Definitions
- This invention relates to a uni-lateral sled and force measurement device, apparatus and system.
- Unbalanced unilateral (single leg) horizontal force is linked to various type of injuries include hamstring, groin injury, hip flexor, knee ligament and lower back. Understanding unilateral horizontal force is also useful for training performance and monitoring. Injuries above commonly occur in athletes of many popular sport events in which high speed sprinting is frequently performed, including track and field events, football, and rugby. Injuries such as hip injury has a very high recurrence rate. In the English professional soccer/football leagues, hamstring strain injury reoccurred between 12% to 48% of the players. In addition, the persistence of the recurrence was reported to continue for many weeks after returning to play with cumulative recurrence risk of 31%. In many cases, hamstring injuries have led to considerable time lost from training and competition, which result in financial loss and diminished athletic performance.
- An example of an instrumented treadmill is the Woodway which is between $30,000 to $50,000 NZD and it does not accommodate change in angle and it is often considered biomechanically different to over-ground sprinting.
- the attraction of the proposed device is not only injury prevention but also training performance and monitoring.
- the current solutions for unilateral force, in the context of training performance and monitoring, suffers from the same limitations as above—high cost, limited portability, and require specialised knowledge to operate.
- Instrumented treadmills Devices used for assessing unilateral force production include instrumented treadmills, pressure sensors in shoes, accelerometers and multiple in-ground force plates.
- Instrumented treadmill's advantages include the ability to assess force production for several steps and accurate and reliable data. Instrumented treadmills, however, are costly, and require highly specialised knowledge for data analysis. Pressure sensors are easy to use, however have not proved to be useful for this purpose. Accelerometers are easy to use but have not been proven to be useful for unilateral force assessment and require time to process and analyse the data. Only a few facilities in the world have enough in-ground force plates in a row to make assessment possible but the cost of a sufficient number of in-ground force plates is in the magnitude of millions.
- the isometric mid-thigh pull is widely used as a total body strength assessment.
- the traditional method has been to use expensive force plates in a lab based environment.
- the force plates are usually immovable (fixed in floors) or are very large and heavy to move around.
