However, during condition when food is not easily obtained the distance they move may increase up to 10 km (Eltringham 1999; Muller and Erasmus 1992; Tracy 1996).
An average for all road types shows this clearly with 368 glances made in the control condition and 367 made during condition (Foot-LITE) driving.
Figure 2 depicts the typical EMG traces recorded from both subjects' FDI muscles (blue and red traces) and the signal recorded from the load cell, detecting the instant at which the sphere, after its releasing, touches the floor of the container (black trace), during condition 1 (A) and 3 (B).
Throughout the experiment (during condition and rest blocks), participants performed a task to maintain fixation by pressing a button every time the fixation cross changed colour from black to red.
Further, monitoring of training sessions showed predictive value for future injuries, as horses that became injured later on had increased peak HR during condition training than horses that remained sound.
Furthermore, monitoring of training sessions showed predictive value for future injuries, as horses withdrawn because of injury later on showed already higher peak HRs during condition training than horses that stayed sound.
From the subpopulation of ten horses that were followed during condition training sessions, three horses participated at the European Championship, two horses did not meet the competition criteria, and five horses became injured.
In addition, HR measured here during condition training appeared to have predictive value for pending injuries, which is an interesting observation that, to the knowledge of the authors, has not been previously described, but one that also needs confirmation in a larger population.
However, horses that remained sound showed a significantly lower HRpeak (186 ± 12 beats/min) during condition training sessions compared with horses that were withdrawn later on from training and competition because of injury (200 ± 10 beats/min; P < 0.001), although peak and mean speed were comparable between these two groups.
During condition (1) no acoustic stimulus was presented.
