Monty Roberts’ Public Demonstrations: Preliminary Report on the Heart Rate and Heart Rate Variability of Horses Undergoing Training during Live Audience Events

Abstract

Simple SummaryMonty Roberts is a famous horse trainer, commonly referred to as a ‘horse whisperer’, who shares his training methods all over the world, including through large public audience events. These events have the potential to compromise the horse’s welfare since the horses have usually been transported to the event on the day and stabled in an unfamiliar environment before being used in demonstrations watched by hundreds of people. This paper describes the opportunistic collection and analysis of heart rate (HR; beat-to-beat intervals) and heart rate variability (HRV) of horses being trained during Monty Roberts’ public demonstrations within the United Kingdom. HR and HRV measured during the demonstrations were lower (indicative of an increase in heart rate as measured in beats-per-minute) than recordings within the stable and consistent with low-moderate exercise intensities used during training. The HR and HRV during a specific training method known as “Join-up®” were comparable to other methods of training used by Monty Roberts during public demonstrations. In conclusion, training of horses during public demonstrations is a low-moderate physiological, rather than psychological stressor for horses, with the stress response comparable or less than those previously reported in the literature for horses being trained outside of public audience events. Furthermore, we found no evidence that Join-up® alters HR and HRV in a way to suggest that this training method negatively affects the psychological welfare of horses.AbstractEffective training of horses relies on the trainer’s awareness of learning theory and equine ethology, and should be undertaken with skill and time. Some trainers, such as Monty Roberts, share their methods through the medium of public demonstrations. This paper describes the opportunistic analysis of beat-to-beat (RR) intervals and heart rate variability (HRV) of ten horses being used in Monty Roberts’ public demonstrations within the United Kingdom. RR and HRV was measured in the stable before training and during training. The HRV variables standard deviation of the RR interval (SDRR), root mean square of successive RR differences (RMSSD), geometric means standard deviation 1 (SD1) and 2 (SD2), along with the low and high frequency ratio (LF/HF ratio) were calculated. The minimum, average and maximum RR intervals were significantly lower in training (indicative of an increase in heart rate as measured in beats-per-minute) than in the stable (p = 0.0006; p = 0.01; p = 0.03). SDRR, RMSSD, SD1, SD2 and the LF/HF ratio were all significantly lower in training than in the stable (p = 0.001; p = 0.049; p = 0.049; p = 0.001; p = 0.01). When comparing the HR and HRV of horses during Join-up® to overall training, there were no significant differences in any variable with the exception of maximum RR which was significantly lower (p = 0.007) during Join-up®, indicative of short increases in physical exertion (canter) associated with this training exercise. In conclusion, training of horses durin...

The effect of the combination of various training methodologies in horse training on the learning performances of Arabian horses

“…Lesimple (2020), states that heart rate is an indicator of the welfare of horses. In a study of Loftus et al (2016), when comparing the HR of horses during Join-up to overall training, there were no significant differences. Similar to our research results, Physick-Sheard et al (2000) pointed out that the increase in HR may be due to physical exertion and/or an increase in psychological stress.…”

Building Bridges between Theory and Practice: How Citizen Science Can Bring Equine Researchers and Practitioners Together

“…However, research into horse training, management and behaviour can be prohibitively expensive. Small-scale studies, comparing one training or management method with another [5] are useful, but often have a narrow focus [6]. These factors of scale and focus combine to limit the generation of helpful, evidence-based, practical applications for horse riders and handlers.…”

An analysis of equine round pen training videos posted online: Differences between amateur and professional trainers

“…Natural horse (NH) training methods are popular among amateur and professional horse trainers [ 1 ] and have been the subject of recent scientific enquiry [ 2 , 3 , 4 ]. One school of thought is that NH methods are more humane and result in a better human-horse relationship than other methods [ 2 , 5 ].…”

“…One school of thought is that NH methods are more humane and result in a better human-horse relationship than other methods [ 2 , 5 ]. However, there is considerable variation in the specific training techniques applied by NH trainers [ 1 , 6 , 7 , 8 , 9 , 10 ] and in the descriptions they attract in the scientific literature [ 2 , 5 , 11 , 12 , 13 ].Nonetheless, common to all the NH methods reported in the scientific literature is the use of a training technique known as the “chase-away” [ 4 , 7 , 14 ] which takes place in a circular pen known as a round pen.…”

“…Although RPT is promoted as humane and effective, there are currently limited studies detailing a typical RPT session and the response of horses to this training method [ 3 , 4 , 5 , 7 , 8 , 9 , 12 , 21 , 22 , 23 ]. RPT is advocated by professional NH trainers as part of foundation training (i.e., prior to the first saddling and riding of unstarted horses) or to retrain horses with undesirable behaviours [ 7 , 8 , 9 , 21 ].…”
