Abstract: The purpose of the following study was to quantify mechanical changes in loading throughout the stance in both forefeet of Thoroughbred racehorses among various locomotory conditions that are normal for training and racing: speed, lead, and curve (turn or straight). Its aim was to identify changes in strains and acceleration with condition that are sufficiently large to be implicated in the causation of injuries for which the conditions are known risk factors. Ten Thoroughbred racehorses were used (2yrs, 3yrs, and 10yrs; 2 fillies, 1 mare, 1 gelding, 6 colts). High-percentage differences in loading were seen throughout the stance, with variables showing differences greater than 50% for the means and differences greater than 5% for variances. The high values of variability in loading, under relatively minor conditions, suggest that both differential changes in mean loading and the variability in loading may play key roles in the mechanical causation of specific injuries.
