traditionele krachttraining en zorgt ervoor dat
je in de concentrische fase ook sterker wordt.
De 'excentrische overload' is m.n. een goede
prikkel voor het bindweefsel van de spier en
pees (myofascia). Die wordt sterker en daarmee
vergroot je de belastbaarheid. Vliegwieltraining
is een bewezen effectieve excentrische
krachttraining voor het hele lichaam en een
zeer geschikte behandelmethode binnen de
fysiotherapie en revalidatie. Veelvoorkomende
blessures zoals hamstringblessures,
achillespeesblessure, patellatendinopathie,
schouderinstabiliteit, rotatorcuff tendinopathie
kunnen met vliegwieltraining goed behandeld
worden. Ook voor valpreventie, postoperatief,
het tegen gaan van sacropenie of mensen met
een CVA is de vliegwieltraining heel geschikt.
Diverse studies hebben aangetoond dat
vliegwieltraining significant meer effect heeft
op spierkracht, spieromvang, sprongkracht,
loopsnelheid, en het versterken van bindweefsel
en pezen.
How does it work?
ENG •
Flywheel training is a unique
development in sports and physiotherapy.
Training with a flywheel is often referred to as
kinetic training. Instead of traditional weights,
a rotating disc is used during training. In the
concentric phase, the flywheel is set in motion
and accelerated by pulling a webbing. When
the webbing is completely unwound, so much
kinetic energy has been built up that the
webbing rewinds itself, just like with the well-
known yo-yo. The goal is to brake the flywheel
and then start it again in a concentric motion.
The resistance you experience is therefore not
due to gravity, but due to inertia, also known as
(mass) inertia or (rotating)
kinetic energy. The harder you pull, the faster
the flywheel will turn, and the more inertia will
be created. So, you will need a lot of power to
stop the flywheel afterwards!
Eccentric training and overload
Eccentric training improves strength, speed,
power and performance-related skills such as
jump height and running speed to a greater
extent than concentric or traditional training.
What do we mean with eccentric training
and eccentric overload? Lifting a weight with
your biceps is a great example of a concentric
movement. Your muscles shorten and therefore
lift the weight toward the ceiling. When you
extend your muscles again, the weight returns
to the starting position. Lengthening the
muscles and thus lowering the weight is called
an eccentric movement. It is possible to make
an eccentric movement without much force. For
example, by lowering a lightweight dumbbell.
However, when we talk about eccentric
overload, we are not talking about a lightweight
movement. A movement contains eccentric
overload when you produce more force in the
eccentric movement than you can produce
concentrically. In practice, this often means
that you lower more weight than you can lift
(> 1RM). Therefore, slowly lowering a weight
does not have an eccentric overload if you
could also lift the weight. It should come as no
surprise that slow eccentric movements do not
yield the same positive results as true eccentric
overloads such as flywheel training.
Exercises in flywheel training are also more
multi-functional because at the beginning of
the eccentric phase you have to slow down
considerably and remain in balance and
therefore you train more muscles (especially
your abdominal muscles) and improve your
balance.
For all target groups
Training with Kynett is suitable for many target
groups such as top sports, rehabilitation,
physiotherapy, personal training, fitness and
sport-specific training. You can train lightly or
intensively, and for speed and strength.
