If you want to design mesocycles of five weeks with developmental nature try the following order:
week 1 STRENGTH
week 2 ENDURANCE
week 3 SPEED
week 4 RETAIN
week 5 UNLOAD
In each microcycle is emphasized more one physical ability with the fourth microcycle be the maintenance and fifth micro the recovery.
The placement of microcycles in this order gives the opportunity not only to players of the starting eleven but and substitutes to improve their physical atributes.
Details on the design and the potential improvements can be found in the following research that i designed and executed with my colleagues:
