Among winter sports, alpine skiing is one of the most popular and beloved disciplines because of the natural environment in which they are practiced and the satisfaction they offer.
Alpine skiing is based on the scientific basis of technique and methodology in order to continuously improve the technical processes.
Scientific research in sport has made large developments in recent years, alpine skiing adopting methods which are specific to the discipline.
This study was realized by using the OptoJump measurement and analysis system in order to optimize the explosive force.
It is an innovative system of analysis and measurement that brings a new philosophy of assessment and optimisation of performance to the world of competitive sport: it is designed for the development of a specific and customized training programme for the athlete, based exclusively on precise objective data.
In order to create the athletes' training program the initial testing of the explosive force was done by applying the Jupm Counter Movement.
Test which involves a single jump starting from an upright position with hands on hips and with counter movement.
- Rest hands on hips (to measure leg performance instead of arm performance)
- Stand straight up for 1-2 seconds
- Jump as high as you can!
- Land with normal flexion and stand still in neutral position for 1-2 seconds
Single jump starting with straight legs and performing a natural flexion before takeoff. In the counter movement jump during the breaking phase elastic energy is stored in the muscles and tendons and then utilized in the following propulsion (concentric) phase.
The OptoJump measurement and analysis system records the results directly during the test and displays them in the form of graphics, tables and video images. | Keywords
