Exercise Physiology Seminar Selective
Clinical Equine Exercise Physiology - Melissa R. Mazan, DVM, DACVIM, Director of Sports Medicine
Exciting, dynamic, practice-oriented, fun - could this really be physiology? The answer is a resounding 'Yes!' when you're talking about equine exercise physiology. Whether you're competing with your own horse, planning to be a general equine practitioner, or looking for a career in sports medicine, this selective will give you a good foundation for understanding what is happening in the exercising horse.
This seminar-style selective will review cardiovascular and respiratory function in the exercising horse, muscle metabolism, exercise and the immune system, training for speed, strength and endurance, long-term effects of training, the effects of heat and humidity in the exercising horse, nutrition for the sport horse, the use of ergogenic aids, measurement of VO2max, use of treadmills and heart monitors in practice, and will begin to explore the clinical approach to poor performance.
We will meet once a week during the fall semester for two hours. Discussion will be based on primary literature - you'll learn what journals to read, and how to read them effectively. Meeting times are flexible.
This course will also be a pre-requisite for the 4th year clinical treadmill and endoscopy elective.
