Heart rate responses during acclimation of horses to water treadmill exercise.

The research studied horses’ heart rate responses during acclimation to water treadmill exercise, with and without sedation during initial exposure. It found that acclimation requires a minimum of two 15-minutes nonsedated acclimating runs, with previous water treadmill exercise experience considered significant prior to data collection for physiological and biomechanical parameters.

Objective and Methodology

• The research aimed to determine heart rate responses in horses while they become familiar with water treadmill exercises, either with sedation during the first exposure or without it.
• Fourteen horses were randomly assigned into two groups (Group A – sedated, and Group B – non-sedated). All horses were made to exercise daily on a water treadmill for four days, with each session lasting 15 minutes.
• The horses in Group A were administered a sedative (romifidine) 10-15 minutes before the start of the first acclimating run.

Findings

• The point at which a horse was considered acclimated was identified when it reached a threshold heart rate value.
• The results revealed that both Group A and Group B reached the threshold heart rate values around the 6th minute of the 4th and 3rd run respectively. The heart rate values were 72.8 beats/min for Group A and 78.7 beats/min for Group B.
• It was also observed that there was no significant difference in the time taken to reach the threshold between both groups.

Conclusion

• Acclimation to water treadmill exercise requires a minimum of two 15 minute non-sedated acclimating runs.
• The study found that while sedation can be used to prevent panic in horses during their first exposure to water treadmills, it doesn’t affect the time taken to acclimate.
• Furthermore, the researchers concluded that previously gained experience with water treadmill exercise is an important consideration before collecting physiological and biomechanical data.
• Indicating the need for further study, the research highlights the necessity for detailed exploration into the physiological and biomechanical responses before making suggestions to include this mode of exercise in <a href="/equine-rehabilitation-guide/" title="rehabilitation programs.
