The classification is specified to age group, gender, and swimming strokes. Through literature study and expert interview, the relationship between different swimming strokes and the medley relay achievements has been verified. The inner discipline has been quantified with equation. The"relatively weak swimming stroke"has been found and waits for focus retraining. The ultimate goal is to achieve all-round development with the improvement of the medley relay achievements, which is known as attain two objectives or gain two advantages by a single move.
