hab in einem anderen forum gefragt,warum man beim bankdrücken eigentlich zeitweise recht weit oben hängen bleibt(eine position,in der man ja an sich wesentlich stärker is als knapp über der brust).hab mal folgende antwort gekriegt,vielleicht interessierts hier ja auch jemand:
Klaus,
Great question.
In a sports medicine clinic geared for evidence-based practice, we
looked at both sticking points of the bench press to better determine
our use for specific orthopaedic surgey rehab.
Hopefully, this answer will be helpful to your discussion.
When pressing the weight, quite often the humerus tends to adduct
towards the body so the elbow can be placed at a more mechanically
efficient position under the weight and forward of the shoulder. Our
EMG information showed this involves the latisimus dorsi.
The problem at the top sticking point is that with the load
practically raised, both the lat muscle and the gleno-humeral joint
don't "release" very well to allow the last few cm which are
primarily a rotation of the arm to a more efficient state of direct
load bearing.
We thought this was also why the top sticking point occurs more often
in load ranges which are more manageable but done to complete fatigue.
We began looking into this for information related to orthopaedic
rehab. We have all the right people including world class athletes
both injured and non-injured, as well as Surgeons, Physio and
Physical staff. It is informal investigation as we do not plan to
publish, however it is being administered by students from local
universities who have interest in using the same methods for their
thesis'.
Hope this information helps.
