Musculoskeletal responses of 2-year-old Thoroughbred horses to early training. Conclusions.

The research study investigates how early training impacts the musculoskeletal development of two-year-old Thoroughbred horses over a course of 13 weeks. The study reports minimal clinical injury and notes significant adaptive changes in various body tissues. It suggests a need for improved diagnostic measures and further examination of how early conditioning influences musculoskeletal development.

Objective and Methodology of the Study

• The main objective of this research was to study the effects of early training on the tissues of 2-year-old Thoroughbred horses.
• However, the focus was more on adaptive changes rather than potential injuries that could be caused by such training.
• This study was extensive, running over a period of 13 weeks and used a mix of methods to garner results.

Key Findings of the Study

• The research found that there was negligible clinical injury in the tested horses.
• The types of tissues that showed adaptive responses to early training were cancellous and cortical bone, some digital tendons, and articular cartilage.
• However, the response varied among these tissues, with some reacting more significantly to the training than others.

Current Veterinary Diagnostic Measures

• The study found that existing clinical examinations and diagnostic aids used by veterinarians are insufficient for detecting early abnormalities in the metacarpo-phalangeal joint (MCPJ) cartilage, which were found in both trained and untrained horses.

Future Research Directions

• The researchers suggested that future investigatory efforts should be focused on the detection of such early changes in the MCPJ cartilage.
• Specifically, scrutinizing the exact amount of training workload a young horse can handle could provide more insight into their physiological development.
• Furthermore, the authors recommended exploring the potential of manipulating the responses of the musculoskeletal tissues by thoroughly investigating the effects of introducing conditioning exercises to horses at an early age.
