Track & Field Basic Movements
Running
Running or sprinting consist in a series of functional movement, link and well sequenced to achieve performance. All the desirable movements are executed in the sagital plane of the body. Deviations from the orientation and amplitude of those movements can be attributed to weak-long problem with a pair of joint mover muscle. The list of the movement appear in the figure below. Note that some of the movements for some joints are not listed. Not that those muscles do not participate to the running movment but they are not producing movement at the joint level. Rather, they contract isometrically to stabilize the joint. If some of the movements not listed appear in the execution, it should be consider as a dysfunction and address. Keep in mind that the mobility or stability of the faulty joint might be adequate and that the dysfunction come from motor control, the athlete not timing or not using the movement correctly.
Common Dysfunction
Hip External Rotation: Makes the foot point away from the centre of the body.
Low Knee: Flexion of the hip is not ample enough. Note that it
will be more ample for sprinting than running.
Ankle Pronation: Foot goes into eversion at contact with the
ground sometimes forcing the knee to move inside and the hip to go into internal rotation.
Javelin Throw (delivery)
The delivery of the javelin throw is a very complex movement made of many functional movement, link and well sequenced to achieve performance. The movements are at first executed in the coronal (frontal) plane. The hips and shoulders then rotate to complete the action in the sagital plane. Deviations from the orientation and amplitude of those movements can be attributed to weak-long problem with a pair of joint mover muscles. The list of the movement appear in the figure below. Note that some of the movements for some joints are not listed. Not that those muscles do not participate to the throwing movment but they are not producing movement at the joint level. Rather, they contract isometrically to stabilize the joint. If some of the movements not listed appear in the execution, it should be consider as a dysfunction and addressed. Keep in mind that the mobility or stability of the faulty joint might be adequate and that the dysfunction might come from motor control, the athlete not timing or not using the movement correctly.
