This Horse Race Betting Levy Board funded grant focused on improving quality of life for race horses, and understanding why some horses are susceptible to chronic tendinopathy, the incidence of which increases with ageing. We established how the main chages to horse tendon with age occured specifically within a certain part of the tendon matrix - the soft material linking together fascicle called the interfascicluar matrix. Based on our findings, we have achieved further funding to investigate this in greater detail.
