Injury incidence and locomotor behaviours in polocrosse ponies
There is currently limited information available regarding the physical demands of polocrosse and no information on the specific veterinary problems faced by polocrosse ponies in the United Kingdom. Polocrosse requires the ponies that compete to perform rapid acceleration, sharp turns and sudden halts. The study aim was to explore the injury incidence and type of injury, between the three positions played by polocrosse ponies. Injuries that resulted in withdrawal of a pony during outdoor tournaments in the UK over the 2015 and 2016 seasons were recorded. In addition, GPS data and locomotor behaviours were recorded during winter league tournaments in 2017 and compared between the different position ponies. Ponies that played in the defence position were significantly more likely to become injured (P<0.001) with lameness being the most common cause for withdrawal (P<0.001). Ponies playing in the attack position achieved the fastest speeds and covered the furthest distance. Defence ponies performed significantly more abrupt halts (P=0.007), walk to gallop transitions (P=0.017) and sudden changes in direction (P=0.01) than midfield ponies and more of each manoeuvre than attack ponies, although this was not significant. It is important that the physical demands placed upon polocrosse ponies are investigated further; this will allow identification of injury risk factors, inform training programmes and improve the performance and welfare of the horses involved.
