Heart rate monitors are an emerging tool in horse sports, helping to optimize training and enhance fitness. Widely used by human athletes, equine-specific devices are now increasingly accessible to riders, horse owners, trainers, and veterinarians.

Research suggests many performance horses aren’t trained adequately. Training intensity often doesn’t match competition demands, which can lead to underperformance during competitions, increased stress, and poor exercise recovery.

Overtraining is another concern, contributing to musculoskeletal injuries, stress, impaired immune function, poor competition readiness, and even long-term health issues for horse.

Heart rate monitors address these issues by providing real-time feedback on a horse’s exertion levels. This allows trainers to precisely tailor workout regimens, ensuring horses are trained at the right intensity to improve fitness without risking overexertion.

The use of heart rate monitors is crucial in striking a balance between a horse’s welfare and peak performance. [1] This article explores the science behind heart rate monitors for horses, the benefits of using these monitors, and provides an overview of the different types available in the market.

Heart Rate Monitors for Horses

An equine heart rate monitor is a device used to continuously measure and display a horse’s heart rate, typically expressed in beats per minute (bpm). These sensors usually consist of a strap or electrode system that is placed on the horse’s body, often around the girth area or under the saddle pad.

The sensor detects the electrical activity of the horse’s heart and transmits this data either wirelessly or through a wired connection to a display device, such as a watch, a handheld monitor, or a smartphone app.

The main benefit of using a heart rate sensor is to ensure that the horse trains at an appropriate intensity to improve physical conditioning and avoid overexertion. Achieving the right training intensity is important so horses can safely attain their performance goals.

Training Intensity

Research shows that many performance horses are not trained at an intensity level that matches their competitions. [2] This mismatch can lead to various challenges, including inadequate preparation for the demands of competitive events.

A study involving 4-star eventing horses reported an average heart rate of 161 bpm during training sessions compared to 210 bpm during competition. [2][3] Eventers also trained at much lower speeds than those encountered during competitions. [4]

Although some of these performance differences can be explained by stress responses to new environments, this data indicates that training workloads do not match competition intensity. Training at a lower intensity might not sufficiently condition the horse’s cardiovascular system, muscles, and mental readiness for the rigors of competition, potentially impacting their performance and increasing their risk of injury.


While we want to ensure horses are sufficiently trained for competition, it’s equally important to guard against overtraining. Excessive training at a high intensity can increase the risk of injuries due to excessive strain on muscles, tendons, and joints.

Horses with overly intense training regimens may also experience a decline in performance, poor exercise recovery, increased risk of illness or infection and weight loss[5]

By monitoring a horse’s physiological response to exercise, heart rate monitors help to find a balance in training regimens that promote readiness for competition while protecting the horse’s health.

Five Benefits of Heart Rate Monitors for Horses

In the following section, we explore the top five benefits of using heart rate monitors for horses, highlighting how they can enhance performance and support the health of equine athletes.

1) Personalized Training

Every horse is unique, and responses to training vary. Measuring your horse’s heart rate provides an objective way to assess their cardiovascular fitness in response to different exercises challenges

By monitoring the consistency of your horse’s heart rate during training, you can gauge when your horse has adapted to an exercise level and is ready for the next challenge.

This is particularly important for horses returning to work after an injury or those just starting under saddle. Heart rate monitors enables trainers to personalize training regimens to best achieve a horse’s performance goals.

2) Improved Conditioning

Spending more time training at the correct heart rate will help to enhance a horse’s overall fitness.

Fit horses exhibit lower heart rates during high-intensity work, enabling them to sustain exercise for durations periods. This improved endurance directly translates to prolonged high-level performance.

Moreover, monitoring your horse’s heart rate during post-exercise recovery provides a key indication of fitness level. A rapid return to resting heart rate (ideally reaching 120 bpm or less within 2 minutes post-exercise) signifies a high level of fitness and indicates the horse’s readiness for subsequent training or competitions. [7]

3) Reduced Risk of Injury or Illness

Training with heart rate monitor can help you protect your horse’s health and determine if your horse is fit enough to enter a competition.

Research suggests that horses with superior fitness parameters, including lower heart rates during exercise training, are more likely to remain sound and less prone to withdrawal from competition. [4]

In hot weather conditions, heart rate monitors assist trainers and riders in adapting training schedules to reduce the risk of heat stress and heat stroke.

4) Identifying Stressors

Heart rate monitors serve as critical tools for detecting stress in horses that may indicate anxiety, pain, or discomfort not immediately apparent through behavior alone.

Research shows that an unexplained increase in heart rate, not linked to physical exertion or temperature, can be a sign of pain or anxiety in horses. [8]

For example, studies show that horses exhibit elevated heart rates before entering a show jumping arena or during air or road transportation. [1][9] These findings demonstrate how heart rate monitors can help us understand a horse’s emotional and physical well-being in different environments.

5) Real-time Training Feedback

Heart rate monitors provide immediate and accurate feedback during training sessions, detecting changes in heart rate within 5 seconds after an increase in exercise intensity. [10]

This real-time information allows the rider to determine the horse’s exertion level, ensuring they are working within the correct training zone. Optimizing the time spent in different training zones is an important part of designing a training plan.

Training Zones for Horses

Training zones for horses are defined heart rate ranges that correspond to different levels of exercise intensity. These zones help in structuring a horse’s training program to optimize conditioning, performance, and recovery.

During exercise, a horse’s heart rate increases to deliver oxygen and energy to the muscles. This increase in heart rate is directly proportional to the exercise’s intensity, enabling the categorization of heart rates into distinct zones.

These zones, numbered from 1 to 5, represent increasing exertion levels and types of activity.

Zone 1 indicates very light work, such as walking and trotting, which only slightly raises the heart rate. Zone 5 represents the maximum level of work, characterized by a significantly higher heart rate reflecting peak intensity of exercise.

Guide to Training Zones

Zone Heart Rate Type Training Goal Example Exercises
Zone 1
(Very Light)
< 140 bpm Aerobic Low-intensity exercise for overall health and active recovery. Recommended for warm-ups, horses entering work or horses recovering from injury. Walk & Trot
Zone 2
>140 – 160 bpm Aerobic Improves basic endurance and helps prepare for higher-intensity exercise. Recommended for longer, low-intensity endurance training. Walk, trots and slow canters
Zone 3
160 – 170 bpm Aerobic Improves muscle strength and builds the ability to sustain moderate exercise for longer periods of time. Quick canter intervals mixed with longer trots. Moderate hill work or jump training
Zone 4
170 – 190 bpm Anaerobic Improves endurance at higher speeds and increases the capacity of muscles to burn energy without oxygen. Intervals of fast canters and gallops. Moderate hill work
Zone 5
> 200 bpm Anaerobic Improves strength and stamina – the amount of time the horse can work at their maximum output. Should only be trained with pre-conditioned horses. Fast gallops, intensive hill work
