Microcycle is the training work unit that can be various on lasting, structure and contents. In praxa microcycles last 2-14 days, but the most often variant is 7 days.ecause of that it can be told that there is no unique, universal microcycle structure that can be thought to be equally good for each possible cases. In the theory of sports training there is multiple microcycles classifications.
3 week-shock microcycle, very high load, three workouts with very high load. 4 week-recovery microcycle, small load. 3) Shock mesocycle â training load would be taken to the highes possible level to induce a high stress in the body to evoke maximal supercompensation after following revocery.Such kind of mesocycles can be done only 2-3 during the preparatory period. week-regeneration microcycle, average load, one training with high load. 4 week-recovery microcycle, small load. 5) Competition mesocycle â nhe number of those mesocycles is characterized by the nature of the sport discipline, the level of the athlete and the competition calendar.
