Physical exercise significantly impacts horses' intraocular pressure (IOP) and ocular temperature (OT), which correlate with rectal temperature (RT). These measurements may indicate athletic fitness in horses during exercise.
Area of Science:
- Equine physiology
- Ophthalmology
- Sports medicine
Background:
- Understanding physiological responses to exercise is crucial for athletic horse management.
- Ocular variables like temperature and pressure are often overlooked indicators of physiological stress.
Purpose of the Study:
- To investigate the impact of physical exercise on ocular temperature (OT) and intraocular pressure (IOP) in horses.
- To correlate these ocular changes with rectal temperature (RT) before and after exercise.
- To compare exercise responses in the morning (a.m.) versus afternoon (p.m.) sessions.
Main Methods:
- Collected data from 14 healthy Italian saddle horses undergoing a jumping course.
- Measured ocular temperature (OT), intraocular pressure (IOP), and rectal temperature (RT) before and after exercise.
- Utilized two-way repeated-measures ANOVA and Bland-Altman analysis for statistical evaluation.
Main Results:
- Intraocular pressure (IOP) showed a statistically significant effect of time (before vs. after exercise).
- Rectal temperature (RT) and ocular temperature (OT) were significantly influenced by time of day and experimental conditions (a.m. vs. p.m.).
- A strong agreement was found between rectal temperature (RT) and ocular temperature (OT) values.
Conclusions:
- Increased body temperature during exercise correlates with variations in intraocular pressure (IOP).
- Ocular temperature (OT) and intraocular pressure (IOP) can serve as potential indicators of physical fitness in athletic horses.
- Time of day influences thermoregulatory responses and ocular parameters during exercise.
