Monitoring changes in skin temperature associated with exercise in horses on a water treadmill by use of infrared thermography.

This research study used infrared thermography to monitor changes in skin temperature in horses exercising on a water treadmill, providing a non-invasive way to measure muscle activity and blood flow changes. The study found significant differences in skin temperature when the treadmill was dry versus when it had water at different heights.

Objectives of the Research

In this study, the main objectives included:

• Investigating the ability of Infrared Thermography (IRT) to measure changes in surface temperature related to muscle activity and blood flow during exercise.
• Comparing the changes in surface temperature in horses during exercise on a water treadmill under three conditions: dry treadmill, water at the height of the proximal interphalangeal joint (PIP), and water at the height of the carpus (CP).
• Assessing the potential of IRT as a method for detecting muscle activity in an aquatic environment.

Design and Methodology

The research methodology involved:

• A study-size of seven horses which exercised on a water treadmill under three different conditions.
• The maximum skin surface temperature from the semitendinosus muscle region was recorded during each exercise performed at each of the three water heights.
• Utilization of IRT to measure and monitor any changes in surface temperature as an indirect measure of muscle activity and exercise-related changes in blood flow.

Findings of the Research

The key findings of the research were:

• There was a significant difference in hind limb surface temperature when exercising on a dry treadmill compared to a water treadmill at both PIP and CP heights, with higher temperatures recorded on the dry treadmill.
• There was a greater increase in hind limb surface temperature from before to maximum during exercise on treadmill with water at PIP and CP heights compared to dry treadmill, even though this increase was not statistically significant.
• No significant difference was found in hind limb surface temperature when exercising in water at the PIP height as compared to water at the CP height.
• The study concluded that IRT can effectively detect changes in muscle activity and associated blood flow in horses exercising non-invasively on a water treadmill.

Implications of the Research

The research implications can be summarized as follows:

• IRT could potentially be a viable alternative method for assessing muscle activity and temperature change in an aquatic environment, where traditional methods could be challenging.
• The findings might also be used to develop more effective training and <a href="/equine-rehabilitation-guide/" title="rehabilitation programs for equine athletes, with the potential to enhance the horse’s performance and reduce the risk of injury.
