THE FLYWHEEL TRAINING
The training with centrifugal force in the form of kinetic energy is an innovative development in the field of sport and physiotherapy. Instead of conventional weights, you train with flywheels that work independently of gravity. Every movement takes place in two phases: concentric phase and eccentric phase.
The two specific phases are analyzed in the graphics below, wherein we represent example values of the concentric and eccentric energy (who change their direction during a cycle) as numbers in mathematic module, with positive values for both phases.
Phase 1 - concentric movement:
By investing muscle energy to pull on the grip and accelerate the flywheels, they will store kinetic energy.
As soon as the tape is completely unwound, the traction tape will be at its maximum length, it will result a “point of return”, where the traction tape will change its direction of movement and starts to wind up, like an inverted Yo-Yo.
Depending on body tension and training style, the amplitude and speed of the "point of return" can be used as a longer or a shorter "relaxation" of the muscles.
Phase 2 - eccentric movement:
When the tape begins to wound up, it will braked by muscle force. The eccentric phase starts instinctively.
The person who trains cannot remain passive. It will be pulled by the stored kinetic energy with almost the same energy he invested itself to rotate the flywheels and must brake them. That reaction occurs instinctively.
This phase lasts until the traction belt reaches its shortest length and the flywheels are braked at zero speed.
Through acting a new concentric traction, a new cycle will be launched.

The generated energy can be directed to the desired part of the body through the simple body tension and position. Individual muscles or muscle groups can be targeted trained with the same method. As soon as you get used, understand and are able to control the movement, you can stepless adjust the intensity of the training energy.
CLINICAL STUDIES on training with centrifugal forces
Numerous studies confirm the effectiveness of flywheel eccentric training, which is the reason why this method is used by top athletes and for therapy and rehabilitation purposes.
The special element of the flywheel training is the eccentric contraction - a phase that does not exist in training with gravity, which is only limited to concentric contraction.
The interaction between the concentric and eccentric phase also enables faster rehabilitation and prevents injuries.
During the eccentric contraction, greater muscle strength can be achieved.
Eccentric contractions also tire more slowly, which is more efficient from a metabolic perspective compared to concentric contractions. Eccentric training is more effective in increasing muscle strength and more effective in building muscle mass.
The jumping power and core strength are also increased.

"You are the designer of the only exercise device that will easily work in a spacecraft. NASA plus the private space companies SpaceX and Blue Origin will be using your product, which means incredible publicity for marketing to all people.
Everyone wants to exercise like an astronaut."
