Wie entsteht der Muskeltonus?

Zusammenfassung

„ZÄH“ & SPARSAM: Der muskuläre Ruhetonus ist kein Reflextonus, sondern ein viskoelastischer Tonus ohne elektrische Aktivität. In Ruhe steigt die Viskosität des M. erector spinae so stark an, dass er im ruhigen Stehen den Rumpf fast allein halten kann. Das spart Energie. Jeder Muskel ist thixotrop: Sobald er bewegt wird, sinkt seine Viskosität wieder. Muskeln sind wahre Energiesparer.
