Razvoj sistema za merjenje telesnih asimetrij s pospeškometri. (Slovenian)

In sports, acute and chronic injuries of athletes are common despite the growing knowledge and interest in the preventive activity in the sports practice. One of the main causes of injuries in athletes are their body asymmetries, which can only be dealt with if properly quantified. Despite the availability of several measuring systems, the majority of them do not allow segmental measurements and those that do are not portable. To solve the issue, a portable measuring system to measure the body asymmetries of the lower part of the human body was designed and manufactured. It measures and stores the data acquired by six accelerometers attached at the foot, tibia and pelvis of the human both legs. The system is compact, lightweight, portable and allowing a local data storage on the measuring device itself and triggering external signal to start the data acquisition. The system is driven by a sophisticated microcontroller that ensures data sampling at a high sampling rate. Results of a preliminary experimental system evaluation and validation are positive and encouraging for its further development and enhancement. [ABSTRACT FROM AUTHOR]

V športu so akutne in kronične poškodbe pogoste kljub naraščajočemu znanju in zanimanju za preventivno dejavnost v športni praksi. Eden izmed glavnih vzrokov za nastanek poškodb pri športnikih so telesne asimetrije, s katerimi se je mogoče spoprijeti le, če jih pravilno izmerimo. Obstaja več sistemov, s katerimi lahko merilno telesne asimetrije, vendar večinoma ne omogočajo segmentnih meritev, medtem ko tisti, ki to omogočajo, niso prenosljivi. Za premostitev te prepreke smo načrtovali in izdelali prenosni merilni sistem, ki omogoča medenje telesnih asimetrij spodnjega dela človeškega telesa. Merilni sistem meri in shranjuje podatke iz 6 pospeškometrov, ki so pritrjeni na stopalo, golenico in medenico obeh spodnjih okončin. Sistem je kompakten, lahek, prenosljiv, omogoča lokalno shranjevanje podatkov na merilni napravi in ima možnost uporabe zunanjega sprožitvenega signala za začetek vzorčenja podatkov. Sistem poganja sofisticiran mikrokrmihiik, ki zagotavlja vzorčenje podatkov pri visoki frekvenci vzorčenja. Niz preliminarnih poskusov je dal pozitivne rezultate evalvacije in validacije sistema, kar spodbuja nadaljnji razvoj in izboljšavo sistema. [ABSTRACT FROM AUTHOR]
