The effects of running gait cycle with and without a knee restrictor
The development and patterns of overuse injury in running are interesting from a biomechanics perspective. Clinical data reveals that a few runners are repeatedly injured while others are injured infrequently (Cavanagh 1990). A unilateral pattern of injury development is accepted in that injury frequently develops and grows in only one side, in spite of the cycle nature of running. In consideration these observations raise the question whether some individuals are inclined to or at greater risk of injury (McGinnis 1999). Patterns of running injury suggest that the risk of injury is very much related to the interactions among the individual, the task, and the environment, or intrinsic and extrinsic factors.
Gymnastics provides an example of how biomechanics may aid in reducing injury. The Unites States Gymnastics Association funded research concerned with the impact forces that gymnasts experience when landing from stunts and the strategies

The camera that was used to record the participant was a Panasonic NV-GS500 camera, the position of the camera was located on a static tripod at a distance of 75cm from the floor to the centre of the lens. The camera was placed approximately 6 metres away from the treadmill belt (H-P-Cosmos-KistlerGaitway II S, H-P-Cosmos Sports and Medical/Kistler Instrument Corporation), along the peripheral vision which was set accordingly towards the change of activity. The frame rate was confirmed at being 25 frames/50 fields per second whilst the shutter speed was set at 1/750 and this was done securely by using Dartfish software. In order to calibrate the following was done a metre long ruler was positioned both vertically and horizontally midway of the treadmill belt, this was done preceding the experiment to ensure the scale factor can be established at a later time when completing
