The levels of strength, speed and power of the legs are not only an excellent indicator of performance in athletes. They can also help assess easily and non-invasively the physical condition of anyone. Hence the measurement height is reached in a vertical jump is used for decades to assess the power of the lower limbs.

To date, given its high cost, the instruments used to accurately measure the vertical jump are unique to sports biomechanics laboratory.
To solve this problem, researchers at the Autonomous University of Madrid (UAM) (Spain), Carlos Balsalobre-Fernández, Doctor of Science in Physical Education and Sports, has designed a mobile application that allows to measure the height of the vertical jump Just as it does a platform for professional forces.
According to a study recently published in the Journal of Sports Sciences study, in which 100 vertical jumps with both instruments were measured, the application provides equally reliable than a force platform laboratory, with a margin of error of measurements only 11 mm .
“The operation is very simple: a leap with the app is recorded, the images of the takeoff and landing of the jump is selected automatically, using algorithms, the vertical jump height and levels of strength, power and speed is calculated” , Balsalobre-Fernández explains.
The tool -called My Jump- works on iOS mobile devices and has already been downloaded more than 50 countries. (Source: UAM)
