The contemporary model of preparing competitive swimmers in a given year is based on the following sequence of training and competition: preseason, early season, competitive season, taper, championship season, and recovery or off-season. For highly trained swimmers the competitive season usually takes the form of domestic competition or international competitions.
The championship season typically involves the national championships, often doubling as the national team selection trials, and then the major international competition for that particular year.
Once the competition schedule has been established, the training plan can be prepared with the goal of maximizing the performance of the swimmer for the competitive and championship seasons. For international swimmers, the entire season is typically 44-48 weeks in length with a short break permitted after completion of the championship season. The length of each of the different training phases will vary according to the individual circumstances of the swimmer, team, and coach. In recent years, the international swimming calendar has become more crowded and as a consequence the annual training plan has become more fragmented and complex.
