Common problems – the horse In canter the rider is aiming to maintain a good rhythm ensuring it maintains the three beat pattern and engages the hind quarters by moving the centre of gravity backwards (see diagram, below left). In some cases riders may ask the horse to perform movements within the canter, such as a flying change; or lead variations such as counter canter which test the horse’s balance and limb co-ordination. A poor canter can be caused by: ● Lack of balance/suppleness ● Loss of rhythm ● Incorrect strike off ● Disunited stride ● Incorrect bend ● Stiffness ● Muscle asymmetry ● Skeletal maturity Common problems – the rider The rider plays a large part in determining a horse’s way of going. Problems may include: ● Leaning forward – this encourages the horse to go on to his forehand and increases weight distribution on to the forelimb, which then prevents hind limb engagement. ● Leaning back – causing the rider to be behind the movement. This can affect the athleticism of the horse by preventing elastic use of the back. ● Sitting to one side – this will also affect the canter as the weight distribution is uneven. This not only affects the canter but can also affect muscle development. www.yourhorse.co.uk Leaning back is a common problem in canter. In all cases, the addition of a rider alters the movement of the horse (kinematics) and the ground reaction forces (GRF) with changes being more pronounced in the forelimb. This happens during all gaits, so can affect the canter. All of these rider faults can be identified with the use of rider analysis (see page 108). Improving your canter – gait and rider analysis To help maintain the balance of the horse in canter the rider should aim to sit upright so his/her centre of gravity is directly above that of the horse, encouraging engagement of the hindquarters. Many changes to the canter gait (caused by horse or rider) are extremely subtle and cannot always be seen, so they can’t always be assessed accurately. The human eye can capture only 15 frames per second; but the cameras used in gait analysis can capture 50-1500 frames per second, providing a greater amount of information at any one time. As well as the limitations of the human eye, visual assessment of the gait is also plagued with the inherent risk of subjectivity. Case study Riding advice Henry Boswell is a young dressage rider who’s used biomechanics and Equianalyis… “I found out about Centaur Biomechanics and Equianalysis through World Class Start and Potential, which I’m on. It plays a big part in our training and any discipline can benefit from it. “If I hadn’t done it through Start and Potential I’d definitely do it anyway as it’s opened my eyes – nothing quite highlights how you ride better than seeing it played back to you afterwards on a big screen. You can pick up on something you may have felt and see it straight away. “The rider screening has really helped my test riding, especially how I prepare for movements. It’s shown me that if I don’t prepare for movements then the first four strides can suffer. “I also use the horse screening. One of my young rider horses had soundness issues, no one knew what it was, not even the vets. Then we had the screening done and it threw up a slight problem with the coffin joint. “The rider analysis is a great tool to help you see how you ride and pinpoint where issues are coming from. I do it about three-four times a year and it’s really helpful to have your trainer with you.” ➜ Your Horse 107 23
