You’d be forgiven in thinking that sprint triathlon training is significantly less gruelling on your limbs than intermediate or long course training. But if your strength conditioning isn’t up to scratch, or you fail to spot problems that could lead to future chronic conditions, sprint training could prove much more punishing than you might have first thought.
If you find that your legs or feet are particularly uncomfortable after a triathlon running session, you may be suffering with overpronation. Pronation describes the rotating nature of the foot as it makes contact with the ground. Normally, the foot turns inwards slightly as it is placed on the ground, rotating as necessary to adapt to the level or inclination of the surface.
However, with overpronation, the foot arch flattens too much and effectively collapses the foot, causing the soft tissues in the foot to overstretch and joints to adjust, misalign and become loose and flexible. Obviously, this can lead to further problems such as muscle fatigue, chronic pain and even permanent injury in the lower leg. More...
