Training load quantification in the equine athlete
The rating of perceived exertion scale (RPE) is validated as a proxy measure for the physiological workload in human
sport alongside the Edwards internal training load calculation. Both methods are validated to monitor training load in human athletes. This study investigated if these methods could potentially offer a simple and repeatable measure of the workload in equine training regimens.
Heart rate data were obtained with heart rate monitors during one single exercise session from 32 horses across a range of equestrian disciplines with experienced riders and trainers, on different surfaces. Additionally, the Edwards training load methodology was applied, which is an algorithm using the duration of time spent within five pre-defined heart rate zones, which then will be factored to obtain an internal training load measure (see figure 2). The last parameter obtained was the rating of perceived exertion of the horse during the exercises session, which was collected from the riders and trainers. This measurement thus reflecting their perception of the horses’ exertion on a scale of 10 for the entire sessions. This rating was then multiplied by exercise duration to determine session perception of the training load.
Statistically significant correlations between the heart rate measurements and the calculated internal heart rate were found for both riders’ and trainers’ ratings of training load in all types of sports-horses. The results suggest that the rating of perceived exertion scale and the Edwards internal training load calculations can be used as inexpensive and easy tools to quantify training load and objectively assess progress in training.
In this video, the rating of perceived exertion and its practical application is explained on a scale from 0 to 20.
Expert opinion by Isabeau Deckers
This study showed that the 'rating of the perceived exertion' scale and the Edwards internal training load calculation are both suitable tools for every rider/ trainer at all levels to assess training intensity for equine athletes. A consistent approach to both tools, adjusted by the related professionals working with the horses, will benefit the horses' performance and welfare, as it can prevent both over and undertraining. Further research is warranted in the exploration of optimal heart rate zone allocation for specific disciplines and breeds, alongside the application of training load monitoring within equestrianism.
