This study analyzes the impact of cable exit angle on the accuracy of velocity measurements in linear position transducers (LPTs). Two models, Vitruve and Chronojump, were evaluated at five cable exit angles (0°, 10°, 30°, 60°, and 90°) using a 2.5 kg mass in free fall. Five measurements were taken per angle, and data were analyzed using MANOVA.
The results showed no significant differences in velocity measurements due to cable exit angle (p > 0.05), but there were significant differences between LPT models (p = 0.005), with Vitruve recording higher velocities than Chronojump. This challenges the recommendation to limit cable deviation to 2° to avoid friction-related measurement errors.
These findings suggest that cable exit angles within the 0° to 90° range do not compromise the accuracy of velocity measurements in the evaluated models. This may facilitate the implementation of LPTs in training environments by reducing placement restrictions and optimizing their use in velocity-based training (VBT) protocols.
