Periodization of the training volume and intensity of aerobic and speed training

	Week 1	Week 2	Week 3	Week 4	Week 5	Week 6
Speed training*	3 × [15 + 15] m with 25 s rest between sprints	4 × [15 + 15] m with 25 s rest between sprints	5 × [15 + 15]-m with 25 s rest between sprints	3 × [15 + 15]-m with 25 s rest between sprints	5 × [15 + 15]-m with 25 s rest between sprints	6 × [15 + 15]-m with 25 s rest between sprints
Aerobic training**	3 × (10–10 s) at 110% of final velocity (TD: 60 s)	4 × (10–10 s) at 110% of final velocity (TD: 80 s)	5 × (10–10 s) at 120% of final velocity (TD: 100 s)	3 × (10–10 s) at 120% of final velocity (TD: 60 s)	5 × (10–10 s) at 120% of final velocity (TD: 100 s)	6 × (10–10 s) at 120% of final velocity (TD: 120 s)

The rest was active and the intensity was maximal during the two training programs, *sprinting at maximal intensity, **the rest between sets was 10 s, TD: total duration of each aerobic session, both training programs included a linear progression based on the number of sets using respectively the number of sprints for the speed training and the final velocity percent for the aerobic (HIIT) training program (undulatory periodization model)
