Here is how. The symmetry and regularity metrics are found in your analytics tab (Pro offer) ### 1. Regularity - Regularity can be defined at trot or canter. - It is an indicator of the similarity of a stride with the previous one. - Two consecutive strides will never be perfectly identical in length or duration. - In a nutshell, regularity studies the variation in stride length and stride frequency of a stride with the previous one. *The more the strides are different from each other, the less regular the regularity, the more energy the body expends to maintain the pace.* A lack of regularity leads to a lack of efficiency and therefore to more effort for the horse. **As a general rule, successful horses have great regularity data.**  - Regularity is not a fixed value but depends on many parameters. - It increases with age and training and is a witness to the improvement of a horse’s coordination. - At high speed, it decreases because it is more difficult for the horse to maintain a smooth and clean stride as he approaches his limits. ### 2. Symmetry - Symmetry can only be defined when trotting. - It compares the movements of the right diagonal with the left. - In canter, the two diagonals do not perform the same movements, so the symmetry cannot be calculated. - Symmetry quantifies the spatial and temporal variation between the movement of the right and left diagonal. - Ideally, both diagonals cover the same distance and result in the same time. *Like regularity, symmetry improves with age and training which will erase natural asymmetries.* ### 3. How to analyse the figures ? - Regular monitoring of symmetry and regularity allows you to get to know your horses better, to check their progress or to detect pain. - Keep in mind that a horse is never perfectly symmetrical or regular. - A stride will never replicate itself in all points identical due to the many physical parameters to be taken into account. It is a question of comparing a horse with itself or with another and not with an arbitrary value. *Well conducted training should improve the symmetry of the horse by promoting harmonious musculature and trying to erase natural disparities.*  - It is therefore relevant to monitor the evolution of these two parameters. It allows to ensure that the work is balanced and to detect early possible injuries. ![](https://training.arioneo.com/wp-content/uploads/2021/07/Sans-titre-2-1.png) - In the event of injury, to relieve the painful limb, the horse will transfer weight to the healthy limbs which reduces regularity and symmetry. - Any significant variation from one session to the next is a warning to the trainer. *Comparing one stride to another and the movement of the 4 limbs allows us to quantify the harmony and symmetry of the musculature of athletic horses.* *Monitoring these parameters provides a lot of information on the work carried out but can also provide information on other problems.* - [USE OF THE SENSOR](https://knowledgebase.equimetre.com/en/use-of-the-sensor?hsLang=en) - [THE EQUIMETRE APP](https://knowledgebase.equimetre.com/en/the-equimetre-app?hsLang=en) - [FIRST STEPS WITH EQUIMETRE](https://knowledgebase.equimetre.com/en/first-steps-with-equimetre?hsLang=en) - [THE EQUIMETRE PLATFORM](https://knowledgebase.equimetre.com/en/the-equimetre-platform?hsLang=en) - [FIRST STEPS IN THE ANALYSIS](https://knowledgebase.equimetre.com/en/first-steps-in-the-analysis?hsLang=en) - [GOING FURTHER IN THE ANALYSIS](https://knowledgebase.equimetre.com/en/going-further-in-the-analysis?hsLang=en#main-content) - [Dashboard Vet - ECG analysis platform](https://knowledgebase.equimetre.com/en/going-further-in-the-analysis?hsLang=en#dashboard-vet-ecg-analysis-platform) - [TECHNICAL SUPPORT](https://knowledgebase.equimetre.com/en/technical-support?hsLang=en) [![Chill listening crop-3](https://knowledgebase.equimetre.com/hs-fs/hubfs/Logo_ARIONEO_sans%20signature_N.png?width=30&height=24&name=Logo_ARIONEO_sans%20signature_N.png "Chill listening crop-3")](http://horselab.com) KNOWLEDGE BASE EQUIMETRE Copyright © 2026, ARIONEO
