If your ankles do not have the same range of motion or strength – will that affect your body?
Maybe there is no pain – but if you do not move and stabilise the same on each side you will compensate at your knee or at your hip or at your lower back in order to produce the action. You will possibly not travel the hip through straight and will swing more on one side – this will create a shortening of muscles in one of your hip flexors. Which will then effect your performance in your sport – either the power of your stride at take off or in the stability at the landing, at any rate the balance will be affected because of the asymmetry of the action.
This will have an effect on all sports – cycling – there will be a twist in the lower back as the foot is pushed into the down stroke.
In running as the leg travels behind the body and then through – in the image below see James in the middle his hip twists to his left and his shoulders to his right, and he is bending to the left at the waist, with an inward collapse of his knee – he is loosing energy in the movement of his body. Merritt on the other hand is solid – his shoulders and hips are square. His limbs are powering him forwards.
Merritt may not be quicker – because he is heavier – but he will sustain less injury and have a longevity in his sport through lack of discomfort.
In horse riding where one is “sitting” but one needs to be straight.
If you see pictures of yourself crooked – it may not be due to your “tool” or your ability – it may be due to your internal/intrinsic biomechanics. So get it checked out.
