The recruited players followed a training routine of five days per week, with sessions lasting 4 h per day (2 h of swimming training and 2 h of water polo training, except Wednesday-match simulation). Indeed, the athletes trained five days per week, following a mesocycle preparation program. A mesocycle represents a phase of training with a duration of 2–6 weeks or microcycles, where the training program emphasizes the same type of physical adaptations, for example, muscle mass and anaerobic capacity. During the preparatory phase, a mesocycle commonly consists of 4–6 microcycles. The goal of the plan is to fit the mesocycles into the overall plan timeline-wise to make each mesocycle end on one of the phases and then to determine the workload and type of work of each cycle based on where in the overall plan the given mesocycle falls. The goal in mind is to make sure the body peaks for the high priority competitions by improving each cycle along the way.
