Dynamic stability change assessed by a modified version of the Star Excursion Balance Test (SEBT). For this, Octobo-Balance device will be used. |
Five lower limb excursion directions are going to be analysed: anterior (SEBT-A), medial (SEBT-M), posterior (SEBT-P), posteromedial (SEBT-PM) and posterolateral (SEBT-PL), with all these excursion directions and the legs' length of each player we will calculate the sum of them. The device system consists of an extending measuring tape magnetized to an octagon-shaped platform which allows to measure the different directions. There is a marked point in the middle of the octagon where players must put one of their feet properly and push the measuring tape with the other one. Players will have to go as far as possible in each direction without touching de floor or lifting the foot that it's set on the octagon. There will be three attempts in all the excursion directions, and it will be done for each leg. |

Change in the rate of lower limb injuries measured with a Daily Injury Report |
Lower limb injuries occurrence will be recorded on a daily basis. For this purpose, one person in charge of each team, under the supervision of the researchers, will fill in an injury report. This report will include basic information about the injury, so as the location, the side of the body, the type and the mechanism of the injury and the time of injury, as well as the happening and duration of a sick leave. |
Daily from baseline until the end of the research study 4 months later |

Pain change measured with the Visual Analogue Scale |
Players will be asked to rate from 0 to 10 their general pain and their specific pain in: ankle, knee, hip and low back. |

Vertical Jump Height using the app MyJump2 |
Vertical jump is calculated analysing it on a recorded video with the help of this app. It is necessary to select manually the take-off frame and landing frame. Videos will be recorded by the researchers in the frontal plane in the same position and distance from the jumping player. Participants will be taught to perform a correct vertical jump, starting from a static position with knees and hips at 90º and the hands on the hips, as well as stretching the knees during the flight and landing. The objective is to achieve the maximum height with the jump. Total leg length (from anterior iliac spine to tiptoe in maximum plantar flexion) and height with flexed knees at 90º (measured vertically from floor to greater trochanter) will be measured to calculate the height of vertical jumps with the help of the app. |

Dynamic knee valgus measured with the programme Kinovea |
Players will be recorded from the frontal plane and in the same position for each player. Players shall perform three jumps in a row. Afterwards, with the Kinovea programme, the moment in which the highest knee valgus is produced in the landing of the different jumps will be analysed. |

Treatment adherence through an exercise tracking diary |
Players will be required to fill in a sheet in which they will be requested for whether or not they have done the corresponding exercises during the week. |
