Era arrivato alla conclusione che la velocità dipendeva dalla forza muscolare, ma l'aumento di quest'ultima spesso andava in sintonia con una diminuzione del versante resistente.
Inoltre la forza specifica era più influenzata dalla soglia anaerobica e dalla resistenza, che dalla forza massima.
Allora cercava un metodo per allenare la forza in condizioni molto aerobiche o comunque molto specifiche.
Da qui sono nati questi Modified Circuit. Che sono praticamente alla base della "trasformazione" itaGliana.
"Modified Circuits comprise a sequence of exercises for strength and/or technique, connected together with runs carried out at different speeds and over different distances, depending on the final goal of the Circuit.
Concerning this we distinguish for each event three different applications, depending on the period of preparation, that have different goals:
Extensive Strength - Resistance Circuits
In this type of Circuit, which we can consider as a ‘Basic General Circuit’, we have the goal of increasing MUSCLE EXTENSIVE RESISTANCE, carrying out exercises at middle intensity connected one another with runs at Aerobic Threshold pace.
This Circuit is quite Aerobic and builds up the base of Endurance that later we have to develop into Strength-Endurance.
High Intensity Strength - Endurance Circuits
In this type of Circuit, which we use during the last part of the Fundamental Period and during the Special Period, the main goal is the development of Strength. For this goal we use exercises carried out at a very high intensity, taking particular care with technical execution.
In this type of Circuit we must use a high percentage of maximum strength. The speed of the runs connecting the exercises is low and the distance is short so we use running only for regeneration and recovery.
This Circuit is very much Lactic and builds up the base of Strength that later we have to develop into Strength-Endurance.
Specific Strength – Endurance Circuits
In this type of Circuit, the main goal is to develop the ability to recruit the highest possible number of muscle fibres, while the state of fatigue and the lactate levels in the muscles are rising.
In order to reach this goal, THE EXECUTION HAS TO BE CARRIED OUT AT HIGH INTENSITY BOTH REGARDING STRENGTH EXERCISES AND THE SPEED/DISTANCE OF RUNNING.
The interpretation must be very aggressive because, to reach quickly, a ‘lactic state’ very much higher than the AnT is an irremissible condition in order to reach the prefixed goals.
[..]
AS OUR GOAL IS TO USE THE REMAINING STRENGTH IN THE WORST CONDITIONS, as can happen during the final part of a race.
THROUGH THIS TYPE OF TRAINING WE WANT TO BUILD THE CAPABILITY TO RECRUIT A LARGE NUMBER OF FIBRES WHEN THE SATURATION LEVEL IS VERY HIGH.
This training, from our experience, is one of the most important for improving the final sprint in a race. Being a very hard training we can use it only few times during the final part of the Special Period and during the period of main competitions. With this type of training we can assemble Endurance and Strength, previously trained.
Examples of Modified Circuits
During the Fundamental Period
Extensive Strength – Resistance Circuit

Recovery: 5:00 >< 6:00
Repetitions: 4 – 6 times"
