Abstract

U ovom su radu, na primjeru čučnja, ispitana opterećenja Ahilove tetive u mirovanju. Izračunata su opterećenja za čučanje na prstima i na punom stopalu. Kroz rad opisana su mehanička svojstva Ahilove tetive, spomenute su ozljede i liječenja tetive, opisana je metoda i provedeno izračunavanje opterećenja u Ahilovoj tetivi te su opisane prednosti i nedostaci utvrđene metode.

Eksperimentalni dio provodio se pomoću Elite sustava u Laboratoriju za biomehaniku na Kineziološkom fakultetu u Zagrebu, a dobiveni podaci (koordinate položaja markera) korišteni su u daljnjoj analizi. Pomoću Zebris platforme dobivena je sila u središtu pritiska stopala što nam je potrebno za daljnji proračun. Za numerički dio postavljen je model za 2D analizu, služeći se statikom sustava krutog tijela i dobivene su sile u Ahilovoj tetivi.

Abstract (english)

In this thesis, on the example of a squat, loads of the Achilles tendon at rest were examined. Squat loads on toes and at full foot were calculated. Also were described the mechanical properties of the Achilles tendon, injuries and treatments of the tendon, the method is described and the load calculation performed in the Achilles tendon and advantages and disadvantages of the established method.

The experimental part was carried out using the ELITE system at the Biomechanics Laboratory at the Faculty of Kinesiology in Zagreb and the obtained data (marker position coordinates) were used in further analysis. With Zebris platform, the central pressure force was obtained, which is needed for further calculation. A model for 2D analysis was created fot the numerical part, using the static of the rigid body system and forces, that occur in the Achilles tendon, were obtained.
