Reason: Weight boots are commonly used for Icelandic horses to increase the height of the flight arc of the forelimbs in toelt.
Objective: To show the influence of weights and toelting speed on the height of the swing phase. Materials and methods: Eight Icelandic horses (12 +/- 3 years old, 369 +/- 46 kg) were measured. Reflecting markers were placed on the dorsal side of each hoof. The motion was collected with a kinematic system (10 cameras, 120 Hz sample rate, 1.3 Mpixels resolution). The horses were ridden in toelt by 2 experienced riders on a treadmill at 2 different speeds (2.96 m/s +/- 0.30 and 4.10 m/s +/- 0.32). At each speed the horses were measured wearing no boots, light boots (170 g) and heavy boots (280 g) on both fore hooves. The measurement sequences was varied between horses. A Kolmogorov-Smirnov test was carried out to test for normal distribution of data and ANOVA for repeated measurements were used to compare differences (P<0.05).
Results: The weight as well as the speed of toelt had a significant influence on the height of the flight arc. At the lower speed, the mean +/- s.d. height was 163 +/- 55 mm, wheareas at the higher speed the mean hight was 228 +/- 60 mm. The heavy weights increased the mean height at the lower speed from 152 +/- 38 to 169 +/- 48 mm and at the higher speed from 214 +/- 60 to 245 +/- 60 mm.
Conclusions: The investigation shows that Icelandic horses can be expected to show a better toelt in competitions with weights, and ridden at a higher speed time. For muscel adaptation to occur, weights should therefore be used during competitions and training.
