Abstract

Opisana je prisutnost asimetrije kretanja (AK) sportskih konja u treningu. Međutim,
utjecaj treninga na AK nije procijenjen. Ciljevi su bili procijeniti AK prije i nakon treninga s
hipotezom da će se s utjecajem treninga AK promijeniti. Vertikalni pomak (VP) glave, grebena
i zdjelice izmjereni su kod 14 konja (srednja dob od 11,2 godine) tijekom treninga za koje je
vlasnik smatrao da nisu hromi. Inercijski senzori postavljeni su na glavu, greben i zdjelicu za
mjerenje asimetrija tijekom kasa neposredno prije i nakon treninga gdje je bilo potrebno
izmjeriti najmanje 25 koraka. Trening je standardiziran radi homogenizacije populacije u obliku
flat work vježbi u trajanju od 45 minuta. Ispitane su relativne i apsolutne razlike između
minimuma i maksimuma vertikalnog pomaka. Ukupna srednja razlika relativne vrijednosti VPa nakon treninga pokazala je smanjenje od -4,9 mm (u rasponu od -11,9 mm do -1,3 mm) sa
značajnim promjenama samo za parametre senzora glave (P= 0,03; 0,02). Ukupna srednja
razlika za apsolutne vrijednosti VP-a nakon treninga bila je 8,6 mm (u rasponu od 4,6 mm do
14,6 mm), a uzimajući u obzir definirane pragove senzora, primijećeno je značajno povećanje
parametara amplitude UpD svih senzora (P= 0,02; 0,05; 0,05). Dokazano je da trening utječe
na AK kod konja. Asimetrija je bila manje izražena na senzorima glave. Rezultati ukazuju na
moguće smanjenje boli ili mehaničkih abnormalnosti s obzirom na razlike u fazi podizanja
udova nakon treninga.

Abstract (english)

The presence of movement asymmetries (MA) in horses in training has been described.
However, the training influence on MA has not been evaluated. Objectives were to evaluate
MA before and after the training with a hypothesis of change in degree of asymmetry. Vertical
head, withers and pelvic asymmetries were measured in 14 horses (mean age of 11,2 years) in
training perceived not lame by the owner. Inertial sensors were mounted at the poll, withers and
pelvis to measure gait kinematics during straight trot in hand immediately before and after
training where a minimum of 25 strides were assessed. The training was standardized in form
of flat work exercises, duration of 45 minutes. Raw and absolute differences between vertical
displacements (VD) minima and maxima were tested. The overall mean difference in raw VD
after training showed a decrease of -4,9 mm (means ranging from -11,9 mm to -1,3 mm) with
significant changes only for poll parameters (P= 0,03; 0,02). The overall mean difference in
absolute VD after training was 8,6 mm (means ranging from 4,6 mm to 14,6 mm) and
considering normal thresholds a significant increase was observed in the maxima parameters of
all sensors (P= 0,02; 0,05; 0,05). It is proven that training influences MA measures in horses.
The asymmetry was less pronounced on poll parameters. The results indicate a possible
decrease in pain or mechanical abnormalities considering differences in limb propulsion due to
training.
