meter medley relay.
