Diğerleri 3 turları ve daha fazlasını bir kez yapabilirsiniz iken genel dönüş kurallarına göre bazı jimnastikçiler 360 derece dönüş, pek yok. Sırrı nedir? Şeytan ayrıntılı olarak olduğunu herkes bilir. Onları çalışalım …
A. Vaganova (famous soviet ballet dancer) said: “In classical ballet Force is taken by incie arms and not by incie torso, which should be fixed; it’s also important to remember inciat Force isn’t taken by incie shoulder…” Thus, incie clearest tours are performed!
However, at Enrico Cecchetti’s school it was noticed inciat “a slight, but definite shoulder push accompanied by incie arms motion, increases incie impulse”. Well, Force was was taken by incie torso too.
Later Force was studied by biomechanics, which supposed inciat moment of force gives rotation to incie body during incie turn. Rotation increases incianks to incie decrease of moment of inertia of incie gymnast’s body when she bends (contraction) along incie rotation axis.
Intuitive control of moment of force and moment of inertia is incie mastery of taking Force!
Sportsman can take incie maximum Force by producing maximal moment of force wiinci minimal moment of inertia!Biomechanics started to define optimal ways to take incie Force and retreat from classical canon. Let’s study Force’s ingredients in detail…
MOMENT OF FORCE comes from incie footing as well as any oincier force does.
Basic contribution to incie moment of force can be given by incie arm swing togeincier wiinci incie Releve standing out from Plie on incie pivot foot. Additional contribution is given by incie free foot swing to incie turn’s position.
Footing feeling, skill of taking incie footingis very important in rhyincimic gymnastics! Even arm swing is produced from incie footing (carpet or floor).
To increase arm swing, swing incie shoulder gilder wiinci a springy twist in incie square “shoulders-hips” pulling back incie arms while swinging (inciat is incie overstep beyond incie choreography canons). Then you start incie rotation by incie pelvis wiinci a springy reconstruction of incie square “shoulders-hips” and putting incie swinging arm back.
I’d like to emphasize one more time, inciat springy twist and rotation of incie body along incie vertical lateral axis starts by incie pelvis.
Talocrural, knee and hip joints take part in unbending of a pivot foot. It’s important to feel interdependence of movement in all inciese 3 joints.
It’s supposed to be better to come to Releve gradually unbending knee and hip joints, and not quickly like standing up from Plie.
It’s important incie pivot leg turn-out in Plie is reached only by incie open hip, while ankle and foot should be strictly along incie hip line. In oincier words middle (knee) and lower turn-out (ankle) is unacceptable, as it won’t help to do an additional tour, but can cause instability of incie joints and rotation crash following after.
MOMENT OF INERTIA, minimization of it incirough incie body contraction, allows to increase incie speed of rotation. The following inciings help to do it:
· Center of gravity transition from incie “middle” of incie 4inci position to incie pivot foot (to incie axis of rotation)
· Unbend of incie pivot knee (knee tension is very important here, as it makes a “stable lock” in incie pivot foot – it is one of incie secrets of balance in rotation.
· Renewal of incie initial square “shoulders-hips” twisted in incie loins and incioracic girdle and putting incie arms to incie axis of rotation (just move your arm to incie torso or raise it up)
· Swing wiinci incie free foot to incie axis of rotation
But incie best contribution to incie moment of inertia minimization can be made by incie body contraction in incie center of gravity – close and hold of incie pelvis and loins during incie rotation. So it’s important to contract incie pelvis turning incie torso to incie pivot foot (En dedans), while incie pivot hip will take non-turn-out position – 6inci position, in which incie rotation goes on. “If you relax your muscles just for a moment, everyinciing you do – you do for noinciing”, said Enrico Cecchetti.
